Abstract

It is a challenge for conventional projectors to conduct projection mapping for a 3D dynamic moving object along the depth direction, due to the limitation of their narrow depth-of-field. Here, a dynamic projection system is proposed that has overcome the above limitation by employing a liquid-filled variable focal unit and a depth-sensing module. The depth sensor detected the depth information of the projection target, and then served as feedback to adjust the focal length of the variable focal lens, in turn, the focal length of the projection system would be controlled. A well-focused projection mapping with a randomly moving object would be demonstrated.
