Surveillance Camera Alignment Indicator for Zoomed View Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance cameras with high zooming capability face issues where mechanical deviations cause the object of interest to be misplaced in the zoomed-in view, making it difficult to ensure proper alignment without time-consuming adjustments.
Innovation Solution
A method and mobile unit that overlay an indicator on the zoomed-out image to indicate the position of the zoomed-in image, allowing for precise alignment of the camera by displacing the indicator from the zoomed-out center point, facilitating quicker installation and alignment without relying on camera zoom adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high zooming capability is implemented in surveillance cameras, then the ability to capture detailed zoomed-in images is improved, but mechanical deviations cause misalignment between the zoomed-out center and zoomed-in center, making installation and alignment time-consuming
Solution Approach 1:
The system performs preliminary alignment by displaying an indicator showing where the zoomed-in view will be centered relative to the zoomed-out view. This allows the installer to pre-position the camera before actual zooming, eliminating the need for time-consuming post-installation adjustments. The indicator is displayed on the display unit to guide the installer in aligning the camera correctly during installation.
2Measurement precision
If high zooming capability is implemented in surveillance cameras, then the ability to capture detailed zoomed-in images is improved, but mechanical deviations cause misalignment between the zoomed-out center and zoomed-in center, requiring manual realignment adjustments
Solution Approach 1:
The system provides visual feedback by displaying an indicator that shows the relationship between the zoomed-out center and the expected zoomed-in center position. This feedback mechanism guides the installer in real-time during installation, allowing for immediate correction of alignment issues without requiring multiple zoom-in/zoom-out cycles and manual adjustments.
3Manufacturing precision
If traditional zoom alignment methods are used, then the object of interest can be centered in zoomed-in views, but the process requires repeated zooming in and out and manual realignment which is time-consuming
Solution Approach 1:
The system performs preliminary alignment by displaying an indicator showing where the zoomed-in view will be centered relative to the zoomed-out view. This allows the installer to pre-position the camera before actual zooming, eliminating the need for time-consuming post-installation adjustments. The indicator is displayed on the display unit to guide the installer in aligning the camera correctly during installation.
Solution Approach 2:
The system creates a visual copy or representation of the zoomed-in view's center position as an overlay indicator on the zoomed-out view. This virtual indicator replicates the information that would otherwise require physical zooming to verify, allowing the installer to see the alignment relationship without actually zooming in, thus saving time while maintaining alignment precision.

AI summary
A method and mobile unit facilitate installation of a surveillance camera for monitoring an object of interest in a scene. The surveillance camera acquires a zoomed out image of the scene. The zoomed out image is displayed in a display wherein the zoomed out image has a zoomed out center point. An indicator overlaid on the displayed zoomed out image is displayed in the display, wherein the indicator and the zoomed out center point are displaced in relation to each other by a deviation. The indicator indicates the position of a zoomed in center point of a zoomed in image of the scene. The surveillance camera is directed so that the position of the object of interest and the indicator coincide so that the object of interest is included in a zoomed in image of the scene.
