Problems solved by technology

The traditional detection of ship overload is ruler measurement, manual visual inspection or the use of telescopes, etc. This detection method is time-consuming and laborious, and is not suitable for popularization
Moreover, some ship owners blindly pursue interests, and overloading is very common. At the same time, because the management department adopts the above-mentioned manual detection method, the management force is very limited due to factors such as the number of staff, so that the overloading cannot be detected in time and effectively, causing personal and property damage.

Embodiment Construction

[0038] The invention discloses a ship overload detection method based on video analysis technology, comprising the following steps:

[0039] When there is a ship approaching the wharf, the video and image information of the ship is captured by the PTZ camera installed on the shore of the wharf;

[0040] Connecting the captured video and image information to a video encoder for real-time encoding;

[0041] The video analysis server invokes the video and image information encoded by the video encoder, analyzes and processes the video and image information, and compares the security management rules and the conditions set by the user, if the security management rules and the According to the conditions set by the user, an alarm message is given;

[0042] The video and image information are decoded by the video decoder and sent to the terminal display device together with the alarm information for display.

[0043] In the above-mentioned detection method, the step of judging whe...

Abstract

The invention discloses a video analysis technique-based ship overload detection method, which comprises the following steps of: when a ship approaches a wharf, shooting video and image information of the ship by using a tripod head camera arranged on the wharf shore; accessing the shot video and image information to a video encoder to perform real-time encoding; calling the video and image information encoded by the video encoder by using a video analysis server, analyzing and processing the video and image information, and comparing the video and image information with safety management rules and user-defined conditions, if the video and image information cannot meet the safety management rules and the user-defined conditions, giving a warning message; and transmitting the video and image information decoded by a video decoder together with the warning message to a terminal display device for display. The invention also discloses a detection system for implementing the method; and by using the system to adopt the detection method, the working efficiency of maritime personnel is greatly improved, and the safety of ships is effectively guaranteed.

Description

technical field [0001] The invention relates to a ship overload detection method and system, in particular to a ship overload detection method and system based on video analysis technology. Background technique [0002] Overloading of ships is an important cause of accidents. Ship overloading means that the ship is loaded beyond the rated total load capacity, which is specifically manifested in that the prescribed load line marks are submerged in water, and the freeboard of small inland river vessels is less than the prescribed scale. The traditional ship overload detection methods are ruler measurement, manual visual inspection or the use of telescopes, etc. This detection method is time-consuming and laborious, and is not suitable for popularization. Moreover, some ship owners blindly pursue interests, and overloading is very common. At the same time, because the management department adopts the above-mentioned manual detection method, the management force is very limited...
