Problems solved by technology

[0004] The results obtained by using laser multi-line radar to scan height and width are more accurate and time-sensitive, but laser multi-line radar is expensive and consumes a lot of energy. At the same time, it must be used with high-precision digital maps. The system is relatively complicated. The background data processing capability is high

Abstract

The invention provides a special vehicle height limit measuring method. The method comprises the following steps of 1, acquiring single-point laser radar measurement data arranged in front of vehicle-mounted equipment at the top of a vehicle body, 2, analyzing and processing the acquired measurement data to determine the minimum height value between the barrier and the vehicle roof, and 3, comparing the minimum height value between the barrier and the vehicle roof with the height of the vehicle-mounted equipment, and judging whether the vehicle can normally pass through the obstacle or not. According to the special vehicle height limit measuring method, the single-point distance measurement laser radar is used for measuring the distance to perform height limit measurement, the maximum height limit of the vehicle on a running road is dynamically measured, and the running safety and normal running of the special vehicle are ensured.

Description

technical field [0001] The invention relates to the technical field of height limit measurement, in particular to a height limit measurement method for special vehicles. Background technique [0002] Due to work needs, special vehicles usually install part of the equipment (cloud platform, antenna, etc.) on the top, which leads to the overall height of the vehicle. Culverts, etc.), scratches and bumps are likely to occur, causing damage to vehicle equipment, which in turn affects the application of vehicle functions. [0003] The existing method is to use multi-line laser radar to perform high-frequency scanning measurement imaging on the front of the vehicle, analyze and measure the image combined with high-precision digital maps, obtain the height of each object in front of the scanned and photographed, and then complete the analysis and judgment. [0004] The results obtained by using laser multi-line radar to scan height and width are more accurate and time-sensitive, b...
