Embodiment Construction

[0041] Please refer to " figure 1 ” shows an interactive projection system 100 disclosed in the first embodiment of the present invention, which is used to execute at least one trigger operation after a trigger event. The interactive projection system 100 includes a projection device 110 , a data processing device 120 and an image capture device 130 .

[0042] The projection device 110 is used for projecting an image frame S onto a projection plane P. As shown in FIG.

[0043] The data processing device 120 is used to generate an image frame S to be sent to the projection device 110 , and the data processing device 120 can generate a command mark M, and insert the command mark M into the image frame S.

[0044] An image capturing device 130 is used to capture the image frame S projected onto the projection plane P and send it to the data processing device 120 .

[0045] Wherein, after the trigger event occurs, the data processing device 120 recognizes the command mark M in t...

Abstract

The invention discloses an interactive projection system used for executing an interaction method. The interactive projection system comprises a projection device, a data processing device and an image capturing device. The projection device is used for projecting an image picture to a projection plane. The data processing device is used for generating the image picture and transmitting to the projection device, and a command mark is generated by the data processing device and is inserted into the image picture. The image capturing device is used for capturing the image picture projected on the projection plane and transmitting to the data processing device, wherein after the data processing device triggers an event to happen, the command mark is identified in the image picture captured by the image capturing device, and the corresponding trigger work is executed according to the command mark.

Description

technical field [0001] The present invention relates to the interactive operation of projection screen, in particular to an interactive projection system and an interactive method of the projection system. Background technique [0002] When using computer devices and projection devices for presentations, users often face the problem that there is no interactive relationship between the light pen and the projection screen, so it is impossible to generate operation commands for the computer device through the movement of the light pen on the projection screen. [0003] In order to solve the problem, the known technology proposes different ways to enable the computer device to obtain the coordinates of the light pen corresponding to the projected image. One of the methods uses an additional sensor to sense the position of the light pen or the movement state of the light pen to generate a coordinate value corresponding to the coordinate of the image frame. However, the computer...
