Vehicle Video Display Markers for Predicted Collision Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for displaying video images of an outside area of a moving body, such as vehicles, lack convenience and effectiveness in presenting relevant information to the driver, particularly in detecting and predicting the paths of objects within the vehicle's vicinity.
Innovation Solution
An image processing apparatus and display system that captures and processes video images from an imaging apparatus, detects objects, predicts their paths, and displays markers on a display apparatus to indicate potential collisions or important objects, enhancing the driver's awareness through dynamic overlay animations and improved visibility of critical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video images of outside areas are displayed on a monitor, then the driver can see the external environment, but the information presentation lacks convenience and effectiveness for detecting and predicting object paths
Solution Approach 1:
The patent applies color-coded markers (different colors indicating different collision risks or object types) to visually encode critical information about detected objects. This allows the driver to quickly assess situations based on color cues rather than analyzing raw video data, directly improving information presentation effectiveness while maintaining ease of operation through intuitive visual feedback.
Solution Approach 2:
The patent segments the video image by superimposing discrete markers on detected objects. This segmentation highlights specific elements of interest (objects, their paths, collision risks) separately from the background video feed, making critical information more salient and easier to process without overwhelming the driver with undifferentiated visual data.
2Measurement precision
If markers are superimposed on video images to indicate detected objects, then object detection capability is improved, but the complexity of the display system increases
Solution Approach 1:
The patent merges the video display function with the object detection and marker overlay functions into an integrated system. The marker generation and video rendering are combined in a single processing pipeline, where detected object data is directly overlaid on the corresponding video frames. This integration improves object detection presentation while managing system complexity through unified processing rather than separate independent systems.
Solution Approach 2:
The patent introduces markers as an intermediary visual element between the raw video feed and the driver's perception. These markers serve as a mediator that translates complex detection data (object position, velocity, collision risk) into simple, intuitive visual cues that can be quickly interpreted, improving detection capability while keeping the interface relatively simple.
3Loss of information
If multiple objects are detected and displayed, then comprehensive situational awareness is achieved, but the ability to prioritize critical information is reduced
Solution Approach 1:
The patent applies different visual properties (colors, marker styles, sizes) to different objects based on their local characteristics such as collision risk, distance, or type. This local differentiation allows the driver to quickly identify critical objects among multiple detected targets without needing to process each object uniformly, achieving comprehensive situational awareness while enabling easy prioritization through visual hierarchy.
Solution Approach 2:
The patent uses color-coded markers to encode different levels of urgency or object categories. By assigning specific colors to different risk levels or object types, the system enables the driver to instantly prioritize attention based on color cues, maintaining comprehensive situational awareness of all objects while facilitating rapid identification of critical threats among multiple detected targets.

AI summary
An image processing apparatus 30 includes a communication interface 31 and a controller 33. The communication interface 31 is configured to acquire a first video image capturing an outside area of a moving body 50. The controller 33 is configured to cause a second video image corresponding to a display region 62 of the first video image to be displayed on a display apparatus 40. The controller 33 is also configured to detect at least a portion of a detection object in the display region 62 of the first video image, determine whether one or more conditions are met based on a relative positional relationship between the moving body 50 and the detection object and, when it is determined that the one or more conditions are met, cause a first marker 71 corresponding to the detection object to be superimposed on the second video image and displayed on the display apparatus 40.
