Predicted Image Generation for Wireless Communication Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delays in wireless communication between onboard and terminal apparatuses can result in the presentation of captured images at past times, making it difficult to provide real-time information about the vehicle's surroundings.
Innovation Solution
Generating and presenting a predicted image based on the captured image and vehicle state information, accounting for the delay time in wireless communication, to ensure real-time representation of the vehicle's environment.

1Reliability
If captured images are transmitted via wireless communication between onboard and terminal apparatuses, then image information can be presented on the terminal apparatus, but communication delay causes the presented image to be from past time rather than real-time
Solution Approach 1:
The system performs preliminary actions by calculating the delay time in advance and using this information to select and present appropriate images. The terminal apparatus predicts what the current image should look like based on the delay characteristics of the communication channel, rather than simply displaying the most recently received image.
Solution Approach 2:
The system implements feedback by using the known delay time to adjust image presentation. The terminal apparatus receives information about communication delay and uses this feedback to compensate for the delay effect, selecting images that represent the current real-time state rather than past states.
2Productivity
If the terminal apparatus presents the most recently received captured image, then the image transmission is simple, but the presented image does not represent the current real-time state due to communication delay
Solution Approach 1:
The system calculates the delay time in advance and uses this pre-computed information to guide image selection. By knowing the delay characteristics beforehand, the terminal apparatus can directly select the appropriate image without complex real-time adjustments, maintaining high presentation speed while improving timing accuracy.

AI summary
An information presentation system (1000) comprising a control device (10) is provided. The control device (10) executes an image acquisition function to acquire a captured image around a vehicle captured by an onboard camera (1), a delay state determination function to determine a delay state using a delay time of wireless communication between an onboard apparatus (200) and a terminal apparatus (100), a predicted image generation function to calculate a position of the vehicle after the delay time on a basis of state information of the vehicle and generate a predicted image using the captured image that has been acquired so as to predict the predicted image to be captured by the camera (1) at the calculated position of the vehicle, , and a presentation function to present the predicted image.
