Embodiment Construction

[0048] Such as figure 1 As shown, it includes supporting towers 1 in spatial distribution, three or four supporting towers 1 form a suspension cable frame, one end of the traction cable 2 is connected with the camera pan platform 3, the other end of the traction cable 2 is connected to the transmission unit 5 through the support tower 1, and the traction cable 2 is a steel wire rope or other flexible ropes. The transmission unit 5 at least includes a pulley assembly 9 for controlling the telescopic movement of the traction rope 2, a winding mechanism 10 and a motor 11, so that the camera pan-tilt 3 can move three-dimensionally in the space of the suspension frame.

[0049] Photography camera 12 is installed on the photography camera cloud platform 3, transmission unit 5 is electrically connected with computer control unit 8 by control unit 6, and computer control unit 8 is electrically connected with analog photography camera mechanism 4, and computer control unit 8 is by detec...

Abstract

The invention relates to a control technology for a photograph camera position, particularly to a control method for position of a photograph camera hauled by a suspension cable. The control method is characterized in that a suspension cable frame, consisting of a support tower and a traction cable is included; one end of the suspension cable is connected with a photograph and videotape cradle head and the other end is respectively connected with a transmission unit through the support tower; the transmission unit is electrically connected with a computer control unit which is electrically connected with a stimulated photograph and videotape mechanism; the computer control unit acquires space motion parameters of a cameraman controlled handle of the stimulated photograph and videotape mechanism by a state sensing and detecting unit for detecting the stimulated photograph and videotape mechanism, and then controls the transmission unit to ensure that the photograph camera fixed on the photograph and videotape cradle head three-dimensionally moves in the space of the suspension frame, formed by the space support tower, and the photograph camera and the cameraman controlled handle are operated synchronously. The photograph camera can be used for not only shooting at a fixed position, but also dynamic shooting and tracing shooting.

Description

technical field [0001] The invention relates to a position control technology of a photographic camera, especially a control method for a position of a photographic camera pulled by a suspension cable. Sports games such as football, horse racing, etc. Background technique [0002] In the shooting of live TV, movie studios, large-scale stage performance venues, large-scale open-air singing and dancing parties, celebrations, large-scale sports games such as football, horse racing, etc., the existing camera positions are mainly composed of fixed positions, Shoulder movement, tracking, orbital movement, aerial photography, rocker and other methods to achieve. [0003] The fixed position is suitable for medium and close-range shooting, typical applications such as photo studios, conference live broadcasting, etc. In this way, the control equipment of the camera position is simple, but the picture captured is single and lacks dynamic feeling. [0004] The shoulder-mounted mobil...
