Problems solved by technology

However, these devices have disadvantages such as expensive and complicated to use, and obtaining an ultra-wide viewing angle in a low-resolution image will lose the resolution of objects in the scene, and the image edges of the wide-angle lens will inevitably be distorted

Abstract

The invention relates to a fan-sweep splicing method applied to a double-infrared low-altitude detection system for land defense monitoring, and belongs to the technical field of video monitoring image processing. The method shown uses two infrared cameras placed up and down to obtain images corresponding to different pitch angles, and sweeps continuously within the specified detection azimuth, and obtains different azimuths corresponding to multiple scene points by means of fixed angles or fixed time intervals. According to the ratio of the current azimuth angle to the detection range, the stitching position of the image to be stitched in the panoramic picture is calculated, so as to form a complete scene picture. This method can realize the real-time generation of panoramic pictures in a large scene range, and has a high splicing rate, and the method is not limited to the placement position and angle of the land defense turntable.

Description

technical field [0001] The invention relates to a fan-sweep splicing method applied to a double-infrared low-altitude detection system for land defense monitoring, and belongs to the technical field of video monitoring image processing. Background technique [0002] With the development of technologies such as video surveillance and panorama stitching, the functions of large scene surveillance and real-time target detection have attracted more and more attention. In actual scientific research and engineering projects, high-resolution images that exceed the perspective of the human eye are often used. Due to the limitation of distance, the angle of view of ordinary digital cameras often cannot meet the needs, and some super-sized objects cannot be captured with a single photo. In order to obtain high-resolution images with large viewing angles, people often use wide-angle lenses and scanning cameras to partially solve this problem. However, these devices have the disadvanta...
