Description

测试拍摄稳定性的方法、校准装置和校准***Method, calibration device and calibration system for testing shooting stability 技术领域Technical field
本申请涉及拍摄稳定性测试技术领域，具体涉及一种测试拍摄稳定性的方法、校准装置和校准***。This application relates to the technical field of shooting stability testing, and in particular to a method, calibration device and calibration system for testing shooting stability.
背景技术Background technique
带有拍摄功能的飞行器、拍摄用的云台、其他拍摄用的防振装置等设备往往会给拍摄装置带来不同程度的振动，影响拍摄得到的画面的稳定性。例如，使拍摄装置朝上下、左右方向抖动，造成拍摄画面朝上下、左右方向抖动。或者由于拍摄装置的高频、低频抖动造成图像的抖动，例如，高频振动往往会造成画面模糊、所拍的直线条边缘模糊；低频振动往往造成画面的扭曲变形，所拍的直线条则会被扭曲变成弧形或S型等，形成水波纹状，俗称视频水波纹。因此，在出厂前，有必要测试其稳定性，以保证拍摄得到的画面的稳定性。以飞行器为例，传统的测试拍摄稳定性的方法为在白天阳光充足的环境下，飞行器飞行并拍摄外形轮廓清晰的景物(如外形规则的建筑物)，通过景物变形的程度判断飞行器是否稳定。Equipment such as aircraft with shooting functions, gimbals for shooting, and other anti-vibration devices for shooting often bring varying degrees of vibration to the shooting device, which affects the stability of the picture obtained by shooting. For example, the camera shakes up and down and left and right, causing the shooting screen to shake up and down and left and right. Or due to the high-frequency and low-frequency jitter of the shooting device, the image jitters. For example, the high-frequency vibration often causes the picture to be blurred and the edges of the straight line shot blurred; the low-frequency vibration often causes the distortion of the picture, and the straight line It is twisted into an arc or S shape, etc., forming a water ripple, commonly known as video water ripple. Therefore, it is necessary to test its stability before leaving the factory to ensure the stability of the captured images. Taking an aircraft as an example, the traditional method of testing the shooting stability is to fly the aircraft in a sunny environment during the day and shoot a scene with a clear outline (such as a building with a regular appearance), and judge whether the aircraft is stable by the degree of deformation of the scene.
然而，传统的测试景物尽管具有清晰的外形轮廓，面对单一的景物轮廓，例如水平轮廓、竖直轮廓、倾斜轮廓，以及不具备水平、竖直边缘的轮廓，用户难以区分因拍摄装置在各个方向的抖动所造成的图案变形。此外，传统的测试景物的轮廓多数为曲线，在拍摄装置抖动时，在判断所拍摄的景物的轮廓变形的程度时，用户不容易判断出图像的抖动，来自于图像的原始轮廓还是受拍摄装置抖动的影响，进而无法得到正确的飞行器稳定性的测试结论。However, although the traditional test scene has a clear outline, it faces a single scene outline, such as horizontal outline, vertical outline, oblique outline, and outline without horizontal and vertical edges. Pattern distortion caused by direction jitter. In addition, the contours of traditional test scenes are mostly curved. When the camera shakes, when judging the degree of deformation of the shot scene, it is not easy for the user to determine whether the image shake comes from the original contour of the image or from the shooting device. The impact of jitter, and then it is impossible to get the correct test conclusion of aircraft stability.

In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
请参考图1，本申请实施例提供一种用于测试拍摄装置的拍摄稳定性的校准图案。校准图案包括第一校准图案11以及第二校准图案13。Please refer to FIG. 1, an embodiment of the present application provides a calibration pattern for testing the shooting stability of a shooting device. The calibration pattern includes a first calibration pattern 11 and a second calibration pattern 13.
其中，第一校准图案11沿第一方向延伸，第二校准图案13沿第二方向延伸，第一方向与第二方向相交。优选的，第一方向和第二方向相交的夹角呈锐角、直角、或者钝角。从而，可以节约图案所占的空间，并方便用户确认拍摄装置在各个方向的抖动。进一步的，第一方向和第二方向相交的夹角呈60°-120°。进一步优选的，第一方向和第二方向相交的夹角呈90°。优选的，第一校准图案11和第二校准图案13相交，可以减少第一校准图案11和第二校准图案13的占用面积。The first calibration pattern 11 extends along a first direction, and the second calibration pattern 13 extends along a second direction, and the first direction intersects the second direction. Preferably, the intersection angle between the first direction and the second direction is an acute angle, a right angle, or an obtuse angle. Therefore, the space occupied by the pattern can be saved, and it is convenient for the user to confirm the shaking of the camera in various directions. Further, the angle between the first direction and the second direction is 60°-120°. Further preferably, the angle between the first direction and the second direction is 90°. Preferably, the first calibration pattern 11 and the second calibration pattern 13 intersect, which can reduce the occupied area of the first calibration pattern 11 and the second calibration pattern 13.
所述拍摄装置接收透过所述校准图案的光线或经所述校准图案反射的光线，以获取所述校准图案的图像，所述校准图案的图像用于判断所述拍摄装置的拍摄稳定性。The imaging device receives light transmitted through the calibration pattern or light reflected by the calibration pattern to obtain an image of the calibration pattern, and the image of the calibration pattern is used to determine the shooting stability of the imaging device.
其中，拍摄装置可以为照相机、摄像机、带有摄像头的智能手机、平板电脑等拍摄设备。这些拍摄设备可以设置在无人机、云台或其他拍摄用的防振装置上。以无人机为例，拍摄装置(假设为摄像机)搭载在无人机上，无人机在空中飞行并拍摄时，需要测试拍摄的稳定性，避免画面抖动影响成像品质。Among them, the shooting device may be a camera, a video camera, a smart phone with a camera, a tablet computer and other shooting equipment. These shooting equipment can be set on drones, pan-tilts or other anti-vibration devices for shooting. Take a drone as an example. The camera is mounted on the drone. When the drone is flying and shooting in the air, it is necessary to test the stability of the shooting to avoid image jitter from affecting the image quality.
摄像机拍摄得到二维的视频或者图片，拍摄稳定性的考核因素为在视频或者图片中是否有图像的抖动。可以通过观察视频或者图片中采集的校准图案的形状加以判断。The camera captures a two-dimensional video or picture, and the assessment factor for shooting stability is whether there is image jitter in the video or picture. It can be judged by observing the shape of the calibration pattern collected in the video or picture.
判断方法为：观察视频或者图片中的沿第一方向的第一校准图案11、第二方向的第二校准图案13的图像有弯曲和边缘模糊现象时，则说明拍摄稳定性不足，测试不通过，需要提高稳定性。如果不存在弯曲和边缘模糊现象，则说明拍摄稳定性足够，证明测试通过。之所以需要第一校准图案11和第二校准图案13的图像，是因为抖动可能是多个方向的，如仅设置第一校准图案11，当抖动方向与第一方向相交时，第一校准图案11的图像发生弯曲或者边缘模糊，能测试拍摄稳定性的真实情况，但是，当抖动方向与第一方向平行时，第一校准图案11并不会发生弯曲或者边缘模糊现象，无法准确的测试出拍摄稳定性的真实情况。而设置第二校准图案13后，由于第二校准图案13与第一校准图案11的延伸方向相交，故当抖动方向与第一方向平行时，第二校准图案13会产生弯曲或者边缘模糊现象，从而准确的测试出拍摄稳定性的真实情况。这样不论抖动方向在哪个方向，通过观察第一校准图案11和第二校准图案13的图像都能准确的判断拍摄稳定性的情况。The judging method is as follows: when the images of the first calibration pattern 11 in the first direction and the second calibration pattern 13 in the second direction in the video or picture are curved and blurred, it means that the shooting stability is insufficient and the test fails. , Need to improve stability. If there is no bending and blurred edges, it means that the shooting stability is sufficient and the test is passed. The reason why the images of the first calibration pattern 11 and the second calibration pattern 13 are needed is that the jitter may be in multiple directions. For example, only the first calibration pattern 11 is provided. When the jitter direction intersects the first direction, the first calibration pattern The image of 11 is bent or the edge is blurred, which can test the real situation of the shooting stability, but when the jitter direction is parallel to the first direction, the first calibration pattern 11 will not be bent or the edge is blurred, and it cannot be accurately tested. The real situation of shooting stability. After the second calibration pattern 13 is set, since the second calibration pattern 13 intersects the extension direction of the first calibration pattern 11, when the jitter direction is parallel to the first direction, the second calibration pattern 13 will bend or have blurred edges. So as to accurately test the real situation of shooting stability. In this way, no matter which direction the shaking direction is, by observing the images of the first calibration pattern 11 and the second calibration pattern 13, the shooting stability can be accurately determined.
抖动包括低频抖动和高频抖动，当发生低频抖动时，第一校准图案11和/或第二校准图案13的图像会扭曲变形形成弯曲的弧形或者S形，形成水波纹状，当图像为视频时，俗称视频水波纹。当发生高频抖动时，第一校准图案11和/或第二校准图案13的图像会高频 抖动，画面模糊不清，第一校准图案11和/或第二校准图案13的图像除了变形，边缘也会模糊。The jitter includes low-frequency jitter and high-frequency jitter. When low-frequency jitter occurs, the image of the first calibration pattern 11 and/or the second calibration pattern 13 will be distorted and deformed into a curved arc or S shape, forming a water ripple. When the image is In video, it is commonly known as video water ripple. When high-frequency jitter occurs, the images of the first calibration pattern 11 and/or the second calibration pattern 13 will be high-frequency jitter, the picture is blurred, and the images of the first calibration pattern 11 and/or the second calibration pattern 13 are deformed. The edges will also be blurred.
因此，本申请提供的校准图案，通过设置延伸方向相交的第一校准图案11和第二校准图案13，通过拍摄装置接收第一校准图案11和第二校准图案13透过的光线或反射的光线，以获取校准图案的图像，通过观察图像的形状可以判断拍摄的稳定性，结构简单，易于实现。Therefore, the calibration pattern provided in the present application is provided with the first calibration pattern 11 and the second calibration pattern 13 whose extension directions intersect, and the light transmitted or reflected by the first calibration pattern 11 and the second calibration pattern 13 is received by the camera. To obtain the image of the calibration pattern, the stability of the shooting can be judged by observing the shape of the image, and the structure is simple and easy to implement.

设置多条第一校准图案11等间距间隔设置，和/或多条第二校准图案13等间距间隔设置，当拍摄装置抖动时，第一校准图案11和/或第二校准图案13中的每条弯曲方向和程度基本一致，更便于观察抖动情况。A plurality of first calibration patterns 11 are arranged at equal intervals, and/or a plurality of second calibration patterns 13 are arranged at equal intervals. When the camera shakes, each of the first calibration patterns 11 and/or the second calibration patterns 13 The strip bending direction and degree are basically the same, which makes it easier to observe the jitter.

Further, the spacing distance between the plurality of first calibration patterns 11 may be equal to the spacing distance between the plurality of second calibration patterns 13. In addition, the specific value of the separation distance between two adjacent first calibration patterns 11 and/or two adjacent second calibration patterns 13 is not limited, and the specific value can be adjusted according to the possible jitter conditions of different photographing devices, and when The smaller the specific value is, the more sensitive the response to jitter is, that is, the more likely it is that two adjacent first calibration patterns 11 and/or two adjacent second calibration patterns 13 overlap, and it is easier to distinguish jitter. . When the image of the first calibration pattern 11 and/or the second calibration pattern 13 is a video, two adjacent calibration patterns overlap due to jitter, which is also called video jitter.
