With the rapid upgrading of China's intelligent manufacturing field, the demand for industrial three-dimensional scenes is also more diverse, so a number of three-dimensional measurement and detection technologies have emerged. However, as a new generation of 3D imaging technology, optical field camera has almost no substantial application in industry. Research applications focus more on the measurement of three-dimensional flow fields and flames. Yimu Technology takes the lead in applying optical field imaging technology to industrial 3D inspection, and realizes the localization and small-batch production of optical field cameras. The accuracy of optical field 3D reconstruction is at the international leading level, and it has been successfully applied in screen 3D defect layering, multi-layer transparent material defect three-dimensional layering and semiconductor gold wire defect detection.
