Three-dimensional imaging radar system and method based on a plurality of times of integral

A three-dimensional imaging radar system based on a plurality of times of integral, comprising:

• an LED light source (1), an optical band-pass filter (2), an image sensor (3), an electronic shutter (4), a data processor (5), and a display terminal (6), wherein the optical band-pass filter (2) and the electronic shutter (4) are fixed to the image sensor (3), the LED light source (1) and the image sensor (3) are connected with the data processor (5), the data processor (5) is connected with the display terminal (6), the LED light source (1) generates a series of light pulse trains, when these light pulse trains illuminate an object, the object reflects the light in succession, the reflected light is sensed by the image sensor (3) through the optical band-pass filter (2), to form an image on the image sensor (3), 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 data processor (5) analyzes the three images to obtain contour information and distance information of the object, the display terminal (6) finally displays results, the LED light source (1) includes one or more light pulse generators capable of generating microsecond pulses and nanosecond pulses, and the light pulse generator is an LED or laser.
