container transaction monitoring method based on an LSD linear detection segmentation algorithm

Abstract

The invention discloses a container transaction monitoring method based on an LSD straight line detection segmentation algorithm. The method comprises the steps of A, generating a standard template; B, carrying out comparison statistics on new video frame straight line elements; and C, carrying out result disposal. According to the method, an LSD algorithm is used for extracting image straight lines, the initial position and state of the container are obtained through videos collected by a camera, and if the container moves abnormally, the container moving abnormally is found out through comparison with the initial position, and an abnormal movement event is output. According to the invention, by establishing the multi-frame template, the influence of camera jitter is effectively reduced;And a standard template is further established, a sensitive area is defined, the report mode of transaction is effectively improved, multi-thread division is carried out, and the processing efficiencyis improved.

Description

technical field [0001] The invention relates to the technical field of container monitoring, in particular to a container abnormality monitoring method based on an LSD line detection and segmentation algorithm. Background technique [0002] The container is fixed by fixing devices such as lock buttons and lashing rods, and placed according to the stacking principle of bottom heavy and top light to enhance the stability of the container. If the stability of the container is low, the rolling period becomes longer, and the ability to resist cross wind and waves is weak. Once the container moves and the center of gravity of the ship is unstable, the danger of navigation will increase and accidents will easily occur. [0003] In the past, it was common in the industry to install cameras on ships to monitor container changes. However, this method can only observe large-scale changes. If there is a slight change, it is difficult for the camera to observe, and container changes cann...

If the stability of the container is low, the rolling period becomes longer, and the ability to resist cross winds and waves is weak. Once the container moves and the center of gravity of the ship is unstable, the danger of navigation will increase and accidents will easily occur.

[0003] In the past, it was common in the industry to install cameras on ships to monitor container changes. However, this method can only observe large-scale changes. If there is a slight change, it is difficult for the camera to observe, and container changes cannot be avoided. happened
