之前有需求想把krpano功能化,让后台全自动生成,但是在网上并没有看到相关的帖子,于是我就对krpano研究了一天,总算给实现了,随着VR的发展,这项技术肯定会有更多的人学习,我就把我研究出来的解决过程分享给大家吧!!!<a href=java全自动生成krpano全景漫游" alt="微笑" src="http://static.blog.csdn.net/xheditor/xheditor_emot/default/smile.gif">

准备工作:

  1.下载krpano-1.19-pr8(我用的是这个版本),下载地址:https://krpano.com/download/,至于破解我就不讲了,网上有很多

2.java开发环境

3.tomcat

原理:下载krpano后解压文件夹里有一个批处理:MAKE VTOUR (MULTIRES) droplet.bat,直接把全景图片拖动执行这个批处理就会自动生成相应的全景html文件夹。

废话不多说,直接上码:

这些代码主要意思是用代码来拖动全景图片去执行那个批处理,然后等待生成之后修改生成之后的文件以及删除一切多余的文件,因为我做过N次实验及对比,我发现执行后生成的很多文件都是一致的,所以我就整理了一个通用的包(放在vshow文件夹),因为生成文件后必须还得自动发布,所有vshow这个文件夹我是直接放在项目里的:

java全自动生成krpano全景漫游

至于vshow里的文件内容你自己生成一次之后保留这些东西就可以了,继续回到正题,我这个是将全景图片上传了之后,先存放在D:\\temp-room\\里,然后执行cmd命令自动生成,生成了之后将需要的文件复制到vshow文件夹里,只要你仔仔细细看我代码就能明白所有的事情,生成这些文件处理完后,前台访问就直接用一个通用的jsp文件来访问,直接贴上我的源码吧,一定要仔细看代码,不然真的很难懂:
