Title:
AIMING DEVICE, DRIVE CONTROL SYSTEM, AND METHOD FOR CALCULATING CORRECTION AMOUNT OF SENSOR DATA
Document Type and Number:
WIPO Patent Application WO/2021/024712
Kind Code:
A1
Abstract:
The present invention corrects axial misalignment of a sensor. This aiming device uses sensing results of two or more sensors to calculate correction amounts of the sensing results from the sensors, and is provided with: a sensor coordinate conversion unit for converting sensor data sets that are detected by the respective sensors and that are in coordinate systems unique to the respective sensors into data sets in a prescribed standardized coordinate system; a target selection unit which selects prescribed terrestrial objects from the sensor data sets detected by the respective sensors; a function fitting unit which determines, for each of the sensors, a function that approximates an arrangement state of the selected terrestrial objects; a fitting result comparison unit which compares the functions approximating the arrangement states of the terrestrial objects detected by the respective sensors; and a correction value calculation unit which, on the basis of the result of comparison of the functions, calculates a correction amount for converting the coordinates of the terrestrial objects detected by the sensors.
