Problems solved by technology

[0008] At present, the reversing radar is ultrasonic radar, millimeter wave radar and lidar probe, and it can only detect the situation of flat ground, and it is difficult to detect the complex situation of the ground environment, such as the presence of cliffs, potholes and small mountains on the ground, etc.
[0009] Vehicle-mounted images generally use VGA cameras, which have poor clarity, small viewing angles and blind spots, and are greatly affected by light.

Abstract

The invention discloses a dumper reversing detection method. The method comprises the following specific steps: allowing a multi-line laser radar installed on a tail cross beam of a dumper to emit multi-line laser, detecting surroundings, receiving reflected laser, generating laser point cloud data of a dumper reversing environment and sending the laser point cloud data to a computing device, allowing the computing device to receive the laser point cloud data of the laser radar, and performing computing process to form the dumper reversing detection method. According to the dumper reversing detection method, the problem of reversing detection of automatic driving of the dumper under uneven and complex road conditions such as cliff, pit hole and small mountain body is solved. The reversingsafety of the dumper in a complex environment is guaranteed, and the production and transportation efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a dump truck reversing detection method. Background technique [0002] The automatic driving of dump trucks can reduce transportation costs and improve economic benefits. The driving environment and road conditions in the process of automatic driving of dump trucks are more complex, so the reverse detection of dump trucks has high research significance and value. [0003] Existing scheme: [0004] At present, the reversing detection system mainly includes two kinds of equipment: distance detection radar and real-time image. Detection radar includes ultrasonic radar and millimeter wave radar, lidar and so on. [0005] The effective detection distance of ultrasonic radar is only a few meters, and it is difficult to identify low objects, and the existing technology is difficult to converge ultrasonic waves to a small range, and it is difficult to realize obstacle detection in ...
