Problems solved by technology
[0003] However, although the traditional test scene has a clear outline, facing a single scene outline, such as a horizontal outline, a vertical outline, an oblique outline, and an outline without horizontal and vertical edges, it is difficult for the user to distinguish because the shooting device is in each Pattern deformation caused by jitter in direction
In addition, the contours of the traditional test scenes are mostly curves. When the shooting device shakes, when judging the degree of deformation of the contours of the shot scenes, it is not easy for the user to judge whether the shaking of the image comes from the original contour of the image or is affected by the shooting device. Influenced by jitter, it is impossible to get the correct test conclusion of the stability of the aircraft

Provided are a method for testing shooting stability, a calibration device, and a calibration system. The method includes: providing a calibration pattern for testing the shooting stability of the photographing device, the calibration pattern includes a first calibration pattern and a second calibration pattern, wherein the first calibration pattern extends along a first direction, and the second calibration pattern extends along a second direction. direction extension, the first direction is the horizontal direction, the second direction is the vertical direction, and the edge contours of the first calibration pattern and the second calibration pattern are composed of straight lines; the camera is controlled to photograph the calibration pattern to obtain the image of the calibration pattern , and store the acquired image; judging the shooting stability of the photographing device according to the acquired image. By providing the calibration pattern, and the photographing device photographs the calibration pattern, acquires an image of the calibration pattern, and judges the photographing stability of the photographing device according to the acquired image, the operation is simple and easy to implement.
Description
technical field [0001] The present application relates to the technical field of shooting stability testing, in particular to a method for testing shooting stability, a calibration device and a calibration system. Background technique [0002] Aircraft with shooting functions, gimbals for shooting, and other anti-vibration devices for shooting often bring different degrees of vibration to the shooting device, which affects the stability of the captured images. For example, shaking the photographing device in the vertical and horizontal directions causes the shooting screen to shake in the vertical and horizontal directions. Or image shaking is caused by high-frequency and low-frequency vibrations of the shooting device. For example, high-frequency vibrations often cause blurred pictures and blurred edges of straight lines; low-frequency vibrations often cause distortion of the picture, and straight lines captured It is distorted into an arc or S shape, etc., forming a water...
