THREE-DIMENSIONAL DISTANCE MEASUREMENT APPARATUS

The present invention provides a three-dimensional distance measuring device. According to the present invention, in a three-dimensional distance measuring device using the TOF method, It is possibleto appropriately set the range of the illumination light and the amount of light according to the condition of a subject, and to suppress the deterioration of the accuracy of the distance measurement.The three-dimensional distance measurement apparatus include: a plurality of light sources 11 that irradiate light onto the subject; a light emission control unit 12 that controls light emission froma plurality of light sources; a light-receiving unit 13 that detects reflection light from the subject; a distance-calculating unit 14 that calculates a distance to the subject on the basis of a transmission time of reflection light; and an image processing unit 15 that creates a distance image of the subject on the basis of calculated distance data. The plurality of irradiation areas 3 onto which light from the light sour
