Problems solved by technology
[0002] In the automatic recording of school courses, it is necessary to use the camera tracking system to locate and track students. Currently, there are single-camera tracking systems and dual-camera tracking systems. The positioning is not accurate, and the application is very limited; although the dual cameras can realize the static positioning in the three-dimensional space, when controlling the two cameras to perform close-up operations through dynamic tracking and positioning, professionals need to be involved at all times, and many professional parameters need to be set. The operation process is quite complicated. Moreover, the accuracy of tracking and positioning is low, and it often requires multiple adjustments manually, which is time-consuming

Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:
[0025] See figure 1 , the present invention relates to a kind of camera position tracking method, and its preferred embodiment comprises the following steps:
[0026] Step S101: acquiring image data of a target object through the first camera and the second camera respectively;
[0027] For example, see figure 2 , points A, B, C and D are 4 reference points respectively, point O 1 and point O 2 are the first camera and the second camera respectively, the line O 1 o 2 Parallel to side CD in the rectangle, point S is the target object.
[0028] Step S102: According to the image data of the target object and the image data of the four pre-stored reference points, respectively calculate and acquire the coordinate parameters of the target object when each reference point is used as a reference, so as to obtain four sets of coordinate parameters of...

The invention discloses a camera positioning and tracking method and a relevant system. The camera positioning and tracking method comprises the steps that image data of a target object are obtained through a first camera and a second camera; the coordinate parameters of the target object when the four reference points are taken as the reference are calculated and obtained according to the image data of the target object and the image data of the four pre-stored reference points, so that four groups of coordinate parameters of the target object are obtained; the average coordinate parameter of the four groups of coordinate parameters is obtained through calculation; a third camera position parameter matrix corresponding to the target object is obtained through calculation according to four groups of position parameter matrixes corresponding to the four pre-stored reference points, the lengths and widths of the matrixes and the average coordinate parameter of the target object. The camera positioning and tracking method and the relevant system have the advantages that tracking and positioning are accurate, operation is easy, and the method and system can be used by non-professionals conveniently and flexibly.
