Method for acquiring remote gesture tracks under camera conditions

The invention provides a method for acquiring remote gesture tracks under camera conditions and belongs to the field of man-machine interaction interfaces of computers. The method includes steps of (1) acquiring n frames of bmp images, width and height of the images and indicators storing the data by cameras; (2) sequentially processing n frames of the images and acquiring barycentric coordinates of the gesture images; (3) outputting n frames of barycentric coordinates of the n frames of the gesture images obtained by the step (2), and fitting the n frames of barycentric coordinates to obtain a third-order B-spline fitting function via a third-order B-spline; (4) drawing a track curve of the n frames of images by the third-order B-spline fitting function.
