Pan-tilt camera automatic signal detection and positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video surveillance, pan-tilt cameras require manual operation by personnel to adjust their focus on target regions, leading to delayed response times during emergencies, as operators need to log in and manually control the cameras.
Innovation Solution
A method and system that detect signal sources within the monitored region, differentiate between state-adjusting and position-adjusting signals, and automatically adjust the pan-tilt camera's position to align with the signal source, allowing for immediate targeting of emergency regions without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual control operation is used to adjust pan-tilt camera to target region, then the operator can control the camera position, but the trigger delay is long due to login and manual operation time
Solution Approach 1:
The pan-tilt camera system performs self-adjustment by automatically detecting signal sources and adjusting its own position to align with the target region, eliminating the need for manual operator intervention and reducing trigger delay
Solution Approach 2:
The patent replaces manual mechanical control operations with automatic signal-based control, where the camera receives position adjustment signals and automatically adjusts its pan-tilt position without human intervention
2Productivity
If automatic positioning based on signal sources is implemented, then trigger delay is reduced, but the system complexity increases due to signal detection and differentiation
Solution Approach 1:
The system uses different signal parameters (frequency, modulation pattern) to distinguish between state-adjusting signals and position-adjusting signals, enabling automatic differentiation without complex processing by using clearly distinguishable signal characteristics
Solution Approach 2:
The patent introduces signal sources as intermediaries that carry position information, allowing the pan-tilt camera to automatically determine its positioning based on detected signal characteristics without requiring complex direct control mechanisms

AI summary
The present application relates to the field of security and protection, and provides a pan-tilt control method, device and system. The method comprises: detecting whether a signal source exists in a monitoring area of a pan-tilt camera or not, the pan-tilt camera comprising a pan-tilt and a camera provided on the pan-tilt; when a signal source exists in the monitoring area, determining whether a signal emitted from the signal source is a position adjusting signal for indicating the pan-tilt to adjust the position; and when the signal emitted from the signal source is a position adjusting signal, adjusting the position of the pan-tilt according to the position of the signal source. The present application solves the problem in the prior art that an operating personnel can perform a control operation only after logging in a client by means of a terminal device and finding a corresponding pan-tilt camera, and the trigger delay of the control operation to the pan-tilt camera is long. The present application is used for controlling the pan-tilt.
