Surface Matching never get any results with any data, why? - c++

It seems that you use the release mode to run the program.
I have meet this problem before. When I change to debug mode. Everything works well.

Saving detected facial landmarks into a file

I'm trying to import facial landmark points from webcam or video
using dlib into a file . I can display all detected landmarks on the terminal
but it is only saving the first and second landmark ponits (x,y) into the
output file , and not saving all the detected landmarks into
the output file
#include <dlib/opencv.h>
#include <opencv2/highgui/highgui.hpp>
#include <dlib/image_processing/frontal_face_detector.h>
#include <dlib/image_processing/render_face_detections.h>
#include <dlib/image_processing.h>

while(!win.is_closed())

outputfile<< shape.part(0).x() << " " << shape.part(0).y() << endl;
outputfile<< shape.part(1).x() << " " << shape.part(1).y() << endl;
}
win.clear_overlay();
win.set_image(cimg);
win.add_overlay(render_face_detections(shapes));
}
}
catch(serialization_error& e)

}
catch(exception& e)

}
}
Am I wrong or you want to save all landmarks when you have only:
ofstream outputfile;
outputfile.open("data1.txt");
outputfile<< shape.part(0).x() << " " << shape.part(0).y() << endl;
outputfile<< shape.part(1).x() << " " << shape.part(1).y() << endl;
And even not closing the file correctly. Try with for statement.

Working with GPS Output using C++

Hi I'm working with GPS output. To be more accurate I'm working using the $GPRMC output. Now the output that I get is in the following form:
$GPRMC,225446,A,4916.45 N,12311.12 W,000.5,054.7,191194,020.3 E,*68"
This output constitutes of time, lats, longs, speed in knots, info about course, date, magnetic variation and mandatory checksum.
The image that I have attached shows the current result I'm getting as I'm taking out the sub strings from the string.
Now I'm getting the time in the hhmmss format. I want it in hh:mm:ss format.
Plus I'm getting the longitude as 4916.45 N. I want to get it as 49 degrees 16' 45".
And the latitude as 123 degrees 11' 12". I'm a beginner so I really don't know how to convert the format. I have also attached my code below.
#include<iostream>
#include<string>
#include<sstream>
#include<stdio.h>
#include<conio.h>
using namespace std;
int main()
{
std::string input = "$GPRMC,225446,A,4916.45 N,12311.12 W,000.5,054.7,191194,020.3 E,*68";
std::istringstream ss(input);
std::string token;
string a[10];
int n = 0;
while (std::getline(ss, token, ','))
{
//std::cout << token << '\n';
a[n] = token;
n++;
}
cout << a[0] << endl << endl;
cout << "Time=" << a[1] << endl << endl;
cout << "Navigation receiver status:" << a[2] << endl << endl;
cout << "Latitude=" << a[3] << endl << endl;
cout << "Longitude=" << a[4] << endl << endl;
cout << "Speed over ground knots:" << a[5] << endl << endl;
cout << "Course made good,True:" << a[6] << endl << endl;
cout << "Date of Fix:" << a[7] << endl << endl;
cout << "Magnetic variation:" << a[8] << endl << endl;
cout << "Mandatory Checksum:" << a[9] << endl << endl;
_getch();
return 0;
}
First thing is that your NMEA sentence is wrong, there should be commas ',' before N and W, so you will actually have to parse "12311.12" and not "12311.12 W". You can check it on this site: http://aprs.gids.nl/nmea/#rmc, you should also always check checksum of sentence - for online checks use: http://www.hhhh.org/wiml/proj/nmeaxor.html.
To parse longitude and latitude I suggest regexps, I am notsaying this is regexp is correct - it only parses data you have provided:
#include <iostream>
#include <string>
#include <regex>
#include <iostream>
std::tuple<int,int,int> parseLonLat(const std::string& s) {
std::regex pattern("(\\d{2,3})(\\d+{2})\\.(\\d+{2})" );
// Matching single string
std::smatch sm;
if (std::regex_match(s, sm, pattern)) {
return std::make_tuple(std::stoi(sm[1]), std::stoi(sm[2]), std::stoi(sm[3]));
}
return std::make_tuple(-1,-1,-1);
}
int main (int argc, char** argv) {
auto loc1 = parseLonLat("4916.45");
std::cout << std::get<0>(loc1) << ", " << std::get<1>(loc1) << ", " << std::get<2>(loc1) << "\n";
// output: 49, 16, 45
auto loc2 = parseLonLat("12311.12");
std::cout << std::get<0>(loc2) << ", " << std::get<1>(loc2) << ", " << std::get<2>(loc2) << "\n";
// output: 123, 11, 12
}
http://coliru.stacked-crooked.com/a/ce6bdb1e551df8b5
You'll have to parse that yourself; there's no GPS parsing in standard C++.
You may want to write your own Angle class in order to have 49 degrees 16' 45" as possible output. You'll want to overload operator<< for that.

Get a mesh_3 'off' from Projection_traits_xy_3 constrained delaunay

I've computed a 2D constrained delaunay triangulation from 2.5D data using the projection_traits_xy_3 [1]. Now I would like to get a mesh that I can visualize.
I've managed to do that with 3d delaunay following the manual[2], how could I achieve it with a 2.5D CDT ?
[...]
typedef CGAL::Projection_traits_xy_3<K> Gt;
typedef CGAL::Constrained_Delaunay_triangulation_2<Gt, Tds> CDT;
[...]
CDT cdt;
cdt.insert(points.begin(),points.end());
[...]
¿?
[...]
std::ofstream out(outdir + "out.off");
Polyhedron output_mesh;
CGAL::output_surface_facets_to_polyhedron(¿?, output_mesh);
out << output_mesh;

http://doc.cgal.org/latest/Surface_reconstruction_points_3/
Here comes pseudocode forwriting it into an off file
cout << "OFF\n" << cdt.number_of_vertices()
<< " " << cdt.number_of_faces() << " 0" << std::endl;
std::map<vertex_handle,int> indices;
int counter = 0;
for all finite vertices v {
cout << v->point() <<std::endl;
indices.insert(v, counter++);
}
for all finite faces f {
cout << "3 " << indices[f->vertex(0)]
<< " " << indices[f->vertex(1)]
<< " " << indices[f->vertex(2)] << std::endl;
}
From #Andreas suggestion:
Here comes the code for writing it into an off file
std::ofstream outstream("output.off");
outstream << "OFF\n" << cdt.number_of_vertices()
<< " " << cdt.number_of_faces() << " 0" << std::endl;
std::map<CDT::Vertex_handle,int> indices;
int counter = 0;

{
outstream << it->point() << std::endl;
indices.insert(std::pair<CDT::Vertex_handle,int>(it, counter++));
}

Value always return 0 while calculating [closed]

Improve this question
I was doing an assignment for my subject here and in the assignment, every student is required to create a simple C++ program. The problem here is, when I do not assign a default to a variable, a compile error will occur. However, when I assign a default value (in this case, value = 0), the value will always be 0.
My question is, is there any way to solve this problem while not encountering the compile error?
If there was a similar question asked, could you please also, include the link to the solved question as well? Thank you very much!
[Edit #1: To those who wonder why the code is "messy", I only used simple commands and did not use object oriented components, if/else statements etc. The project created was meant to be composed of "simple codes".]
[Edit #2: This is the output display that I snapped:

An uninitialized variables warning can mean either (1) you forgot to initialize something or (2) you thought you initialized it but didn't. Looks to me that in this case it's the second problem. Your variable names are mixed up.
For example,
feeTotalAfterDiscountedCar = (rateDiscountCar/100) * feeTotalOriginalCar;
feeTotalAfterDiscountedTaxi = (rateDiscountTaxi/100) * feeTotalOriginalTaxi;
feeTotalAfterDiscountedTruck = (rateDiscountTruck/100) * feeTotalOriginalTruck;
These are supposed to be the amounts of the discounts, no? So why are you storing them into feeTotalAfterDiscountedSomething rather than feeTotalDiscountedSomething?
Similarly,
feeTotalAfterDiscountedCar = feeTotalOriginalCar - feeTotalAfterDiscountedCar;
feeTotalAfterDiscountedTaxi = feeTotalOriginalTaxi - feeTotalAfterDiscountedTaxi;
feeTotalOriginalTruck = feeTotalOriginalTruck - feeTotalAfterDiscountedTruck;
Why is the third one storing the result into feeTotalOriginalTruck instead of feeTotalAfterDiscountedTruck? (Note also that if you fix the first problem above, the rhs of the subtraction will also need to change).
Also,
feeRepTotalDiscountedFee = feeTotalDiscountedCar + feeTotalAfterDiscountedTaxi + feeTotalAfterDiscountedTruck;
Similar problem. These should, I believe, all be feeTotalDiscountedSomething rather than feeTotalAfterDiscountedSomething.
The compiler rightfully complains that feeTotalDiscountedCar and feeTotalDiscountedTaxi are uninitialized. You need to initialize them somewhere. Maybe you want the user to enter them somewhere like this:
cout << "Discount Fee Total Taxi:";
cin >> feeTotalDiscountedTaxi;
cout << "Discount Fee Total Car:";
cin >> feeTotalDiscountedCar;
why are you setting them to zero just before printing out?
feeTotalAfterDiscountedTruck = 0;
feeTotalDiscountedTruck = 0;
It will show the error because you are trying to use the variable with out initializing it.
