Detailed Description

XML parser to load and save intrinsic camera parameters.

Warning

This class is only available if libxml2 is installed and detected by ViSP. Installation instructions are provided here https://visp.inria.fr/3rd_xml2.

To have a complete description of the camera parameters and the corresponding projection model implemented in ViSP, see vpCameraParameters.

Example of an XML file "myXmlFile.xml" containing intrinsic camera parameters:

<?xml version="1.0"?>
<root>
  <camera>
    <name>myCamera</name>
    <image_width>640</image_width>
    <image_height>480</image_height>
    <model>
      <type>perspectiveProjWithoutDistortion</type>
      <px>1129.0</px>
      <py>1130.6</py>
      <u0>317.9</u0>
      <v0>229.1</v0>
    </model>
    <model>
      <type>perspectiveProjWithDistortion</type>
      <px>1089.9</px>
      <py>1090.1</py>
      <u0>326.1</u0>
      <v0>230.5</v0>
      <kud>-0.196</kud>
      <kdu>0.204</kdu>
    </model>
  </camera>
</root>

Example of loading existing camera parameters from an XML file:

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpXmlParserCamera.h>

int main()
{
  vpCameraParameters cam; // Create a camera parameter container

#ifdef VISP_HAVE_XML2
  vpXmlParserCamera p; // Create a XML parser
  vpCameraParameters::vpCameraParametersProjType projModel; // Projection
model
  // Use a perspective projection model without distortion
  projModel = vpCameraParameters::perspectiveProjWithoutDistortion;
  // Parse the xml file "myXmlFile.xml" to find the intrinsic camera
  // parameters of the camera named "myCamera" for the image sizes 640x480,
  // for the projection model projModel. The size of the image is optional
  // if camera parameters are given only for one image size.
  if (p.parse(cam, "myXmlFile.xml", "myCamera", projModel,640,480) != vpXmlParserCamera::SEQUENCE_OK) {
   std::cout << "Cannot found myCamera" << std::endl;
  }

  // cout the parameters
  cam.printParameters();

  // Get the camera parameters for the model without distortion
  double px = cam.get_px();
  double py = cam.get_py();
  double u0 = cam.get_u0();
  double v0 = cam.get_v0();

  // Now we modify the principal point (u0,v0) for example to add noise
  u0 *= 0.9;
  v0 *= 0.8;

  // Set the new camera parameters
  cam.initPersProjWithoutDistortion(px, py, u0, v0);

  // Save the parameters in a new file "myXmlFileWithNoise.xml"
  p.save(cam,"myXmlFileWithNoise.xml",p.getCameraName(),p.getWidth(),p.getHeight());

  // Clean up memory allocated by the xml library
  vpXmlParser::cleanup();
#endif
}

Example of writing an XML file containing intrinsic camera parameters:

#include <visp3/core/vpCameraParameters.h>
#include <visp3/core/vpXmlParserCamera.h>

int main()
{
  // Create a camera parameter container. We want to set these parameters
  // for a 320x240 image, and we want to use the perspective projection
  // modelisation without distortion.
  vpCameraParameters cam;

  // Set the principal point coordinates (u0,v0)
  double u0 = 162.3;
  double v0 = 122.4;
  // Set the pixel ratio (px, py)
  double px = 563.2;
  double py = 564.1;

  // Set the camera parameters for a model without distortion
  cam.initPersProjWithoutDistortion(px, py, u0, v0);

#ifdef VISP_HAVE_XML2
  // Create a XML parser
  vpXmlParserCamera p;
  // Save the camera parameters in an XML file.
  if (p.save(cam, "myNewXmlFile.xml", "myNewCamera", 320, 240) != vpXmlParserCamera::SEQUENCE_OK) {
    std::cout << "Cannot save camera parameters" << std::endl;
  }

  // Clean up memory allocated by the xml library
  vpXmlParser::cleanup();
#endif
}

Member Function Documentation

static void vpXmlParser::cleanup ( )

inlinestaticinherited

As stated in http://xmlsoft.org/html/libxml-parser.html#xmlCleanupParser to clean up memory allocated by the xml2 library itself, the user should call xmlCleanupParser() only when the process has finished using the xml2 library. In case of doubt abstain from calling this function or do it just before calling exit() to avoid leak reports from valgrind ! That's why in ViSP the destructor doesn't call xmlCleanupParser(). Rather we provide the static function vpXmlParser::cleanup() that calls xmlCleanupParser() that could be called just before exit().

		const unsigned int	im_height = 0
	)

Parse an xml file to load camera parameters.

Parameters

cam	: camera parameters to fill.

cam_name	: name of the camera : useful if the xml file has multiple camera parameters. Set as "" if the camera name is not ambiguous.
projModel	: camera projection model needed.
im_width	: image width on which camera calibration was performed. Set as 0 if not ambiguous.
im_height	: image height on which camera calibration was performed. Set as 0 if not ambiguous.

Returns

vpXmlParserCamera::SEQUENCE_OK if success and vpXmlParserCamera::SEQUENCE_ERROR otherwise.

void vpXmlParser::save ( const std::string &  filename, const bool  append = false  )

inherited

Save the content of the class in the file given in parameters. The data of the class are in the child class. This method calls the write_main_class method which has to be implemented for every class depending on the data to save.

Parameters

filename	: the name of the file used to record the data
append	: if true and if the file exists, the data will be added to the data already in the file

		const std::string &	cam_name,
		const unsigned int	im_width = 0,
		const unsigned int	im_height = 0,
		const std::string &	additionalInfo = ""
	)

Save camera parameters in an xml file.

Parameters

cam	: camera parameters to save.
filename	: name of the xml file to fill.
cam_name	: name of the camera : useful if the xml file has multiple camera parameters. Set as "" if the camera name is not ambiguous.
im_width	: width of image on which camera calibration was performed. Set as 0 if not ambiguous.
im_height	: height of the image on which camera calibration was performed. Set as 0 if not ambiguous.
additionalInfo	: Additional information added in the saved xml file. The content of this string should be in xml format.

Returns

error code.

A typical usage would be the following:

#include <visp3/core/vpTime.h>
#include <visp3/core/vpXmlParserCamera.h>

int main()
{
  vpCameraParameters cam;
  std::stringstream ss_additional_info;
  ss_additional_info << "<date>" << vpTime::getDateTime() << "</date>";

  vpXmlParserCamera p;
  if (p.save(cam, "camera.xml", "myCamera", 320, 240, ss_additional_info.str()) != vpXmlParserCamera::SEQUENCE_OK) {
    std::cout << "Cannot save camera parameters" << std::endl;
  }
}

In camera.xml file, you will see:

<camera>
  ...
  <!--Additional information-->
  <additional_information>
    <date>2016/06/10 09:15:56</date>

void vpXmlParser::setMap ( const std::map< std::string, int > &  _map )

inlineinherited

Set the map describing the data to parse. This map stores the name of each node and an associated key used to simplify the parsing of the file.

If the following file want to be parsed:

<config>
  <range>5</range>
  <step>7</step>
  <size_filter>3</size_filter>
</config>

The following map has to be declared:

std::map dataToParse;
dataToParse["config"] = 0;
dataToParse["range"] = 1;
dataToParse["step"] = 2;
dataToParse["size_filter"] = 3;

Or, you can use keyzord instead of number as key but it implies to declare in the child class an enumeration type of the name. For example:

typedef enum{
  config,
  range,
  step,
  size_filter} data_enum;

std::map dataToParse;
dataToParse["config"] = config;
dataToParse["range"] = range;
dataToParse["step"] = step;
dataToParse["size_filter"] = size_filter;

Parameters

_map	: the map describing the data to parse
