Ship deck cable database construction method and system

Abstract

The invention provides a ship deck cable database construction method and system, and the method comprises the steps: obtaining video data of unsafe behaviors; preprocessing the video data; screening the preprocessed data; carrying out labeling on the screened images by adopting the labmeli; and storing the basic information of the marked unsafe behavior database image in a picture data table to form a deck cable unsafe behavior database. An image database of unsafe behaviors of sailors is collected, unsafe behavior characteristics of each database picture are extracted, and the database picture characteristics and unsafe behavior indexes are stored in a picture characteristic table; and unsafe behaviors of the sailors operating the deck cable are monitored through algorithms such as deep learning and a neural network, and the sailors can obtain early warning through bracelet vibration on the basis of support of the project of a sailors unsafe behavior and state monitoring and early warning platform.

Description

technical field [0001] The present invention relates to the intersecting technical field of the ship field and the computer field, and in particular, relates to a construction method and system for a ship deck cable database. Background technique [0002] The monitoring of unsafe behavior of crew deck cables is a crucial step in the crew behavior monitoring system. With the wide application of video surveillance technology in the ship field, the unsafe behavior of crew rope operations has gradually changed from personnel and experience-led monitoring to video surveillance. Intelligent monitoring and video intelligent monitoring are also gradually recognized by the crew and supervisors on the road during ship operation. [0003] However, in the field of ships, the current research and application of video surveillance on unsafe behaviors of crew members is not extensive, and the main difficulties are as follows: [0004] 1. Object tracking management is difficult. The work ...

Problems solved by technology

[0004] 1. Object tracking management is difficult

The work of the crew is an international job. Usually, ocean-going ships have to sail around the world. It is relatively difficult to study, and it is impossible to track and manage the staff conveniently in fixed places such as mines and railway stations.

[0005] 2. Difficulty in real-time contact

The signal on the ship on the ocean cannot be kept as good as on land, so it cannot be contacted in time, and it cannot communicate in time like on the shore

[0006] 3. Since the ship itself has characteristics such as rolling and pitching that do not exist on land, it will encounter characteristics such as unstable video images during the video collection process, and the land-based data set production method cannot be fully applied

[0008] However, the unsafe behaviors in the professional data sets of mines and construction sites are more professional, and there are fewer classifications that can be used for navigation, and because the producers of the data sets lack navigation experience, they do not understand the unsafe behaviors that are prone to occur at sea , it is difficult to be practically applied in the field of navigation
