EMSANet: Efficient Multi-Task RGB-D Scene Analysis for Indoor Environments

EMSANet: Efficient Multi-Task RGB-D Scene Analysis for Indoor Environments

Updated on 2023-03-29 for our follow-up works EMSAFormer and Panoptic Mapping.

This repository contains the code to our paper "EMSANet: Efficient Multi-Task RGB-D Scene Analysis for Indoor Environments" (IEEE Xplore, arXiv)

Our efficient multi-task approach for RGB-D scene analysis (EMSANet) simultaneously performs semantic and instance segmentation (panoptic segmentation), instance orientation estimation, and scene classification.

This repository contains the code for training, evaluating, and applying our networks. Furthermore, we provide code for converting the model to ONNX and TensorRT, as well as for measuring the inference time.

   Please follow the instructions given in ./lib/nicr-scene-analysis-datasets or HERE to prepare the datasets. In the following, we assume that they are stored at ./datasets

   Use --instances-version emsanet when preparing the SUNRGB-D dataset to reproduce reported results. See notes in evaluation section for more details.

Results & Weights

We provide the weights for our selected EMSANet-R34-NBt1D (with ResNet34 NBt1D backbones) on NYUv2 and SUNRGB-D*:

Dataset	Model	mIoU	mIoU**	PQ	RQ	SQ	MAAE	bAcc	FPS***	URL
NYUv2 (test)	EMSANet-R34-NBt1D	50.97	50.54	43.56	52.20	82.48	16.38	76.46	24.5	Download
	ESMANet-R34-NBt1D (pre. Hypersim)	53.34	53.79	47.38	55.95	83.74	15.91	75.25	24.5	Download
SUNRGB-D (test)	EMSANet-R34-NBt1D	48.39	45.56	50.15	58.14	84.85	14.24	61.83	24.5	Download
	EMSANet-R34-NBt1D (pre. Hypersim)	48.47	44.18	52.84	60.67	86.01	14.10	57.22	24.5	Download

* Note that the results will slightly differ if you run the evaluation on your own due to an unexpected overflow during panoptic merging that was fixed along with preparing the code for the release. However, the obtained results tend to be slightly better. For more details, see the evaluation section below.
** This mIoU is after merging the semantic and instance segmentation to the panoptic segmentation. Since merging is focused on instances, the mIoU might change slightly compared to the one obtained from semantic decoder.
*** We report the FPS for an NVIDIA Jetson AGX Xavier (Jetpack 4.6, TensorRT 8, Float16) without postprocessing (as it is not optimized so far). Note that we only report the inference time for NYUv2 in our paper as it has more classes than SUNRGB-D. Thus, the FPS for SUNRGB-D can be slightly higher (37 vs. 40 classes).

We further provide the pre-training checkpoints we used for the mentioned "pre. Hypersim" results for NYUv2 and SUNRGB-D. Note that the training was done with additional normal estimation task.

Download and extract the models to ./trained_models.

Check out our follow-up works EMSAFormer and Panoptic Mapping for even better results and experiments on the ScanNet dataset as well.

Evaluation

To reproduce results for the full multi-task approach, use main.py together with --validation-only.

Note that building the model correctly depends on the respective dataset and the tasks the model was trained on.

Note that the results below slightly differ due to an unexpected overflow during panoptic merging that was fixed along with preparing the code for the release. However, the results below tend to be slightly better.

On Apr 20, 2023, we further fixed a small bug in the instance task helper: the MAAE metric object was not reset after computing the metric value (at the end of an epoch), which led to wrong results for valid_orientation_mae_gt_deg in consecutive validations. The values reported below are fine as they were computed in a single validation. However, the results reported in our paper slightly differ due the mentioned bug. Use the values below to compare to our approach.

SUNRGB-D

We refactored and updated instance annotation creation from 3D boxes for SUNRGB-D in nicr-scene-analysis-datasets == 0.6.0. The resulting annotations feature a lot of more instances; however, it is also changing the ground truth for the evaluation below. For more details and a comparison between both versions, we refer to our follow-up work Panoptic Mapping(GitHub, arXiv) that proposes the refined annotations. To reproduce reported EMSANet paper results either use nicr-scene-analysis-datasets >= 0.7.0 and prepare the SUNRGB-D dataset with --instances-version emsanet (or go back with both reposities and use nicr-scene-analysis-datasets <= 0.6.0). For backward compatibility, i.e., to still be able to load a SUNRGB-D dataset prepared with nicr-scene-analysis-datasets < 0.7.0, you can pass --sunrgbd-instances-version anyold to main.py; however, use this only if you know what you are doing!
We recommend re-preparing the SUNRGB-D dataset with nicr-scene-analysis-datasets >= 0.7.0 as described above to avoid any confusion.

To evaluate on SUNRGB-D (without pretraining on Hypersim), run:

python main.py \
    --dataset sunrgbd \
    --dataset-path ./datasets/sunrgbd \
    --sunrgbd-instances-version emsanet \

Inference

We provide scripts for inference on both samples drawn from one of our used datasets (main.py with additional arguments) and samples located in ./samples (inference_samples.py).

Note that building the model correctly depends on the respective dataset the model was trained on.

Dataset Inference

To run inference on a dataset with the full multi-task approach, use main.py together with --validation-only and --visualize-validation. By default the visualized outputs are written to a newly created directory next to the weights. However, you can also specify the output path with --visualization-output-path.

Example: To apply EMSANet-R34-NBt1D trained on NYUv2 to samples from NYUv2, run:

python main.py \
    --dataset nyuv2 \
    --dataset-path ./datasets/nyuv2 \
    --tasks semantic scene instance orientation \
    --enable-panoptic \
    --input-modalities rgb depth \
    --rgb-encoder-backbone resnet34 \
    --rgb-encoder-backbone-block nonbottleneck1d \
    --depth-encoder-backbone resnet34 \
    --depth-encoder-backbone-block nonbottleneck1d \
    --no-pretrained-backbone \
    --weights-filepath ./trained_models/nyuv2/r34_NBt1D.pth \
    --validation-batch-size 4 \
    --validation-only \
    --visualize-validation \
    --visualization-output-path ./visualized_outputs/nyuv2 \
    --skip-sanity-check \
    --wandb-mode disabled

Similarly, the same can be applied to SUNRGB-D (see parameters in evaluation section).

Sample Inference

Use inference_samples.py to apply a trained model to the sample from a Kinect v2 given in ./samples.

Note that the dataset argument is required to determine the correct dataset configuration (classes, colors, ...) and to build the model correctly. However, you do not need to prepare the respective dataset. Furthermore, depending on the given depth images and the used dataset for training, an additional depth scaling might be necessary. The provided example depth image is in millimeters (1m equals to a depth value of 1000).

Examples:

• To apply our EMSANet-R34-NBt1D trained on NYUv2 to the samples, run:

  python inference_samples.py \
      --dataset nyuv2 \
      --tasks semantic scene instance orientation \
      --enable-panoptic \
      --rgb-encoder-backbone resnet34 \
      --rgb-encoder-backbone-block nonbottleneck1d \
      --depth-encoder-backbone resnet34 \
      --depth-encoder-backbone-block nonbottleneck1d \
      --no-pretrained-backbone \
      --input-modalities rgb depth \
      --raw-depth \
      --depth-max 10000 \
      --depth-scale 1 \
      --instance-offset-distance-threshold 40 \
      --weights-filepath ./trained_models/nyuv2/r34_NBt1D_pre.pth

  

• To apply our EMSANet-R34-NBt1D trained on SUNRGB-D to the samples, run:

  python inference_samples.py \
      --dataset sunrgbd \
      --sunrgbd-depth-do-not-force-mm \
      --tasks semantic scene instance orientation \
      --enable-panoptic \
      --rgb-encoder-backbone resnet34 \
      --rgb-encoder-backbone-block nonbottleneck1d \
      --depth-encoder-backbone resnet34 \
      --depth-encoder-backbone-block nonbottleneck1d \
      --no-pretrained-backbone \
      --input-modalities rgb depth \
      --raw-depth \
      --depth-max 8000 \
      --depth-scale 8 \
      --instance-offset-distance-threshold 40 \
      --weights-filepath ./trained_models/sunrgbd/r34_NBt1D.pth

  

Note that the models are not trained on that kind of incomplete depth images. Moreover, training on NYUv2 means that no images from Kinect v2 were present at all (NYUv2 is Kinect (v1) only).

Note that the --instance-offset-distance-threshold argument is used to assign an instance ID of 0 to pixels if they have a distance greater than 40 pixels from the nearest center. During panoptic merging, these pixels are assigned to the void class.

Time Inference

Note, for newer versions of TensorRT onnx2trt is not required (and also not available) anymore. Pass --trt-use-get-engine-v2 to inference_time_whole_model.py to use TensoRT's Python API instead.

We timed the inference on an NVIDIA Jetson AGX Xavier with Jetpack 4.6 (TensorRT 8.0.1.6, PyTorch 1.10.0).

Reproducing the timings on an NVIDIA Jetson AGX Xavier further requires:

• the PyTorch 1.10.0 wheel from NVIDIA Forum (see the instruction to install TorchVision 0.11.1 as well)
• the NVIDIA TensorRT Open Source Software (onnx2trt is used to convert the onnx model to a TensorRT engine)
• the requirements and instructions listed below:

  # do not use numpy>=1.19.4 or add to .bashrc "export OPENBLAS_CORETYPE=ARMV8"
  pip3 install -U numpy<=1.19
  
  # pycuda
  sudo ln -s /usr/include/locale.h /usr/include/xlocale.h
  pip3 install pycuda>=2021.1
  
  # remaining dependencies
  pip3 install dataclasses==0.8
  pip3 install protobuf==3.19.3
  pip3 install termcolor==1.1.0
  pip3 install 'tqdm>=4.62.3'
  pip3 install torchmetrics==0.6.2
  
  # for visualization to fix "ImportError: The _imagingft C module is not installed"
  sudo apt-get install libfreetype6-dev
  pip3 uninstall pillow
  pip3 install --no-cache-dir pillow
  
  # packages included as submodules in this repository
  pip install -e ./lib/nicr-scene-analysis-datasets
  pip install -e ./lib/nicr-multitask-scene-analysis

Subsequently, you can run inference_time.bash to reproduce the reported timings.

Training

Use main.py to train EMSANet on NYUv2, SUNRGB-D, Hypersim, or any other dataset that you implemented following the implementation of the provided datasets.

Note that training EMSANet-R34-NBt1D requires the pretrained weights for the encoder backbone ResNet-34 NBt1D. You can download our pretrained weights on ImageNet from Link.

Note that we trained all models on NVIDIA A100-SXM4-40GB GPUs with batch size of 8. However, training the full multi-task approach requires only ~14GB of VRAM, so a smaller GPU may also be fine. We did not observe any great boost from larger batch sizes.

Example: Train our full multi-task EMSANet-R34-NBt1D on NYUv2:

python main.py \
    --results-basepath ./results \
    --dataset nyuv2 \
    --dataset-path ./datasets/nyuv2 \
    --input-modalities rgb depth \
    --tasks semantic scene instance orientation \
    --enable-panoptic \
    --tasks-weighting 1.0 0.25 3.0 0.5 \
    --instance-weighting 2 1 \
    --rgb-encoder-backbone resnet34 \
    --rgb-encoder-backbone-block nonbottleneck1d \
    --depth-encoder-backbone resnet34 \
    --depth-encoder-backbone-block nonbottleneck1d \
    --encoder-backbone-pretrained-weights-filepath ./trained_models/imagenet/r34_NBt1D.pth \
    --validation-batch-size 16 \
    --validation-skip 0.0 \
    --checkpointing-skip 0.8 \
    --checkpointing-best-only \
    --checkpointing-metrics valid_semantic_miou bacc mae_gt_deg panoptic_deeplab_semantic_miou panoptic_all_with_gt_deeplab_pq \
    --batch-size 8 \
    --learning-rate 0.03 \
    --wandb-mode disabled

To reproduce the results reported in our EMSANet paper for SUNRGB-D, make sure to prepare and use the correct dataset version for SUNRGB-D (see note in evaluation section).

For more options, we refer to ./emsanet/args.py or simply run:

EMSA Net Evaluation Error

Hello, I have issue running EMSANet. I followed all steps, tried creating both environments (with cuda11.7 and cuda11.3), I downloaded and extracted datasets models using your processing repo, but when I run any model I get sometimes this error:

Can you please explain me what is problem here?

Sample Inference works (but not Dataset Inference)

Hypersim dataset

Hello! Congratulations on your great work and attributions! But I find your dataset Hypersim is hard to get, though you have refered to how to prepare the datasets. However, it needs extra money with the Hypersim Link's page can't be found.

Loading pre-trained resnet50

I have a question regarding loading a ResNet model other than ResNet-34. I tried to use ResNet-50 with the pre-trained weights provided by PyTorch, but the ResNet-50 model generated from class ResNetBackbone(Backbone) is different from the pre-trained model from PyTorch.

Loaded pre-trained model from pytorch:

From class ResNetBackbone(Backbone):

Could you please tell me how to properly load the pre-trained ResNet-50?
Thank you so much.

Sorry, I can not download normals_gt.tgz！！！！！！

Train using multi-gpu

Dear authors,

Would it be possible to train the model using multi-gpus?

What is the configuration of pertraining on hypersim ?

Epoch, Task weighting or the other settings, can you show the training command on hypersim ?

Is it possible to use Cityscapes Dataset?

Greetings,

Hi. This is fascinating to see panoptic segmentation with rgb and depth image combine. And I'm thinking to use Cityscapes Dataset to your model (as what you've done with ESANet for semantic segmentation). Is it possible to use Cityscapes Dataset on this model?

Thank you in advance.

About the inference metric

Dear authors,

Hello, thank you for your great work.
I have a question regarding the inference outputs.
Could you please tell me how the two metrics, 'valid_panoptic_deeplab_semantic_miou' and 'valid_semantic_miou' are different?

The normal task

I wonder whether the normal task is working, it is possible to visualize the normal task？

How to Export train model output to video format

How do I export the train model output to video format as shown in your youtube video am referring to this link: https://www.youtube.com/watch?v=-Sopja6UEJg&t=0s

Thanks

Cityscapes Visualization

Dear author,

I conducted training using the Cityscapes dataset and attempted to visualize the results using the "inference_samples.py" script. However, I encountered an issue with the instance segmentation output, wherein a single object appeared to be split into multiple distinct objects. This problem also had an impact on the semantic (panoptic) segmentation result.

How can I properly visualize the instance segmentation for cityscapes?

Thank you so much for your time.

May I ask what code changes are required to train my own dataset?

May I ask what code changes are required to train my own dataset? Thank you very much.

main.py: error: argument action: invalid choice: '--tasks semantic scene instance orientation' (choose from 'resume')

I'm trying to run the evaluation on NYUv2 (without pretraining on Hypersim), but I keep receiving this error, I had the problem discussed in #16

So I commented the line, run it again and receivedthe error:

main.py: error: argument action: invalid choice: '--tasks semantic scene instance orientation' (choose from 'resume')

It looks like the "--tasks" which is assigned as "semantic scene instance orientation", but it should be resume, correct?

The class 0 of semantic labels

Thanks for your excellent work. I read the code carefully. And I notice that when calculating the CE loss and the miou, the class 0 seems to be ignored, why?
