Traffic Light Detection via User Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems are less reliable when multiple traffic lights are within the camera's field of view, limiting the extent to which they can support drivers.
Innovation Solution
A method that involves detecting multiple signaling devices with an image, allowing users to select a subset of these devices via a display device, and outputting signals based on the detected state changes of the selected devices, which can be optical, acoustic, or haptic, enabling more extensive driver support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a camera detects multiple traffic lights in the field of view, then the system can capture more comprehensive traffic information, but the reliability of traffic light state detection decreases
Solution Approach 1:
The system segments the detection task by dividing multiple traffic lights into individually selectable targets. The display device shows multiple traffic lights separately, allowing the driver to focus on one at a time, thereby maintaining detection reliability while handling multiple traffic lights in the field of view.
Solution Approach 2:
The display device acts as an intermediary between the camera and the driver. It presents multiple traffic lights in a processed, organized manner and enables selective interaction, mediating the complexity of multiple detections into a manageable interface that preserves reliability.
2Extent of automation
If the system provides comprehensive driver support for multiple traffic lights, then the extent of automation increases, but the device complexity increases
Solution Approach 1:
The system allows the driver to self-select which traffic light to monitor from the displayed options. This self-service approach enables comprehensive automation support for multiple traffic lights while keeping the system complexity manageable, as the driver performs the selection task rather than the system requiring complex automated selection logic.

AI summary
A method for identifying a signaling state of at least one signaling device from a plurality of signaling devices includes obtaining at least one image which comprises each of the plurality of signaling devices, representing at least one first group of the plurality of signaling devices detected by the image using a display device, receiving a user input regarding the display device or regarding a representation provided by the display device, evaluating the user input and selecting a second group from the first group of the plurality of signaling devices, and detecting a signaling state of the signaling devices of the second group and outputting a signal as a function of at least one detected signaling state of a signaling device of the second group in response to a change in the signaling state. A device for carrying out such a method is also described.
