求助!Java web 调用本地摄像头100分 是这样,我想在一个网页的登录界面调用摄像头,然后进行人脸识别.我想问的是如何利用Java技术来调用本地摄像头呢?在一个jsp页面上如何实现呢?我的QQ1390729063,例如在eclipse下需要什么jar包.请详细说明.如有代码,感激不尽!Java摄像头技术Java Web 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 参考;http://blog.csdn.net/china_lzn/article/details/7553552 //利用这三个类分别获取摄像头驱动,和获取摄像头内的图像流,获取到的图像流是一个swing的component组件类public static player player = null;private capturedeviceinfo di = null;private medialocator ml = null;//文档中提供的驱动写法,为何这么写我也不知:)string str1 = "vfw:logitech usb video camera:0";string str2 = "vfw:microsoft wdm image capture (win32):0";di = capturedevicemanager.getdevice(str2);ml = di.getlocator();try{ player = manager.createrealizedplayer(ml); player.start(); component comp; if ((comp = player.getvisualcomponent()) != null) { add(comp, borderlayout.north); }}catch (exception e){ e.printstacktrace();}//接下来就是点击拍照,获取摄像头内的当前图像。//代码也是很简单:private jbutton capture;private buffer buf = null;private buffertoimage btoi = null;private imagepanel imgpanel = null;private image img = null;private imagepanel imgpanel = null;jcomponent c = (jcomponent) e.getsource();if (c == capture)//如果按下的是拍照按钮{ framegrabbingcontrol fgc =(framegrabbingcontrol) player.getcontrol("javax.media.control.framegrabbingcontrol"); buf = fgc.grabframe(); // 获取当前祯并存入buffer类 btoi = new buffertoimage((videoformat) buf.getformat()); img = btoi.createimage(buf); // show the image imgpanel.setimage(img);} 保存图像的就不多说了,以下为示例代码bufferedimage bi = (bufferedimage) createimage(imgwidth, imgheight);graphics2d g2 = bi.creategraphics();g2.drawimage(img, null, null);fileoutputstream out = null;try{ out = new fileoutputstream(s);}catch (java.io.filenotfoundexception io){ system.out.println("file not found");}jpegimageencoder encoder = jpegcodec.createjpegencoder(out);jpegencodeparam param = encoder.getdefaultjpegencodeparam(bi);param.setquality(1f, false);//不压缩图像encoder.setjpegencodeparam(param);try{ encoder.encode(bi); out.close();}catch (java.io.ioexception io){ system.out.println("ioexception");} 额,问题已经解决了,直接使用html5 就OK了.不管怎么说,非常感谢你.. onMouseOver="nav1.style.display='block';"怎么在firefox失效 Ext dataIndex JS提交表单到数据库 麻烦帮忙解决一下这个奇怪的问题,在线等 使用recordset提高数据库查询结果向前端推送数据的效率 在同一个页面上,能否实现一个button有多个链接到不同frame 急求弹出查询的解决方案,要不然国庆节后期都没有玩了,呜呜呜 小弟出来咋到,来者有分 高手帮忙!关于超链接! JAVAWEB框架变形了咋解决呢? ExtJS表单提交时报错 js拖动div会受到div bottom样式的影响吗?
