Title:
VEHICLE-MOUNTED IMAGE PROCESSING DEVICE AND CALIBRATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/199465
Kind Code:
A1
Abstract:
The present invention optimizes the implementation timing of calibration and limits the stoppage period of ADAS. The present invention is a vehicle-mounted image processing device that is mounted in a vehicle and processes an exterior image acquired by a camera, wherein the device includes: a temperature sensor that detects the current temperature; a temperature predicting unit that predicts a future temperature on the basis of time sequence data of temperatures; a distance measurement error predicting unit that predicts a future distance measurement error on the basis of the temperature prediction; a calibration timing determining unit that determines a timing at which calibration using the image can be implemented, on the basis of vehicle operation information or external world recognition information; and a calibration start determining unit that, when the calibration timing determining unit has determined that the calibration can be implemented in a remaining time until the point in time that the distance measurement error predicted by the distance measurement error predicting unit is predicted to exceed a threshold, evaluates whether or not to start the calibration using the image, on the basis of the current temperature or the remaining time.
