In terms of identifying unique features of individuals, you will have you decide whether this works for you. Here is a typical output of the this TOF sensor looking at a person. This is a depth image, but a point cloud output (for each frame) is also available. In order to build a map, you would need to use some mapper software (we provide a reference such as https://docs.modalai.com/voxl-mapper/). However you would need to be familiar with mapping algorithm(s) and learn how the software components work in order to get mapping to work well and tune it for your application.
