Abstract

The invention discloses an intelligent laser radar device, system and data processing method. The device comprises a monocular camera, a laser radar, a mechanical component and an embedded processingterminal, wherein the monocular camera, the laser radar and the embedded processing terminal are all installed on the mechanical component; the monocular camera is connected with the embedded processing terminal through a camera data line; the laser radar is connected with the embedded processing terminal through a radar data line; and the embedded processing terminal outputs processed data through a fusion data line. The real-time information of the laser radar and the monocular camera fusion is fused; the camera data is subjected to semantic segmentation through a deep learning algorithm; the information fusion is carried out through a pose relation between the camera and the laser radar; the intelligent laser radar system is realized; the data is output through the same data link; and the modularization and synchronization of the system are improved.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to an intelligent laser radar device, system and data processing method thereof. Background technique [0002] The core connotation of autonomous driving includes four parts: positioning, perception, decision-making, and execution. The main function of the perception layer is to collect and process environmental information and in-vehicle information, such as vehicle speed, direction, motion posture, and traffic conditions, etc. The decision-making layer outputs information. This link involves various technologies such as road boundary detection, vehicle detection, pedestrian detection, etc. The sensors used generally include laser radar, camera, millimeter wave radar, ultrasonic radar, etc. Since each sensor has its own limitations when designing, a single sensor cannot meet the precise perception under various working conditions. If you want the vehicle to run smoothly in various...
