Video Trajectory Display with Time-Weighted Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video image analysis techniques fail to efficiently display object features from past images while monitoring current video, leading to increased time costs and oversight risks, as they do not effectively show recent and current behaviors, surrounding situations, and feature changes of objects.
Innovation Solution
A video image processing device and system that displays a trajectory indicating a change in an object's position, with varying display modes and attached information based on object features and elapsed time, allowing for quick grasping of object situations at multiple points in time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If movement trajectory is simply superimposed on current image, then movement path can be observed, but recent and current behaviors, surrounding situations, and feature changes cannot be known
Solution Approach 1:
The trajectory is divided into multiple segments corresponding to different time periods (e.g., recent past, older past). Each segment can be displayed with different visual characteristics or information overlays, allowing operators to see both historical path and recent behaviors without information overload.
Solution Approach 2:
Different portions of the trajectory display different types of information or visual styles. For example, recent trajectory segments may show detailed feature changes while older segments show only positional information. This allows critical information to be highlighted without complicating the entire display.
2Loss of information
If multiple video images are checked to gather object features, then comprehensive information can be obtained, but time costs increase
Solution Approach 1:
Multiple video images and trajectory information are merged into a single composite display. The trajectory overlay integrates positional history with current image context, while feature change information is叠加 on relevant trajectory segments, eliminating the need to switch between multiple screens or video windows.
Solution Approach 2:
The system pre-processes and pre-displays trajectory information and feature changes along the object's path. When an operator views the current image, relevant historical information is already prepared and displayed on the trajectory, eliminating the need for operators to manually check multiple past video frames.
3Loss of information
If trajectory information is displayed without time differentiation, then simple movement path is shown, but elapsed time and recent behaviors cannot be understood
Solution Approach 1:
Different time periods or movement phases are represented by different colors or shades along the trajectory. For example, recent trajectory segments may be displayed in bright colors while older segments use darker shades, and feature change events are marked with distinct color indicators, making time and behavior information immediately visible.
Solution Approach 2:
The trajectory display is dynamic and updates in real-time as new video images are processed. Recent trajectory segments are continuously added or highlighted, while older segments may be faded or summarized. This dynamic presentation adapts to the current situation and emphasizes temporally relevant information.

AI summary
A video image processing device according to the present invention includes a display control means (501) that causes a display unit to display a trajectory indicating a change in the position of an object in a video image. The display control means (501) makes the display mode of a part of the trajectory differ from another part or attach information indicating an analysis result or an elapsed time to the vicinity of a part of the trajectory, in accordance with a feature of the object shown in the analysis result obtained as a result of analysis of the video image, a feature of another object related to the object shown in the analysis result, or the time elapsed since a predetermined time.
