Question on indoor navigation and face tracking - RPLidar or RGB-D camera or both
My requirement is to do indoor navigation/obstacle avoidance and also face detection and tracking using a ground robot (not UAV). I know that I can use RPLidar for creating occupancy grid maps but for face detection, Iidars will not work and I will need to use an RGB-D camera for detection and tracking. Now, I do not want to buy both a Lidar (for SLAM and navigation) and a depth sensing camera (for face detection and tracking) since it will be expensive to buy both. My question is - can I create 2D maps using an RGB-D camera and will it be fine to use it for indoor purposes in natural light and darkness also (for face detection). Or a Lidar will outperform an RGB-D camera when it comes to navigation.
