Time of flight identification system for warehousing and freight transport and identification method thereof improving the space utilization ratio of the container and cargo management efficiency and safety

Provided are a time of flight (ToF) identification system for warehousing and freight transport and an identification method thereof. An optical identification apparatus is assembled in a container; the optical identification apparatus includes a first image acquisition unit, a second image acquisition unit, a third image acquisition unit, a beam receiving and correcting unit, an estimation and operation processing unit, a transmission module, and a power supply module; in addition, the optical identification apparatus is connected to a monitoring apparatus by a signal. The time of flight identification steps and processes for a plurality of sections of space are performed inside the container by using the optical identification apparatus, so that a logistic manager or inventory personnel checks whether an accommodating space inside the container is correctly stored by the inventory personnel. Therefore, the time of flight identification system has the advantages of high space utilization of the container, ac
