Abstract

The invention discloses a container damage detection method and system. The method comprises the following steps that: the target image and point cloud data of a to-be-detected plate are obtained, pixel point coordinates in the target image are in one-to-one correspondence with the point coordinates of the point cloud data; the depth map of the to-be-detected plate is obtained based on the point cloud data; the target image and the depth map are inputted into a trained neural network model, and the edge coordinates of a damaged area are outputted; based on the edge coordinates of the damaged area, a target image where the damaged area is marked is obtained; and based on the target image where the damaged area is marked and the point cloud data, the quantitative data of damage in the to-be-tested plate is obtained. With the method adopted, the accuracy of damage identification and positioning can be improved. Based on accurate damage positioning, the point cloud data can reflect the depth condition of the surface of the to-be-detected plate, so that the quantitative data of the damage can be accurately and efficiently obtained on the basis of the accurate damage positioning.

Description

technical field [0001] The invention relates to the technical field of container detection, in particular to a container damage detection method and system. Background technique [0002] Freight containers are widely used in water, road, railway and other forms of transportation. During transportation and use, various factors will cause the container body and structure to be damaged to a certain extent. Therefore, after each transportation activity, inspecting the container body (inspection) and assessing the damage has become an important means to ensure transportation safety. [0003] At present, the main means of inspection is manual, and there is a special post of "box inspector", so the efficiency of inspection is low. In the existing technology, in order to improve the detection efficiency, there are also inspection products with the help of inspection products. For example, the "inspection treasure" currently on the market relies on mobile devices to collect contain...
