Structured Light Sinusoidal pattern

Hi,

Just looking for clarification on the structured light sinusoidal example in this link

https://docs.opencv.org/3.4.2/d0/de8/...

I presume this part is just the pattern generation. Is there another part being actively developed to decode the patterns so that you could create a point cloud (similar to the gray code tutorial).

Thanks in advance

i can't try (no projector), but the unwrapped phase map there is a depth map, iirc

Hi

So the unwrapped phase map is a depth map! If it’s a depth map then should I be able to create a point cloud from it in some way?

Thanks in advance

There is indeed a second tutorial on pattern decoding, right here!

Hi,

The decode tutorial is specific to the Gray code pattern, so it won’t work for the SinusoidalPattern.

But can't you adapt the sample?
