AI Technical Summary

Technical Problem

The prior art fails to fully consider the position accuracy of the identification part when using augmented reality (AR) machines, resulting in the inability to accurately measure the installation position when the camera and the identification part are far apart, and the relative position accuracy is low, which in turn affects the calculation accuracy of the installation position.

Method used

By setting multiple reference points in the real space, determining the distance between them, using a camera to capture images containing vehicles, establishing virtual spaces, and integrating these spaces in the virtual world space, calculating the vehicle centerline, and then determining the installation position of the target device used to adjust the vehicle sensors, and displaying installation position information in the image or operator's field of view.

Benefits of technology

The accuracy of the installation position of the vehicle adjustment equipment target device is improved, the error and labor hours of manual measurement are reduced, and the installation efficiency and accuracy are improved.

Abstract

To accurately identify an installation position of a target used for aiming a vehicle.SOLUTION: An installation position information providing method captures a video including a vehicle arranged in real space by a camera, sets first virtual space using a first reference point of a plurality of reference points as an original point to position a position of a first predetermined portion of the vehicle in the first virtual space, sets second virtual space using a second reference point of the plurality of reference points as an original point to position a position of a second predetermined portion of the vehicle in the second virtual space, integrates the first virtual space and the second virtual space into virtual world space, sets a center line of the vehicle on the basis of the position of the first predetermined portion and the position of the second predetermined portion in the virtual world space, calculates an installation position of a target used for adjusting a sensor mounted on the vehicle on the basis of the center line, and displays information indicating the installation position of the target by superimposing the information on the video captured by the camera or a field of view of an operator.SELECTED DRAWING: Figure 9
