Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An object annotation method, comprising:
obtaining a reference image of an environment space, the reference image comprising at least one reference object;
obtaining target point cloud data by scanning the environment space with a three-dimensional space sensor, the target point cloud data indicating a three-dimensional space region occupied by a target object in the environment space;
determining a target reference object corresponding to the target object from the reference image;
classifying, based on the target point cloud data, the target reference object into a corresponding classification category, to obtain an object information of the target reference object, wherein the object information includes the classification category of the target reference object;
obtaining a standard size value set for the classification category of the target reference object;
determining, according to the standard size value, a projection size of the three-dimensional space region corresponding to the target point cloud data and the three-dimensional space region being projected onto the reference image; and
performing three-dimensional annotation on the target reference object in the reference image according to the determined projection size.
