Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0030] In order to meet the follow-up high-precision automatic identification requirements and facilitate the visual inspection of data results by production operators, the embodiment of the present application provides a laser point cloud data preprocessing method, which is often applied to road pseudo-spotting based on laser radar data Generation of color orthographic images. Specifically, the complex three-dimensional recognition and interaction problems based on lidar data are converted into two-dimensional data processing problems. During the implementation of the present invention, the trajectory information of the three-dimensional laser point cloud collected by the acquisition vehicle is introduced, and the preset height range ...
