Embodiment

[0090] The conditions of this embodiment are: in this embodiment, a 1080P30 camera is selected, and the field of view is 18.90°-10.65°. In the sunny suburbs, the yaw angle and pitch angle of the turntable can be obtained in real time through the encoder inside the turntable. At the same time, the tilt angle in the rolling direction is obtained in real time through the rolling gyro of the azimuth frame of the turntable. Through the inertial navigation system, the attitude angle of the geographic coordinate system is obtained in real time, including roll, heading, and pitch. The yaw angle is offset by 0.09°, the pitch angle is offset by 0.08°, and the roll angle is 3°. The final derotated image is obtained by transforming the acquired data into four coordinate systems. Note: The gyro sensor used in this experiment is Refine's TL740D sensor.

[0091] Specific steps are as follows:

[0092] Step 1: Obtain the heading angle and pitch angle of the turntable in real time through ...

Abstract

The invention provides an image racemization method and system based on multi-source sensing data fusion processing. The image racemization method comprises the steps that the course angle and the pitch angle of a rotary table are obtained in real time through an encoder in the rotary table; meanwhile, the inclination angle in the transverse rolling direction is obtained in real time through a transverse rolling gyroscope of the rotary table orientation frame; through an inertial navigation system, attitude angles including rolling, heading and pitching of an in-ground coordinate system are obtained in real time; four coordinate systems including a geographic coordinate system, a camera coordinate system, an imaging coordinate system and a pixel coordinate system are established, and the four coordinate systems are deduced layer by layer, so that the geographic coordinate system is converted into the pixel coordinate system; the angle information is converted into coordinate values ofimage pixel coordinates; and an image processing algorithm is utilized to compensate the pixel deviation in each direction, so that image racemization of multi-source sensing data fusion processing can be realized.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to an image derotation method and system based on fusion processing of multi-source sensory data. Background technique [0002] During the tracking and shooting process of the vehicle-mounted optoelectronic platform, the attitude change of the carrier aircraft and the relative movement of the target will cause the relative movement of the visual axis of the optoelectronic platform such as azimuth and pitch, resulting in the rotation of the captured image, which brings trouble to the observer and is not conducive to the observation of the target. In order to overcome this effect, it is very necessary to derotate the rotated image. With the rapid development of computer image processing technology, image derotation processing technology has a very wide range of applications in the fields of shells, missiles, aerospace, remote sensing and telemetry, scienti...
