Title:
PAN-TILT-ZOOM DEVICE ROTATION METHOD, PAN-TILT-ZOOM DEVICE, AIRCRAFT, AND METHOD AND SYSTEM FOR CONTROLLING ROTATION OF PAN-TILT-ZOOM DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/023887
Kind Code:
A1
Abstract:
A rotation method (100) executed by a pan-tilt-zoom device, comprising: controlling, according to a received angle command used to indicate a rotation angle of a pan-tilt-zoom device, a driving member of the pan-tilt-zoom device to rotate to the rotation angle of the pan-tilt-zoom device at a preset rotation time (S102); determining whether a new angle command is received within a rotation time (S103); and if a new angle command is not received within the rotation time, estimating, according to rotation angles of the pan-tilt-zoom device indicated by multiple previously received angle commands, a subsequent rotation angle of the pan-tilt-zoom device, and controlling the driving member to rotate from a current angle to the estimated rotation angle of the pan-tilt-zoom device in the rotation time (S104). The invention further provides a corresponding pan-tilt-zoom device (400), an aircraft, a pan-tilt-zoom device rotation control method (500), and a pan-tilt-zoom device rotation control system (600).
