TIME-TO-COLLISION CALCULATION DEVICE AND COLLISION AVOIDANCE SYSTEM

摘要

An attenuation unit in this time-to-collision calculation device determines whether time-series data created by a time-series data creation unit is based on at least a part of a target recognized by use of a whole-body dictionary or on at least a part of a target acknowledged by use of a parts dictionary, determines, on the basis of the determination result, a frequency range in which the time-series data created by the time-series data creation unit is to be attenuated, and attenuates data, among the time-series data, which is within the determined frequency range.
