Drive Recorder With Speed-Adaptive Landmark Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult for a vehicle driver to shoot photographs of landmarks while the vehicle is traveling, as it requires stopping and getting out of the vehicle, which can interfere with driving.
Innovation Solution
A drive recorder with a camera and processing device that recognizes landmarks in the image, sets shutter speed and shooting timing based on vehicle speed, and automatically captures photographs at optimal times while the vehicle is moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the driver stops the vehicle to photograph landmarks, then the photograph quality improves, but the driving efficiency deteriorates
Solution Approach 1:
The drive recorder system automatically detects landmarks, determines optimal shooting positions, and captures photographs without requiring driver intervention. The system serves itself by using its own camera and processing capabilities to identify landmarks and execute photography, thereby maintaining driving efficiency while achieving good photograph quality.
Solution Approach 2:
The system performs preliminary detection of landmarks and pre-calculates optimal shooting positions and timing before the vehicle reaches the landmark. By preparing the shooting parameters in advance based on vehicle speed and landmark position, the system ensures ready-to-execute photography when the optimal moment arrives, eliminating the need for stopping.
2Adaptability or versatility
If the driver manually operates the camera to photograph landmarks, then the shooting flexibility improves, but the operation complexity increases
Solution Approach 1:
The drive recorder system autonomously performs landmark detection, shooting timing determination, and photograph capture without requiring driver operation. The system uses its embedded camera and processing device to automatically identify landmarks and execute photography, thereby reducing operation complexity to zero while maintaining adaptability through automated landmark recognition.
3Productivity
If the vehicle travels at high speed, then the driving efficiency improves, but the photograph quality deteriorates due to motion blur
Solution Approach 1:
The system dynamically adjusts the shutter speed based on the vehicle's current speed to compensate for motion blur. When the vehicle travels at high speed, the shutter speed is shortened to freeze motion, while at lower speeds, a longer shutter speed can be used. This dynamic adjustment maintains photograph quality across varying driving conditions without requiring speed reduction.
Solution Approach 2:
The system changes the shutter speed parameter according to vehicle speed to maintain photograph quality. By adjusting this critical photography parameter in real-time based on driving conditions, the system enables high-speed travel while preventing motion blur from degrading image quality.

AI summary
A drive recorder mounted on a vehicle includes a camera and a processing device. When the processing device recognizes that a landmark appears in the image shot by the camera, the processing device performs a process of setting the shutter speed and shooting timing for taking a photo of the landmark based on the vehicle speed, and A process of shooting a landmark at the shutter speed and shooting timing is executed.
