WebCam

The Motion Detection and the Video Surveillance System

- Management of up to 5 Webcam

- Motion Detection on all the Webcams

- Efficient algorithm for calculating the correlation coefficient based on the moviemnto

- Management of events associated with the movement

- Recording Movies

- Shooting Photos

The platform is capable of handling up to 5 webcam ( the number was simply self-limited ) , being able to assign each of them a pleasure to order . And ' possible to use any type of CAM better if the USB , even economic ones to buy a few euros

On each of the 5 Cam you can take pictures or record a video , as well as to activate the motion detection liking . This is able to provide
- The percentage of movement
- The numerical value of the real movement
Graphically, the changes are shown in red pixels different , with effective graphic effect , see example image above

For the determinazine Movement ( M ) has been used an effective algorithm based on the coefficient of correlations between two variables ; fact The movement is calculated based on the difference between these two variables , namely our images (i1 , i2) , in two instants thereafter. The degree of correlation between the two variables is then expressed by the so-called correlation indices (CI ) .
So our movement M is given by the formula

M = f (IC) dove IC = f (D (i1, i2), D (t1, t2)).

SpeedoMeter

The GPS Navstar System

- Average speed and instantaneous speed n Kmh o Mph

- Car Acceleration ;

- Quality and power of the satellite signal in in db;

- Altitude in mt or feet

- Travel direction respect to the ground

- Latitude and Longitude and thier graphics rappresentation;

- Verticale and orizzontal accuracy of the posiotn in meters

- Graphics Rappresentazione the the satellites;

- Number of Satellites visible

- Satellites details, like power signal, positions, ecc.

The Knight Rider Speedmeter is the natural evolution in perfect style Knight Rider, the RTS Voice Module Speedmeter presented in 2008 .

It allows you to play on the monitor KITT dashboard , providing real-time information collected some interesting and useful direttametne from satellites in orbit NAVSTAR GPS System
It 's possible to monitor, in real time, many parameters retrieved by a normal satellite connection , including
- The instantaneous speed and average speed in kph or mph
- The acceleration of the car;
- The quality and strength of the satellite signal in db ;
- The altitude in meters or feet ;
- The direction of travel relative to the ground
- The indication of the Latitude and Longitude and their graphical representation
- The horizontal and vertical accuracy of your position in meters
- The graphical representation of the satellites on the horizon , visible and those in use;
- The number of visible satellites , as well as their details , such as power, position , etc. .

The philosophy behind the project RoadThunderStorm is 'to ... realize a central control unit with which it was possible maximum interattivta between man and car ...

In line with this philosophy, the access to all these data and ' possible not only via a handy graphical interface touch screen , but also through simple voice commands and voice responses resulting clear
And ' possible, for example , with a simple voice command, enlarge to full screen the Speed ??Display, for foreground the value of the instantaneous velocity , graphical representation of the time course of the velocity , or the display of the satellites on the horizon Monitor 1 or Monitor 2 by managing multiMonitor
Not only with the Scrolling display may have under control much more info ..
The ' Event Driven Agent and the new device that then allows you to associate the action that you want the most for a given value of the velocity chosen . In doing so, exceeded the thresholds set by you , you can activate :
- An audible signal
- KITT to pronounce a sentence,
- Launch an application already in your possession

The operation of Knight Rider Speedmeter

At the activation RTS4KITT Knight Rider Speedmeter will automatically connect to the satellites of the NAVSTAR system, the speed reading will activate only when the signal quality will FIX 3D, or after you hang up at least 4 satellits

Good Geometric alignment of two satellites

In fact, the operation of NAVSTAR is based on the system of military satellites operated by the U.S. government , 24 + 3 spares , sending a series of digital sequences in which the distances are calculated . RTS4KITT Knight Rider Speedmeter as each GPS receiver , can visualize , apart from exceptional cases , at most 12 , or the satellites located in the hemisphere of belonging .
The distance between the satellites and the receiver is calculated by measuring the time necessary to receive the signal from the satellite that issued it . To take the two-dimensional G.P.S. must "hook " at least three satellites. After that has been calculated the distance to each satellite in the GPS calculates a space in which positions the three spheres of radius equal to the distances available . One gets two intersections : one is the station point of the GPS and the other is directly opposite that is discarded. This position is two-dimensional and therefore carries with it a minimum of error because up to this point was not taken into account the height above sea level of the receiver .
It is necessary a third point to obtain a three-dimensional measurement . It is obtained by hooking the signal from a fourth satellite . Of course, the growing number of satellites contacted decreases the rate of the error. The ' Knight Rider RTS4KITT Speedmeter will only activate in this case, to avoid providing inaccurate measurements .

Accuracy: Interference caused by the reflection of signals 2

What matters for the accuracy of the GPS position is received with the position of the satellites in the sky. In practice, the accuracy is higher, the more satellites are widely distributed in the sky, on the contrary, the accuracy is reduced when the satellites are gathered in a confined space. The index of the accuracy of the position is indicated by the indicators of Horizontal and Vertical Accuracy, or the Dilution of Position

where HDOP = Horizontal Diluition of Position and where VDOP = Vertical Diluition of Position
