Problems solved by technology

[0006] However, in order to track the above-mentioned subject that exceeds the maximum tilt angle of the surveillance camera by 90 degrees and continues to move in the opposite direction, the surveillance camera needs to be rotated 180 degrees in the horizontal direction. The camera cannot shoot the subject within the specified time, which is a fatal error for the surveillance function.

Embodiment Construction

[0024] Embodiments of the method of tilt control and signal processing of a surveillance camera based on the present invention and related devices will be described in detail below with reference to the accompanying drawings.

[0025] image 3 It is a schematic diagram of the composition of a monitoring camera and a pan / tilt platform to which the present invention is applied. For example, the above-mentioned monitoring camera 100 includes a zoom lens (ZM) 10, a focusing lens (FM) 11, an aperture (IM) 12, a CCD 13, and a digital signal processing system. Department (DSP) 14 (signal of vertical change), microcomputer 15, connection 16, etc. The pan / tilt 200 includes a pan motor 20, a tilt motor 21, a pan / tilt microcomputer 22, and the like.

[0026] On the other hand, the above-mentioned swing motor 20 and the tilt motor 21 respectively use a stepping motor (StepMotor). ) 21 rotates, the number of rotation steps of the swing motor 20 and the tilt motor 21 is counted, thereby c...

Abstract

The method includes: when an adjustment whose tilt angle is over 90 degree is made for a video cameral monitor sitting on a cradle, the video camera monitor is in a bottom up position; in this occasion, the invention can turns over the captured video image; even though the shooting object makes backward movement for the video camera in a rang exceeding 90 degree, the can also trace the shooting object in a certain tilt angle, and turns over the captured video image to be outputted.

Description

(1) Technical field [0001] The present invention relates to the tilt control and signal processing method of the monitoring camera, especially to a monitoring device for improving the monitoring performance on the PTZ Dome camera with functions of Pan, Tilt and Zoom. Camera tilt control and signal processing methods and related devices. (2) Background technology [0002] figure 1 It is a schematic diagram of an embodiment of an ordinary surveillance camera performing oblique shooting under the action of a pan-tilt. The surveillance camera mentioned above, such as a PTZ Dome camera, can be installed on a pan / tilt mounted on the ceiling of a specific place to be monitored. [0003] On the other hand, the above-mentioned PTZ Dome camera can change the direction of the monitoring area by performing a pan motion to rotate in the horizontal direction and a tilt motion to rotate in the vertical direction by means of the above-mentioned pan / tilt. It is also possible to use the zo...
