C :: OpenCV And Detecting A Person With A Webcam
Jul 2, 2013Code:
#include "opencv2/video/tracking.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc_c.h"
#include <stdio.h>
#include <stdlib.h>
[Code] ....
The above code is all I have so far. I got confused when I got to the part where my book on C tells me I need to use the cvCalcOpticalFlowFarneback() function to compare 2 consecutive images from the webcam and create the optical flow, and then measure movement between the frames to detect whether or not a person is moving through the room. How to do this, and the OpenCV wiki wasn't very descriptive on how to set it up for beginners. Honestly, the parameters just confused me and I didn't see a return value listed, or how you would get data from it.

View 1 Replies View RelatedC++ :: OpenCV - Opening And Closing Webcam
Jan 24, 2015I am trying to switch between 2 states, and the event that determines which state i am in is based on the key i've pressed. So in this case i want the webcam to start automatically, and when key is pressed it then turns it off. The way I've done it is like this :
bool webcam_on() {
int c = 0;
VideoCapture cap(0);
if ( !cap.isOpened() ) // if not success, exit program
[Code] .....
The problem with this method is that cin.get() blocks the video stream.. I wanted something that the webcam turned on until i press some key, which would trigger the release.. How can this be done?
C++ :: How To Get A Video Recording As Input From Webcam To One Of Program Functions

Oct 19, 2013I am using SDL 2.0. But I don't know how to handle mouse input. Do you think you can explain of how to do that? Or give me a link that explains that really great?
I know how to handle a mouse button that presses down for a sec.
Code:
if (event.type == SDL_MOUSEBUTTONDOWN){
if (event.button.button == SDL_BUTTON_LEFT){
// Do something . . .
}
}
But not how to handle the mouse input of what the mouse is hovering over and that.
Like in a start menu of a game. I want a button for example to appear blue when I hover over it and when I click on it. It should start the game for example.
C++ :: Visual Arrow Following Motion Of Ball?
Aug 25, 2013I have created plane as floor and sphere as ball. I used physics equations to it and ball falls under gravity. Now i want to attach visual arrow to this ball which moves with it according to velocity direction. If ball bounces then direction of velocity is changed so does arrow.
View 1 Replies View RelatedC/C++ :: Trapezoidal Motion Profile Using Discrete Method?
Mar 9, 2015I'm trying to program an arduino to generate a Trapezoidal Motion Profile to control a DC motor with a quadrature encoder.
Essentially, the user will input the desired Target Position, Max Velocity and Acceleration (decel = -accel) and the code will calculate the target position versus time which will then be compared with the actual position. The result will then be subject to a PID calculation
My initial assumption was that I could use basic Newtonian physics to determine position (i.e. PT = P0 + V0T + 1/2AT2, VT = V0 + AT). However, after reading through documentation for pre-existing motion controllers, I discovered that the prevalent method was to use a discrete time method, which is as follows:
VK = VK-1 + A (A = Acceleration)
PK = PK-1 + VK-1 + A/2
I'm having a hard time understanding quite how this equation would generate the target position versus time. In the case of Velocity, it seems to just add the acceleration to the current velocity. But what about everything in between?

View 2 Replies View RelatedC :: Arduino Programming - Control Motion Of Servo Motor
Jul 16, 2013I am working on a project that requires using an arduino microcontroller to control the motion of a servo motor. The arduino language is pretty much C.
The original code is of the form:
Code:
#include <Servo.h>
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
[Code] .....
But the problem is I don't want the motor's motion to behave linearly (constant increments of the pos variable). My desired motion is a sinusoidal like function. How to approach this?
I am quite new to programming, especially with microcontrollers. My guess is that instead of the pos+=1, I would need something like pos+=sin(argument). I am not sure what that argument should be.
C++ :: Simulation Of Motion Of Magnets On A Rod - Long Double Not Working
Apr 25, 2013I'm currently working on a simulation of the motion of magnets on a rod. As part of it, there are arrays of the properties of the magnets:
long double *accelerations; // These will later be dynamically allocated depending on the number
long double *velocities; // of magnets
long double *positions;
However, when I go to compile this, the compiler gives me these error for the pointers:
error: two or more data types in declaration of 'accelerations'
error: two or more data types in declaration of 'velocities'
error: two or more data types in declaration of 'positions'
Apparently, the compiler isn't recognising long double* as a type and is instead reading is as the two types long and double*.
My compiler is MinGW 4.4.3

Sep 10, 2014I currently have a project that requires me to build a leap motion Virtual Piano. I am using Windows Visual Studio 2013 and i plan to use C++ to code it.
I assume my first step is to create a virtual piano using C++.. Then, link it with leap motion interface.
Can i know which audio library suits my project and how can i go about doing it?
C :: Reading And Accepting Full Name
Feb 6, 2013I am having trouble in reading my full name in just a single variable and some kind of authentication. this is my code by the way.
Code:
#include <stdio.h>
int main(void)
{
char NAME_MINE1[40];
void clrscr();
}
[code]....
if i enter my full name i will be able to go on to the next statement/command but when i put on some name (which is not mine) i will automatically get an error and exit the program.If i type "Qwerty You Tube" EXACTLY and not just the first string before the whitespace i will be able to proceed but when i enter "Qwerty Tube You" or "Qazse Qop Queen" i will get an error and the program will exit.
C++ :: Get Full Time Without Seconds

Here is my code:
struct tm* clock;// create a time structure

stat("test.txt", &attrib);// get the attributes of afile.txt
clock = gmtime(&(attrib.st_mtime));// Get the last modified time and put it into the time structure
C++ :: Not Marking That The Queue Is Full
Apr 11, 2013Why is this code not marking that the queue is full.. I'm just including my Add function that verifies if they want to add another number to the queue. The isFull function works fine, have used it on other programs.
template <class T> //Template currSize function
int Queue<T> :: currSize ()
{
return (rear - front + arraylength) % arraylength; //
[Code].....
The output goes all the way down to 1 spot left, lets the user enter the last element. Then it asks if they want to add another.. At this point, when they hit Y, it lets them add it and it says there are 5 spots left!

C++ :: Create A Pointer To A Full Text Line
Jun 3, 2013It's really simple to say to a pointer to point to a sigle character or a single number.
Code: int *ptr;
int a = 5;
cout << *ptr << endl;
But I want for example a pointer to change a whole text line. My idea is that the user enters which language he speaks.
Code: cout << "English" << endl;
cout << "Swedish" << endl;
But I don't know how to this. I could have done this without pointers with if statments but I want to do it with pointers because it were a exercise to do.
