BoundingRect Height

Hello, does anyone know how to get the BoundingRect Height data for a particle in the vision analysis. My team used a vector<particleanalysisreport> but all we could find was boundingRect which did not tell us anything.

Re: BoundingRect Height

Sure thing. When you get the vector back, I'll assume (for the moment) that you can iterate through the vector and get the ParticleAnalysisReport objects back...

Code:

ParticleAnalysisReport& par = (*vPAR)[i];



int h = par.boundingRect.Height;

I am doing this a bit from memory earlier today - but basically there is a "Rect" structure which is what boundingRect is within the Report class. It has Top/Left/Width/Height.

That's the ticket.

Re: BoundingRect Height

The definition of Rect is in WPILib\nivision.h

Code:

typedef struct Rect_struct {

    int top;    //Location of the top edge of the rectangle.

    int left;   //Location of the left edge of the rectangle.

    int height; //Height of the rectangle.

    int width;  //Width of the rectangle.

} Rect;

Re: BoundingRect Height

Thanks for the help. If I know a particle location in the vector like
int particle
vector->at(particle); //particle is the particle number i want
is the correct sysntax to get the boundingrect height

ParticleAnalysisReport& par = (*vector)[particle];
int h= par.boundingRect.height;

Re: BoundingRect Height

Code:

ParticleAnalysisReport *p;

int rectWidth;

int rectHeight;

for (unsigned i = 0; i < particles->size(); i++)

{

    p = &(particles->at(i));

    rectWidth = p->boundingRect.width;

    rectHeight = p->boundingRect.height;

}
