Embodiment Construction

[0013] A preferred embodiment of the present invention is described below with reference to the drawings: see figure 1 , figure 2 And Figure 3. The stereo camera consists of a stereo pan / tilt 13, a base bracket 10 and a corresponding controller 17. Among them, the three-dimensional PTZ 13 is the core of the whole system. figure 2 Shown. The stereo pan / tilt 13 consists of guide rail 16, stepping motor C 6, driving gear 15, timing belt 5, two cameras 2, 3, stereo pan / tilt 13, pallet A 2, pallet B 4, driven gear 14, frame 19 and other components. There are two guide rails 16 on the frame 19, and two pallets 2, 4 slidable on the guide rail 16 are installed. The two pallets 2, 4 are respectively installed on both sides of the synchronous belt. The two ends of the synchronous belt 5 are respectively sleeved on two gears 15 and 14, the driving gear 15 on the left side is mounted on the shaft of the stepping motor 6; and the driven gear 14 on the right side. In this way, when the steppin...

Abstract

The invention relates to a stereo camera and a self-adapting parallax adjusting method. The camera is composed of two pick-up heads mounted on a machinery platform mechanism. The opposite and synchronous movement of the two pick-up heads on the control platform can be controlled through a stepper motor, thereby the parallax of the two pick-up heads is changed. Each pick-up head is provided with an electronic zooming device; the electronic zooming device can synchronously zoom under the control of a controller and control the stepper motor to accurately control the distance of the pick-up heads according to the control algorithm while the controller zooms, so that the focus of the pick-up heads is changed within a great extent; the parallax of an obtained stereo image can be always kept in the ideal state, thereby the problem of larger parallax change can not generate due to extensive zoom. The invention has the advantages of simple structure and cheap cost and can achieve the accurate and real-time adjustment of the parallax of the stereo camera within the larger zooming scope.

Description

Technical field [0001] The invention relates to a stereo camera and an adaptive parallax adjustment method under a large zoom range, and mainly relates to the fields of broadcast television technology, computer applications and multimedia. Background technique [0002] Since the invention of the stereoscopic display technology in the 19th century, the stereoscopic display technology has been continuously evolving, and the stereoscopic display technology has also been continuously developed, from the original Wheatstone4 stereoscopic display system to the current helmet and autostereoscopic display using parallax barriers. In recent years, with the development of computer and microelectronic technology, the cost of stereoscopic displays has gradually decreased, and the public's expectations for stereoscopic displays have also increased. The development of computer graphics will of course lead to the emergence of new display games or three-dimensional movies. It also allows consume...
