Description
Usage
ROS client
Installation as performed in August 2020
Mount cameras on joints and joints on clamps
Make sure that the camera is not upside-down.
Prepare 16 safety ropes
- Cut to 1 m length
- Use a lighter at both ends
- prepare 8-knots as for rock climbing
Mount cameras on truss and wire them with the two switches
Mount the 16 cameras in the corners and at each 1/4 of the edges. Use the safety ropes, and wire them to the two switches as below.
Orient cameras and adjust focus
Once the setup is up-and-running, adjust the focus of each camera using a marker at 2/3 of the working distance. Skype and screen sharing may be helpful.
* In the corners: the bottom of FoV is parallel to the long edges, and the bottom right corner is vertical.
* At 1/4 of a short: the top of the FOV is horizontal, and the camera points toward the center.
* At 1/2 of a short edge: the bottom of the FOV is vertical, and the camera aims downward.
* At 1/4 of a long edge: the top of the FOV is horizontal, and the camera points toward the center.
* At 1/2 of a long edge: the bottom of the FOV is vertical, and the camera aims downward.
