general_parking_slot_detection's Issues

车位描述定义

您好, 想请教个问题, 如果车位的A点被截断(即位于图片之外), 这样的车位需要标注么? 另外算法里回归的是AB的长度, 所以个人理解, 如果B点位于图片之外, 这种车位也不标注对么?
也就是说, 本算法所要求的标注, 只有当A, B两点(无论是否遮挡)都位于图片内时才标注该车位, 对吗?

数据集转化

你好,请问ps2.0数据集怎么转化成ps2.0_convert呢。怎么转化成fullimg数据集呢

raw demo video download

thanks for your wonderful work and open resource. Where to download the raw demo avm video without the slot detection result? thanks for you reply in advance.

权重文件大小问题

您好,我想请教一下,为什么我用train.py进行训练,用的yolox_single_scale网络模型,保存下来的权重文件有180多MB呀,我看您这边提供的权重文件有的只有9MB大小,想知道您是怎么做到的

全图预测结果不理想

您好,我直接使用了您提供的fullimg权重预测ps2.0数据集(全图),预测结果不理想,重新训练了一组权重(在ps2.0上ap达到92%)预测的结果也没有改善,请问预测的时候有什么要调整的地方吗

继续训练,载入图片报错

大佬,请教下,我使用search_hyperparams.py生成的参数json文件,但载入后报错:
File "train.py", line 299, in
dataloaders = data_loader.fetch_dataloader(params)
File "/home/lto5sgh/2023-parking-slots/general_parking_slot_detection-master/dataset/data_loader.py", line 525, in fetch_dataloader
train_ds = AutoParkingData(params, mode="train")
File "/home/lto5sgh/2023-parking-slots/general_parking_slot_detection-master/dataset/data_loader.py", line 54, in init
percentage = int(len(imgs_file) * data_ratio[1])
ValueError: invalid literal for int() with base 10: 'eee'
我在Train.py中再次添加一遍
args.train_data_ratio = [["seoul", 1]]
args.val_data_ratio = [["seoul", 1]]
即可运行,但我添加的内容和json中是一致的,请问问题点在哪儿?如下是json的配置:
"train_data_ratio": [
"seoul",
1
],
"val_data_ratio": [
"seoul",
1
],

关于训练的时候,sepline角度计算的问题

你好,非常感谢你的分享。想请教你一下,计算loss的时候,当deltanorm_or_direction是direction时,我看sepline的角度是用如下代码

x_ratio, y_ratio = 1, H / W
radian = math.atan2(marking_point.lenSepLine_y * y_ratio, marking_point.lenSepLine_x * x_ratio)

你能说明一下,为什么需要乘以y_ratio和x_ratio吗?

全图训练

您好,请问一下,全图训练看了一下您提供的train.log. (自己训练也是) 随着训练的进行, loss不断降低.。为什么average_precision精度一直在跳变。

请问下你说效果不好是目标点预测不好,还是偏移回归不好?

看到你的偏移是在归一化中的差值,可能就不是(-1,1)的均匀区间,反而可能是(-0.3,0.3)的区间。
而预测结果是用tanh函数激活的,这是不是结果不好的原因。
如果对偏移的长度单独归一化可以么?
或者说根本不是因为这个问题!而是你的图像缩嘚太小,网络模型结构不够复杂呢?
