Miniature solid-state laser radar and data processing method therefor

A miniature solid-state laser radar, comprising a laser emitter, an imaging lens, an imaging sensor, and a control and data processing apparatus, wherein

• the laser emitter is used to emit linear laser;
• the imaging lens is used to collect reflected laser light and image same on the imaging sensor;
• the imaging lens is an asymmetric optical lens which has an asymmetric focusing characteristic;
• an equivalent focal length of the imaging lens in a direction of a connecting line between the laser emitter and the imaging lens is greater than an equivalent focal length in a direction which is perpendicular to the connecting line between the laser emitter and the imaging lens;
• the imaging sensor receives the light focused through the imaging lens and images the same;
• the control and data processing apparatus is used to control the laser emitter to work, receive imaging data of the imaging sensor and operate a structural light algorithm to finally acquire point cloud data in a space environment;
• after the light emitted by the laser emitter irradiates a surface of an object, the light is reflected by the surface of the object, is then received by the imaging lens, and is finally imaged on the imaging lens;
• and the laser emitter and the imaging sensor are both electrically connected with the control and data processing apparatus.
