In order to improve the remanufacturing efficiency of waste mechanical parts and components and monitor the failure status of waste mechanical parts in real time,we propose a low-cost and high-efficiency three-dimensional color model reconstruction method for waste mechanical parts.After data preprocessing,pose estimation and surface geometry reconstruction,the texture mapping algorithm is used to jointly optimize the camera pose and image quality,and the subjective and objective evaluation systems and comprehensive evaluation parameters are proposed,and finally the three-dimensional color model of waste mechanical parts is obtained.Experiments show that the reconstruction method proposed in this paper has small errors,clear details,and can obtain the best parameter setting scheme,which has guiding significance for the actual production process.
