Vehicle Obstacle Detection Relay System with Confidence Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information collection systems for vehicles face increased processing load and data volume when identifying road obstacles through image processing, as they receive and process extensive image information from multiple vehicles.
Innovation Solution
An information collection system comprising a control device on each vehicle, a relay device, and a collection device, where the control device calculates the confidence of obstacle presence in captured images and transmits image information, position, and confidence levels to the relay device, which performs image processing in decreasing order of confidence and converts image data into text information, reducing the information load on the collection device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed on all captured images transmitted from the vehicle side to identify road obstacles, then obstacle identification accuracy is improved, but the processing load on the information processing apparatus is increased
Solution Approach 1:
The system performs preliminary filtering by transmitting only image data that meets specific transmission conditions (such as detecting potential obstacles or abnormal situations) rather than processing all captured images. This preliminary selection reduces the volume of data requiring intensive image processing while maintaining obstacle identification accuracy for relevant cases
Solution Approach 2:
The system extracts and transmits only specific image data that contains potential obstacle information based on predetermined conditions, separating relevant data from irrelevant data. This extraction process eliminates unnecessary image processing for non-critical images, thereby reducing the processing load on the information processing apparatus
2Reliability
If extensive image information is transmitted from multiple vehicles to the collection device, then comprehensive obstacle detection coverage is improved, but the information load and data volume are increased
Solution Approach 1:
The system applies different data transmission qualities to different vehicles or different image data based on local conditions. Image data from vehicles or situations with higher obstacle risk or better detection quality are transmitted with higher priority or detail, while other data are transmitted with reduced detail or aggregated, thereby maintaining comprehensive coverage while reducing overall information load
Solution Approach 2:
The system transmits image data selectively based on predetermined conditions rather than transmitting all possible data. By applying partial action (transmitting only when conditions are met), the system achieves sufficient obstacle detection coverage without the excessive information load of transmitting all captured images from all vehicles

AI summary
An information collection system includes a control device installed at a vehicle, a collection device that collects obstacle information from a plurality of the control devices, and a relay device that relays communications between the control device and the collection device. A first processor of the control device calculates a degree of confidence that an obstacle as included in a captured image captured by an image capture device provided at the vehicle, and transmits image information related to the captured image, position information added to the captured image, and the degree of confidence, to the relay device. A second processor of the relay device receives the image information, the position information, and the degree of confidence, from the control devices, and identifies an obstacle included in a captured image according to the image information in descending order of the degree of confidence. If an obstacle has been identified, the second processor transmits text information relating to the position of the identified obstacle and the content of the identified obstacle to the collection device. A third processor of the collection device receives the text information from one or more of the relay devices and stores the text information corresponding to the identified obstacle.
