Vehicle Camera Image Processing with Distortion-Corrected Reference Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wide-angle cameras mounted on vehicles capture images with significant distortion, making it difficult for drivers to accurately determine distances and directions, especially when reversing or navigating through poor visibility conditions.
Innovation Solution
An image processing device that superimposes reference lines and guidelines onto the captured image, correcting for distortion by using a controller to read and display distance information from stored coordinates, allowing drivers to discern distances and directions more accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wide-angle camera is used to capture image, then the field of view is widened and the driver can visually confirm a wider range, but the image becomes distorted gradually from the center towards the outer edges
Solution Approach 1:
The patent introduces reference lines as an intermediary element between the distorted wide-angle image and the driver's perception. These reference lines are superimposed on the image to provide visual cues that help the driver correctly interpret distances and directions despite the optical distortion caused by the wide-angle lens
Solution Approach 2:
The patent changes the visual parameters of the display by superimposing reference lines with specific positional and directional characteristics. These reference lines are positioned and oriented to compensate for the distortion parameters of the wide-angle lens, effectively correcting the perceived distance and direction without changing the underlying image
2Area of stationary object
If wide-angle capturing is used, then the driver can see a wider range on one screen, but the driver cannot easily discern the distance between the car and another object
Solution Approach 1:
Reference lines are introduced as visual intermediaries that carry distance information. By positioning these reference lines at specific distances from the vehicle and displaying them on the screen, the system provides the driver with intuitive visual cues about distance that are otherwise lost in the distorted wide-angle image
3Area of stationary object
If wide-angle capturing is used, then the driver can see a wider range on one screen, but the driver cannot easily discern the direction of another object with reference to the travelling direction of the car
Solution Approach 1:
The reference lines serve as directional intermediaries that are oriented to reflect the actual spatial relationships in the environment. By aligning these reference lines with the true directional information and superimposing them on the distorted image, the system provides the driver with accurate directional cues that counteract the distortion effects

AI summary
An image processing device, an image processing method, and an image display system allow a driver to obtain a sense of direction and a sense of distance with wide-angle image captured by a car-mounted camera. An image processing device (40) for superimposing predetermined information on image captured by a camera (12) that attaches to a vehicle (100) and is capable of wide-angle capturing in a travelling direction of the vehicle (100) includes a controller (14) that performs control to superimpose information upon detecting, in a state of outputting image captured by the camera (12), input indicating a predetermined position in the image, the information relating to a distance between the vehicle (100) and the position indicated in the image captured by the camera (12).
