Abstract:
1. A remote control system, comprises a controlled apparatus ( 120 ) and a remote controller ( 100 ), the controlled apparatus ( 120 ) comprises a processing control system ( 121 ) and an instruction execution unit ( 125 ), wherein, the processing control system ( 121 ) further comprises a characteristic composition extraction unit ( 123 ), an instruction parsing unit ( 124 ), the characteristic composition extraction unit ( 123 ) is connected to a plurality of video capturing devices ( 122 ), extracts image of the characteristic composition from obtained video image, and processes and determines position of the extracted image, the instruction parsing unit ( 124 ) is used for interpreting moving track of the characteristic composition extracted by the characteristic composition extraction unit ( 123 ) to corresponding instruction according to predetermined mapping relationship between the moving track of the characteristic composition and instruction and gives the instruction execution unit ( 125 ) the instruction to execute; wherein the processing control system ( wherein, the process of mapping the position of the remote controller from the image coordinate to the screen coordinate of the display is: supposing the screen width is Width_scr, the height is Height_scr, then point (u,v) on the screen satisfies following conditions: Width_scr, Height_scr are natural numbers, u is a nonnegative integer smaller than Width_scr, and v is a nonnegative integer smaller than Height_scr; supposing the width of the imaging plane is Width_cam, the height is Height_cam, supposing the operation area of the remote controller is an area imaging in a certain rectangle, supposing the left top angular point is (x_ul, y_ul), and the right top angular point is (x_lr, y_lr), wherein, x_ul, y_ul, x_lr, y_lr are all integers, and 0≦x_ul<x_lr<Width_scr, 0≦y_ul<y_lr<Height_scr; supposing the position of the remote controller in the imaging plane of the camera is (x_cam, y_cam), (x_scr, y_scr) the position is after mapping to the screen coordinate system, then the mapping relationship can be expressed as follows:
