Summary:The invention discloses a detection method for similar units based on a profile zone image. The detection method comprises the following steps of: firstly, calibrating one of the similar units of a image to be detected by utilizing a simple stroke and calibrating a background area of the detected image; secondly, dividing the calibrated image to be detected, extracting a sample of the similar units, removing the background area of the image to be detected, and reserving a foreground area consisting of the similar units; thirdly, obtaining a profile image from the foreground area, and obtaining latent object profile boundary in the image; fourthly, establishing a profile zone image in the range of adjacent area of profile points in the profile image; and fifthly, matching the sample of the similar units with the profile zone image, and determining the position of the similar units in the detected image. By adopting the invention, the similar units in the image can be searched and positioned according to simple
