The embodiment of the invention provides a projection system and method and a storage medium, relates to the technical field of projection, and is used for solving the problem that whether a projection image is shielded or not is difficult to determine at present. The projection system comprises projection equipment, an image acquisition device and a multimedia controller, the projection equipment is used for projecting an image to be projected onto a projection screen; the image acquisition device is configured to acquire a first frame image on the projection screen at a first moment, acquire a second frame image on the projection screen at a second moment, and send the first frame image and the second frame image to the multimedia controller; the second moment is after the first moment; the multimedia controller is configured to obtain a first frame image and a second frame image; and comparing the first frame image with the second frame image, and determining whether the projection image on the projection screen is shielded or not. In this way, whether the projection image is shielded or not can be determined by collecting the two frames of images of the projection equipment and comparing the two frames of images.
Description
technical field [0001] The present application relates to the field of projection technology, and in particular to a projection system, method and storage medium. Background technique [0002] In the related art, a projection device can project an image onto a projection screen through a light source to provide users with image or video viewing services. Due to the large output light power of the projection device, when the projected light of the projected device irradiates the human eye, it will affect the user's sight, and the projected light irradiates the human eye for a long time, and it will also cause damage to the human eye. [0003] In order to avoid damage to human eyes caused by the light projected by the projection device, it is necessary to determine in time whether the projected image is blocked, so that the projected device can take relevant measures to reduce the damage to the human eye caused by the projected light when the projected image is blocked.
