Detailed Description

Driver for the Sick LD-MRS laser scanner.

Warning

For the moment, this driver works only on UNIX platform.

The code below shows how the four laser scan provided by the Sick LD-MRS could be acquired.

#include "visp3/sensor/vpSickLDMRS.h"
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
#if !defined(_WIN32) && (defined(__unix__) || defined(__unix) ||
(defined(__APPLE__) && defined(__MACH__))) // UNIX std::string ip =
"131.254.12.119";
 
  vpSickLDMRS laser;
  laser.setIpAddress(ip);
  laser.setup();
 
  vpLaserScan laserscan[4];
  for ( ; ; ) {
    // Get the measured points in the four layers
    laser.measure(laserscan);
 
    // Prints all the measured points
    for (int layer=0; layer<4; layer++) {
      std::vector<vpScanPoint> pointsInLayer = laserscan[layer].getScanPoints(); vpScanPoint p;
 
      for (unsigned int i=0; i < pointsInLayer.size(); i++) {
        std::cout << pointsInLayer[i] << std::endl;
      }
    }
  }
#endif
