Algae population detection method and device, electronic equipment and storage medium

The embodiment of the invention provides an algae population detection method and device, electronic equipment and a storage medium, and belongs to the technical field of data processing. Comprising the steps of obtaining a to-be-detected image, detecting the to-be-detected image according to a preliminary detection model, outputting a preliminary detection result, performing position correction on the preliminary detection result to obtain a corrected detection result, and segmenting corrected group frame information into a first grid matrix and a second grid matrix; and obtaining a first frame information set of a corrected individual and a second frame information set of the corrected individual, respectively projecting the first grid matrix and the second grid matrix, and filling and taking an intersection of obtained projection data to obtain a final detection result. According to the embodiment of the invention, the method for screening by using the projection grid is provided, the detection precision i
