Problems solved by technology

However, the currently commonly used dual-target digital camera monitoring visibility technology can only capture images at a fixed height and a fixed direction. The detection accuracy is not high, so it is necessary to study a more representative and high detection accuracy digital camera monitoring visibility detection method

Abstract

A visibility detection method with an unmanned aerial vehicle-mounted catadioptric panoramic stereo camera is provided. A visibility detection system includes an unmanned aerial vehicle-mounted catadioptric panoramic stereo camera unit, a standard plate unit, a wireless transmission unit and a data processing terminal unit; the unmanned aerial vehicle-mounted catadioptric panoramic stereo camera unit adopts the unmanned aerial vehicle-mounted catadioptric panoramic stereo camera for shooting a panoramic stereo image; the standard plate unit is circular plates with black interior and white exterior, each two plates form a group, the plates are placed on all sides, four groups are placed in total four mutually perpendicular directions, and each circular plate can be lifted vertically in a lifting track; the wireless transmission unit is used for transmitting the panoramic stereo image shot by the unmanned aerial vehicle-mounted catadioptric panoramic stereo camera unit in the air to the ground data processing terminal unit; the data processing terminal unit receives the panoramic stereo image and performs processing calculation to obtain the level visibility value.

Description

technical field [0001] The invention relates to a visibility detection system and method for a catadioptric panoramic stereo camera carried by an unmanned aerial vehicle, especially a system and method for detecting horizontal visibility values ​​on any atmospheric horizontal layer based on panoramic stereo image processing. Background technique [0002] Atmospheric visibility is an important meteorological observation factor. Its prediction is not only used in the weather analysis of the meteorological part, but also widely used in the fields of aviation, navigation, road traffic, military and environmental monitoring. It is an important factor affecting aviation, navigation, road traffic and military One of the important factors such as activities. Weather with low visibility often causes delays, congestion, and even road closures and suspension of flights. At present, the commonly used visibility instruments mainly include forward scattering visibility detector and trans...
