Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object detection methods in mobile environments with high-resolution images require excessive computations, making real-time object detection challenging due to the need to search the entire image for objects, regardless of their likelihood of presence in specific areas.
Innovation Solution
A method and apparatus that limit the object detection area using sensor information such as 3-axis angular velocity, steering information, and motion vectors to focus detection on areas where new objects are likely to appear, reducing unnecessary computations and improving processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the whole image is searched for object detection, then all objects in the image can be detected, but unnecessary computations are introduced and detection time increases
Solution Approach 1:
The patent divides the image into multiple regions based on sensor information (rotation angle, position data) and processes each region separately. This segmentation allows the system to focus computational resources only on areas where objects are likely to appear, rather than processing the entire image, thus reducing detection time while maintaining accuracy.
Solution Approach 2:
The patent applies different processing strategies to different regions of the image based on local characteristics determined by sensor data. High-priority regions (where objects are more likely to appear based on rotation and position) receive full detection processing, while other regions receive reduced or no processing, optimizing the balance between detection accuracy and processing time.
2Measurement precision
If high-resolution images are processed, then detection accuracy improves, but the amount of computation increases making real-time detection difficult in mobile environments
Solution Approach 1:
The patent extracts and utilizes sensor information (rotation detection sensor data, position sensor data) to identify and extract only the relevant regions from high-resolution images that contain potential objects. By taking out and processing only these extracted regions rather than the entire high-resolution image, the system maintains detection accuracy while significantly reducing computational load for real-time processing in mobile environments.
Solution Approach 2:
The patent performs partial action by processing only the necessary portions of the image (regions identified through sensor fusion) rather than the complete image. This partial processing approach provides sufficient detection accuracy for practical applications while reducing computation time to enable real-time performance on mobile devices with limited processing power.

AI summary
Provided are a method for limiting an object detection area in a mobile system equipped with an image sensor and an apparatus for performing the method. The method comprises receiving an image obtained with respect to a detection target object from the image sensor and receiving sensor information from a rotation detection sensor only when the mobile system is equipped with the rotation detection sensor—the sensor information includes at least one of 3-axis angular velocity and steering information, wherein the steering information includes a steering angle and a speed; determining rotation of the mobile system by using at least one of the sensor information and motion vectors; and if it is determined that the mobile system is rotating, limiting an object detection area by using at least one of the sensor information and the motion vectors.
