orthophoto_maps's Issues

about requirements

hi, can you share requirements.txt?

I have issues with python 3.8 which version should I use?

I was searching simple orthophoto generator project. I think this can meet with my requirements. thanks

gif help

hi. how did you make the gif like in this link?

Problem of geolocalisation

Hi,

I run your code without problem, but the result is not correct :

• tiff images are not well referenced
• tiff images do not overlap
• tiff images are not well orientated

My parameters :

• PH4 RTK
• epsg 4471
• flat landscape, seashore at low tide

Can I share you privately some images ?
Thanks

How to process a batch of photos

We usually use a drone to shoot orthographic picture, and it will take a bundle of photos in one orthographic shooting task. So, May I ask how can I run your code to process these photos into a single tif file?

image orientation is not correct

It's better when I use it with the test dataset, but it doesn't seem to be quite right when I use another dataset (https://dronemapper.com/software/4thAve.zip). I get an incorrect image, the image orientation is not correct.

DEM

Hello, I would like to perform orthorectified correction on a single image based on digital elevation, but I am unable to use your testOrthophoto-DM.py module to run it. Is it currently supported to translate this requirement into Hello, I would like to perform orthogonal correction on a single image based on digital elevation, but I am unable to run it using your testOrthophoto DEM. py module Is there currently any support for this requirement

Photo Dataset

Hwiyoung hi. I hope you are doing well. How do I use my own dataset? What do I need in the content of the dataset? Thank you in advance :)

Hi hwiyoung, if I want to stitch my own pic. What should I do?

I'm already building this project. But I don't know how to change the input, and what command to use in this project? Would you like to help me? Thank

Where can I get the required parameters( Omega | Phi | Kappa) from the DJI photos?

I use ExifTool to extract information from the DJI photo, however, I cannot find the corresponding parameters - Omega | Phi | Kappa. I guess they are the gimbal angles which represent the attitude of the camera. But they are not the same values.

Coordinate transformation

I have two problems to ask for you.1、What do the parameters in the txt document mean when the data is input, is it related to the latitude and longitude in the input jpg file?2、How to convert 5186 coordinates to other coordinates such as 4490 coordinates

Why is the aircraft's attitude not considered?

In the code def get_metadata(input_file), only the gimbal's attitude is being read and used, and the aircraft's attitude is not being read or used. Why is that?

libdap4 not found

$ conda env create -f environment.yaml
Collecting package metadata (repodata.json): done
Solving environment: failed

ResolvePackageNotFound: 
  - libdap4==3.20.6=hd7c4107_1

+1 question :)

hello. I really appreciate you answering my questions. I have one more question. I want to use my own revised DSM data. How can I add it into the code? please please help me :)

Orthophoto coordinates are incorrect

I successfully run the program, but the image coordinate system after loading in QGIS is not correct. May I ask why? (Using the example data provided in the repository)

Getting gps coordinates of points

Hi, this library looks very promising.

I am wondering how I could get the GPS location of points on the resulting image? So for example, if I see a building that I want to know the location of, how could I find it?

If the output is a GeoTIFF, I think I would be able to get that data, but I'm not sure what coordinate system your GeoTIFF is in, do you know?

i have this problem

hello,i use your code to study,but i have this problem,can you tell me why?
this is problem: NameError: name 'restored_image' is not defined
this problem is appear this line:bbox = boundary(restored_image, eo, R, ground_height, pixel_size, focal_length)

On the acquisition of longitude and latitude

Hello, thank you for your excellent work. I am using this project. Is there any way to obtain the longitude and latitude coordinates of the image after ortho transformation?

urgently help please

Hi Hwiyoung, when I try to run my own data file (jpg+txt) in the script I get the following error.
File c:\users...\main.py:57 in get_metadata
focal_length = convert_string_to_float(exif['Exif.Photo.FocalLength']) / 1000 # unit: m
KeyError: 'Exif.Photo.FocalLength'
Why do you think? How can I fix it?

Orthophoto_Maps/module/ExifData.py

Line 50 in 74e4ac9

focal_length = convert_string_to_float(exif['Exif.Photo.FocalLength']) / 1000 # unit: m

geotiff save

Hi Hwiyoung Kim. i'm having problems with library establisments. for example, i could not install the "pyexiv2x" library in the exifdata module in the main_dg code, it gave a lot of errors. do you have any suggestions for me about installing the libraries? i can't run the code without them. i have never been able to run it. thanks in advance :)
