Static panorama-based virtual panorama production and application (3)

Third, virtual panoramic photos seamless production skills

After shooting the series of photos, the rest is how to stitch and stitch. For the seamless stitching of photos, my experience is: first use professional seamless stitching software (pixmaker, 3Dvista, etc., these software is both free trial version, but also a commercial version, can be purchased according to work needs) for stitching, and then With image processing software (such as Adobe Photoshop) for technical processing, the ultimate virtual panoramic image is obtained.

Here I take pixmaker1.0 Simplified Chinese Business Edition as an example to introduce how to seamlessly assemble and splicing the series of photos we take.

Step 1: Start pixmaker, follow the software prompts, click on "1Snap (snap)", the computer prompts where to capture, select "My Computer", click "OK". According to the computer prompts, select the “Hard Disk Directory” where you store the digital photos, then click on the first photo you take, hold down the shift, click on the last photo you shot, and then click “Open”. At this point you select All photos are all displayed on the computer. At this point you can perform simple processing of the image according to your needs.

Step 2: Click "2Stitch" and the pixmaker software will automatically test and stitch the lens. After the stitching is completed, the virtual panorama preview is directly displayed.

Step 3: Click on "3 publish" and the pixmaker software will prompt you to choose the release mode, including scene mode (.jpeg), web mode (.html) and postcard mode (.exe). We choose the second mode, web page mode (.html), and the software will prompt you to select a web page template. Follow the Chinese instructions all the way until you save it. In this way Pixmaker software automatically generates a complete virtual panorama page and a panorama static image memoryimage.jpeg.

Step 4: If you feel that the virtual panorama is unsatisfactory in the second preview, find the image named memoryimage.jpeg in your saved directory and open it with image processing software (such as Adobe Photoshop) , Professional modification and perfection. After processing, save it as memoryimage.jpeg.

Such a perfect web page format virtual panorama is produced successfully, you can click on aa.html (assuming you save the file name is aa.html) to browse.

Fourth, panorama photo network publishing skills

In fact, a complete virtual panorama page has been generated in the previous step. However, in practice, according to needs, it can be arranged in other web pages. At this time you just need to use the web authoring software (recommended Dreamweaver 4.02 Simplified Chinese version) to open aa.Html and switch to the code view, find this piece of code:

(Define the width and height of the browse window)

(Add a title to the browser window)

(position of the title, parameters: 0, 1, 2, 3, 4)

(type of panorama, parameters: 1-2D, 2-3D)

(Set a delay value for a movie)

(Whether the page opens automatically moves smoothly)

(Panorama smooth movement speed)

(title text color)

(title background color)

(title border color)

(panoramic start side turn angle)

(Panorama starts tilting angle)

(Panorama starts the viewing range)

(Panorama is 360 degrees or non-360 degrees)

(Maximum viewing range of panorama)

(joined static panorama image name)

Then paste this piece of code in the appropriate location in the corresponding web page file.

In the above statement, the parentheses inside are the author's comment statements. When you paste, remove underlining and comment statements. Among them, the following five sentences included in the above statement are later added according to actual needs, and these words are not included in the default generated web page source code.

Fifth, the application of virtual panoramic technology

(I) Application in Education

The virtual panorama technology obtains a certain degree of virtual reality experience at a lower production cost. It has unique advantages in the display of three-dimensional space, the display of three-dimensional objects, the introduction of exhibits, and the construction of virtual scenes. An important process in the education process is the presentation of knowledge information, and virtual panorama technology has a unique advantage in presenting knowledge information. It can provide unlimited VR experience in a wide range of subject areas, thereby accelerating and consolidating students’ learning process. Therefore, it has a very wide range of application prospects in the field of education, especially in architectural engineering, archeology, medical education, tour guide training, history education, chemistry and physics education, social sciences, etc. It has great room for development.

(II) Application in Commercial Field

Panoramic photography is a more practical technology. Today, the network bandwidth is still tight, it is a good tool for displaying quasi-3D graphics on the Internet. However, it is not a true 3D graphics technology after all. It is far less interactive than virtual reality based on modeling technology. However, it now has broad prospects for development. It can be used in websites, multimedia CD production, e-commerce, real estate display, virtual tourism, geographic information systems, hotels, hotels and virtual exhibitions.

Scenario Site Display: The immersive experience, used in architectural decoration, hotels, restaurants, KTV, personalized bar, entertainment city, golf course, art gallery, art gallery, museum, exhibition hall and so on.

Tourism Scenery Shows: Usually people's understanding of the attraction through the brochure is only superficial. Every potential travel consumer wants to experience the excursions of the attractions before the trip. The above vision can be realized through computer virtualization technology. It can also be represented in various forms of touchscreens, optical discs, and live demonstrations.

Real estate display: Really show the living environment and indoor structure of the real estate, which is the best way for the business to show the real estate to the users.

GIS Geographic Information System: Faced with everyone is no longer a flat map, but the actual perception of the city: 360 ° panoramic roaming, so that the city's most representative style concave, with powerful GIS geography Information systems, broadband travel in digital cities take you to the world.

Product display: lifelike objects such as automobiles, motorcycles, fashion, antiques, jewelry, watches, art, clothing, toys, equipment, appliances, etc.

Investment promotion: The investment environment is represented by virtual roaming and three-dimensional roaming. The potential resources can be integrated with other forms. At the same time, the browsing mode suitable for the Internet makes the attraction of tourism investment more user-oriented.
