Summary:

A Panoramic Camera displays a panoramic image by stitching together 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.  This article describes how to focus the lenses and align images for panoramic cameras.

Pre-setup Recommendations

The Panoramic Cameras need to have the lenses focused manually.  You must open the camera and rotate the lenses while viewing on a hand-held device or a PC.

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 version:
   

   Model name	Current firmware
   PNM-9022V	PNM-9022V_2.01.02_20230404_R149
   PNM-9031RV	PNM-9031RV_2.22.01_20231101_R542
   PNM-C9022RV	PNM-C9022RV_2.22.02_20231219_R378

   
   
   
3. Use a high-resolution display and a PC with 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. Recommendation for Monitors:
   
   • Use two screens (monitors) if possible.  One for image verification and one for alignment.
   • It may be difficult to verify alignment as the video is reduced to fit the size of the browser window being used for configuration.
   • It would also be difficult to adjust and verify at the same time on one monitor
     
     
     
5. Center line alignment recommendation:
   
   • It is recommended to set the panoramic camera according to the horizontal center line as shown in the figure below.

Image Alignment Method by model:

PNM-9022V:

• Adjust to align CH2 & CH3 (2-3) first using Image alignment as seen below.
• Adjust to align CH1 & CH2 (1-2), CH3 & CH4 (3-4)
• Enable Alpha Blending to smooth the edges if necessary

PNM-9031RV

• Set target distance first based on the images of CH2 & CH3
• Adjust to align CH2 & CH3 first
• Adjust CH1 to be aligned with CH2 and adjust CH4 to be aligned with CH3

PNM-C9022RV

• Set target distance first based on the images of CH2 & CH3
• Adjust to align CH2 & CH3 first
• Adjust CH1 to be aligned with CH2 and adjust CH4 to be aligned with CH3
• Enable Alpha Blending to smooth the edges if necessary.  You can set the strength of Alpha blending between 0 (off) to 30 (Maximum)
