Samsung patents rail vehicle alignment using QR codes
Samsung has been granted a patent for a method that helps automated vehicles on rails align precisely with loading spots. The system compares images of QR codes at different stops to calculate the exact position needed for accurate docking.
In the filing’s own words
In a teaching method, a vehicle, which travels along a traveling rail, is allowed to arrive at a reference loading/unloading position adjacent to a reference seating surface having a reference QR code displayed thereon. A first image corresponding to the reference seating surface is acquired at the reference loading/unloading position. The vehicle, which further travels along the traveling rail, is allowed to arrive at a target loading/unloading position adjacent to the target seating surface having a target QR code displayed thereon. A second image corresponding to the target seating surface is acquired at the target loading/unloading position. The first image and the second image are compared with each other to acquire n X-axial directional teaching relative value and a Y-axis directional teaching relative value.
What exactly they claim (claim 1)
1. A teaching method, comprising: allowing a vehicle, which travels along a traveling rail, to arrive at a reference loading/unloading position that is adjacent to a reference seating surface having a reference QR code displayed thereon; acquiring a first image corresponding to the reference seating surface at the reference loading/unloading position; allowing the vehicle, which further travels along the traveling rail, to arrive at a target loading/unloading position that is adjacent to a target seating surface having a target QR code displayed thereon; acquiring a second image corresponding to the target seating surface at the target loading/unloading position; comparing the first image with the second image to acquire an X-axis directional teaching relative value and a Y-axis directional teaching relative value; and determining a Y-axis directional target teaching value based on the Y-axis directional teaching relative value and correcting the Y-axis directional target teaching value using correction data collected at the target loading/unloading position, wherein the correction data includes tilt data, and wherein the tilt data includes a Y-axis directional target tilting angle collected by a gradient sensor.
