Title:
WEARABLE DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/184100
Kind Code:
A1
Abstract:
Provided is a wearable device capable of realizing highly accurate work assistance without reducing workability. This wearable device is provided with: an imaging unit that generates image data; a control unit that sets a projection condition on the basis of the image data; and a projection unit that projects light in accordance with the projection condition. The control unit sets a first projection condition for projecting detection light for forming a prescribed pattern, acquires a first image captured when the detection light is not applied and a second image captured when the detection light is applied, sets a first region on the basis of the state of the prescribed pattern detected from the second image, generates a detection image obtained by excluding at least the first region from the first image, sets an instruction light application position on the basis of a feature extracted from the detection image, and sets a second projection condition for projecting instruction light to the instruction light application position.
