Embodiment 1

[0034] Such as figure 1 Shown is a schematic diagram of the laser teaching interactive system. The signal output device of described imaging device 5 is connected with the signal input device of computer 6, and the signal output device of computer 6 is connected with the signal input device of laser projector 1, and described laser projector 1 passes the output image of computer 6 through lens 2 Projected onto the projection screen 3 , the camera 5 receives the light signal generated by the laser pointer 4 in the projection screen and transmits the light signal to the computer 6 . The computer 6 maps the position coordinates on the projection screen and the computer screen coordinates through software calculations, thereby controlling the computer cursor to move to the corresponding position in the projection screen specified by the laser pointer 4 laser projection spot, and the computer 6 controls the position of the laser projector 1. Set up and control the projected screen...

Embodiment 2

[0036] On the basis of Embodiment 1, this embodiment further sets an imaging device. Due to the use of the laser projector, the light intensity of the laser projector is strong, the projection site does not need to be shaded, and the camera device can clearly capture the real scene of the projection site in a bright environment. Under the control of the computer, the camera device can capture the laser projection spot of the laser emitter and transmit the image of the real scene where the laser projection spot is located to the computer.

Embodiment 3

[0038] On the basis of Embodiment 1, this embodiment further provides a laser projector lens. The laser projector includes a lens, the lens is a short-focus lens, and the focal length of the short-focus lens is less than 6mm.

Abstract

The invention relates to a laser teaching interaction system which comprises a laser projector, a projecting screen, a laser emitter, a camera device and a computer, a signal output device of the camera device is connected with a signal input device of the computer, a signal output device of the computer is connected with a signal input device of the laser projector, the laser projector projects an output image of the computer to the projecting screen, the camera device receives the projecting image on the projecting screen and transmits the projecting image to the computer, the computer maps the position coordinates on the projecting screen and the computer screen coordinates and can control a computer cursor to move to the corresponding position of a projecting light spot image of the laser emitter on the projecting image. The computer can set and control the projecting image. The laser teaching interaction system is suitable for teaching in classrooms, industrial buildings, laboratories, stages and other scenes.

Description

technical field [0001] The invention relates to a teaching system, in particular to a laser teaching interactive system. Background technique [0002] The classic combination of projector and computer has extensive and profound applications in various modern fields. The coordination between traditional projectors and computers is somewhat simplified, just passing from one direction to another. In recent years, electronic whiteboards are in the ascendant and have begun to be used in teaching systems, but there are problems that the light of the projectors stimulates the human eyes and the projectors often need to replace the bulbs. At the same time, ordinary projectors require a shading environment, which affects the lighting of the place of use. In the shading environment, it is difficult for users to clearly watch both the projection and the real scene. Contents of the invention [0003] In order to solve the technical problem that the existing teaching system only has ...
