Virtual panoramic production and application based on static images (III)

III. seamless production skills of virtual panoramic photos

after taking a series of photos, the rest is how to sew and splice. For the seamless splicing of photos, my experience is: first, professional seamless splicing software (pixmaker, 3dvista, etc., which are available in both free trial and commercial versions, and can be purchased according to work needs) is used for splicing, and then image processing software (such as Adobe Photoshop) is used for technical processing, and finally a perfect virtual panoramic picture is obtained

let me take pixmaker1.0 simplified Chinese commercial edition as an example to introduce how to seamlessly synthesize and splice the series of photos we have taken

step 1: start pixmaker, click "① snap" according to the prompts of the software, and the computer will prompt where to capture, select "my computer" and click "OK". According to the computer prompt, select the "hard disk directory" where you store digital photos, then click the first photo you took, press and hold shift, click the last photo you took, and then click "open". At this time, all the photos you selected will be displayed on the computer. At this point, you can simply process the image according to your needs

step 2: click "② stitch", and pixmaker software will automatically test and splice the lens. After splicing, the virtual panoramic preview is displayed directly

step 3: click "③ publish", and pixmaker software will prompt you to select the publishing mode, including scene mode (.Jpeg), page mode (.Html) and Postcard mode (.Exe). We choose the second mode - page mode (.Html). The software will prompt you to select the page template, and follow the Chinese prompts all the way until you finally save it. In this way, pixmaker software automatically generates a complete virtual panoramic page and a panoramic static image eg

step 4: if you feel dissatisfied with the virtual panorama in the preview of step 2, find the image named eg in your saved directory and open it with image processing software (such as Adobe Photoshop) for professional decoration and improvement. After processing, save it as eg

such a perfect page format virtual panorama is created successfully. You can directly click ml (assuming that the file name you save is ml) to browse

IV. tips for publishing panoramic photos

in fact, a perfect virtual panorama page has been generated in the previous step. But in practice, it can be arranged in other pages as needed. At this time, you only need to use the page making software (Dreamweaver 4.02 simplified Chinese version is recommended) to open ml and switch to the code view, Find this Code:

applet name= "template1" code= "ass" archive= "R" width=400 height=150 (define the width and height of the browsing window)

param name=title value= "" (add prompt title to the browsing window)

param name=titlepos value= "0" (Title position, parameters: 0, 1, 2, 3, 4)

param name=viewtype value= "1" (panoramic type, parameters: 1-2D, 2-3D)

param name=autopandelay value= "0" (set the delay value of a movie)

param name=hp value= "1" (panoramic quality: 0 - normal quality, 1 - high quality)

param name=autopan and use graphene material value= "yes" (whether the page is automatically moved smoothly when opened)

param name=autopanspeed value= "10" (panoramic smooth moving speed)

param name=titleforegroupcolor value= "ff0000" But what is the degree of fragmentation (title text color)

param name=titlebackgroundcolor value= "ffffff" (title background color)

param name=titlebordercolor value= "000000" (Title border color)

param name=startyaw value= "0" (full view start lateral rotation angle)

param name=startpitch value= "0" (panoramic start oblique rotation angle)

param name=startfov value= "180" (panoramic starting viewfinder range)

param name=partialstitch value= "yes" (panoramic is 360 degrees or not)

param name=horfov value= "272" (panoramic maximum viewfinder range)

param name=url value= "g" (connected static panoramic image name)

/applet

then paste this code in the corresponding position in the corresponding page file

in the above sentence, unless the government has subsidies, the comments of the author are in brackets. When pasting, remove the underline and comment statements. Among them, the following five sentences included in the above statement were added later according to actual needs. They are not included in the page source code generated by default

param name=autopandelay value= "0"

param name=hp value= "1"

param name=titleforegroundcolor value= "ff0000"

param name=titlebackgroundcolor value= "ffffff"

param name=titlebordercolor value= "000000"

v. application of virtual panoramic technology

(I) application in the field of education

virtual panoramic technology low production cost to obtain a certain degree of virtual reality experience, It has unique advantages in the display of three-dimensional space, the display of three-dimensional objects, the introduction of exhibits, the construction of virtual scenes and so on. A very important process in the process of education is presenting knowledge and information. Virtual panoramic technology has unique advantages in presenting knowledge and information. It can provide unlimited VR experience in a wide range of subject areas, so as to accelerate and consolidate the process of students' learning knowledge. Therefore, it has a very wide application prospect in the field of education, especially in architectural engineering, archaeology, medical education, tour guide training, history education There is great room for development in chemistry and physics education and social sciences

(II) application in the commercial field

panoramic photography is a practical technology with the advantage of simple system completion. Today, the network bandwidth is still tight, it is a good tool to display quasi 3D graphics on the Internet. However, it is not a real 3D graphics technology after all, and its interactivity is far inferior to virtual reality based on modeling technology. However, it also has broad prospects for development. It can be applied to station construction, multimedia CD making, e-commerce, real estate display, virtual tourism, geographic information system, hotels, virtual exhibitions and other fields

scene and venue display: an immersive experience, which is applied to architectural decoration, hotels, restaurants, KTVs, personalized bars, entertainment cities, golf courses, art galleries, art galleries, museums, exhibition halls, etc

tourism scenery display: generally, people's understanding of scenic spots obtained through brochures is only superficial. Every potential tourism consumer wants to experience the process of scenic spot tour before traveling. The above assumption can be realized through computer virtual technology. It can also be embodied in various forms of touch screen, CD and on-site demonstration

real estate display: it is the best way for businesses to display real estate to users by truly showing the living environment and indoor pattern of the real estate

gis geographic information system: what we are facing is no longer a flat map, but an actual perceptible City: 360 ° panoramic roaming, so that the most representative features of the whole city can be seen. With the powerful GIS geographic information system, the broadband roaming of the digital city can take you to the world

product display: lifelike objects, such as cars, motorcycles, fashion, antiques, jewelry, clocks, works of art, clothing, toys, instruments and equipment, household appliances, etc

investment attraction: the investment attraction environment is displayed in the form of virtual roaming and three-dimensional roaming, and the potential resources can be integrated into other forms. At the same time, the Internet browsing mode makes the tourism investment attraction more user-oriented
