Abstract
A system and method for obtaining a target image are provided. The system includes: a floodlight illumination source configured to provide illumination of a first wavelength for a target area; a first acquisition camera configured to acquire a target floodlight image of the first wavelength of the target area; a structured light projector configured to project a structured light image of a second wavelength to the target area; a second acquisition camera configured to acquire the structured light image of the target area; and a processor, connected to the floodlight illumination source, the first acquisition camera, the structured light projector, and the second acquisition camera, and configured to: acquire the target floodlight image and the structured light image; recognize a foreground target in the floodlight image; and extract a target structured light image based on a relative position relationship between the first acquisition camera and the second acquisition camera.
