The invention provides a curb boundary detection method and device based on parallel structured light and an engineering machine. The method comprises the following steps of receiving an irradiation curb of two beams of parallel structured light, obtaining a curb image, extracting three-dimensional structure information of the curb, and calculating the distance between the engineering machine and the curb through the obtained curb structural information. By means of the technical scheme, by the adoption of the irradiation curb of the parallel structured light, the three-dimensional structure information of the curb is obtained by the collected curb image, and therefore the distance between the engineering machine and the curb is calculated. By means of the method, the accurate distance between the engineering machine and the boundary of the curb is visually obtained, detection errors are avoided, and the detection accuracy is improved.
Description
Technical field [0001] The invention relates to the technical field of construction machinery, and in particular to a curb boundary detection method and device based on parallel structured light, and construction machinery. Background technique [0002] During construction, construction machinery needs to keep driving along the curb. The current detection methods for curb boundaries include: (1) Manual observation: The current mobile vehicles and equipment mainly observe the curb edge manually to estimate the position of the curb boundary and the relationship with the vehicle. The distance between. (2) Camera monitoring: A camera is installed on the left side of the vehicle body to transmit the picture to the display screen in real time for the operator to observe and judge. (3) Image processing scheme: Collect the road curb image through the camera, and use the structure information of the curb to locate the curb boundary and measure the distance. [0003] The disadvantages of t...
