Deep sea luminescent plankton detection method

The invention discloses a deep sea luminescent plankton detection method. The method comprises the following steps of acquiring multiple luminescent targets in a current frame foreground image; extracting the characteristic quantity of each luminescent target; for each luminescent target in the current frame foreground image, searching whether there are the luminescent targets with the same characteristic quantity in the foreground image of a previous frame; giving a new label value to the luminescent target in the current frame foreground image whose the characteristic quantity is different from the characteristic quantity in the foreground image of the previous frame; calculating the moving distance between the luminescent targets with the same characteristic quantity in the current frame foreground image and the foreground image of the previous frame; giving the new label value to the luminescent target located in the current frame foreground image of the luminescent targets havingthe same characteristic q
