Abstract

The present invention provides a dynamic 3D real-time modeling method based on the improved particle swarm optimization algorithm, which includes the following steps: Step S0: providing a decoration preview system, which includes a scanning module, a recording module, a calculation module, an import model module, a mapping module and Display module; step S1: the scanning module cooperates with the recording module to complete the calibration of the space vector information of the 8 corners of the room to be simulated, record the gyroscope parameters and calculate the space vector data as output parameters; step S2: the calculation module The core calls the intelligent algorithm, accepts the output parameters of step S1, and calculates the room with the same proportion as the cubic room and the user's height unit length data as output parameters; step S3: calls the 3D engine by the imported model module, accepts the output parameters of step S2, Dynamically create a 3D model of the room. The improved particle swarm algorithm of the invention increases the diversity of particles to control the convergence speed and improve the search precision.

Description

technical field [0001] The invention relates to a dynamic 3D real-time modeling method based on an improved particle swarm algorithm. Background technique [0002] At present, some research results have been obtained on the 3D modeling method: the more popular 3D modeling method abroad is the 3D laser scanning point cloud modeling method. Bahman Jafari et al. have shown that this modeling method can achieve extremely high model accuracy. The display of details is also very strong, but this method has high requirements on hardware, and only high-performance computers can handle and complete the 3D modeling task. Reem S et al. proposed a 3D modeling method for matting images from 2D images. This 3D modeling belongs to the 3D reconstruction technology, and the modeling speed is high and the efficiency is high, but the accuracy is low. Zhang Wei and others proposed a 3D modeling method called surface modeling, but the application range of this method is small, and the technical...
