Abstract
(EN)
The invention provides a three-dimensional scanning laser radar based on an MEMS micromirror. The three-dimensional scanning laser radar comprises an emitting module, a receiving module, a high-voltage module, a counterweight module, a scanning module, a control module and a wireless transmitting module, wherein the emitting module is used for scanning and emitting in a vertical direction; the receiving module is used for receiving an echo signal reflected by an object to be detected; the high-voltage module is used for providing high voltages for transmission and reception; the counterweightmodule is used for dynamically balancing an entire rotating body; the scanning module is used for rotationally scanning in a horizontal direction and outputting an angle; the control module is used for controlling the whole machine and running an algorithm; the wireless transmitting module is used for wireless power supply and data transmission. The three-dimensional scanning laser radar adopts asingle laser diode as the emitting module to irradiate the MEMS micromirror and scan in the vertical direction, the receiving module performs reception in the vertical direction, the emitting module and the receiving module are integrated, and the scanning module rotates at 360 degrees in the horizontal direction to realize three-dimensional scanning. The three-dimensional scanning laser radar based on the MEMS micromirror provided by the invention has the advantages of compact structure, dense dot matrix pixels, and convenient assembly and adjustment.
