panoramas

A panoramic image is a type of picture or video that shows the entire surrounding environment, capturing all the sights and scenes in one frame through photography or composite technology. Panoramic images can help people better understand their environment and provide a more immersive experience, which has a wide range of applications in fields such as tourism, real estate, gaming, and movies.

Panoramic images were first introduced in the field of photography, where special cameras were used to capture panoramic images or multiple photos were combined to create a single panoramic image. Nowadays, with the development of smartphones and cameras, more and more devices are capable of taking panoramic images.

In the tourism industry, panoramic images can help visitors better understand the overall view of a location. For example, tourists can view a city’s panoramic image online and choose the places they want to visit or find panoramic images of hotels or accommodation online to make decisions based on these images.

In the real estate industry, panoramic images can help potential buyers better understand the entire property. Through panoramic images, people can view all corners of the property both inside and outside, and browse freely. This can greatly improve a buyer’s understanding of the property and reduce the number of times they need to visit the property in person.

In the gaming and movie industries, panoramic images can provide a more realistic and immersive experience for players or viewers. Through panoramic images, players or viewers can feel like they are actually in the scene of a game or movie.

In summary, panoramic images are a very useful technology that can help people better understand their environment and have a wide range of applications in fields such as tourism, real estate, gaming, and movies.

There are generally four ways to create a panoramic image:

1. Use a one-shot panoramic camera, such as Insta360 or Ricoh Theta.

   Pros:

   • Simple and fast, no need for post-processing stitching.

   Cons:

   • Image quality is generally not as good.

2. Use a regular camera and a panoramic shooting bracket, and post-process the images.

   Pros:

   • Able to capture high-quality, high-resolution images.

   Cons:

   • Takes more time and effort;

   • Requires specialized software for post-processing stitching.

3. Use a drone for aerial photography.

4. Some AI applications offer the ability to generate panoramic images based on prompts.

   Pros:

   • Simple and fast, no need for photography knowledge.

   Cons:

   • Can only generate virtual scenes.

1. Open PTGui and import the photos you want to stitch together.
2. Choose the appropriate stitching mode. PTGui offers various modes, such as spherical, cylindrical, and cubic. Choose the mode that suits your needs to ensure a higher quality panoramic image after stitching.
3. Perform automatic matching. PTGui has an automatic matching feature that can identify feature points in the photos and match them. During automatic matching, you can choose whether or not to intervene manually.
4. Manually intervene, if necessary. If the automatic matching is not satisfactory, you can manually adjust the position of the photos, modify the control points, and perform other operations.
5. Stitch the photos. After all the photos are matched, you can stitch them together. During the stitching process, you can adjust the stitching parameters to achieve better results.
6. Perform post-processing. After stitching, you can perform post-processing, including adjusting the exposure, contrast, color, and fixing any imperfect areas in the panoramic image.
7. Export the panoramic image. Finally, export the panoramic image in the desired format.
