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"
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
}
Examples:
SickLDMRS-Acq.cpp, and SickLDMRS-Process.cpp.
