Imaging detection system for aerial camera under high-altitude environment condition

Abstract

The invention discloses an imaging detection system for an aerial camera under a high-altitude environment condition. The system comprises an unmanned aerial vehicle, an aerial camera module and a ground data receiving module. The aerial camera module is used for collecting image signals and motion state data of the aerial camera, carrying out compensation processing on the image signals and then sending the image signals to the ground data receiving module. The ground data receiving module is used for carrying out image quality detection on the received image signals and judging an image state aerial camera of the under the high-altitude environment. The system has the beneficial effects that lowpass filtering processing is carried out on the image signals photographed by the aerial camera under the high-altitude environment, thereby obtaining a secondary blurred image; the secondary blurred image is taken as a reference image; the change condition of the parameter information of image blocks before and after the filtering is extracted as the basis for imaging quality detection, so the defect that a traditional reference image-free imaging quality evaluation method generally is high in computing complexity is effectively solved; the operation complexity is effectively reduced; and the operation speed and the system accuracy are improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an imaging detection system for an aerial camera under high-altitude environmental conditions. Background technique [0002] As an important branch of remote sensing technology, aerial remote sensing technology is widely used in many fields, such as disaster assessment. Emergency rescue, on-site investigation, etc. With the development of UAV technology, UAVs are widely used in the field of aerial photography. The shooting process, which greatly increases the application of aerial photography technology, however, in the shooting process of aerial photography cameras, often due to some external factors, or the vibration of the fuselage, the captured image is blurred, which greatly affects the quality of the image . The quality of an image shooting directly determines whether the observation can correctly identify the object. Therefore, it is very important to evaluate the quality...
