Adjustable Camera Around View System for Vehicle Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional around view provision systems for vehicles are limited in their ability to capture blind spots that cannot be observed by side or rear view mirrors, increasing the risk of accidents during vehicle operation.
Innovation Solution
An around view provision apparatus equipped with direction-adjustable cameras that can be operated in different modes to capture blind spots when the vehicle is moving forward at a certain speed, and a processor that combines images from multiple cameras to generate an around view image, allowing for enhanced visibility of the vehicle's surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional side view and rear view mirrors are used, then the structure is simple, but blind spots cannot be observed
Solution Approach 1:
The patent combines multiple cameras (front, rear, left side, right side) into an integrated around view provision system that captures images from multiple positions simultaneously. The processor merges these images to generate a comprehensive around view image, eliminating blind spots while maintaining manageable system complexity through coordinated operation of the camera array
Solution Approach 2:
The system transitions from two-dimensional mirror reflection to multi-dimensional image capture by positioning cameras at four different locations around the vehicle (front, rear, left, right). This spatial distribution across multiple dimensions enables complete coverage of areas that would be invisible to traditional mirrors
2Reliability
If direction-adjustable cameras are used to capture blind spots, then observation coverage is improved, but device complexity increases
Solution Approach 1:
The camera mounting structure incorporates rotational and tilting capabilities that allow the cameras to dynamically adjust their observation directions. The processor controls these directional adjustments based on vehicle state (moving forward or backward), enabling the system to adaptively capture blind spots while managing complexity through automated control
Solution Approach 2:
The processor receives vehicle state information (forward or backward movement) and uses this feedback to automatically adjust camera directions and select appropriate observation modes. This closed-loop control eliminates the need for manual adjustment while ensuring optimal blind spot coverage for each driving condition
3Reliability
If multiple cameras are used to generate around view image, then visibility is enhanced, but image processing complexity increases
Solution Approach 1:
The system divides the around view into four distinct image regions, each captured by a dedicated camera (front, rear, left side, right side). The processor segments the processing task by assigning each camera's image data to a specific region, then combines these segmented regions into a complete around view image, simplifying the overall processing complexity through modular handling

AI summary
An around view provision apparatus and a vehicle including the same may include at least one camera mounted on a vehicle, a direction of the at least one camera being adjustable, and a processor to control the at least one camera to capture images around the vehicle based on a movement of the vehicle. The camera may be controlled to operate in a first mode when the vehicle is moving forward at a first prescribed speed or more and in a second mode when the vehicle is moving forward at less than a second prescribed speed or is moving backward. In the first mode, the camera may capture a lateral region that cannot be observed through a side view mirror or a rear view mirror. In the second mode, the camera may capture a larger region that is angled downward relative to the lateral region in the first mode.
