Abstract: A transport possibility determination device comprises a distance measurement unit and a control unit. The distance measurement unit acquires information about the distance to an object. The control unit determines the state of a load when the object is a transport platform on which the load has been placed, on the basis of the information about the distance to the object acquired by the distance measurement unit. The control unit determines whether or not a transportable condition, which is a condition for permitting a forklift to transport the load, is met on the basis of the determined state of the load.

Abstract: A conveyance system 50 includes a main body unit 31, a TOF sensor 20, and a attachment orientation sensing device 10. The TOF sensor 20 has an emission unit 21 that emits light toward a floor surface FL, an imaging element 23 that detects the light emitted from the emission unit 21, a distance information acquisition unit 11 that acquires the information about the distance to reference points P1 and P2 on the floor surface FL according to the phase difference between received light wave and an emitted light wave detected by the imaging element 23, and an angle information acquisition unit 12 that acquires information about the angle up to the reference points P1 and P2, wherein the conveyance system is attached to the main body unit 31.

Abstract: A TOF sensor 20 comprises an emission unit 21, an imaging element 23, a distance information acquisition unit 11, an angle information acquisition unit 12, and an attachment orientation sensing unit 14. The emission unit 21 irradiates the floor surface FL with light. The imaging element 23 senses the light emitted from the emission unit 21. The distance information acquisition unit 11 acquires information about the distance to reference points P1 and P2 on the floor surface FL according to the phase difference between the received light wave and the emitted light wave sensed by the imaging element 23. The angle information acquisition unit 12 acquires information about the angle to the reference points P1 and P2. The attachment orientation sensing unit 14 senses the attachment orientation with respect to the floor surface FL on the basis of the distance information and the angle information acquired by the distance information acquisition unit 11 and the angle information acquisition unit 12.
