网络化等技术的迅猛发展,促使了高速球的特色功能层出不穷。
网络高速球是高速球特色发展的重要分支,是模拟高速球和IP技术融合发展的完美结晶。在高速球基础上,只要增加一块IP模块即可构成一个基本的网络型高速球。在结构上,网络智能高速球最少只需引出电源线与一根网线即可,其布线更加方便。在传输方式上,网络智能高速球通过网络进行传播,传播的是数字信号,传输范围广,容易实现远程接入。
未来技术发展趋势
高清化
随着国际市场和国内市场对于监控系统的普及和大量使用,人们对图像的要求越来越高:从最开始能看到图像,到现在的要清晰的图像,到今后的能进行处理分析的高清晰图像。整个市场高清化的氛围,消费者的需求无疑刺激高清百万像素网络球机等高清技术与产品的快速普及。
传统的网络球主要基于CIF和D1分辨率的视频处理,视频可视范围小,分辨率不足以看清图像细节。高清网络球首先解决了“看得清”的难题,最高达1920×1080的分辨率将视频细节表现得一览无余;其次16:9的视频格式同样解决了“看得广”的难题,相对于4:3的传统监控视频,高清网络编码直接提升了30%的可视宽度,更适合安防监控领域应用。特别是以下场所,高清网络球可以大展拳脚:
1、大型室内监控
非常适合类似球场、会馆、图书馆等大范围的室内场合应用,高清的画质和宽广的可视角度地特点将有利于安保系统的监控。高清网络球甚至可以监控到具体的一个物品的特征,从而保障场馆的安全性。
2、路面、卡口监控
宽阔的路面和卡口往往是传统监控的难题。以一个普通十字路口为例,往往需要3-4个摄像机配合使用才能覆盖,而且由于图像的清晰度不够问题,为了看清一个物体往往需要对镜头拉伸,并需要频繁的转动。高清网络球的出现,可以提供近6倍于传统监控的可视范围和解析能力,直接可以看清画面中的任意局部细节,一般无需对镜头的进行操作。且更宽的可视宽度保证了1-2个摄像机即可覆盖整个路口,减少了监控管理上的负担。
同样对于高速卡口、路面等大场景下监控环境,高清网络球提供了管理者极大的便利性和有效的监控质量。
3、电力系统
适用于发电站、变电所、室外铁塔、高危地区等电力系统视频监控。
4、智能化分析
高分辨率、高清晰度的图像为智能分析提供了无与伦比的图像源,提高后期视频分析的准确度和可靠性。
高清网络球作为一款高性能的编码设备,在应用功能一般主要基于图1所示的四大模块:视频模块、音频模块、编码模块、网络模块。
视频模块:
视频模块主要负责采集高清一体化摄像机的HD-SDI / SDI信号,并进行重建和解码工作,将单线串行的HD-SDI / SDI信号解码成YCbCr数据送至编码模块,数据流如图1-2。如果摄像机直接输出YCbCr数据则此模块可省略。
音频模块:
音频模块由编码和解码组成。前端采集模拟音频信号,包括线形输入和麦克风输入,并解码成IIS数据送至编码模块。解码部分将编码模块完成的IIS数据编码成语音信号,经有源放大输出。
编码模块:
编码模块主要负责视频和音频的编码和解码工作。视频编解码支持H.264、MJPEG编码格式,分辨率最大支持1920×1080,可进行实时High、Main和Baseline profiles的H.264编码。音频编解码支持AAC,MP3、G.711等主流格式。
网络模块:
网络部分兼容10M和100M以太网,负责将音视频数据发送至服务器、存储,支持RTSP等标准网络协议,可进行web操作。
