MEASUREMENT DEVICE, MEASUREMENT METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/112532
Kind Code:
A1
Abstract:
This measurement device comprises a vision sensor having a plurality of pixels that output event signals in an asynchronous manner according to a change of the luminance of incident light, a cluster forming unit that forms a point group of events caused by the same target particle, as a cluster on the basis of the event signals inputted in a predetermined period, a feature value calculating unit that calculates the feature value of the cluster, and a cluster classifying unit that classifies the cluster on the basis of the feature value calculated by the feature value calculating unit.
