Racing Vehicle Monitoring Using Sensor-Triggered Image Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera monitoring systems for racetracks face challenges in managing high-speed image and data flow, particularly in capturing accurate images of racing vehicles crossing the finish line, leading to excessive data storage and complex evaluation processes.
Innovation Solution
Implementing a device with a recording controller that restricts image recording to a defined time window around the section of track of interest, using a sensor device to detect the traversing event and a marking device to mark relevant images, thereby reducing data storage and simplifying evaluation by storing only markers in an event list.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-speed cameras are used to monitor racing vehicles crossing the finish line, then the accuracy of capturing the racing event is improved, but the quantity of images and data produced increases significantly
Solution Approach 1:
The system performs preliminary actions by detecting the approach of the racing vehicle using a sensor device before the actual finish line crossing. This triggers the camera to start recording in advance, ensuring the vehicle is captured at the exact moment of crossing while minimizing unnecessary images of vehicles that have not yet approached the finish line.
Solution Approach 2:
The system dynamically adjusts the recording operation based on real-time detection. The camera recording is activated only when a vehicle is detected approaching the finish line by the sensor device, and deactivated when no vehicle is detected. This dynamic control optimizes the balance between capturing accurate racing events and minimizing data quantity.
2Reliability
If all images are recorded to ensure the racing event is captured, then the reliability of event detection is improved, but the complexity of image evaluation increases
Solution Approach 1:
The sensor device performs preliminary detection of the racing vehicle's approach and triggers the camera recording accordingly. This preliminary action ensures that the camera is actively recording only when a vehicle is approaching the finish line, guaranteeing that the racing event will be captured while avoiding the need to evaluate unnecessary images.
Solution Approach 2:
The system uses feedback from the sensor device to control the camera operation. The sensor continuously monitors the track and provides feedback signals to the camera control unit, which adjusts the recording operation in real-time. This feedback mechanism ensures reliable event detection while simplifying evaluation by eliminating images taken when no vehicle is present.
3Loss of information
If the camera records continuously to capture the finish line crossing, then the completeness of data is improved, but the time required for data evaluation increases
Solution Approach 1:
The sensor device detects the approach of the racing vehicle in advance and triggers the camera to start recording before the vehicle reaches the finish line. This preliminary action ensures that the complete racing event is captured without needing to evaluate continuous recordings, significantly reducing the time required for data evaluation while maintaining data completeness.
Solution Approach 2:
Instead of continuous recording, the system uses periodic action by activating the camera only during specific periods when a vehicle is detected approaching the finish line. The camera records in discrete intervals triggered by sensor detection, ensuring complete event capture while minimizing the total recording time and subsequent evaluation time.

AI summary
A device and a method for detecting, monitoring and/or controlling racing vehicles on a racetrack, having a camera for monitoring when a predetermined track section is crossed, a recording device for recording the images provided by the camera, a recording control device for automatically recording the images provided by the camera only during a specific time window within which the crossing of the track section, and a sensor device for detecting the crossing of the track section. A marking device generates a marking for a recorded image as a function of a sensor signal of the sensor device and the occurrence thereof in the specific time window. The marking is stored in an event list. An image of interest can be simply selected on the basis of the associated marking, without the images which are provided by the camera having to be evaluated themselves for this purpose.
