Abstract

The invention discloses a projection method and projection system, and the method comprises the steps: S1, carrying out the projection of a target projection image, and forming a projection image; S2,acquiring image information of the current projection picture; S3, performing calibration by using the target projection image and the image information of the current projection image acquired in the step S2 to form an adjustment instruction; and S4, adjusting projection parameters according to the adjustment instruction, wherein the projection parameters comprise a projection proportion. Automatic adjustment of the proportion of the projection picture is achieved, manual operation of a user is not needed, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a projection method and a projection system. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a projection screen, and has been widely used in homes, offices, schools, and entertainment venues. However, when the projector is in use, the ratio of the projected screen may not match the screen size. At present, the calibration method adopted for this situation is to manually adjust the size of the projection screen, and the adjustment operation is complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a projection method and a projection system capable of adjusting the projection ratio. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a projection method, including: [0005] Step S1...
