Fisheye Dewarping

Fisheye cameras are practical when users want to survey a wide area using a single-lens camera.  However, monitoring the camera stream can be disorienting as the camera video will appear warped when initially viewing the camera.

DW Spectrum IPVMS allows users to utilize its Fisheye Dewarping feature to convert the image from a warped, fisheye view into a panoramic view for both RTSP and ONVIF connected cameras, providing the user with a more comfortable way to monitor the camera.

This article will outline how to use the Fisheye Dewarping feature in DW Spectrum.

Supported/Affected Devices

  • DW Blackjack Series
  • DW MEGApix Camera Series (fisheye cameras)

Enabling Fisheye Dewarping

When a fisheye camera is first added to the DW Spectrum Server, the Fisheye Dewarping tool is unavailable in the camera’s miniature toolbar.

To enable Fisheye Dewarping:

  1. Right-click on the camera, then select Camera Settings.

  1. Select the Fisheye tab.

Enable the Fisheye Dewarping toggle.

  1. A highlighted circle will overlay the camera’s fisheye display.

Select if the camera is installed by Ceiling Mount, Wall Mount, or Floor/Table Mount.

Click the Auto Calibration button to prompt DW Spectrum to automatically size the highlighted area to the camera fisheye lens.  Or use the sizing tools to manually shape the highlighted area.

Click the Apply button to save the settings, then click the OK button to close the Camera Settings menu.

  1. The camera’s Fisheye Dewarping tool will now display in the camera’s miniature toolbar.

Click the Fisheye Dewarping tool icon to convert the camera view into a panoramic picture.

  1. The fisheye camera will now display in either a 90-degree, 180-degree, or 360-degree, dewarped view.

Click the Orange Circle to change the Dewarping Mode.

  1. Use the digital joystick and zoom control to maneuver the camera view and digitally zoom the camera.
