Dashboard Camera Relay Imaging via Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dashboard camera systems are limited in capturing images over a wide range due to fixed-angle cameras, leading to increased costs and complexity when using omnidirectional cameras for broader coverage.
Innovation Solution
A communication system comprising a first imaging device, a communication unit for relay communication between a mobile communication terminal and a communication device, and an image processing unit that synchronizes and integrates images from both devices to provide comprehensive coverage at a lower cost.

1Area of stationary object
If a fixed-angle camera is used in the dashboard camera recorder, then the device cost and complexity are low, but the image collection range is limited
Solution Approach 1:
The imaging function is segmented between the dashboard camera recorder's fixed-angle camera and the mobile communication terminal's imaging device. The dashboard camera recorder collects images from a fixed angle, while the mobile terminal captures images from various angles, together achieving wide-area coverage without requiring an omnidirectional camera in the dashboard device.
Solution Approach 2:
The mobile communication terminal acts as an intermediary device that extends the imaging capability. It receives control signals from the dashboard camera recorder, captures images from multiple angles using its own imaging device, and transmits these images back to the dashboard camera recorder, effectively mediating the expansion of image collection range.
2Area of stationary object
If an omnidirectional camera is used to capture images from various angles, then the image collection range is wide, but the device cost and image processing complexity increase
Solution Approach 1:
The imaging function is segmented between the dashboard camera recorder's fixed-angle camera and the mobile communication terminal's imaging device. The dashboard camera recorder collects images from a fixed angle, while the mobile terminal captures images from various angles, together achieving wide-area coverage without requiring an omnidirectional camera in the dashboard device.
Solution Approach 2:
Instead of using an expensive omnidirectional camera in the dashboard recorder, the system uses a standard camera in the mobile terminal to capture images from various angles. The mobile terminal's camera serves as a copy or extension of the imaging function, providing multi-angle coverage at lower cost.
3Area of stationary object
If images are captured by multiple devices at different times, then comprehensive coverage is achieved, but synchronization and processing complexity increases
Solution Approach 1:
The dashboard camera recorder determines synchronous imaging time points in advance and transmits this timing information to the mobile communication terminal. Both devices then capture images at these predetermined synchronized moments, eliminating the need for complex post-capture synchronization and reducing processing complexity.
