Measurement range expansion of a range image sensor using a multi-slit laser projector

This paper proposes a method for expanding the measurement range of a range image sensor using a multi-slit laser projector. In the conventional method, the measurement range is 360-800 mm. In order to extend the measurement range, it is necessary to solve the correspondence problem. The measurement range is expanded using blur when the camera is not in focus. The effectiveness of the proposed sensor is verified through distance measurement experiments.
