Embodiment

[0057] A method for identifying illegal phishing behaviors based on automatic image recognition, comprising the following specific steps:

[0058] Step 1, real-time extraction of video image sequences from cameras installed in prohibited fishing areas.

[0059] 1.1 The camera used in the present invention is a common monitoring camera or a high-definition camera for smart phones, and obtains the monitoring image of RGB (Red, Green, Blue) color space from the real-time video recorded by the camera;

[0060] 1.2 Compress the monitoring image size obtained in 1.1 to the standard 640*320 image size through an image interpolation algorithm.

[0061] Step 2, establish the edge extraction model of the fishing rod, and use the edge extraction operator to extract image edge pixels from the input video image sequence. The specific implementation method is as follows:

[0062] 2.1 The fishing rod edge extraction model referred to in the present invention means that the fishing rod has a...

Abstract

The invention discloses an illegal fishing behavior identification method based on automatic image identification. The method comprises the steps that images shot by a camera are processed in real time, then whether illegal fishermen exist in a region or not is judged; if existing, a voice module is started to play warning and expelling voice recorded in advance, the illegal fishermen are warned and fish schools are scared, so that fishing behaviors of the fishermen are destroyed; meanwhile the shot monitoring pictures in which illegal fishing behaviors exist are sent to an administrator. By means of the method, automatic monitoring of a fishing prohibited area can be achieved, the high manpower cost is reduced to the utmost extent, meanwhile the management efficiency is improved, the monitoring accuracy is high, and the method has a great engineering application value.

Description

technical field [0001] The invention relates to the fields of image recognition and video surveillance, in particular to an automatic image recognition-based illegal fishing behavior recognition method. Background technique [0002] Fishing is a hobby loved by modern people. You can often see anglers fishing by rivers and lakes, but fishing is not allowed in many places for management needs and commercial interests, such as scenic lakes, private contracted res. [0003] The existing methods to prohibit fishermen from fishing in illegal areas mainly include setting warning signs and arranging management personnel to patrol, but in practice, setting warning signs cannot effectively drive away illegal fishermen, and arranging management personnel to patrol Great waste of human resources. Contents of the invention [0004] The object of the present invention is to provide a method for identifying illegal fishing behaviors based on automatic image recognition, which can autom...
