摘要： The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.

摘要： A rangefinder according to the present invention includes light source section, camera section, distance-measuring sensor, exposure controller and shutter. The light source section projects light onto an object for 3D imaging purposes. The camera section receives the light that was emitted from the light source section and then reflected from the object. The distance-measuring sensor estimates an approximate distance to the object. Based on the approximate distance, the exposure controller controls the optical output power of the light source section and/or the open/closed states of the shutter. The rangefinder can control the intensity of the projected light even if the object is on the move. As a result, the rangefinder can obtain highly precise information about the 3D location of the object.
