The invention discloses a fruit grading system and a method based on DSP machine vision. The system comprises a DSP machine vision system, a man-machine interactive system, a conveying module, a grading trigger module and the like. The method comprises the following steps: a camera acquires fruit images to a DSP video processing system, and the DSP video processing system identifies the external feature information of the fruit; the fruit information is supplied to grading software installed in an industrial personal computer through a PCI interface; and the grading software distinguishes the grade of the current fruit according to the fruit information and the fruit grade information preset by the user through a man-machine interactive module, and finally transmits a triggering signal to an actuating mechanism to carry out grading. The image acquisition and image processing tasks are executed by the special DSP high-speed image processing system, the DSP system adopts the fruit grading method of the inventio
