Laser radar, data processing method, data processing module and medium

The invention discloses a laser radar, a data processing method, a data processing module and a medium, the laser radar comprises a rotary scanning mechanism, a receiving optical module, an echo detection module and an image acquisition module, and the rotary scanning mechanism is suitable for rotating through a mechanical device; the receiving optical module is suitable for transmitting incident light to the echo detection module and the image acquisition module in the rotating process of the rotary scanning mechanism; the echo detection module is suitable for acquiring an echo signal from the incident light emitted by the receiving optical module to obtain echo detection information; and the image acquisition module is suitable for converting the incident light incident through the receiving optical module into a corresponding electric signal to obtain image information. By adopting the scheme, the view field matching degree and the time synchronization between the image data and the point cloud data can be improved, and the accuracy of the image data and the point cloud data can be ensured.
