Dear all,<br />
<br />
I have te following problem: I want to display a single point laser measurement in RVIZ using LaserScan message. Terefor I filled most of the laser message parameters manualle. The range was set by the laser<br />
(Leuze ODSL-30)<br />
<br />
The message generated looks fine, but when i subscrive to the /scan RVIZ refused to display it.<br />
<br />
When I use rostopic echo, the message looks like this<br />
<br />
<br />

<br />
Maybe the params angle_min: 0.0<br />
angle_max: 0.00999999977648<br />
angle_increment: 0.00999999977648<br />
time_increment: 0.10000000149<br />
scan_time: 0.10000000149<br />
<br />
are wrong (because I have only one scan in contrast to the hokuyo which has multi scans per reading).<br />
<br />
I though also to use the RANGE sensor message but there seems no way to display it in RVIZ as well.<br />
<br />
Any Ideas?<br />
<br />
Cheers,<br />
<br />
