Abstract: A transport vehicle capable of detecting the position of a surrounding object without detecting the shape itself is provided. The transport vehicle includes a point group acquisition unit and an edge specifying unit. The point group acquisition unit acquires a point group PG by horizontally irradiating cargo loaded on a cargo loading unit and an object around the transport vehicle with light. The edge specifying unit analyzes the acquired point group PG using a frequency distribution with distances in left-right and front-rear directions as axes, and specifies sections S1, S2, S3, and S4 with frequencies, adjacent to an area with substantially no frequency, as positions of edges in the left-right direction or the front-rear direction of the cargo and the object around.

Abstract: A transport vehicle is provided, which is capable of adjusting a cargo loading position afterward even if a mobile shelf, a truck, or the like deviates from a predetermined position. The transport vehicle 1 includes: forks 16; a point group acquisition unit 22 that acquires a point group PG by horizontally irradiating a laser; and a distance specifying unit that specifies a distance in a left-right direction between the cargo loaded on the forks 16 and an object adjacent to a cargo loading position based on the acquired point group PG. The point group acquisition unit 22 is arranged at a position to be capable of irradiating the cargo loaded on the forks 16 and the cargo loading position with a laser.

Abstract: A transport vehicle capable of side-shifting a cargo loading unit while referring to the positional relationship of cargo with respect to the cargo loading unit is provided. The transport vehicle 1 includes: forks 16; a side shift unit 19 that side-shifts the forks 16; a point group acquisition unit 22 that acquires a point group by horizontally irradiating cargo loaded on the forks 16 with a laser; an edge specifying unit that specifies a position of an edge of the cargo based on the acquired point group; a cargo position specifying unit; and a side shift controller that controls a side shift amount of the side shift unit 19. The cargo position specifying unit detects whether the positional relationship of the cargo with respect to the forks 16 changes based on the specified position of the edge of the cargo when the forks 16 are side-shifted.
