[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0022] Such as figure 1 As shown, a dynamic geometry multi-coordinate system implementation method, it includes the following steps:
[0023] S1. Determine the dynamic variables of the dynamic geometric image;
[0024] S2, extracting dynamic variables to form a feature vector sequence;
[0025] S3. Select the origin of the multi-coordinate system in the feature vector space;
[0026] S4. Map the feature vector sequence in each coordinate system to form multiple coordinate systems.
[0027] The dynamic variables include T 1 …T n .
[0028] The multi-coordinate system includes one or both of a two-dimensional coordinate system composed of x-axis and y-axis and a three-dimensional coordinate system composed of x-axis, y-axis and z-axis. ...
