The invention provides an object model construction method and device, and the method comprises the steps: firstly obtaining a reference point cloud data set and target point cloud data of a target object model, then determining target reference point cloud data according to the semantic features of the reference point cloud data in the reference point cloud data set and the semantic category of the target point cloud data, according to the target reference point cloud data and target point cloud data of a target object model, determining target pose information of the target object model in a target three-dimensional map according to the target reference point cloud data and the target point cloud data, and finally constructing the target object model in the target three-dimensional map according to the target pose information. According to the method, the target pose information of the target object model is automatically obtained in a semantic matching mode, so that the link of manually labeling the object pose is omitted, the target object model is automatically constructed in the target three-dimensional map, and the construction efficiency of the target three-dimensional map is improved.
Description
technical field [0001] The invention relates to the field of map making, in particular to a method and device for constructing an object model. Background technique [0002] The purpose of the digital twin map is to create a static virtual environment that is almost identical to the real world, and this static virtual environment is generally created by a game engine, which mainly contains different 3D models. The key to constructing a digital twin map is to combine these 3D models Import it into the game engine according to the real object pose. [0003] At present, the 3D model in the digital twin map is generally divided into "road part" and "static object part". Among them, the road part can be imported into the engine at one time through the high-precision map that has been made according to a specific format standard, while the static object part needs to obtain the attitude of these objects in advance to import in batches. However, the general way to obtain the pose...
