Camera_interface

This application is an interface to the Sony EVI-D31 pan/tilt camera.  This camera is possible to control with a set of VISCA commands, see http://www.sfc.wide.ad.jp/sony/EVID30/doc/index.html.
When staring the camera_interface application it creates an actor for the camera and gives it a new set of tcl-commands, see below. The application also connects to a serial port on the computer to communicate with the EVI-D31.
 

The camera_interface application takes the following paramenters      
-serial the serial port to which the EVI-D31 is connected. Default value is /dev/ttyd2.
-camera_obj the .vr-file that describes the camera actor. Default is sony_camera.vr. 
-actor  if this parameter is given the application look for the specified actor and if it finds it it looks for a subobject called 'tool_belt'. If it is found the camera object will be attached to the 'tool_belt'.
The default camera object 'sony_camera.vr' can open up a window with some of the functionality that the remote control has. This window is accessed by clicking on the object in DIVE.

Tcl-commands

All of these tcl-commands interface to the same functions that are accessible through the remotecontrol that comes with the EVI-D31. For a full description of each functionality see the Operating Intructions book that comes with the camera.
