US Patent 11328442 Object detection system using TOF sensor

The object detection system includes a TOF sensor which outputs an image of a target space on the basis of a phase difference between reference light emitted toward the target space and reflected light from the target space, an object detection section which detects a position of an object present in the target space on the basis of the output image, an imaging conditions calculation section which calculates imaging conditions including at least one of an integration time and a light emission period of the TOF sensor on the basis of an image of the detected object, and an imaging conditions changing section which changes a configuration of the TOF sensor to the calculated imaging conditions, and the object detection section detects a position of the object on the basis of the image output under the changed imaging conditions.
