Problems solved by technology
[0003] In the process of implementing the present application, the inventor found that in related technologies, most of the dynamic projection equipment only considered the rotation speed of the projection equipment itself, and did not consider the movement speed of the projected picture on the actual projection bearing surface, and could not control the reality. The moving speed of the projected screen in the middle, resulting in a poor experience for the viewer

The invention relates to the technical field of projection, in particular to a projection method and device, projection equipment and a storage medium, and the method comprises the steps: obtaining the movement distance of a projection picture, and obtaining the elapsed time within the movement distance according to the movement distance and the preset movement speed of the projection picture; obtaining a target angle of the projection module according to the target projection point and the first corresponding relation; obtaining a change angle based on the target angle and the initial angle, and obtaining an angular velocity according to the elapsed time and the change angle; and controlling the projection module to rotate through the holder based on the angular velocity so as to control the moving speed of the projection picture on the projection bearing surface. According to the embodiment of the invention, the rotation angular speed of the projection module is determined according to the preset movement speed of the projection image based on the corresponding relation between the reference point on the projection image and the angle of the projection module, and the projection module is controlled through the holder based on the rotation angular speed, so that the projection module can keep approximately uniform motion, and the watching experience of viewers is improved.
Description
technical field [0001] The present application relates to the field of projection technology, and in particular to a projection method, device, projection equipment and storage medium. Background technique [0002] Projection equipment is a device that uses optical components to project projection images such as images or videos onto the projection surface. It can be connected to terminals such as computers and mobile phones, and project the projection images provided by the terminals onto the screen for playback. Projection equipment is widely used in scenes such as homes, offices, schools, and entertainment venues. [0003] In the process of implementing the present application, the inventor found that in related technologies, most of the dynamic projection equipment only considered the rotation speed of the projection equipment itself, and did not consider the movement speed of the projected picture on the actual projection bearing surface, and could not control the reali...
