Fisheye Dewarping

Only supported on Ubuntu 12.04, Ubuntu 14.04, Windows 7, 8, and Windows Server 2010.
These instructions are dependent upon your system supporting OpenGL 3.0 or higher.

UBUNTU 12.04 and 14.04

On an exacqVision Server, change the Operating System to automatically login to “admin” following the instructions in KB 39795.
If on 14.04, run the following single-line command in terminal:
sudo mv /usr/local/exacq/webservice/bin/libz.so.1 /usr/local/exacq/webservice/bin/libz.so.1.disabled
Place the attached webservice_fisheye_fix.sh file in “/home/”
Place the attached webservice_fisheye_fix.desktop file in “/home/admin/.config/autostart/”
In Terminal, run
sudo chmod 766 /home/webservice-fisheye_fix.sh
Reboot
NOTE: If your webservice fails to start after the reboot, rename the file back because it does not exist on your system or the webservice is incompatible with the system version:
In Terminal, type sudo mv /usr/local/exacq/webservice/bin/libz.so.1.disabled /usr/local/exacq/webservice/bin/libz.so.1

To revert:

Delete the 2 files from steps 3 and 4.
Configure the machine to login as “User”, then run this command:

sudo mv /usr/local/exacq/webservice/bin/libz.so.1.disabled /usr/local/exacq/webservice/bin/libz.so.1

Axis-fisheye-camera-dewarping-and-the-exacqVision-Web-Service.pdf

With most panoramic cameras in exacqVision, you can dewarp a panoramic image by enabling Digital PTZ and digitally zooming into the fisheye image. However, Axis M3007 panoramic cameras are dewarped using multistreaming.

To enable the panoramic views, the camera must be in Ceiling orientation. To select this orientation, open the camera’s web configurator, select Setup, select System Options, select Advanced, select Plain Config, select ImageSource from the drop-down list, click Select Group, and select Ceiling from the Camera Tilt Orientation drop-down list. (If you do not see this option, select Image from the first drop-down list and enable the images before you click Select Group.)

In Ceiling orientation, an Axis M3007 camera contains four default views: Overview (fisheye), Panorama, Double Panorama, and Quad View. You can also manually configure up to four individual view areas. For access to the streams, enter the IP address of the camera in a browser to open the camera’s web configurator, select a stream from the Source drop-down menu on the Live View page, and click Go.

The following images depict each of the default views:

To configure individual view areas, open the camera’s web configurator again and select a view area from the Source drop-down list. Move the pan, tilt, and zoom sliders to configure the view area as desired.

The streams can each be added in exacqVision on the Camera Settings page.
