Problems solved by technology

[0003] The existing technology does not realize the rotation of the projection screen, it is a fixed direction projection, when the user faces the projection device to watch, the projected image is upside down, and the experience is not good
Existing projections mainly project images onto walls or curtains, but not onto desktops. To project existing projectors onto the desktop, they need to be picked up by external force and projected on the desktop, or set up with a shelf to project the projector onto the desktop. , and even if it is projected on the desktop, the projected picture will not automatically judge whether there is a user in use, nor will it distinguish the position where the user is standing, so as to automatically adjust the direction of the projected picture

Abstract

The invention discloses a projection device. The projection device comprises an acquisition part used for acquiring a human body image based on an obtained sensing signal; a detecting part used for detecting a projection direction of the projection device; a processing part used for carrying out face recognition for the human body image to obtain a human body direction and rotating a pre-stored to-be-projected image based on the human body direction if the projection direction is a vertical direction; and a projection part used for projecting the rotated to-be-projected image onto an appointed screen. By adoption of the technical scheme, a projection screen can be adjusted based on a use direction of a user automatically, and great convenience is brought to usability for the user.

Description

technical field [0001] The invention belongs to the technical field of projection equipment, and in particular relates to a projection equipment capable of rotating and projecting images. Background technique [0002] At present, known projection devices generally project in a fixed direction, but when the projecting device can change the projection direction, the projection screen needs to adjust the rotation angle of the projection screen according to the angle facing the user, so that the user can use the projection screen regardless of the projection direction. You can see the front projection screen in any direction, not the upside-down projection screen. [0003] The existing technology does not realize the rotation of the projected picture, and it is a kind of fixed-direction projection. When the user faces the projection device to watch, the projected image seen is upside down, and the experience is not good. Existing projections mainly project images onto walls or ...
