Detailed Description

Class used to store a laser calibration. Calibrations can be queried or set for a specific sensor

Example code to query the current laser calibration from a sensor:

 {.cpp}
     //
     // Instantiate a channel connecting to a sensor at the factory default
     // IP address
     crl::multisense::Channel* channel;
     channel = crl::multisense::Channel::Create("10.66.171.21");

     channel->setMtu(7200);

     //
     // Create a lidarCalibration instance to store the queried laser calibration
     crl::multisense::lidar::Calibration lidarCalibration;

     //
     // Query the laser calibration from the current Channel instance
     crl::multisense::Status status = channel->getLidarCalibration(lidarCalibration);

     //
     // Check to see if the laser calibration query succeeded
     if(crl::multisense::Status_Ok != status) {
          throw std::runtime_error("Unable to query laser calibration");
     }

     //
     // Use the laser calibration...

     //
     // Destroy the channel instance
     crl::multisense::Channel::Destroy(channel);

Example code to set a laser calibration:

 {.cpp}
     //
     // Instantiate a channel connecting to a sensor at the factory default
     // IP address
     crl::multisense::Channel* channel;
     channel = crl::multisense::Channel::Create("10.66.171.21");

     channel->setMtu(7200);

     //
     // Create a lidarCalibration instance to store the new laser calibration
     crl::multisense::lidar::Calibration lidarCalibration;

     //
     // Populate the laser calibration. Here we populate the calibration
     // with identity matrices. All MultiSense SL sensors ship  pre-calibrated
     // making this unnecessary.
     lidarCalibration.laserToSpindle = { {1, 0, 0, 0},
                                         {0, 1, 0, 0},
                                         {0, 0, 1, 0},
                                         {0, 0, 0, 1} };

     lidarCalibration.cameraToSpindleFixed = { {1, 0, 0, 0},
                                             {0, 1, 0, 0},
                                             {0, 0, 1, 0},
                                             {0, 0, 0, 1} };

     //
     // Send the new laser calibration to the sensor
     crl::multisense::Status status = channel->setLidarCalibration(lidarCalibration);

     //
     // Check to see if the new laser calibration was successfully received by
     // the sensor
     if(crl::multisense::Status_Ok != status) {
          throw std::runtime_error("Unable to set lidar calibration");
     }

     //
     // Destroy the channel instance
     crl::multisense::Channel::Destroy(channel);
