Problems solved by technology

At the same time, a tallying person can check the multi-quay bridge in real time, which greatly improves the work efficiency. However, this method still needs manual real-time checking during the detection process, and does not realize the automatic detection of damage.

Embodiment Construction

[0035] The present invention needs to build a channel suitable for container vehicles to pass through, and install 3D cameras and lasers on the top, left side, right side, front end and rear end of the channel respectively, and respectively monitor the container top, left side, right side, The front and rear container surfaces are scanned to obtain surface texture information, and sensors are installed on the left and right sides of the channel to trigger 3D cameras and laser scanning.

[0036] Such as figure 1 Shown, the realization method of the present invention is as follows:

[0037] 1. Laser Triangulation

[0038] 3D scanning is mainly that the laser shoots the laser to the surface of the measured object through the lens, and the laser reflected by the object is received by the camera. According to different distances, the camera can "see" this light spot at different angles. Based on this angle and the known distance between the laser and the camera, the distance betw...

Abstract

The invention provides container damage detection equipment based on 3D imaging. The detection equipment comprises a storage device and a processor coupled to the storage device, wherein the processor is configured for executing programs stored in the storage device and carries out operation as follows: triggering 3D cameras and lasers mounted in positions facing the top, the left side, the right side, the front end and the rear end of a container respectively to scan the top surface, the left side surface, the right side surface, the front surface and the rear surface where the 3D cameras and lasers face respectively, and obtaining surface texture distribution of the container; calibrating the 3D cameras to obtain three-dimensional information of the container; analyzing surface texture of the container, and judging whether broken holes or recesses are formed in the container surface according to the national standards.

Description

technical field [0001] The invention belongs to the technical field of port automation, and in particular relates to a container damage detection device and method based on 3D imaging. Background technique [0002] Container damage detection, as an important part of tally, means that when a ship arrives at and leaves the port, it is inspected during the loading and unloading process of the container to check whether there are holes, dents, overall deformation, etc. and worker’s disability inspection, early detection of containers with problems during transportation, reducing damage to the transported goods, ensuring safe transportation of goods, and taking remedial measures in time for damaged containers, and the port, cargo owner and carrier The responsibility of the party shall be determined in order to make corresponding compensation. [0003] The traditional container damage detection is completely done manually. The tally staff stands on the ship deck or on the shore, ...
