Panorama-Based Camera Angle Adjustment for Video Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems face high complexity and low efficiency in navigating cameras to desired surveillance locations, whether through manual adjustment or preset location settings.
Innovation Solution
A method where user equipment receives a panorama from a camera, determines the specified view by the user, calculates the corresponding surveillance angles using formulas αh = x * Width and βv = y * Height, and sends these angles to the camera to adjust its position, allowing direct access to the desired view without manual or preset location searching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of PTZ control buttons is used to navigate camera to desired location, then the camera can be adjusted to the location, but the operation complexity is high and locating efficiency is low
Solution Approach 1:
The patent introduces a panorama image as an intermediary visual interface between the user and the camera system. The panorama displays multiple candidate views with their corresponding surveillance angles, allowing users to select desired locations by simply clicking on visual elements rather than manually adjusting PTZ controls. This intermediary interface significantly reduces operation complexity while improving locating efficiency.
Solution Approach 2:
The patent creates a visual copy of the surveillance scene through the panorama image, which represents multiple camera views simultaneously. This visual copy allows users to preview and select target locations before actual camera movement occurs, eliminating the need for trial-and-error manual adjustment and greatly improving locating efficiency.
2Productivity
If preset locations are used for direct viewing, then the desired location can be accessed quickly, but the operation complexity remains high due to the need to set and manage presets
Solution Approach 1:
The panorama image serves as a visual copy of all available surveillance views, allowing users to directly click on desired locations without pre-configuring presets. This approach provides quick access to any location while eliminating the complexity of preset management, as the panorama dynamically presents all available views on demand.
Solution Approach 2:
The panorama image is dynamically generated and updated based on current camera positions and available views, replacing static preset configurations. This dynamic presentation allows users to access any surveillance location directly without needing to pre-configure or remember preset locations, reducing operational complexity while maintaining high efficiency.

AI summary
The present invention discloses a video surveillance method, device, and system, which relate to the field of video surveillance and can reduce complexity of a locating operation and improve locating efficiency. The video surveillance method includes: receiving, by a user equipment, a panorama sent by a camera; obtaining, by the user equipment, a view that is specified by a user and in the panorama; obtaining, by the user equipment according to a preset correspondence between a view and an angle, a surveillance angle corresponding to the view specified by the user; and sending, by the user equipment, the surveillance angle to the camera, so that the camera adjusts an angle of the camera to the surveillance angle. The present invention is applicable to viewing video surveillance view information.
