Abstract
This invention discloses a three-dimensional imaging radar system and method based on a plurality of times of integral. The system includes 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 the light pulse trains illuminate an object, the object reflects the light in succession. The reflected light is sensed by the image sensor through the optical band-pass filter, 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 data processor analyzes the three images to obtain contour information and distance information about the object. Finally, the display terminal displays results.
