How to stitch dual fisheye to equirectangular images Tutorials for Teliportme.com

Converting dual fisheye images to equirectangular format is essential for creating seamless 360-degree panoramas suitable for viewing on platforms like Teliportme.com.

Here’s a simple step-by-step guide on how to achieve this conversion using popular software tools.

Step 1: Choose Your Software

While Teliportme.com hosts and displays 360-degree panoramas, it does not convert fisheye images directly. You will need to use software capable of stitching such images into an equirectangular format. Popular options include:

PTGui: Highly recommended for its powerful features and flexibility.
Hugin: A free and open-source alternative that works well for basic needs.

Step 2: Prepare Your Images

Ensure your dual fisheye images are ready:

Resolution: Check that both images are of the same resolution.
Alignment: Ensure the images are correctly aligned (top-bottom or side-by-side) as per your camera's output.

Step 3: Import Images into the Software

PTGui: Go to File > New Project, and drag your images into the project window.
Hugin: Open Hugin, click on Load Images, and select your dual fisheye images.

Step 4: Set Control Points

Control points are critical for stitching. They help the software understand how to merge the two fisheye images.

PTGui: Automatically adds control points. You can manually adjust them by selecting Control Points tab and editing as needed.
Hugin: Also suggests control points automatically, but you can add or modify control points manually in the Control Points table.

Step 5: Choose Projection

Select the equirectangular projection to convert the fisheye images into a 360-degree panoramic view.

In PTGui: Select Equirectangular under the Projection settings.
In Hugin: Go to the Panorama Editor, and from the Projection menu, select Equirectangular.

Step 6: Stitch the Panorama

Once everything is aligned, stitch the images together.

PTGui: Click on Align Images, and after the alignment is complete, click on Create Panorama.
Hugin: Click on Align, and once done, click on Create panorama.

Step 7: Export and Upload

Save the stitched image in a compatible format (JPG or PNG) and at an appropriate resolution.

Upload the final equirectangular image to Teliportme.com by logging into your account, going to the upload section, and selecting the image file.
