Description
Technical field
The present invention relates to non-contact control display technology field, more particularly to it is a kind of based on the non-of laser radar range device
Contact control display system.
Background technology
It is currently based in the touch technology of laser, whole system is by Laser emission box, special camera, display device, aobvious
Show that region forms；Static Laser emission box, when whole system works, Laser emission box launches fan laser by display panel,
When being pointed to barrier on display panel, on barrier, special camera recognizes it aobvious by image for laser display
Show regional location, further feed back to control terminal, various starts are further realized in viewing area by display device.
This technological deficiency is mainly reflected in：1st, this technology needs the camera of special sensing laser to be aided in, Jin Er
There can not be any other non-demonstration barrier obstruction in viewing area, need to be noticed that whether to block shooting constantly during use
Head, it is highly inconvenient, and special camera cost is higher；2nd, static Laser emission box entirety size determines that it is launched covering of the fan and swashed
The size of light, so the area of whole viewing area is limited.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art and provide a kind of based on the non-of laser radar range device
Contact control display system, the non-contact control display system is novel in design, simple in construction, low cost, display large area, can be with
Realize single-point or the non-contacting control of multiple spot, can wide variety of scene have teaching demonstration, big screen commanding, conference presentation etc..
To reach above-mentioned purpose, the present invention is achieved through the following technical solutions.
The invention provides a kind of non-contact control display system based on laser radar range device, include laser thunder
Reach, display device, viewing area, the laser radar is the range unit with certain angle and is arranged at the viewing area
Periphery, the laser radar is located at any position outside the viewing area, and high-frequency can scan when laser radar works
The plan-position of certain distance in front of viewing area, laser radar can get current barrier in the distance of viewing area and
Angle information, so as to obtain X of the barrier in viewing area, Y-coordinate positional information, laser radar feeds back to its positional information
Control terminal simultaneously realizes various actions in viewing area by display device.
Wherein, any barrier of its surrounding of the laser radar energy accurate measurement apart from angle information.
Wherein, the viewing area can reach 16m × 16m（It is long × wide）.
Wherein, the viewing area is the plane domain of projection cloth or plane wall.
Beneficial effects of the present invention are：Non-contact control display system of the present invention based on laser radar range device
System, includes laser radar, display device, viewing area, and the laser radar is the range unit with certain angle and set
The periphery of the viewing area is placed in, the laser radar is located at any position outside the viewing area, laser radar work
When high-frequency can scan to the plan-position of certain distance in front of viewing area, laser radar and can get current barrier and exist
The distance and angle information of viewing area, so as to obtain X of the barrier in viewing area, Y-coordinate positional information, laser radar will
Its positional information feeds back to control terminal and various actions is realized in viewing area by display device.The present invention has design new
It is clever, simple in construction, low cost, display large area, it is possible to achieve single-point or the non-contacting control of multiple spot, can wide variety of scene
There is the advantages of teaching demonstration, big screen commanding, conference presentation etc..
Brief description of the drawings
The present invention is further detailed below with accompanying drawing, but the embodiment in accompanying drawing is not formed to this hair
Bright any restrictions.
Fig. 1 is the structural representation of the present invention；
Include in Fig. 1：
1 --- laser radar 2 --- viewing area.
Embodiment
With reference to specific embodiment, the present invention will be described.
A kind of as shown in figure 1, non-contact control display system based on laser radar range device, it is characterised in that：Bag
Laser radar 1, display device, viewing area 2 are included, the laser radar 1 is the range unit with certain angle and setting
In 2 any position of viewing area, high-frequency can be scanned to the flat of viewing area front certain distance when laser radar 1 works
Face position, with single barrier or multiple barriers close to any position of scanning area in the front of viewing area 2, laser radar 1
Can get current Obstacle Position apart from angle information, so as to obtain X of the barrier in viewing area, Y-coordinate position
Its positional information is fed back to control terminal and various actions is realized in viewing area by display device by information, laser radar 1.
Further, the laser radar 1 can any barrier of its surrounding of accurate measurement apart from angle information, can wrap
Include any range unit with certain angle；Laser radar range device is that one kind can obtain certain area around it in real time
Interior any barrier is relative to itself distance and the high-accuracy optical gauge of angle information.
Further, because the ranging measuring range of the laser radar is larger, the viewing area 2 can reach 16m
×16m（It is long × wide）More than.
Preferable as the present embodiment, the viewing area 2 is the plane domain of projection cloth or plane wall.
Need to further it explain, the present invention can be set laser radar 1 positioned at whole 2 any position of viewing area,
