Fish egg counting device and method based on image recognition

The invention discloses a roe counting device and method based on image recognition, and the device comprises a black box which is used for isolating external light, a shooting platform which is disposed at the bottom of the black box and is used for placing roes, a diffuse reflection light source which is disposed at the top of the black box and is used for illuminating the roes, and a camera which is used for collecting the images of the roes in the shooting platform. And the computer is in communication connection with the camera and is used for storing and displaying the fish egg image and carrying out identification and counting. According to the method, the contour of a target roe is extracted by performing preprocessing and morphological processing on an image according to roe characteristics, then roes of non-overlapping parts are counted through a connected domain algorithm, overlapping parts are identified and distinguished by using an SVM, and an overlapping model is established for counting. 本发明公开
