Abstract

The invention relates to a feedback type projector system which comprises an outer shell. A lens is arranged at the front end of the outer shell, an image sensor is arranged below the lens, a controller, an optical imaging module and a light source are arranged in the outer shell, a communication component, a signal light and a manual control button are arranged on the bottom of the outer shell, the communication component is connected with the controller, a signal input interface connected with the controller is formed in the top of the outer shell, the signal input interface is connected with external data equipment, the image sensor is focused on a projection screen, the image sensor collects image signals and transmits the image signals to the controller, the controller extracts data of the external data equipment at the same time, and the controller processes the data and outputs images and synchronous data of the external data equipment in real time. The image information feedback and displaying functions are added on the projector system, so light spot writing tracks can be displayed through image feedback after a laser pen scans the screen. Correction displaying of the writing tracks can be achieved in a selected mode, and the problems that the writing tracks cannot be reserved in an original projector system and are extremely inconvenient to watch are solved.

Description

Reaction type projecting apparatus system
Technical field
The present invention relates to a kind of reaction type projecting apparatus system.
Background technology
Current projecting apparatus system is all open cycle system, only unidirectional output image, and in actual use procedure, utility appliance does not leave scanning vestige as laser pen etc. after screen is write scanning, and beholder cannot see hot spot handwriting trace, uses extremely inconvenient.
Summary of the invention
The present invention be directed to present projecting apparatus system and cannot retain the problem of the handwriting trace that shows utility appliance, a kind of reaction type projecting apparatus system has been proposed, gather the original image of screen, extract trace information and by image feedback to optical projection system, spell in projected image, show in the feedback of screen projection thereby realize image, make utility appliance write the rear track while scan that retains of scanning and also show.
Technical scheme of the present invention is: a kind of reaction type projecting apparatus system, comprise shell, and shell front end has camera lens, and camera lens below has imageing sensor, enclosure to have controller, optical imagery module and light source; Outer casing bottom has communication device, signal lamp and manual button; Communication device is connected with controller; Cover top portion has the signal input interface being connected with controller, signal input interface connects external data equipment, imageing sensor focuses distance to projection screen, imageing sensor gathers picture signal and sends into controller, extract external data device data with Time Controller, controller deal with data, in real time output image and external data device synchronization data.
Described communication device can directly be connected with controller, and communication device can also be selected bluetooth module, with wireless mode and controller connecting communication.
Described external data equipment can be laser pen, can be also other sensor or the sensor-based system that characterizes handwriting trace.
Beneficial effect of the present invention is: reaction type projecting apparatus system of the present invention, on projecting apparatus system, add image information feedback Presentation Function, and after can realizing laser pen scanning screen, show hot spot handwriting trace by image feedback.And can select to realize the correction demonstration to handwriting trace, as irregular figure being treated to regular image demonstration etc.Having solved projecting apparatus system handwriting trace in the past cannot retain, and watches extremely inconvenient problem.
Brief description of the drawings
Fig. 1 is reaction type projecting apparatus system structural representation of the present invention.
Embodiment
Reaction type projecting apparatus system structural representation as shown in Figure 1, system comprises shell 1, and shell 1 front end has camera lens 5, and there is imageing sensor 2 camera lens 5 belows, and there is controller 3 inside, optical imagery module 8 and light source 10; Communication device 4 is arranged at described shell 1 bottom, signal lamp 6 and manual button 7; Communication device 4 can be bluetooth module; Signal input interface 9 is arranged at shell 1 top.
Reaction type projecting apparatus system is with imageing sensor 2, and imageing sensor 2 can be the camera that is positioned at body portion, can be also the imageing sensor that is positioned at its optical system inside.
Communication device 4 can directly be connected with controller 3, can also be bluetooth module, connects with utility appliance and carries out communication with wireless mode, utility appliance has data receiver device, can be laser pen, can be also other sensor or the sensor-based system that characterizes handwriting trace, as gesture track extraction system.
Signal input interface 9 is arranged at shell 1 top, and input interface 9 is connected with controller 3, and external image video information equipment is connected with projector as notebook computer passes through input interface 9.
The present invention, by imageing sensor 2 being focused apart to screen, obtains picture signal and passes to controller 3, and controller 3, by processing image, calculates, identifies and extract the handwriting trace of utility appliance, the location track of writing time spot as laser pen on screen.By feeding back to projected image time delay output by assembled image path information, thereby realize reservation the demonstration of handwriting trace on screen.Having solved in the past open loop projecting apparatus system can not feedback image information, can not retain and show that handwriting trace etc. causes user to watch very inconvenient problem.
Meanwhile, after handwriting trace, can process image path information by controller and carry out track characteristic identification obtaining, thereby realize, trace information be carried out to certain correction, as being regular figure by irregular figure trajectory corrector.
In addition, whether the feedback that the present invention can select image by controller 3 whether, is selected processings image to be spelled into former projected image, ensures that the open loop closed loop selection of system is controlled.Can control utility appliance etc. by communication device 4 and people as controller 3 and communicate, thus the remote control that realizes the functions such as trace information reservation, removing select to control, convenient and practical.
