Click on a pixel in the left view stream and show the Depth reading from that pixel location

I’m trying to figure out how to return the depth measurement reading from clicking on a pixel location in the left view video stream using python

Once you have the position of your pixel, you can retrieve the depth value by using get_value() on your sl.Mat.
See the documentation : Mat Class Reference | API Reference | Stereolabs


You should take a look at this python tutorial to know how to extract depth information :

So I combined the Depth tutorial and the ZED opencv example and am now able to extract the depth reading when I clink on the image. My next question is there some sort of calibration to make sure the depth measurement is accurate?
