PROBLEM TO BE SOLVED: To provide an object risk identification method and device.SOLUTION: The method of the invention comprises: based on an image imaged by a stereo camera, creating a heterogeneous point cloud of an object in the image, in which respective points in the heterogeneous point cloud have depth information and planar image information; based on the depth information and the planar image information of each point in the heterogeneous point cloud, determining a three-dimensional shape of the object corresponding to the heterogeneous point cloud, then generating a first risk parameter, based on the three-dimensional shape; based on the depth information and planar image information of each point in the heterogeneous point cloud, determining a surface feature of the object corresponding to the heterogeneous point cloud, then generating a second risk parameter based on the surface feature; and, based on the first risk parameter and the second risk parameter, generating a comprehensive risk parameter of the object corresponding to the heterogeneous point cloud.SELECTED DRAWING: Figure 1 |
