Measuring the depth using a laser pattern projector and a single camera
Hello, everyone.
I have a robotic hand that has a laser projector and a camera with a red lens (after reading, I found that this red lens is an IR filter. Please, correct me if wrong). I am new to computer vision.
After searching, I found that there is a technique to reconstruct the 3D shape using laser pattern recognition (like dots or lines). Then, the depth can be measured using on this laser pattern and the red filtered camera.
Please, let me know if it is possible to use OpenCV to measure the change in depth directly based on the detected laser pattern. I found that there is a way to detect a single laser spot, but I am not sure if I can track the whole pattern spots to get the depth using a library made specifically for this aim.
Thank you.
