Embodiment 1
[0083] Please refer to Figure 2-4 , Embodiment 1 of the present invention is: a method for calibrating a virtual image and a real space, which can be applied to scenes related to visual effects such as movies, TV, network videos, and live broadcasts. When the real space is aligned with the real space of the non-real space (hereinafter referred to as the virtual space), in order to achieve visual effects such as positional relationship and perspective that all the content in the virtual space has the same positional relationship and perspective as the content in the real space.
[0084] In this embodiment, the positioning system can be installed on such as image 3 The position shown, and the position information given by the positioning system can be obtained in real time. The position information is based on the position information of the installation position, and the picture of the camera can be obtained in real time.
[0085] Such as figure 2 As shown, the method incl...
Embodiment 2
[0120] This embodiment is a specific application scenario of Embodiment 1. In an actual scenario, the following process can be adopted:
[0121] 1. Calibrate the calibration tooling and obtain the coordinates of the four active luminous points on it;
[0122] 2. Put the calibration equipment into the field, turn on the camera and positioning system;
[0123] 3. Open the software to obtain the camera image;
[0124] 4. Change the position of the camera so that it can always see the tooling;
[0125] 5. After the camera stabilizes, select the positions of the four active light-emitting points from the screen;
[0126] 6. Repeat 4 and 5 at least 3 times to get the final result.
[0127] 7. If it is necessary to improve the accuracy and reduce the error, repeat 4 and 5 several times until a satisfactory result is obtained.
[0128] 8. Import the calibration result into the virtual-real synthetic camera system developed by us, or input the result value to any other position tha...
Embodiment 3
[0130] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:
[0131] Establishing a first coordinate system according to the preset four points, and respectively recording the three-dimensional space coordinates of the four points in the first coordinate system, the first coordinate system being a spatial Cartesian coordinate system;
[0132] Respectively record the two-dimensional coordinates of the four points in the two-dimensional coordinate system of the camera screen;
[0133] According to the three-dimensional space coordinates and two-dimensional coordinates of the four points, calculate the positional relationship of the optical center position of the camera in the first coordinate system to obtain the first matrix;
[0134] Obtaining the positional relationship of the location where the positio...
