I am planning to use a Kinect Sensor on a mobile robot for path planning based on facial detection.
Assuming I am able to detect the faces of 5 individuals in a room (both the environment and the people are static), can I somehow get the coordinates of said faces, and use those as reference points to draw a path the robot should follow (using a Nearest Neighbor algorithm for example) while stopping at those individual points for 5 seconds? Can you indicate me to any resources, papers, or GitHub repositories explaining it? Also, would I need any odometry or can it all be done through Computer Vision?
Note: once detected, the faces' coordinates need to be memorized as there is no guarantee that they will remain visible throughout the entire process.
