Adaptive Vehicle Camera Selection for Image Processor Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems with multiple camera units overload the image-processing unit due to the increased computational requirements, as all cameras are simultaneously processing image data, leading to potential processing capacity issues.
Innovation Solution
An adaptive camera system with multiple camera arrangements, each having distinct optical properties such as different fields of view and spectral responses, selectively connects only the preferred camera arrangement to the image processor based on vehicle driving status data, reducing the computational load.

Engineering Contradiction Analysis
1Reliability
If all camera units are simultaneously connected to the image processor, then complete coverage of all fields of view is achieved, but the image processor becomes overloaded due to increased computational requirements
Solution Approach 1:
The camera arrangement selection unit dynamically selects which camera arrangements are connected to the image processor based on current driving status. The system transitions from a static configuration where all cameras are always connected to a dynamic configuration where connections are adaptively established or disconnected based on real-time driving conditions, thereby optimizing the balance between field of view coverage and processing load.
Solution Approach 2:
The system changes the operational parameter of camera arrangement connectivity based on driving status. By modifying which camera arrangements are actively connected to the image processor according to driving conditions (such as speed, direction, or environmental factors), the system adapts the processing load to match actual operational requirements, preventing overload while maintaining necessary surveillance coverage.
2Area of stationary object
If the number of camera units is increased, then the field of view coverage is improved, but the computational power required for processing increases
Solution Approach 1:
The system extracts only the necessary camera arrangements from the complete set of available cameras and connects them to the image processor based on current driving status. By selectively taking out and activating only the relevant camera arrangements needed for the current driving condition, the system maintains comprehensive field of view coverage when necessary while reducing computational power consumption when full coverage is not required.
3Productivity
If processing capacity of the image processor is increased, then the system can handle more camera units, but the system cost increases
Solution Approach 1:
Instead of providing full processing capacity for all camera units simultaneously, the system applies partial action by activating processing capacity only for the subset of camera arrangements that are currently needed based on driving status. This approach avoids the excessive cost of provisioning processing power for all possible camera configurations, while still maintaining the ability to handle complete coverage when required.

AI summary
An adaptive camera system for a vehicle, including a plurality of camera arrangements each including at least one camera unit, wherein each camera arrangement is arranged on the vehicle and configured to have respective different optical properties to cover a respective different field of view and/or to have a respective different spectral response. The plurality of camera arrangements are adapted to be connected in data-communication to an image processor configured to receive image data from the camera arrangement. The system further includes a camera arrangement selector configured to receive driving-status data pertaining to an actual status of the vehicle. The camera arrangement selector is adapted to select from the plurality of camera arrangements, using the driving-status data, at least one preferred camera arrangement for being connected in data-communication to the image processor. A data-communication connection to the image processor is restricted to the at least one preferred camera arrangement.
