Abstract

The invention discloses a portable multi-elevation detection radar optical device and a self-adaptive scanning method thereof. The optical scanning device comprises a fixed base, a laser light source,a laser receiver, two reflectors, a telescopic driving device for controlling the angle of a first reflector, and a feedback element. The angle of a first emitting mirror is controlled to change automatically through the telescopic driving device so that the angle of reflected light is changed, and multi-elevation-angle detection is carried out; and the telescopic driving device is controlled through target related information fed back by the internal feedback element according to a certain logic judgment relationship so that the scanning rate of the laser is adaptively adjusted. Therefore, the portable radar optical device can conveniently realize self-adaptive scanning of a multi-elevation target.

Description

technical field [0001] The invention relates to the technical field of laser radar optical detection. Background technique [0002] Lidar is a device that uses laser beams to perceive surrounding objects, and reflects the position and shape of surrounding objects in the form of point cloud data. It has the characteristics of high measurement resolution and fast speed, and has been widely used in surveying and mapping, navigation and many other field. [0003] At present, the scanning of multi-elevation-angle targets by laser radar is mostly realized by light control array technology and servo device. Among them, optical control array technology is mostly used in large-scale equipment, and it is not cost-effective for small-scale equipment, and it is not easy to realize; while the high manufacturing cost of servo devices, long-term work is easy to wear, resulting in inaccurate rotation accuracy and inconvenient transportation, which cannot achieve portability, but If there ...
