TF-Luna Pixel Tracking

Hello everyone,
I was testing my TF-Luna with my hand, and while the program was working fine, I noticed that when tracking the distance of my hand from the camera, my hand must be in a very narrow line of sight of the camera. My question is: is there a way to make the camera track a certain pixel location or pixel region, and determine the distance of the thing in that pixel region? Say if my hand was in the pixel region of a square with corners (x1,y1) and (x2,y2), would there be a way to make the camera only scan the distance of what is in the region of (x1, y1) (x2,y2)? Thanks so much!

Not quite sure what you mean, but the counseling may have something to do with FOV.
It may be necessary to replace the FOV lidar with a larger one or to adjust the mounting angle of the tf-luna to your desired monitoring position.
