Problems solved by technology
[0002] In many occasions, it is necessary to observe the details of high-speed moving targets. Due to the high-speed moving targets' flying speed (typically 1000 m / s), the distance to be observed is large, so a single high-speed camera cannot be used for effective shooting. Field of view and detailed observation is a contradiction
In order to solve this problem, the common method is to place a certain number of sky screen targets under the motion track to cooperate with the rotating mirror to shoot. The sky screen target is a discrete point on the motion track. To improve the tracking accuracy can only increase the number of sky screen targets. not feasible in practice

The invention provides a high-speed moving target camera system based on laser ranging. The high-speed moving target camera system comprises a laser range finder and a high-speed moving target camerasystem body. The laser range finder is used for measuring the distance of a moving object, and the high-speed moving target camera system comprises a servo controller, a servo motor, a rotating mirrorand a high-speed camera. The servo controller is connected with the laser range finder and used for collecting the distance of a moving object, and the servo controller is connected with the rotatingmirror through the servo motor and used for adjusting the angle of the rotating mirror. And the servo controller is also connected with the high-speed camera and is used for triggering the camera toshoot. The system is simple in structure and convenient to install and use, and can effectively improve the tracking precision.
Description
technical field [0001] The invention relates to the field of image acquisition, in particular to a high-speed moving object camera system based on laser ranging. Background technique [0002] In many occasions, it is necessary to observe the details of high-speed moving targets. Due to the high-speed moving targets' flying speed (typically 1000 m / s), the distance to be observed is large, so a single high-speed camera cannot be used for effective shooting. Field of view and detailed observation It is a pair of contradictions. In order to solve this problem, the common method is to place a certain number of sky screen targets under the motion track to cooperate with the rotating mirror to shoot. The sky screen target is a discrete point on the motion track. To improve the tracking accuracy can only increase the number of sky screen targets. Not feasible in actual operation. Contents of the invention [0003] The purpose of the present invention is to solve the above proble...
