Vehicle Scene Camera Selection From Driver Attention Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for capturing images of objects of interest in a vehicle's surroundings are impractical, especially for drivers, as they require manual operation of a camera, which is unsafe and inefficient.
Innovation Solution
A method and system that utilize multiple scene cameras mounted on a vehicle, coupled with an information capturing device to determine the user's attention direction, and then select the appropriate camera to capture images of the object of interest based on its pose relative to a reference coordinate system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually operates a camera to capture images of objects of interest, then the user can identify and retrieve information about objects, but the operation becomes unsafe and inefficient especially for drivers
Solution Approach 1:
The system enables automatic image capture by detecting the driver's attention direction through gaze tracking or head pose estimation, eliminating the need for manual camera operation. The scene cameras and processing device automatically identify and capture images of objects the driver is looking at, allowing the system to serve itself without requiring driver intervention.
Solution Approach 2:
The patent replaces the mechanical manual operation of a camera with an automated electronic system that uses information capturing devices (cameras, sensors) to detect user attention and automatically triggers scene cameras to capture images. This substitution of manual mechanical action with automated electronic detection and control resolves the safety issue while maintaining the functionality of capturing objects of interest.
2Adaptability or versatility
If multiple scene cameras are mounted on a vehicle to capture images of objects of interest, then the coverage and ability to identify objects improve, but the device complexity increases
Solution Approach 1:
The system uses information capturing devices to continuously monitor the driver's attention direction and provides feedback to the control logic. Based on this feedback, the system dynamically selects which scene camera should capture the image, ensuring that only the necessary camera among multiple cameras is activated at any given time. This feedback mechanism allows the system to manage multiple cameras efficiently without requiring all of them to operate simultaneously, thus reducing overall system complexity while maintaining comprehensive coverage.
