Collision Detection Platform Using Intermediary Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles often fail to detect pedestrians stepping into their path due to limitations in sensor detection and processing delays, leading to potential collisions, especially when sensors cannot detect individuals until they are within their field of view.
Innovation Solution
A collision detection platform that processes data from cameras, on-board vehicle systems, user devices, and infrastructure equipment to identify potential collisions and take preventive actions, such as adjusting traffic light phases or vehicle speed, to avoid collisions by flagging dangerous intersections and rerouting vehicles.

Engineering Contradiction Analysis
1Measurement precision
If sensors are used to detect pedestrians, then detection capability is improved, but detection is only possible when pedestrians are within the field of view, leading to late detection
Solution Approach 1:
The patent introduces camera systems positioned at strategic locations (overhead, roadside, or on other vehicles) as intermediary detection devices. These cameras capture images of pedestrians before they enter the autonomous vehicle's sensor field of view, serving as a mediator that extends the effective detection range and provides early warning of potential hazards.
Solution Approach 2:
The system performs preliminary detection of pedestrians using camera systems before the autonomous vehicle's sensors can detect them. By capturing images in advance and analyzing pedestrian trajectories, the system prepares collision risk assessments and potential avoidance maneuvers before the actual hazard reaches the vehicle's detection range.
2Speed
If processing time is reduced to avoid collisions, then response speed is improved, but complex data analysis from multiple sources requires significant processing time
Solution Approach 1:
The patent divides the collision avoidance system into multiple independent processing modules: camera systems for image capture, separate trajectory analysis components, collision risk assessment modules, and vehicle control systems. Each module processes specific aspects of the data independently, allowing parallel computation and reducing overall processing time while maintaining comprehensive analysis.
Solution Approach 2:
The system implements real-time feedback loops where collision risk assessments are continuously updated based on current pedestrian positions and vehicle trajectories. The feedback mechanism prioritizes processing of high-risk scenarios, dynamically adjusting computational resources to focus on the most critical threats, thereby reducing response time for urgent situations.
3Measurement precision
If multiple data sources are integrated to improve detection accuracy, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The patent employs a unified data processing platform that handles multiple data sources (camera images, LIDAR data, GPS coordinates, traffic signal information) through a common architecture. This universal processing system uses standardized interfaces and protocols to integrate diverse inputs, reducing the complexity that would arise from separate processing chains for each data source while maintaining high detection accuracy.

AI summary
A device can receive data related to a roadway. The data can include video data of the roadway. The device can determine a pixel area of objects shown in the video data. The device can determine that a vehicle and an individual are associated with the roadway at a same time. The device can determine a protective zone around the individual based on a first pixel area of the individual. The protective zone can be associated with detecting a potential collision between the vehicle and the individual. The device can determine a first location and movement of the vehicle relative to a second location and movement of the individual. The device can predict that a second pixel area of the vehicle is to intersect the protective zone of the individual. The device can detect the potential collision. The device can perform one or more actions.
