Abstract
Abstract: Aiming at the problems of mesh visual feature loss and oversimplification in mesh simplification algorithm, a visual feature preservation based triangle mesh model simplification algorithm is proposed. The multi-viewpoint perception method is used to measure the visual perception error caused by the difference between the original and the simplified model in the two-dimensional view under the optimal viewpoint set. Based on QEM algorithm, a novel geometric error metric is built by introducing the triangle shape factor. The triangle collapse error function is defined by combining visual perception and geometric error to control the simplified depth of the model. Through new vertex position optimization and error update, the mesh model simplification ofvisual feature preservation is achieved. The experimental results show that the proposed algorithm outperforms the traditional method in simplifying visual quality and geometric quality, and can better maintain the visual and geometric feature information of the model.
