A method for off-line acceptance of intelligent equipment with multi-line laser radar

Abstract

The invention discloses an off-line acceptance method for multi-line laser radar intelligent equipment. Firstly, a scanning detection platform is established, and the scanning detection platform includes a device parking area, a scanning benchmark, a moving track, a moving car, a target object and a detection system; 2. Move the automatic driving equipment to be checked and accepted off-line to the equipment parking area, and park it at the fixed-point and directional position required by the scanning detection platform; 3. Start the scanning work of the multi-line laser radar to generate laser scanning data; Step 4. The detection system acquires Data, data processing, analysis and judgment include frequency judgment, cluster judgment, horizontal judgment and orientation judgment to obtain the acceptance judgment structure. This method can quickly and effectively detect whether the installation of multi-line laser radar is accurate, whether the function is normal, and the acceptance result Accurate, reliable, and easy to implement, the scanning inspection platform is easy to use and operate, and is especially suitable for the off-line acceptance of multi-line lidar for mass-produced automatic driving equipment.

Description

technical field [0001] The invention relates to the field of an off-line acceptance method for installation and use of a multi-line laser radar. Background technique [0002] With the rapid development of intelligent technology, the application of multi-line lidar is more and more extensive, especially the use on some automatic driving equipment is indispensable. In automatic driving equipment, multi-line lidar transmits and receives multiple The laser beam reaches the laser scanning in the range of 360 degrees, and the laser scanning data is obtained for the judgment of the surrounding environment and objects of the vehicle. Therefore, the precise installation and normal use of the multi-line lidar on the automatic driving equipment are very important, and they are the basic requirements for the automatic driving equipment to achieve safe and effective automatic driving.

Problems solved by technology

[0003] At present, there are many detection methods for whether the multi-line lidar is accurately installed and whether the function can be used normally. Some detection methods may not be applicable, may not be able to achieve a comprehensive detection of functions, can effectively detect the required normal function requirements, and can effectively detect the required accuracy, for example, to detect whether the response frequency of the laser scanning function meets the normal requirements , Detecting whether the laser scanning data has azimuth deviation, detecting whether the laser scanning data is consistent with the real scene, etc. Therefore, the existing detection methods of whether some multi-line laser radars are accurately installed and whether the functions can be used normally are not suitable for measurement.
