  • Patent number: 11315264
    Abstract: The present disclosure provides a laser sensor-based map generation method. In an embodiment, the method includes: obtaining image data, the image data being acquired by a visual sensor; determining first point cloud data belonging to glass-like region in laser data based on the image data; adjusting a weight of the laser data according to the first point cloud data; fusing the first point cloud data and second point cloud data belonging to non-glass-like region in the laser data based on the adjusted weight of the laser data, to generate a map.

  • Publication number: 20210304411
    Abstract: This application provides a positioning method and apparatus, a storage medium and an electronic device. The method includes: determining a first spatial coordinate of an image capturing apparatus when the image capturing apparatus captures a depth image in a target space and determining attitude information of the image capturing apparatus when the image capturing apparatus captures the depth image; performing region segmentation on the depth image, to obtain at least one sub-region; determining a positioning sub-region in the at least one sub-region; determining a second spatial coordinate of the positioning sub-region in the target space based on distance information recorded in the depth image, the first spatial coordinate, and the attitude information; and constructing a map based on the second spatial coordinate.
