The utility model discloses a measurement system of scattered spot of laser image based on people's eye characteristic, including being used for the laser image camera lens on the photosensitive element that forms images, a photosensitive element for inciting somebody to action the laser image that the camera lens acquireed forms images, a data processor for being based on formation of image image data calculates the data that are signified the scattered spot characteristic of laser image, the effective aperture of camera lens is the size in people's pupil hole, the focus behaviour eye focus of camera lens, the approximate people's eye retina cell size of pixel size of photosensitive element, the light intensity response curve approximate match people eye of photosensitive element is to the curve of the intensity impression of light intensity. Technical scheme is more accurate to the measurement of the scattered spot of laser image, and need not increase equipment cost.
