from rgb to depth

[rastinrastini]

Dear,
i want to reconstruct environment from video that captured from camera.
for first step want to create depth from image. had used monodepth on teddy dataset and generated depth images.
convert them to pgm with imagemagic.
but cant run code with these images and get error.
error reading file 'Teddy/estimate_depth/0000.pgm'

any way that can do this?

Have you tried specifying the full path to the sequence directory? (Failing which, what's your working directory?)

[rastinrastini]

this is my command: ./build/Apps/InfiniTAM/InfiniTAM /media/rastin/projects_drive/ai/autonomous_uav/datasets/Teddy/calib.txt /media/rastin/projects_drive/ai/autonomous_uav/datasets/Teddy/estimate_depth/%04i.ppm /media/rastin/projects_drive/ai/autonomous_uav/datasets/Teddy/estimate_depth/%04i.pgm

this is an sample of pgm https://imgur.com/a/p7b6g0N

Ok fair enough. What's the file format? When I run ImageMagick's identify tool on one of the Teddy sequence images, I get this:

0000.pgm PGM 640x480 640x480+0+0 16-bit Grayscale Gray 614417B 0.000u 0:00.002

What do you get with your files?

identify teddy_frames/0000.pgm:

PGM 640x480 640x480+0+0 16-bit Grayscale Gray 614417B 0.000u 0:00.010

identify estimated_frame/0000.pgm:

PGM 640x480 640x480+0+0 8-bit Grayscale Gray 307215B 0.010u 0:00.010

[rastinrastini]

when i use

mogrify -depth 16 -format pgm *.png

image convert to 16-bit and infinitam work. but dont reconstruct anything and screen is black

identify now:
identify teddy_frames/0001.pgm:

PGM 640x480 640x480+0+0 16-bit Grayscale Gray 614417B 0.000u 0:00.010

identify estimated_frame/0001.pgm:

PGM 640x480 640x480+0+0 16-bit Grayscale Gray 614417B 0.000u 0:00.009

[rastinrastini]

anyone has any idea how correct it?

[victorprad]

are there any comments in the pgm? the infinitam reader does not support comments in the file

[sgolodetz]

Also, is the scale of the depth values reasonable? If you can load the depth images but you get a black screen when you try to do the reconstruction, that might be worth double-checking.

[rastinrastini]

how can know is comment there? one sample of it is uploaded. https://gofile.io/d/uRwR5b
what must be scale of depth? i only convert it by command show above.
when i use command

mogrify -depth 16 -format pgm -compress none *.png

and open one of pgm files with text editor, in top of that is:

P2
640 480
65535

and dont see any comment

[rastinrastini]

any scale or characteristics needed for pgm files?
