Hello,

I am trying to develop a laser sensor to project a line over a object surface and visualize this line projected over a camera sensor, unfortunately I do not found much about this on internet.

I found this question from 2015 asking basically the same, but when I try to reproduce the answer it doesn't work and do not give me back any ERROR LOG.

Does anyone already made something similar?

Thanks for your time.

I found a way to work it.

I am using a gazebo sensor called projection as code present below but when you call the texture you must add it to gazebo root files. As I am using Gazebo 7 I create a texture and move it to folder /usr/share/gazebo-7/media/materials/textures and it works as it should.

I am able to project a texture over objects surfaces and being able to see this texture projected at camera sensor.

    <gazebo reference="projector_sensor_link">
        <!--sensor type="projector" name="projector_tester"-->
        <projector name="projector_test">
            <pose>0 0 0 0 0 0</pose>
            <texture>your_texture.png</texture>
            <fov>${fov}</fov>
            <near_clip>0.1</near_clip>
            <far_clip>10</far_clip>
        </projector>
    </gazebo>

You can define a visual plugin for this.: http://gazebosim.org/tutorials?tut=ro...
