Embodiment Construction

[0031] The invention provides a projection system, which can solve the problem of misoperation caused by interfering objects on the projection plane compared with the prior art.

[0032] A projection system provided by the present invention includes:

[0033] a projection module, configured to project a picture to a projection plane;

[0034] An infrared emitting device is used for emitting infrared light to the projection plane;

[0035] An infrared camera device is used for taking infrared images at the projection plane;

[0036] A visible light camera device, configured to capture visible light images of user actions at the projection plane;

[0037] The main control module is used for locating the touch position according to the captured infrared image, and locating the outline of the limb where the user makes the touch action according to the captured visible light image. When the determined touch position is within the outline of the limb, Projection control is perfor...

Abstract

The invention discloses a projection system. The projection system includes: a projection module which is used for projecting a frame on a projection plane; an infrared emitting device which is used for emitting infrared light to the projection plane; an infrared camera shooting device which is used for shooting an infrared image on the projection plane; a visible light camera shooting device which is used for shooting a visible light image of a user action on the projection plane; and a main control module which is used for positioning a touch position according to the shot infrared image, positioning a limb profile of a touch action generated by a user according to the shot visible image, and performing projection control according to the touch position when it is determined that the touch position is located in the limb profile. When other articles exist in the projection plane, if the touch action is generated by other articles, in this situation, the positioned touch position is not in the limb profile of the user, and projection control is not performed. Accordingly, the projection system can solve the problem that wrong operations occur while interference articles exist in the projection plane.

Description

technical field [0001] The present invention relates to the technical field of projection, in particular to a projection system. Background technique [0002] Interactive projection is a new technology that has developed rapidly in recent years. The projector projects the picture onto the screen, wall or desktop, and captures the user's touch motion image, and locates the user's touch position in the projection screen according to the motion image. Further, an interactive effect between the user and the projection screen is realized. [0003] In the prior art, the specific implementation method of interactive projection is to use an infrared laser to emit infrared light to the projection plane, use an infrared camera to capture user action images, and locate the touch position according to the infrared image. This implementation has the advantages of low cost and simple image processing, but when there are other objects on the projection plane, the touch of other objects on...
