Abstract
The embodiments of the present application disclose a line drawing method, a line drawing apparatus, a device, and a storage medium. Under a condition that at least one of an abscissa transformation value and an ordinate transformation value is not less than a first set threshold, a corresponding line is drawn according to an association relationship among the abscissa transformation value, the ordinate transformation value, a preconfigured transformation value coefficient, and a transformation value threshold.
Claims15
A line drawing method, comprising:
- acquiring a first frame image in an image sequence, wherein the first frame image comprises a hand of a user;
- determining, according to feature information of the hand, a first position coordinate of the hand in the first frame image;
- transforming a difference between the first position coordinate and a second position coordinate to obtain an abscissa transformation value and an ordinate transformation value corresponding to the difference on a screen of an electronic device, wherein the second position coordinate is a position coordinate of the hand in a second frame image, and the second frame image is an image before the of the first frame image in the image sequence;
- and
- drawing, under a condition that at least one of the abscissa transformation value and the ordinate transformation value is not less than a first set threshold, a corresponding line according to an association relationship among the abscissa transformation value, the ordinate transformation value, a preconfigured transformation value coefficient, and a transformation value threshold,
- wherein the method further comprises:
- under a condition that both the abscissa transformation value and the ordinate transformation value are less than a first set threshold, accumulating the abscissa transformation value with a preconfigured initial abscissa value to obtain an accumulated abscissa value, and accumulating the ordinate transformation value with a preconfigured initial ordinate value to obtain an accumulated ordinate value;
- and
- drawing, under a condition that at least one of the accumulated abscissa value and the accumulated ordinate value is greater than a sixth set threshold, a straight line of a target length starting from an end of an initial line, wherein the initial line is a line drawn according to an image before the first frame image in the image sequence, and the target length corresponds to the accumulated abscissa value or the accumulated ordinate value.
