Projection method, projection equipment and storage medium

Abstract

The embodiment of the invention discloses a projection method, projection equipment and a storage medium, and the method comprises the steps: projecting a display image through a first light source, then projecting a reference image through a second light source at a preset time interval, obtaining a real-time projection position corresponding to the reference image, and judging whether the real-time projection position is different from a target projection position or not: if yes, adjusting the optical axis for projecting the display image so as to enable the real-time projection position to approach the target projection position; in this way, under the condition that the obtained real-time projection position corresponding to the reference image projected by the second light source at the preset time interval is different from the target projection position, the real-time projection position can approach the target projection position by adjusting the optical axis of the projected display image, so the projection effect can be adjusted in the process of not influencing the projection of the display image, and the problem that the quality of the projected image is reduced due to pixel offset is solved.

Description

Technical field [0001] The present application relates to the field of projection techniques, and more particularly to a projection method, a projection apparatus, and a storage medium. Background technique [0002] The projector, also known as the projector, is a device that can project an image or video on the curtain, which can play the corresponding video signal with a computer, VCD, DVD, BD, Game Machine, DV, etc. with a different interface. With the development of projection technology, projectors have been widely used in various conferences and teaching, bringing great convenience to people's daily lives. However, the projector produces a large amount of heat during operation, the projector's optical machine and the lens are heat-modified during operation, resulting in a certain degree of pixel offset from the screen to the screen, resulting in the lack of imaging content. Or severe quality decline, affect the projection effect and the user's viewing experience. Inventive...

Problems solved by technology

However, the projector will generate a lot of heat during operation, and the optical machine and lens of the projector will be heated during the working process to cause thermal deformation, resulting in a certain degree of pixel shift in the picture output to the screen, resulting in the loss of imaging content Or serious quality degradation, affecting the projection effect and the user's viewing experience
