According to information from Tianyancha, Hunan VisionBit Robot Co., Ltd. has been granted a patent titled 'A Workpiece Positioning Method and Positioning System Based on Multi-view Vision'. The patent, bearing the authorization announcement number CN119779139B, was officially authorized on October 14, 2025, with the application submitted on November 4, 2024.

This innovative patent facilitates collaborative work among multiple cameras in two distinct stages: rough positioning and precise positioning. Initially, a primary camera undertakes rough positioning of the workpiece. Subsequently, several auxiliary cameras capture secondary images from various angles. By integrating these images with a pre-established 3D model library, the system accurately calculates the spatial orientation of the workpiece. This approach effectively addresses the challenge of achieving precise workpiece positioning within a large field of view, thereby enhancing production efficiency and minimizing product scrap rates.
