Panoramic Camera Alignment Setup Guide (PNM-C9022RV, PNM-9031RV, PNM-9022V)

Summary 

A panoramic camera displays a panoramic image by stitching four images from four different sensors. Due to this characteristic, when images with different target distances are included in the combined image, the alignment of the image on the borderline between the sensors may look unnatural.

Below article describes how to align images for panoramic cameras

Pre-setup Recommendation

1. Minimum distance

In the case of a panoramic camera, since 2 to 4 images with different scenes are stitched and shown, a minimum distance between the camera and the subject is required.  The minimum distance for stitching is about 5M.

2. Please upgrade the camera’s F/W to the latest

3. Use a high-resolution display and a PC with a high graphic performance

Hanwha Panoramic cameras are high-resolution (4K ~ 15M) cameras, so if a low-resolution display and/or a low graphic PC is used, it may be difficult to adjust the image properly.

4. Setting menu location

Webviewer: Setup > Video & Audio > Image alignment

5. Recommendation for Monitor Screens

Use two screens(monitors) if possible.

The video is reduced to fit the size of the window browser in the Camera’s Webviewer setup window, so it may be difficult to verify alignment.

Also, it would be difficult to adjust and verify at the same time with a single window.

Therefore, utilize one monitor for image verification and the other one for the image alignment setting is recommended

6. Center line alignment recommendation

It is recommended to set the panoramic camera according to the horizontal center line standard as shown in the figure below.
