Simulated laser data (Laura and Joep)

Output of the laser simulation with Rviz Structure message from laser: frame_id: /pico/laser angle_min = -2.35738992691rad (approx 134 degrees) angle_max = 2.35738992691rad (approx 134 degrees) angle_increment = 0.00436553684995 time_incremetn Header header # timestamp in the header is the acquisition time of # the first ray in the scan. # # in frame frame_id, angles are measured around # the positive Z axis (counterclockwise, if Z is up) # with zero angle being forward along the x axis float32 angle_min # start angle of the scan [rad] float32 angle_max # end angle of the scan [rad] float32 angle_increment # angular distance between measurements [rad] float32 time_increment # time between measurements [seconds] - if your scanner # is moving, this will be used in interpolating position # of 3d points float32 scan_time # time between scans [seconds] float32 range_min # minimum range value [m] float32 range_max # maximum range value [m] float32[] ranges # range data [m] (Note: values < range_min or > range_max should be discarded) float32[] intensities # intensity data [device-specific units]. If your # device does not provide intensities, please leave # the array empty. Questions: sample frequency system/laser?
