Depthmaps format

[adamroszyk]

HI,
I have a depthmaps that looks like this: click

I've tried using them in your code in the form as show on the picture, and after making them grayscale, but generated point-cloud seems to be empty with those.

Any advices - how I should prepare pictures to make them work with your code ?

Regards.

Depth maps should be saved in format: 16-bit PNG, depth in millimeters.

Ok, thanks for quick answer - what about the resolution - does it have to be 640x480. or I can just change it in code - and it should work ?

[andyzeng]

Changing it should work. I haven't tested it though. Keep in mind that your camera intrinsics matrix cam_k will likely also have to change.

[adamroszyk]

Is it possible to apply different camera intrinsics to different frames ?
My frames are from iPhone, and it changes the camera intrinsics matrix every shoot.

[andyzeng]

It's possible, but you'll have to modify demo.cu so that it changes cam_K as it's looping through depth frames.

Perfect, thanks again !

hello, @adamroszyk
how do you convert image 32-bit to 16-bit as with as depth in millimeters?
