METHOD AND DEVICE FOR RECOGNIZING DANGEROUSNESS OF OBJECT
First Claim
1. A method of recognizing object dangerousness, comprising:
- a point cloud generation step of generating, based on an image captured by a stereo camera, a heterogeneous point cloud of an object in the image, each point in the heterogeneous point cloud having depth information and planar image information;
a first parameter generation step of determining, based on the depth information and the planar image information of each point in the heterogeneous point cloud, a solid shape of the object corresponding to the heterogeneous point cloud, and then, generating a first dangerousness parameter according to the solid shape;
a second parameter generation step of determining, based on the depth information and the planar image information of each point in the heterogeneous point cloud, a surface feature of the object corresponding to the heterogeneous point cloud, and then, generating a second dangerousness parameter according to the surface feature; and
a comprehensive parameter generation step of generating, based on the first and second dangerousness parameters, a comprehensive dangerousness parameter of the object corresponding to the heterogeneous point cloud.
