Flash tracking imaging method for acquiring movement parameter of moving target

Abstract

The invention discloses a flash tracking imaging method for acquiring movement parameters of a moving target. The method utilizes a pulse laser as an illuminated light source and a CCD (Charge Coupled Device) provided with a strobing gate as an imaging device based on a range gating imaging technology and realizes the imaging of a movement trail of the moving target through the working mode of a time delay integral. By adopting the range gating, the range information of the target can be acquired, and the target can be extracted from a complex background, thereby reducing the complexity of post-treatment; and by adopting the time delay integral, the movement trail of the target can be directly acquired. The movement parameters of the target can be inverted through establishing a corresponding relation between a three-dimensional space and a bidimensional image plane of an interested zone of observation, wherein the movement parameters mainly comprise the space position, the speed and the acceleration of the target. The invention has favorable working environment adaptability, can directly acquire the 3D movement trail of the target and realize the non-contact measurement of the movement parameter of the target.
