Product Manufacturing Information Transmission Method Based on Augmented Reality

To address the problem of low efficiency in product quality checking by using the 2D drawing or 3D model, a product manufacturing information transmission method based on augmented reality is proposed. First, 3D model product manufacturing information is extracted based on manufacturing features.Then, the multi-view template image set of the inspecting 3D CAD model is generated in the offline stage and the correlation between the template image and the manufacturing feature is established. Finally, according to the real-time images obtained by the camera, the matching relationship between the real-time images and the template images is established, and the camera pose is initialized according to the correlation information of the matching template images. The product manufacturing information is augmented onto the manufacturing site image by using this initial pose. The results of the experiments show that the method can effectively transfer the product manufacturing information in the manufacturing site, improve the efficiency of product quality inspecting, and lighten the burden of staffs.
