Abstract: Provided is an object detection device capable of controlling to stop operation of a sensor that detects an object shape when operation of this sensor is not needed. An object detection device (1) includes a feature extraction unit (2) and a sensor activation unit (4). When an object passes an irradiation area of irradiation light from a first sensor configured to detect a feature of a part of a surface of an object by applying irradiation light, the feature extraction unit (2) extracts a feature of the object in the irradiation area. The sensor activation unit (4) activates a second sensor configured to detect an object shape when variation of the extracted feature falls below a predetermined first threshold.

Abstract: A distance measurement apparatus comprises a distance measurement optical signal generation part, a collimating part, a beam diameter change part, an emission direction control part, and a beam diameter change control part. The distance measurement optical signal generation part generates an optical signal for measuring the distance to a target. The collimating part collimates the optical signal. The beam diameter change part is able to change a beam diameter of the collimated light. The emission direction control part controls an emission destination of the collimated light with the diameter changed. The beam diameter change control part controls the changing of the beam diameter by the beam diameter change part according to the emission direction of an outgoing.
