MARKER DRAWING DEVICE, SYSTEM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/044151
Kind Code:
A1
Abstract:
In the present invention, an image of a subject captured by a camera and sensor output indicating the spatial position of the subject as detected by a ranging sensor are acquired. The image and the spatial position of the subject are recorded in time series. It is determined whether or the spatial position of a tracking point on the subject at a second time overlaps a space including the trajectory history of the tracking point within a drawing determination time period that is based on a first time preceding the second time. If the determination is affirmative, displayed on a display is a virtual reality object comprising a marker drawn on spatial positions which have been passed through by the trajectory history and/or the spatial positions of the tracking point from the second time to a time at which a drawing stop condition is satisfied after the second time.
