In-Vehicle Image Transmission Selective Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traveling guidance systems lack an efficient method for collecting data of mark target candidates at intersections, particularly where data collection is not necessary, leading to unnecessary data transmission and storage.
Innovation Solution
A non-transitory storage medium and image transmission method that uses an in-vehicle device with an imaging unit and communication unit to acquire and transmit images of intersections based on whether a mark target is prominent, referencing a database to determine prominence and restrict image acquisition to specific positions and conditions, thereby reducing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If images are collected at all intersections, then data completeness is improved, but data transmission volume and storage requirements increase
Solution Approach 1:
The patent applies local quality by differentiating image collection strategies based on intersection characteristics. Prominent mark targets (e.g., well-known landmarks, major facilities) are identified through database matching, and image collection is selectively performed only at intersections where such prominent targets are absent. This creates a non-uniform data collection approach where each intersection is treated according to its specific characteristics rather than applying a blanket collection policy, thereby reducing overall data volume while maintaining information completeness for navigation purposes.
Solution Approach 2:
The patent implements partial action by performing image collection only when necessary - specifically at intersections lacking prominent mark targets. Rather than collecting images at all intersections (excessive action), the system selectively collects images only where they provide additional navigational value. This partial approach reduces data transmission volume and storage requirements while still ensuring that sufficient landmark information is available for effective navigation guidance.
2Measurement precision
If images are transmitted to information center, then navigation accuracy is improved, but communication bandwidth consumption increases
Solution Approach 1:
The system applies local quality by transmitting image data selectively based on the specific characteristics of each intersection. Instead of uniformly transmitting all captured images to the information center, the system identifies intersections where prominent mark targets are absent and transmits images only for those locations. This targeted transmission approach maintains navigation accuracy by ensuring critical landmark data is available while significantly reducing communication bandwidth consumption compared to universal image transmission.
3Measurement precision
If all mark target candidates are collected, then mark selection accuracy is improved, but data processing time increases
Solution Approach 1:
The patent applies the extraction principle by removing unnecessary data collection steps. Instead of collecting and processing images at all intersections, the system extracts only the essential information by checking database records for prominent mark targets and collecting images only when such targets are absent. This extraction approach maintains mark selection accuracy by ensuring relevant landmark data is captured while reducing data processing time by eliminating redundant collection and processing operations at intersections where prominent targets already exist.

AI summary
A non-transitory storage medium storing an image transmission program that is executed on an in-vehicle device mounted in a vehicle having an imaging unit configured to image surroundings of the vehicle to acquire an image and a communication unit configured to perform communication with an information center, the image transmission program includes: an image acquisition step of causing the imaging unit to acquire an image relating to an intersection based on whether or not a mark target facing the intersection is prominent; and a transmission step of causing the communication unit to transmit the image acquired to the information center.
