Description
Technical field
The invention belongs to man-machine interactive electronic display technology field, be specifically related to a kind of cam device and with the touch-screen of this cam device.
Background technology
Touch screen technology and respective digital interactive device have greatly improved interpersonal interactivity, have enriched people's life, in fields such as video conference, teaching, are widely used, platform and medium that in the life that more and more becomes a reality, people exchange.Along with the progress of technology, optical sensing location technology becomes the main flow of large-scale or larger touch screen technology gradually.Adopt at present the touch-screen framework of optical sensing location technology to be generally following two kinds of technical schemes:
1, upper position in touch-screen arranges row's infrared lamp, infrared lamp is light source as a setting, some groups of cameras and camera governor motion are arranged between screen and infrared lamp, on other three limits of touch-screen that camera is not installed, extinction sheet is installed, when having object Touch Screen, the light that infrared lamp sends is blocked by object and the camera of reflection quilt screen top captures, and calculate accordingly the position of object, when having external interference light source, external interference light source is by the institute's scattering of extinction sheet and diffuse reflection, can not be captured by camera, avoided misoperation.
2, camera, infrared lamp, filter and retroreflecting bar are encapsulated in the framework of screen, frame assembled is on screen, camera and infrared lamp layering are encapsulated in several corners of screen top, framework is interior with respect to one side that camera is installed, other of framework three limits are provided with retroreflecting bar, infrared lamp provides background light source, when having object Touch Screen, the light that infrared lamp sends blocks not camera-shot through retroreflecting bar reflection quilt object and arrives, and obtains accordingly the position of object.
For the first technical scheme, because higher to camera adjusting position precision, its governor motion is more complicated, and physical dimension is larger, and Installation and Debugging are more complicated, and extinction sheet is also had to higher requirement, and overall plan cost is higher.For the second technical scheme, the technological requirement of retroreflecting bar is higher, in addition camera from retroreflecting bar the region away from, the signal of reflection can be a little less than, algorithm process more complicated, it is poor that this region touches effect, precision is lower.
Summary of the invention
The technical problem that the present invention solves is to overcome the deficiencies in the prior art, provide a kind of cam device and with the touch-screen of this cam device, described cam device is simple in structure, bulk is little, makes camera be easy to safeguard and debugging, and the touch-screen based on this cam device is when guaranteeing positioning precision and touching effect, simplify the structure of camera and governor motion thereof, the size of having dwindled complete machine, cost is low, is easy to safeguard, debugs and realizes.
For solving the problems of the technologies described above, first goal of the invention of the present invention is to realize a kind of cam device, and its technical scheme adopting is as follows:
, comprising fixture, camera, the drive plate being electrically connected to camera, described fixture is provided with hollow cavity, and camera and drive plate are arranged in the set hollow cavity of fixture.
In such scheme, described fixture comprises mutual fastening and forms drain pan and the upper cover of hollow cavity, and the inner side of drain pan and the inner side of upper cover are respectively arranged with for camera and the spacing and fixing position-limit mechanism of drive plate.When drain pan and upper cover are assembled together, position-limit mechanism cooperatively interacts camera and drive plate clamping in cavity, and camera and drive plate are played to spacing and fixation.
