Motion state of impacting and impacted object measuring apparatus and method

摘要

A measurement apparatus includes a first Doppler sensor which outputs a first transmission signal and receives a first Doppler signal, that is the first transmission signal returned after being reflected by an impacting object, a timing detection unit that detects an impact timing which is a moment when an impacted object is impacted by the impacting object, an impacting object speed computing unit that computes a speed of the impacting object based on the first Doppler signals obtained from the detected impact timing to a timing before a predetermined period, and an imaging unit that images the impacted object immediately after the impact so as to be used for computing a motion state of the impacted object, based on the computed speed of the impacting object.

1. A measurement apparatus comprising:
a first Doppler sensor which outputs a first transmission signal and receives a first Doppler signal, that is the first transmission signal returned after being reflected by an impacting object; an impact timing detection unit that detects an impact timing, that is a moment when an impacted object is impacted by the impacting object; an impacting object speed computing unit that computes a speed of the impacting object based on the first Doppler signals obtained between the detected impact timing and a previous timing before a predetermined period; an image timing determination unit that determines a first imaging timing and a second imaging timing that capture images, based on the computed speed of the impacting object; and an imaging unit that capture the images that contain the impacted object immediately after the impact and is used for computing a motion state of the impacted object, according to the determined imaging timings.
