<p>A three-directional laser ranging device is applied to measure a box (5). The box (5) is placed against a working area. The three-directional laser ranging device includes: a body (1), a laser device (2) having three sets of sending assemblies (21, 22, 23) and being disposed inside the body (1), each sending assembly (21, 22, 23) being able to emit a light beam in the sensing direction thereof, to receive the light beam after the light beam contacts the working area and is reflected, and to produce a distance signal; a microprocessor (3) connected to the laser device (2) receiving each distance signal and performing a calculation to obtain the volume and material volume of the box (5) according to each distance signal successively; and a display screen (41) connected to the microprocessor (3) being used by the microprocessor (3) to control the volume and material volume of the box (5).</p> |
