Embodiment Construction

[0034] The invention provides a method for acquiring the displacement of aerial photography, such as figure 1 and figure 2 As shown, the methods include:

[0035] S1: The compensation motion servo mechanism determines the starting time point for controlling the movement of the aerial camera;

[0036] S2: Compensate the motion servo mechanism to obtain the flight parameters of the aircraft;

[0037] S3: Based on the flight parameters of the aircraft in step S2, the motion servo mechanism is compensated to obtain the displacement for controlling the movement of the aerial camera.

[0038] Step S1 also includes:

[0039] According to the flight inspection preset route planning point and the geographical coordinate position of the power tower according to the route planning, the starting time point of the compensation motion servo mechanism is determined.

[0040] Step S2 also includes:

[0041] Aircraft flight parameters include: flight speed, flight altitude, camera focal ...

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...
