Security Camera Orientation Sensor for Automatic Image Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation process of security cameras, particularly fisheye and dome cameras, requires manual input of orientation information for leveling and image correction, which is time-consuming and prone to errors.
Innovation Solution
Incorporating orientation sensors, such as accelerometers, into security cameras to automatically detect their orientation and provide feedback systems like LEDs or speakers for accurate installation and image de-warping/rotation, eliminating the need for manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual input of orientation information is used during installation, then the camera can be installed with basic functionality, but the installation process becomes time-consuming and error-prone
Solution Approach 1:
The camera system performs self-orientation by using an orientation sensor to automatically detect its own spatial orientation and transmit this information to the control system, eliminating the need for manual orientation input during installation. The system serves itself by autonomously determining and communicating its orientation state.
Solution Approach 2:
The manual mechanical process of physically orienting and manually inputting camera orientation information is replaced with an automated sensor-based system. The orientation sensor electronically detects orientation data, substituting the manual mechanical adjustment and data entry process with automated detection and transmission.
2Reliability
If manual input of orientation information is required, then the system can operate with simpler hardware, but human error increases and reliability decreases
Solution Approach 1:
The orientation sensor provides automatic feedback about the camera's spatial orientation to the control system. This feedback mechanism ensures accurate orientation detection without relying on manual input, thereby improving reliability while the added complexity is confined to the sensor and communication components rather than the overall system architecture.
3Measurement precision
If orientation sensors are added to automatically detect camera orientation, then installation accuracy improves and human error is reduced, but device complexity increases
Solution Approach 1:
The orientation sensor acts as an intermediary component that bridges the physical camera orientation and the digital control system. It detects the physical orientation state and converts it into electronic orientation data that can be transmitted to the control system, enabling precise measurement while isolating the complexity to a dedicated sensor module rather than integrating it throughout the entire system.

AI summary
A security camera includes a camera body and a body orientation sensor for detecting an orientation of the camera body. The security camera can include an orientation feedback system used with the body orientation sensor to adjust a position of the security camera to true camera. This orientation feedback system indicates degree to which the camera body is off horizontal/vertical. The security camera is part of a video security system that has an image processing unit for de-warping and/or rotating (e.g., 90 degrees) a raw image based on the orientation detected by the body orientation sensor.
