Arducam Stereo camera Depth Measurement

Hi,

I purchase this Arducam stereo camera kit from uctronics.

I worked on a depth measurement project and used link:

I tried many time to get proper depth measurement as shown in video but still not getting success.

I feel that if I setup both camera in proper alignment like same height & width in video object then I got proper depth.

Would you like to suggest to me some proper setup mounted two stereo cameras on it ?

Also,

Please give me guidance on how to calculate distance using the colour shown on the video of depth measurement.

Please help me with this information is very important to complete my product.

Thanks,
Kamesh Darji
