AI Technical Summary

Technical Problem

Existing systems that capture and display the surroundings of a vehicle using an onboard camera do not effectively provide location information of surrounding objects, limiting user understanding of their positions.

Method used

A display system that calculates the horizontal relative position of objects in captured images using the Earth's radius and image capture device height, corrects for orientation changes, and plots positions on a two-dimensional coordinate system, allowing for trajectory display on two- and three-dimensional coordinates.

Benefits of technology

Enables accurate presentation of surrounding object positions and trajectories, even when objects are temporarily hidden or outside the camera's view, by interpolating and correcting for orientation and position changes.

Abstract

To make it possible to present positional information on surrounding objects based on captured images of the surroundings.SOLUTION: A display system includes: a photographing device that photographs; a position calculation unit that calculates a relative position in a horizontal direction relative to a reference position of an object whose image is included in an image captured by the photographing device; and a display unit that displays an image in which the position of the object is plotted on two-dimensional coordinates in which an intersection of coordinate axes indicates the reference position.SELECTED DRAWING: Figure 1
