Depth value from Realsense L515 different from the physical distance.
I have captured few images of an object using realsense l515 (python SDK) to get the depth of a defect on the object. I have considered two points on the image, one above the defect (point A) and another inside the defect area (point B). While estimating the depth on these two points, distance of point A (26.97) is getting larger than that of point B (25.27). while physically the opposite is correct. I have visualized the coloured depth image for the same object, where there is clear colour difference between the defected area and area above it.

Hello Jishaanurenjith,
Thank you for contacting us.
Controlling laser power and receiver gain can help improve depth performance in some situations. You can use the preset to control the camera's laser power and the receiver gain.
