Abstract

The present invention provides a method for controlling a projection device, comprising: receiving a projection instruction, analyzing projection information included in the projection instruction, the projection information including destination location information and target projection location information; and a preset map, controlling the projection device to move to a target position; controlling and adjusting the projection height and / or angle according to the target projection position information, so that the projection position of the projection device is adjusted to the target projection position. The present invention realizes the rapid pick-and-place of the projector and the automatic adjustment mechanism of the projection angle, and can ensure stable and vibration-free projection during the projection process.

Description

technical field [0001] The present invention relates to the technical fields of automatic control, positioning and projection. Specifically, the present invention relates to a control method of a projection device, a control device thereof, and a projection device. Background technique [0002] In modern teaching and work, projectors are often used. The projectors are fixed and installed in different positions according to different usage occasions. When they need to be used in other occasions, the previously installed projectors need to be disassembled and fixed again. It can be used only after it is installed, which makes it inconvenient to install, disassemble and use the projector, or buy a new projector for projection, which increases the cost and increases the workload of installation and fixation. And because the projection process needs to maintain a stable projection without vibration, therefore, the projector needs to be adjusted many times to maintain the stabilit...
