Camera Field of View Restriction Enforcement via Server Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems lack accurate methods to determine if the field of view is within restricted areas, leading to uncertainty for users about photography or video recording permissions in locations such as business premises or private property.
Innovation Solution
A camera device that determines its field of view, transmits these coordinates to a server with a repository of restricted areas, and performs actions such as notification, boundary display, or content filtering based on overlaps, enabling or disabling capture functions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If location-based disabling is used to impose photography restrictions, then the restriction enforcement is automated, but the system only checks camera location and not the field of view, leading to inaccurate restriction application
Solution Approach 1:
The system segments the camera's viewing area into a field of view that can be independently analyzed. Instead of treating the entire camera location as a single unit, the patent divides the viewing space into discrete coordinates that can be checked against restricted area databases, allowing precise determination of whether any part of the field of view overlaps with restricted zones.
Solution Approach 2:
The patent transitions from checking only the camera's geographic location (2D position) to analyzing the three-dimensional field of view coordinates. By adding the dimensional aspect of viewing angle and spatial orientation, the system can accurately determine whether objects within the field of view fall within restricted areas, resolving the inaccuracy of location-only checking.
2Loss of information
If printed signs are used to indicate photography restrictions, then the restriction information is provided to users, but users must deduce exact allowed and restricted locations, which is difficult to know with accuracy
Solution Approach 1:
The system provides real-time feedback to users by automatically checking field of view coordinates against restricted area databases and notifying users when restricted areas are detected. This eliminates the need for users to interpret printed signs and deduce restricted zones, as the system actively communicates restriction status based on current camera orientation and location.
Solution Approach 2:
The patent enables the camera system to automatically determine and communicate restriction status without requiring user interpretation of external signs. The system self-services by autonomously checking coordinates, comparing with restricted area data, and providing notifications, freeing users from the cognitive burden of understanding complex sign-based restriction systems.
3Measurement precision
If the camera checks field of view coordinates against restricted areas, then accurate restriction determination is achieved, but the device complexity increases due to server communication and coordinate processing
Solution Approach 1:
The patent introduces a server as an intermediary that stores comprehensive restricted area coordinate data and performs complex comparison operations. The camera device sends field of view coordinates to the server, which handles the computationally intensive task of checking overlaps with restricted zones and returning results, thereby keeping the camera device itself relatively simple while achieving high detection accuracy.
Data Source
AI summary
Systems and method for determining and indicating camera restrictions are disclosed. A method includes: receiving, by a camera device, an input to capture content; determining, by the camera device, a field of view of the camera device; transmitting, by the camera device, data defining the field of view to a server; receiving, by the camera device, a data structure from the server; and based on the data structure, performing one of: capturing the content with the camera device without restriction; and performing at least one restriction action at the camera device.
