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.

Description

technical field [0001] The invention relates to the technical field of photoelectric imaging, in particular to a flash tracking imaging method for acquiring target motion parameters. Background technique [0002] It is of great significance to study the effective imaging of dynamic targets in complex backgrounds and the rapid acquisition of motion parameters for target tracking, autonomous navigation and security. The traditional techniques for obtaining motion parameters of dynamic targets mainly include high-speed photography and dual image sensing intersection measurement, photoelectric theodolite, synthetic aperture radar and synthetic aperture laser radar, etc. [0003] 1), high-speed photography and dual image sensor intersection measurement [0004] In the traditional low-altitude target position parameter measurement system, if the target is flying on a certain route, it is necessary to set a calibration object at the corresponding position, and then use two sets of...
