I also don't understand, why I can choose under Profiles in the DepthProfile_800 the Format, but this is not working as I would expect. After switching from "PB_FORMAT_UNKNOWN" to "OB_FORMAT_GRAY" which seem to be my target, it just throws some errors.
Thank you for your feedback. I'll forward the issue to our Unity development engineer.

DepthProfile not support OB_FORMAT_GRAY format, OB_FORMAT_UNKNOWN means any format that support by DepthProfile, use this by default.
hey there, I wrote an issue in the unity section here
Because there is no activity since weeks, I decieded to write here. I'm a bit lost with the examples. I just want to extract some depth infomations. But the only thing I can see is a black&red image where the red color is the same in very different depths. Best case would be to get an grayscale image, where the pixel show a mapped image from for example 1-5 meter, adjustable range if possible.
I bought the astra 2 with the hope to use it in an installation and buy more of them, but currently it's not useable for me.
I use openCV to extract infos from the image. Currently it's a webcam image, but it'a difficult environment and a depth sensor would work much better. I hope, someone can help.
You can get the depth value from OrbbecFrameSource.GetDepthFrame().data, it's a depth value array, you can use it as depth image data with width and height, and normalize the value to 0~1 use OpenCV or any other method you like.
Thank you for the response. I'm not so good in coding to understand how to handle all these bytes... I'm more from the visible side of life... I think in pixel and am not so good on in my eyes complex coding stuff. But still, I manages to ask ChatGPT about it and now have a working example using also the recommended line.
Still I wonder, if body tracking is an option for the unity sdk like in this demo from three years ago...
Meanwhile I have some ugly problems getting the app runing on windows... but this is another story and I'll open a new issue for this.
And it would be nice to get an answer, if I should write here or in the OrbbecUnitySDK issue section. Or if it's not moderated.

I convert depth to Unity Texture like this:
Texture2D depthTexture = new Texture2D(frame.width, frame.height, TextureFormat.RGB24, false);
ColorizeDepth(frame.data);
depthTexture.LoadRawTextureData(depthBuffer);
depthTexture.Apply();
private byte[] ColorizeDepth(byte[] depthData)
{
int bufferSize = depthData.Length / 2 * 3;
byte[] depthBuffer = new byte[bufferSize];
int length = depthData.Length;
for (int i = 0; i < length / 2; i++)
{
short depth = (short)((depthData[i * 2 + 1] << 8) + depthData[i * 2]);
byte depthByte = (byte)0;
if (depth != 0)
{
depthByte = (byte)(255 - (255 * depth / 10000.0f));
}
depthBuffer[i * 3 + 0] = depthByte;
depthBuffer[i * 3 + 1] = depthByte;
depthBuffer[i * 3 + 2] = depthByte;
}
return depthBuffer
}
