Embodiment Construction
[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0036] The fish body detection method of fusion background information and color feature that the present invention proposes is as follows: figure 1 As shown, the following is divided into six parts to introduce specific implementation methods.
[0037] (1) Acquisition of background
[0038] After the camera is fixed, the image taken when there is no fish target is input into the computer as the background image.
[0039] (2) Background subtraction method
[0040]Take the image of the fish target, and use the formula (1) to make the difference with the background image to obtain the preliminary detection image of the fish target. Because the background subtraction method has a small amount of calculation and a short calculation time, the preliminary detection image of the target can be quickly obtained, but at this tim...
