Abstract

The invention relates to the technical field of fishery informatization, and discloses a culture fish image enhancing device and method. The method comprises the following steps that a control processor receives an original image shot by a near infrared camera, and calculates the gray value of the original image; the original image is subjected to primary enhancement according to the gray value of the original image; the influence of the illumination nonuniformity and the change is eliminated; the gray value of a reflecting image is obtained; the gray value of the reflecting image is subjected to non-linear conversion to obtain a final enhancing image. The culture fish image enhancing method provided by the invention has the advantages that the image contrast is improved; the accurate continuous and consistent division basis is provided for the substance image processing.

Description

technical field [0001] The invention relates to the technical field of fishery informatization, in particular to an image enhancement device and method for farmed fish. Background technique [0002] In recent years, computer vision technology has been a hot research field in recirculating aquaculture. Since the light on the recirculating aquaculture site is generally dark, the near-infrared image obtained based on near-infrared vision is not affected by the intensity of visible light. Compared with ordinary machine vision, it is very suitable for the process of recirculating aquaculture. However, in short, the near-infrared images collected are generally dark under a relatively insufficient light condition. In addition, some fish change their body color with the environment, which will inevitably cause the overall image to be dark and the contrast is low. Object recognition brings great difficulties, so it needs to be enhanced to improve image quality. [0003] Commonly us...
