Problems solved by technology

The above-mentioned pan-tilt camera is a two-dimensional pan-tilt camera, and the two-dimensional pan-tilt camera can only adjust the camera from the horizontal and vertical two-dimensional. There may also be position differences around the axis of the lens between the pan-tilt cameras in the position state. In the prior art, there is no three-dimensional pan-tilt camera, and the two-dimensional pan-tilt camera does not have a driving device that can also drive the lens of the camera to rotate around its axis. Therefore, the on-site video image captured by the PTZ camera cannot be accurately overlapped with a picture of the scene in the video image captured by the original camera

Embodiment Construction

[0014] Figure 1~Figure 3 Among them, the three-dimensional pan-tilt camera has a pan-tilt base 1, a groove-shaped bracket 2 is arranged on the top of the pan-tilt base, and a groove-shaped bracket axis 3 perpendicular to the bottom of the groove is arranged in the middle of the bottom of the groove-shaped bracket, and the groove-shaped bracket shaft extends into the pan-tilt base. There is a horizontal motor 4 in the pan platform seat, and a transmission device 5 is connected between the horizontal motor and the grooved support shaft. The two side walls of the grooved support have respectively a grooved support shaft whose axis is on the same straight line and whose axis is parallel to the bottom of the groove. There is a cylindrical housing 7 between the hole 6 and the shaft hole of the grooved bracket. A camera 8 is arranged in the housing. The axis of the camera lens 9 is on the same straight line as the axis of the cylindrical housing. Stretch out, the both sides of housi...

Abstract

The invention relates to a three-dimensional Pan / Tilt / Zoom (PTZ) camera, which comprises a cradle head seat. The upper surface of the cradle head seat is provided with a groove-shaped support; a horizontally-rotating driving device of the groove-shaped support is arranged in the cradle head seat; a cylindrical shell is arranged on the groove-shaped support and a camera is arranged in the shell; the two sides of the shell are provided radial shell shafts; the outer side of a groove wall at one side of the groove-shaped support is provided with a rotation driving device of the shell; an inner shell is arranged in the cylindrical shell; the camera is arranged in the inner shell; a bearing is arranged between the shell and the inner shell; a lens of the camera extends out of the front ends of the inner shell and the shell; the rear end of the inner shell is provided with an inner shell shaft arranged on an inner shell axis; the rear end outside the shell is provided with an axial motor; and a transmission device is connected between the axial motor and the inner shell shaft. In order to acquire video images of a restored site and determine the positional state of the original camera during criminal investigation, the PTZ camera can be adjusted in three dimensions to make the video images shot by the PTZ camera accurately aligned with one of video images shot by the original camera.

Description

technical field [0001] The invention relates to a pan-tilt camera, in particular to a driving device for the pan-tilt camera to rotate around the lens axis. Background technique [0002] A PTZ camera is a camera with a PTZ. The pan-tilt camera has a pan-tilt base, and there is a groove-shaped bracket on the top of the pan-tilt base. In the middle of the lower side of the groove-shaped bracket, there is a groove-shaped bracket shaft perpendicular to the bottom of the groove. The groove-shaped bracket shaft extends into the pan-tilt base, and there is a horizontal motor , there is a transmission device connected between the horizontal motor and the shaft of the trough-shaped support, the side wall of the trough-shaped support has relative trough-shaped support shaft holes, and there is a cylindrical shell between the shaft holes of the trough-shaped support, in which there is a camera, the camera The axis of the lens is on the same straight line as the axis of the cylindrical...
