Embodiment 1

[0041] see figure 1 , is a schematic structural diagram of an interactive projector provided by an embodiment of the present invention. Such as figure 1 As shown, the interactive projector 100 includes a projection module 10 , a first optical element 20 , a filter 30 , an infrared light source 40 , a second optical element 50 and an infrared camera module 60 .

[0042] The projection module 10 is used to emit the projection beam; the first optical element 20 is arranged directly in front of the projection module 10, and the first optical element 20 is used to change the propagation direction of the projection beam so that the projection beam emerges in a ring shape and forms a ring shape. The projection surface 001; the optical filter 30 is arranged between the projection module 10 and the first optical element 20 for transmitting the projection beam; the infrared light source 40 is arranged on the side of the projection module 10 away from the first optical element 20 for O...

Embodiment 2

[0079] see Figure 7 , is a schematic flowchart of an interactive projection method provided by an embodiment of the present invention. The interactive projection method can be applied to the interactive projector 100 in the first embodiment. Such as Figure 7 As shown, the method includes:

[0080] 210. Receive an opening instruction, and according to the opening instruction, control the interactive projector to display a ring projection image, and control the interactive projector to project an infrared beam to the ring projection image.

[0081] The above-mentioned "start command" is an command to start ring projection. After receiving the start command, the interactive projector 100 is controlled to display the ring projection image according to the start command. Wherein, the ring projection image is obtained by the interactive projector 100 projecting the received projection content, and the ring projection image is ring-shaped, and the ring projection image is displa...

Embodiment 3

[0098] see Figure 8 , is a schematic flowchart of an interactive projection method provided by another embodiment of the present invention. The interactive projection method can be applied to the interactive projector 100 in the first embodiment. Such as Figure 7 As shown, the method includes:

[0099] 311. Obtain environmental information.

[0100] The above "environmental information" is an environmental image, which is an image of the real environment obtained by the interactive projector 100 currently taking pictures or shooting videos, and the projection content projected in the environment is determined through the environmental image for user interaction. In this embodiment, the interactive projector 100 may also be provided with a camera to acquire environmental images through the camera. Wherein, the camera may be a color monocular camera or a high-resolution camera or the like. Then, the specific implementation manner of acquiring the environment information i...

Abstract

The embodiment of the present invention relates to the technical field of projection interaction, and discloses an interactive projector and an interactive projection method. The interactive projector includes: a projection module, used to emit a projection beam; a first optical element, used to change the propagation direction of the projection beam, so that the projection beam emerges in a ring shape and forms a ring projection surface; Between the projection module and the first optical element, it is used to transmit the projection beam; the infrared light source is arranged on the side of the projection module away from the first optical element, and is used to emit the infrared beam; the second optical element is arranged on the side of the infrared light source The exit end is used to reflect the infrared beam; the first optical element is also used to receive and reflect the red light beam reflected at the annular projection surface; the filter is also used to reflect the infrared beam reflected by the first optical element; the infrared camera module , set on one side of the reflective surface of the filter, for receiving the infrared light beam reflected by the filter. Through the above methods, the interactive projector of this embodiment can realize circular projection.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of projection interaction, and in particular, relate to an interactive projector and an interactive projection method. Background technique [0002] With the development of semiconductor technology, portable electronic products are increasingly diversified and their functions are more abundant, making users' demand for large-screen projection more and more intense, which in turn drives the development of projection devices. [0003] Interactive projection technology is a hot research item today. The principle of interactive projection technology is: capture and shoot the user's motion through the capture device, and then analyze it to generate the user's motion data, and combine the motion data with the real-time image interaction system to create an interactive effect between the user and the screen. [0004] In the process of realizing the embodiment of the present invention, the inv...
