Transparent Display Target Position Estimation for Extended Information Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent displays on vehicles have a short information display time as they require external image circuits to identify targets within the user's visual range, leading to inefficient information presentation, especially when the target is moving relative to the vehicle.
Innovation Solution
A system comprising a transparent display, an external image circuit, a speed sensing apparatus, and a processor that captures images of targets, estimates their position and time of appearance in the display region, and displays prompting information accordingly, allowing for pre-identification and extended information display time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the external image circuit identifies the target only when it enters the user's visual range, then the system structure remains simple, but the information display time becomes extremely short
Solution Approach 1:
The system performs preliminary target identification and information preparation before the target enters the user's visual range. The external image circuit captures images of targets in advance, the processor identifies them and determines relevant information, and the transparent display prepares to show this information as soon as the target enters the visual range, thereby extending the effective display time without significantly increasing system complexity
Solution Approach 2:
The system divides the target processing into multiple stages: pre-identification stage (when target is outside visual range), active display stage (when target enters visual range), and post-processing stage. This segmentation allows the system to prepare information in advance and display it efficiently, improving the overall information display duration while maintaining manageable system complexity through modular processing
2Loss of time
If the external image circuit is mounted within the visual range of the user, then the system structure is simple, but the target identification time is extended resulting in short information display time
Solution Approach 1:
The external image circuit is positioned outside the user's visual range to perform preliminary target identification and capture imaging in advance. This allows the processor to identify targets and determine relevant information before they enter the visual range, eliminating identification delay during the critical display period and maximizing information display time without compromising identification accuracy
3Duration of action of moving object
If the system waits for the target to enter the visual range before displaying information, then the display accuracy is high, but the information display duration is extremely short
Solution Approach 1:
The system performs preliminary identification and information determination before the target enters the visual range. The processor identifies the target, determines relevant information, and prepares the display content in advance. When the target enters the visual range, the information is immediately displayed, ensuring both complete information presentation and extended display duration
Solution Approach 2:
The system continuously monitors the target's position and movement, providing feedback to the display control. Based on this feedback, the system adjusts the display timing and content to ensure information is displayed at the optimal moment and maintained for the maximum duration while the target remains in the visual range, preventing information loss

AI summary
The present disclosure provides a method and system of displaying information, applied to a transparent display configured on a vehicle. The method includes: capturing an image including a target at a first time point; identifying the target in the image, so as to acquire a first relative position of the target; acquiring first identification information of the target; acquiring relative moving information between the vehicle and the target; estimating a first estimated position and first estimated time of the target that appears in a display region of the transparent display according to the first relative position of the target, the first time point and the relative moving information; and displaying prompting information corresponding to the target on the transparent display according to the first estimated time, the first estimated position of the target and the first identification information of the target.
