Problems solved by technology

The existing system generally eliminates the blurring of the image by reducing the moving speed of the carrier, so the efficiency of the system is greatly reduced
Another method is the method of image processing, called intra-frame image stabilization, using methods such as Wiener filtering or inverse filtering to restore the blurred image formed by line motion, but the degree of restoration of this method is extremely limited, and the processing speed Very slow, unable to meet real-time requirements

Embodiment Construction

[0021] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0022] The image stabilization method of the TV camera system on the motion carrier based on the optokinetic reflex is to use the mathematical model of the human eye optokinetic reflex control system, so that when the motion carrier moves, the camera produces a movement similar to the eyeball to obtain a stable image; the operation steps are as follows :

[0023] (1) Using sensors to measure the movement speed parameters of the moving carrier itself;

[0024] (2) A / D conversion: the continuous analog signal obtained by the sensor is converted by A / D to obtain a digital signal;

[0025] (3) Digital filtering: smoothing the obtained digital signal, enhancing the effective signal, eliminating or reducing noise;

[0026] (4) Scale conversion: perform sensor calibration, and convert the electric quantity value measured by the sensor into the value o...

Abstract

The related moving-carrier TV pickup system image stabilization method based on optokinetic reflex comprises: with people eye optokinetic reflex control system model, let the camera move similar to people eye reflex motion when the carried moves fast; exactly, detecting motion parameter, taking AD conversion, digital filtering, and transforming scaling; driving console motor rotating. This invention can improve image quality conveniently.

Description

technical field [0001] The invention relates to a method for stabilizing images of a television camera system on a moving carrier, in particular to a method for stabilizing images by controlling the motion of a camera on a moving carrier by using a human eye optomotion reflection method. Background technique [0002] The TV camera system has been widely used in the patrol equipment of ships, the reconnaissance system of unmanned aerial vehicles and the surveillance system of reconnaissance vehicles and other fields. In order to accurately search, aim, observe or measure a specific target, it is necessary to ensure that the images captured by the camera are clearly visible, but the working effect of the TV camera system is affected by the movement of the carrier. When the carrier moves quickly, the image from the camera becomes blurred. And this blurred image will cause fatigue to the observer, resulting in misjudgment and missed judgment, or even no judgment at all; for the...
