In a laser rangefinder (100) according to the present invention, an optical device (101) projects a scanning grid pattern (60) onto an object by irradiating laser light onto the object, a camera unit (40) photographs the projected image at that time as a photographed scanning grid pattern (70), and a measurement unit (53) measures the distance to the object on the basis of the distance between the lines represented by the photographed scanning grid pattern (70). As a result, even if the rangefinder is mounted onto a small robot, a vehicle, or the like, the distance from the rangefinder to an object can be easily measured. |
