Disclosed are a three-dimensional imaging radar system and method based on a plurality of times of integral. The system comprises: an LED light source, an optical band-pass filter, an image sensor, an electronic shutter, a data processor and a display terminal. The LED light source generates a series of light pulse trains, and when these light pulse trains illuminate an object, the object will reflect the light in succession. The reflected light is sensed by the image sensor through the optical band-pass filter, so as to form an image on the image sensor. The image sensor performs exposure imaging three times in succession for the reflected light of the same pulse under the action of the electronic shutter. The contour information and the distance information about the object can be obtained through analysis of the three images by the data processor. Finally, results are displayed through the display terminal. By means of the present invention, three-dimensional radar imaging of a high speed and a high resolution in a middle or near distance can be achieved, and the cost is low. |
