High-speed moving object detecting and speed measuring method and system based on double-linear-array cameras

The invention relates to the technical field of image processing, and provides a high-speed moving object detecting and speed measuring method and system based on double-linear-array cameras. The system comprises a preprocessing module used for pre-calibrating parameters, the double-linear-array cameras used for obtaining two images respectively, a movement detecting module used for detecting a moving object in the images, a matching operation module used for carrying out the matching operation on the left image and the right image, an extraction module used for obtaining movement pixel track points and the pixel difference of the two images, a first calculation module used for calculating the time difference when the moving object passes through the two cameras and calculating the movement direction angle of the object, and a second calculation module used for calculating the movement speed of the object. According to the detecting system based on the double-linear-array cameras, the matching calculation is carried out according to the two images, the movement speed of the object is worked out, the high-speed moving object can be detected in real time, the movement speed of the object can be worked out in real time, and the movement track direction can be judged.
