Embodiment Construction
[0034] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0035] A method for eliminating ambiguity in space circle gesture recognition based on angle constraints provided by the present invention, such as figure 1 As shown, it is divided into a calibration phase and a measurement phase.
[0036] Calibration phase:
[0037] In step 101, the camera is calibrated to obtain internal parameters of the camera.
[0038] The specific operations are: 1) setting the target, which is a digital two-dimensional plane target generated by a computer, such as figure 2 As shown in , the target has checkerboard-like black and white squares, and there are preset feature points on the target.
[0039] select figure 2 The vertices of the white square near the center are feature points, with a total of 14×18 feature points. Of course, the number of rows and columns of feature points can b...
