Aerial video shooting displacement acquiring method and aerial video shooting movement control method

Abstract

The invention provides an aerial video shooting displacement acquiring method and an aerial video shooting movement control method. The aerial video shooting displacement acquiring method comprises the following steps: a compensation movement servo mechanism determines the start time when an aerial camera moves under control; the compensation movement servo mechanism acquires the flight parameters of an aircraft; and the compensation movement servo mechanism gets the displacement by which the aerial camera moves under control. According to the flight altitude and speed of the aircraft, the focal length and exposure time of the shooting camera and the attitude information of a camera platform, the aerial camera is driven to move through aerial video shooting displacement acquisition. According to the operation speed of the compensation movement servo mechanism and the shooting time of the shutter of the camera, the forward image shift deviation of a target in the focal plane generated by movement of the target and the camera in unit exposure time and the rotary image shift deviation caused by the attitude of the camera platform during high-speed flight of the aircraft in the aerial video shooting process are eliminated. Through aerial video shooting displacement acquisition, the aerial camera is relatively stationary in space at the moment of shooting exposure, and the shooting of the shooting target is completed.

Description

technical field [0001] The invention relates to the field of aerial photography, in particular to a method for acquiring displacement of aerial photography and a method for controlling movement of aerial photography. Background technique [0002] Every year, electric power companies have to invest huge manpower and material resources to carry out regular inspections on transmission lines, so as to keep abreast of and understand the operation of transmission lines, changes in the environment around the lines and line protection areas, and timely discover and eliminate hidden dangers. [0003] During the power inspection process of the photoelectric pod mounted on the unmanned helicopter, due to the limitation of temperature, altitude and other conditions, the aircraft hovers in front of the tower to take pictures, and the output power of the aircraft engine reaches the maximum, which has a certain impact on the safety of the aircraft. Long-term hovering and shooting takes a l...

AI Technical Summary

Problems solved by technology

However, when shooting in the flight state, due to the fast flight speed of the aircraft, the movement of the target and the camera within the unit exposure time will cause the forward image motion difference of the target at the focal plane and the rotational image motion deviation caused by the attitude of the camera platform.

The captured image will appear out of shadow, blur, etc.
