Title:
THREE-DIMENSIONAL MOTION ACQUISITION DEVICE AND THREE-DIMENSIONAL MOTION ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/142878
Kind Code:
A1
Abstract:
This three-dimensional motion acquisition device (1) is provided with: a light source (110); a charge amount acquisition circuit (120) that includes a plurality of pixels and acquires, for each pixel, a first charge amount for a first exposure pattern and a second charge amount for a second exposure pattern having at least partial exposure period overlap with the first exposure pattern; and a processor (130) for controlling the light emission pattern of the light source (110), first exposure pattern, and second exposure pattern. The processor (130) estimates the distance to a subject for each pixel on the basis of the light emission pattern and the first charge amount and second charge amount for the pixel that have been acquired by the charge amount acquisition circuit (120) and estimates the optical flow for each pixel on the basis of the first exposure pattern, the second exposure pattern, and the first charge amount and second charge amount acquired by the charge amount acquisition circuit (120).
