1. A fishery monitoring management method comprises the steps of using a fishery monitoring management system to send emergency rescue instructions and pertinently processed images to a server in a nearby pond monitoring room through a WIFI wireless communication link when fish body regions outside a water surface region exist in the pertinently processed images so as to improve the efficiency and speed of pond rescue, wherein the fishery monitoring management system comprises:

  • the water surface detection equipment is connected with the normalization processing equipment and used for extracting a water surface area in the field output image based on the water surface imaging characteristics;

    the fish body identification device is connected with the normalization processing device and used for extracting one or more fish body areas in the field output image based on the fish body imaging characteristics;

    the range analysis equipment is respectively connected with the water surface detection equipment and the fish body identification equipment and is used for sending an emergency rescue instruction when a fish body region outside the water surface region exists in the field output image, otherwise, sending a normal instruction of the fish pond;

    the WIFI communication interface is connected with the range analysis equipment and used for sending the emergency rescue instruction and the field output image to a server in a nearby fishpond guardian room when the emergency rescue instruction is received;

    the day and night acquisition equipment is arranged on the cross bar above the fishpond and used for acquiring image data of a scene below the fishpond to obtain and output a scene image below the fishpond;

    the object detection equipment is connected with the day and night acquisition equipment and used for receiving the lower scene image, identifying the number of each type of object in various types of objects in the lower scene image and accumulating the number of each type of object to obtain the total number of the objects in the lower scene image;

    the area analyzing device is connected with the object detecting device and is used for analyzing the area percentage of each object in the lower scene image occupying the lower scene image so as to output the area percentages of the objects in the lower scene image occupying the lower scene image;

    the signal extraction equipment is connected with the object detection equipment and used for receiving the total number of the objects and each area percentage of each object occupying the lower scene image and sending an object complex instruction when the proportion of the number of the objects occupying the lower scene image, the area percentage of which exceeds a preset percentage threshold value, occupying the total number of the objects exceeds a preset proportion threshold value;

    the static storage device is respectively connected with the area analysis device and the signal extraction device and is used for storing the preset percentage threshold value and the preset proportion threshold value;

    the signal extraction equipment is further used for sending an object simple instruction when the proportion of the number of the objects occupying the lower scene image with the area percentage exceeding a preset percentage threshold value to the total number of the objects does not exceed the preset proportion threshold value;

    the connection control equipment is connected with the signal extraction equipment and used for recovering the power connection of the dynamic range lifting equipment when receiving the object complex instruction;

    the connection control device is used for cutting off the power connection to the dynamic range improving device when the received object simple instruction is received;

    the dynamic range improving device is used for receiving the lower scene image and executing dynamic range improving processing on the lower scene image to obtain a dynamic range improving image;

    the geometric correction device is connected with the dynamic range improving device and used for receiving the dynamic range improving image and executing geometric correction processing on a saturation component sub-image formed by each saturation component of each pixel point in the dynamic range improving image to obtain a geometric correction image;

    the malformation correction device is connected with the dynamic range improving device and used for receiving the dynamic range improving image, performing malformation correction processing on the luminance component subimages formed by the luminance components of the pixel points in the dynamic range improving image to obtain a first corrected image, and performing malformation correction processing on the hue component subimages formed by the hue components of the pixel points in the dynamic range improving image to obtain a second corrected image;

    a merging processing device, connected to the geometry correcting device and the deformity correcting device, respectively, for merging the geometry corrected image, the first corrected image, and the second corrected image to obtain corresponding corrected images, and outputting the corrected images;

    and the normalization processing device is connected with the merging processing device and is used for performing normalization processing on the corrected images to obtain and output corresponding field output images.
