Abstract

The invention discloses a laser emitting device and an automatic tracking method to achieve rapid and accurate automatic tracking on a moving laser receiver target. The laser emitting device comprises a laser installation platform and a bottom frame. The laser installation platform comprises a laser emitter used for emitting modulation laser signals, a laser emitter rotating mechanism used for driving the laser emitter to rotate, a laser emitter rotating control unit used for controlling the rotating speed of the laser emitter and automatically tracking a laser receiver, an automatic leveling mechanism used for leveling the laser emitter, and a communication unit used for receiving rotating speed data of the laser emitter and emitting laser emitting angle data. The bottom frame comprises a three-foot frame supporting the whole laser installation platform and a laser installation platform lifting unit used for ascending and descending of the laser installation platform.

Description

technical field [0001] The invention belongs to the technical field of automatic positioning, in particular to a laser emitting device and an automatic tracking method. Background technique [0002] Precise positioning technology is one of the basic technologies to realize the automatic driving of farmland operation machinery and prescription agriculture. It has a wide range of applications in many operations such as target spraying, precision fertilization, harvesting and yield measurement, and automatic planting. It is a modern intelligent An important content of agricultural machinery research. Due to the advantages of small size, light weight, fast speed and small error, laser is widely used in horizontal and vertical calibration in the construction industry, but the research on positioning has just started. In the laser dynamic positioning system, the laser transmitter emits laser signals and automatically tracks the center of the laser receiving target without missing...
