摘要：PROBLEM TO BE SOLVED: To calibrate external parameters with high accuracyeven when a surrounding road surface is composed of a plurality of planes. A calibrationdevice is extracted by a camera mounted on a vehicle traveling on a road surface, afeature point extraction unit that extracts feature points from a captured image taken by

the camera, and a feature point extraction unit. It was estimated to be a tracking unit thattracks the feature points, a storage unit that stores the trajectory of the feature pointsobtained by tracking the feature points, and a road surface estimation unit that estimatesthe plane on which the vehicle travels using the trajectory of the feature points. Itincludes a calculation unit that calculates a calibration locus, which is a locus of featurepoints used for calibration based on a plane, and an external parameter estimation unitthat executes calibration of external parameters of the camera using the calibrationlocus.
