c# - Space represented by a single Kinect pixel at a given depth -

-

Actually I want to take a straight line between device points and to determine if anything stops it , But in my example, want to make the "laser line" configurable in relation to the distance above the field of view.

Now it is only so easy to get in-depth data at a given pixel point.

Various Depths INMM = DepthImagePixel.Depth;

And it is also easy to say that I want to focus on the 100th line of pixels from the top by doing something like this. (Int i = 0; i & lt; this._DepthPixels.Length; ++ i) //_DepthPixels.Length is clearly 307,200 for 640x480 (if (i & Gt; = 64000 and & amp; i & lt; = 64640) // second vertical pixel line {// Draw line or whatever}}

with something like this Ends.

Enter image details here

but For example, I want to block the line at 50 centimeters from the top of the viewing area at a depth of 3 meters. Now clearly I I understand that the depth increases so much because the area is represented but I am not getting any references or how I work to calculate this relationship.

So, given a given How to calculate the guided space Kinect sensor usage depth

Edit:

So if I understand correctly, / P> 

  double D = 2; // 2 meters Rye double y = 100; Top double wars = 480 to 100px; // 480 pixels vertical resolution double vfov = 43; Kinect Double X = (2 * Monastery Sin (Math.PI * vfov / 360) * D * Y) / VS / 43 ° Vertical Area; // x = 0.30541768893691434/x = 100 pixels below the depth of 2 meters to see 30.5 centimeters from the top area  

  2 sin (PI VFOV / 360) DYX = -------------------------- VRES  
  D : Distance - Orthogonal 
 
 
  
  Y : Distance of the line from the top of the image in pixels 
 
  VRES : vertical resolution of the image in pixels 
 
  VFOO : Digg Vertical field of view to re camera

I am working on the terminal on a shell script after this tutorial SQLAlchemy tutorial. I need to type gt; & Gt; & Gt; Sqlalchemy import column, integer, string & gt; & Gt; & Gt; Class user (base): __tablename__ = 'users' id = column (integer, primary_key = true) name = column (string) absolute name = column (string) password = column (string) def __repr __ (self): return "& lt ; User (name = '% s', absolute name = '% s', password = '% s') & gt; "% (Self.name, self.fullname, self.password) After the problem I have typed the password = column (string) I hit twice and changed .... >> I then took everything back but then an error was thrown because the class already exists ... I am not completely sure how to fix it. How do I open that slip in the shell script and edit it (Add DF to DRR) The error thrown below: / user / giripeters / TFSQLLX / Lib / python2.7 / site-packages / sqlalchemy / ext / decla...

lua - HowTo create a fuel bar -

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
