Equipment and Methods for Providing Depth Mapping Along with Scanning of Laser Image Projections

摘要

An apparatus for combining image projection with surface scanning is described herein. In general, the apparatus and method utilize at least one light source of laser light (102) to generate laser light (102), and a scanning mirror (104) that reflects the laser beam into a pattern of scan lines. Prepare. Selectively generating projected image pixels during the first portion of the scan line pattern and selectively generating a depth mapping pulse during the second portion of the scan line pattern So that the light source is controlled. Projected image pixels generate a projected image, and depth mapping pulses are reflected and received from the surface and used to generate a three-dimensional point cloud that indicates the measured surface depth at each point. Is done. Thus, during each scan of the pattern, both a projected image and a surface depth map can be generated. [Selection] Figure 1
