Description
Technical field
The present invention relates to the real-time positioning field of pressure sensing, especially a kind of positioning system and side based on electric silica gel
Method.
Background technique
1, currently, in the application that mobile object pinpoints, the camera or infrared sensor typically used comes
The capture of the mobile object of completion.Such as: the 1. walking of the true people of VR needs to capture the distance and speed that people walks using camera
Degree, inside this process captured, camera capture can not accurate personnel's movement distance, if captured using infrared,
It is highly susceptible to the interference of outside light again.2. camera and infrared equal light capture, it is easy to produce and blocks, when there is a people to exist
Front, subsequent people or object will likely can be blocked, and can not recognize in the region being blocked whether there are also the presence of object.
2, the triggering of the pressure signal of multi-point monitors collective motion speed, orientation and the closeness of more objects: when us
In one piece of region, need to obtain the action orientation and velocity of some object.We just need the object in this movement now
Corresponding direction sensor and velocity sensor, or some cameras of installation are installed above to scan the movement side of this object
To and speed, these data are obtained above from these sensors.When there is many objects to need to flow through this region, come receipt these
When the speed of material flows, orientation and closeness, we just need to install corresponding various sensors on each object, right
For the flowing object changed at any time, operate in this way ten points it is inconvenient, and these objects are checked by installation camera
When the speed of body, orientation and closeness, camera is blocked just not being easy to generate between equal object.
3, reality and virtual Region Matching: present VR technology is very flourishing, we are playing VR virtual world
When be all often to be tied up in a fixed place by a waistband, then moved in a disc area, some disks
Pedestal can move, and the direction walked about just is embodied in virtual world, however this body-sensing is not to suit very much to the experience of people,
When walking on disk, experiencer need tied up by waistband, prevent it from falling, at the same walk it is discontinuous and all do not taking action freely
It cannot completely be embodied above body-sensing with the matching of virtual world.And inside some VR education contents and game content, it is
Need real people that walking, such as a certain distance of really walking about is gone then to go to handle something to any some region
Feelings are then return to some point.In order to reach this point, it is necessary to spread pressure on ground and check equipment.Such as carpet, glue,
Within floor.In order to check pressure just need using pressure sensor (such as: capacitance pressure transducer, resistive pressure
Sensor, inductance pressure transducer etc.), but if intensive in one piece of region spread these existing pressure sensings
Device, will increase on volume first carpet, glue or floor thickness.These sensors are very expensive simultaneously, and this
A little sensors are all single point signals transmission, such as a point needs 22 lines of power supply, signal lines, then needing all
Signal is all acquired and is come out, and the route on the controller of whole collecting signal will be very more, and such production considerably increases
The cost of equipment.It by using the mode of conventional sensors, goes to be laid with ground, then will have both positive and negative electricity in region
Pressure has the hidden danger that circuit fever is under fire if circuit is pressed down or short circuit, and danger coefficient is higher.
