Problems solved by technology
This method generally uses cameras or video cameras with low resolution, which is not suitable for occasions that require high image quality.
When using a high-resolution camera or video camera, due to the vibration of the carrier platform, the pitch, roll, and yaw of the carrier during shooting, the photos taken often appear blurred, twisted, rotated, etc., which affect the shooting effect. , increasing the difficulty of post-processing, even difficult to use, and it is not convenient for large-area image stitching in the later stage

The invention discloses a light airborne three-axis stabilization image device which comprises a tilting stabilizing shafting, a horizontal rolling stabilizing shafting, a course stabilizing shafting and an image component. The tilting stabilizing shafting comprises a tilting frame, a tilting driving motor, a tilting angle sensor, a titling supporting bearing, a tilting shaft and an attitude sensor. The horizontal rolling stabilizing shafting comprises a horizontal rolling frame, a horizontal rolling driving motor, a horizontal rolling angle sensor, a horizontal rolling supporting bearing and a horizontal rolling shaft. The horizontal stabilizing shafting comprises a course bearing, a course inner frame, a course outer frame and a course driving motor. The image component comprises a connecting plate, a high-accuracy attitude sensor, a sealing lens cone, an ultrahigh-resolution digital camera, a high-definition television camera and a top sensor. The light airborne three-axis stabilization image device is small in size and light in weight, shot pictures are clear, distortion and rotating are avoided, and the device is very suitable for carrying out mapping, searching, shooting, picture recording and the like on a target vertically downwards under a military and / or civil airborne environment.
Description
technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a light airborne three-axis stabilized image device. Background technique [0002] Due to the needs of resource exploration, traffic planning, geological analysis, military surveying and mapping, etc., it is usually necessary to take intuitive photos of the terrain and landforms in a certain area or range, and form a whole picture of the area after technical processing. Camera method to take pictures. Generally, the resolution of the camera or video camera used in this method is not high, so it is not suitable for occasions requiring high image quality. When using a high-resolution camera or video camera, due to the vibration of the carrier platform, the pitch, roll, and yaw of the carrier during shooting, the photos taken often appear blurred, twisted, rotated, etc., which affect the shooting effect. , increasing the difficulty of post-processing, even diff...
