Title:
レーザレーダシステム及びその制御方法、走査角度の取得方法、車両
Document Type and Number:
Japanese Patent JP7309743
Kind Code:
B2
Abstract:
The present invention provides a lidar system and a control method thereof, a method for obtaining a scanning angle, and a vehicle. The lidar system includes: a light source, an optical transmission module, a scanning module, and a detection module, where the light source, the optical transmission module, and the scanning module are sequentially arranged along a first optical path; the scanning module, the optical transmission module, and the detection module are sequentially arranged along a second optical path; In the first optical path, the light source is configured to transmit a laser beam, the optical transmission module is configured to transmit the laser beam, which is transmitted by the light source, to the scanning module, and the scanning module is configured to reflect the laser beam, which is transmitted by the optical transmission module, a three-dimensional space to scan the three-dimensional space. In the second optical path, the scanning module is configured to reflect a laser beam echo signal to the optical transmission module, the optical transmission module is configured to reflect the laser beam echo signal, which is reflected by the scanning module, to the detection module, and The detection module is configured to receive and process the laser beam echo signal reflected by the optical transmission module, to obtain information on an obstacle in a three-dimensional space, where the laser beam echo signal is formed by the obstacle in the three-dimensional space by reflecting the laser beam reflected by the scanning module. The lidar system according to embodiments of the present invention has a small size, high heat dissipation performance, a high signal-to-noise ratio, a large optical aperture, and a wide field-of-view angle, thereby improving overall performance.
