The PCA series 3D camera group uses MEMS-encoded grating structured light for scanning, and reconstructs the real three-dimensional point cloud data of the object according to the image restoration algorithm. Meet the needs of industrial-grade high-resolution, sub-millimeter 3D vision applications. The equipment has small size, large depth of field, high measurement accuracy, low cost and simple operation. It can be applied to scenarios such as biometrics, industrial automation, robotics, and 3D object reconstruction.
