Description
Technical field
The present invention relates to the multimedia equipment field, more particularly, relate to a kind of real object video showing system with network function.
Background technology
Visual real object display stand is one of indispensable teaching equipment of multi-media classroom, can be applied in the various information technique teaching, when connecting on projector or televisor, just data, teaching materials, material object, lantern slide etc. clearly can be displayed.
Common video showing platform comprises several parts: camera, light source, table top and PC end are controlled software.The objects such as books file, material object are placed on the table top of show stand, after being positioned at the camera aligning material object of table top top, can be on the projecting plane (for example: display device) upper output picture in kind.When the PC end was used visual real object display stand software, the operator need to carry out for the ad-hoc location of material picture on projected picture the emphasis indication sometimes, and the implementation of prior art is as follows:
The first implementation is, directly given directions on material object by the operator, yet such operation very easily causes and produces afterimage of image on projected picture, makes the position that on projected picture, on material picture, respective operations person gives directions present a slice black region;
The second implementation is, directly given directions the relevant position of material picture on projected picture with laser pen by the operator, yet, there is the phenomenon of giving directions poor effect in such mode, this is because the acting surface of laser pen is little, can't highlight its position on the projecting plane of light, often need the operator to rock back and forth laser pen;
The third implementation is, be connected with Usb between show stand and PC, annotated and commented on by the application software correlation function button that the operator controls video presenter with the PC end, this is also the most practical and advanced up to now a kind of processing mode, but in actual application, this kind mode also more and more can not meet the colourful teaching process of giving lessons.Maximum shortcoming is exactly that the teacher place that can only fix in the classroom operates, and can't carry out face-to-face in-plant interaction with the student.In addition, Usb connects the distance problem that will consider between PC and video presenter, and dirigibility is not high.
As seen, existing visual real object display stand, when need the operator for projected picture on the ad-hoc location of material picture when carrying out the emphasis indication, easily occur between operation inconvenience, the site limitation of giving lessons, PC and the problem such as show stand distance.
Summary of the invention
In view of this, the invention provides a kind of real object video showing system with network function, the convenient operation person annotates and comments on and revises by wireless and wired picture in kind that article showing platform is exported, and simultaneously visual real object display stand correlation function button is carried out wireless or wired Long-distance Control.
