A target colony automatic positioning and identification method

The invention discloses a method for automatically positioning and identifying a target colony, which comprises the following steps of: acquiring and storing a color image of a culture dish containingthe colony, and carrying out morphological feature acquisition pretreatment on the color image to obtain a contour binary image of the colony and the culture dish; acquiring morphological characteristics of the bacterial colony according to the contour binary image; screening out independent bacterial colonies from the bacterial colonies according to preset screening conditions; calculating to obtain the number, position information and area characteristics of the independent colonies, and identifying target colonies from the independent colonies according to preset identification conditionsand the number and area characteristics of the independent colonies; and displaying and storing the position information and the image of the target colony. By the adoption of the method, independentand adhesion bacterial colo
