Here you are using ngv_box3dpolygon function in the PostgreSQL. Since I can not find it anywhere in PostgreSQL, nor in PostGis extension, I guess it is your function.
Could you add your defined functions in the PostgreSQL database?

Hey, I tried reading the RGB images from the .tiffs generated by the managed code. They look fine but the stencil looks weird. I'm reading it using the code provided in the generate_bboxes.py and get the following result if I display the image.

What did I mess up?
Can you help me?

Code used:
imgpath = data_dir + filename + ".tiff"
tiffimg = TIFF.open(str(imgpath))
img = Image.open(str(imgpath))
w = img.width
h = img.height
del img
image = np.empty((h, w, 4), dtype=np.uint8)
depth = np.empty((h, w), dtype=np.float32)
stencil = np.empty((h, w), dtype=np.uint8)
TIFF.setdirectory(tiffimg, 0)
TIFF.readencodedstrip(tiffimg, 0, image.ctypes.data, -1)
lastdir = num_directories(tiffimg) - 1
TIFF.setdirectory(tiffimg, lastdir - 1)
TIFF.readencodedstrip(tiffimg, 0, depth.ctypes.data, -1)
TIFF.setdirectory(tiffimg, lastdir)
TIFF.readencodedstrip(tiffimg, 0, stencil.ctypes.data, -1)
cv2.imshow("mask", stencil)
cv2.waitKey(0)

Hi, the ngv_get_bytes(localpath, imagepath) which is used in ngv_get_bytes(id integer) and ngv_get_raster(archive text, image text) is not found, and thus these functions fail to be created.

This does not break the functionality, because these functions are not being used in the post-processing script, as far as I could see, but it would be nice to have it working without errors.

Hi,

I have problems using your post processing scripts.

1. I start generate_bboxes.py with: python generate_bboxes.py --session 1 --dataroot Data --pixel_path Data
   The zip file is extracted in "Data/'runguid'" and the npz files are under "Data"
2. Then I start genvoc.py with: python genvoc.py --out TestOut --image_path Data/bca0a265-0e7f-415b-a41f-2052b7517d0e --pixel_path Data --query "SELECT * FROM detections JOIN snapshots USING (snapshot_id) JOIN runs USING (run_id) JOIN sessions USING (session_id) WHERE snapshot_id=1"
   I have a test folder "TestOut" where the files should be saved. But only empty folders are created and a png in "SegmentationObject", which is just black.
3. In this line you used some color code, which are not in the script. So I tried a list: colors = [(255,0,255), (55,0,55), (34,33,87)] Is this correct?
4. When printing out the status in generate_bboxes.py, there are always 0 detections, even if the cars are "correctly" annotated like in the images in the zip file. The fields best_bbox and coverage in table detections won't be updated also.

Can you help please?

Cheers,
