Embodiment Construction

[0017] like figure 1 Shown is the operating environment diagram of the preferred embodiment of the multimedia briefing instruction system of the present invention. The multimedia briefing instruction system 10 runs in a projector 1 , and the projector 1 includes an infrared camera 11 , a projection lens 12 and a light source 13 . The projection lens 12 is used to project images onto the screen 2 .

[0018] The infrared camera 11 includes a normal working mode and an infrared working mode. In normal working mode, the infrared camera 11 is used to instantly capture images of objects between the infrared camera 11 and the screen 2 when there is an image playing on the screen 2 . The captured image range 4 is not the range of the screen 2. Generally speaking, the captured image range 4 is smaller than the range of the screen 2, such as Figure 4 shown. When the infrared camera 11 works in the infrared working mode, it is used to monitor the infrared rays in the projection area...

Abstract

The invention discloses a multimedia brief report indication system which comprises a control module, a computation module, a conversion module, a recording module and a projection module, wherein the control module is used for controlling an infrared camera to shoot an infrared projection region on a screen when an infrared ray projects on the screen; the computation module is used for computing a center point coordinate value of the infrared projection region; the conversion module is used for converting the center point coordinate value of the infrared projection region into a coordinate value corresponding to a projector resolution; the recording module is used for searching a position of a pixel point corresponding to the converted coordinate value on the screen; and the projection module is used for projecting a high-brightness light ray on the position of the pixel point on the screen by using a light source. The invention also provides a multimedia brief report indication method. By using the invention, a multimedia brief reporter can safely and effectively make multimedia brief report.

Description

technical field [0001] The invention relates to a multimedia briefing instruction system and method. Background technique [0002] At present, when users make multimedia presentations, most of them use laser pointers to indicate the content of the presentation. According to the US FDA standards, the safety level of laser pointers is above level 2, and direct eye contact may cause permanent damage to the retina. If during the multimedia presentation process, the multimedia presenter uses the laser beam improperly and shoots the laser beam into the eyes of the audience; or the laser pointer is not stored in a good place and is picked up by children to play with, it is inevitable that various accidents will happen. Contents of the invention [0003] In view of the above content, it is necessary to provide a multimedia briefing instruction system, which can safely and effectively perform multimedia briefing instruction. [0004] It is also necessary to provide a multimedia br...
