摘要
智能视频监控的核心是对视频内容的分析与检测,将其应用于现有的道路监控视频,可
以准确提供智能交通所需的城市道路交通流量的基础数据,然而现有视频文件格式多样,无
法直接用于 MATLAB 这样的算法实验工具。
本文首先介绍了一个视频分析的算法实验平台的设计与开发。它以海康威视提供的 SDK
为基础, 针对不同道路、不同时段的道路交通视频进行点播,同时通过混合编程的方式将所
需研究的交通道路视频数据传递给 MATLAB 后台,使得算法研发人员可以 MATLAB 环境下,方
便地进行各种类型的道路视频分析算法研究。此外,本文还介绍了一个以算法实验平台为雏
型的算法演示平台的设计与开发,该平台可以对用 C++代码开发出来的算法模块独立调用,
用实际的监控录像测试算法的实用性能,并且以车流量分析算法为例,对该平台的使用进行
了展示。最后,介绍了算法在 DSP 调试阶段涉及到的 RTDX 接口的设计与开发。利用 RTDX 交
互技术,使得 PC 端的程序在不对 DSP 程序进行任何干扰的情况下对算法运行和程序错误进行
观测,大大提高了硬件开发人员的工作效率。

ABSTRACT
The nucleus of intelligent video surveillance technology is the video content
detection and analysis. We can use this technology with road monitoring videos to
provide the exact basic data of urban traffic flow, which plays an important part
of the intelligent transportation system. However, most of road monitoring videos
can’t be opened by MATLAB directly for their special file format.
This paper, firstly, introduces the design and implement of a software platform
named Experimental Platform for Intelligent Video Analysis (EPIVA). The platform is
based on the SDK provided by Hangzhou Hikvision Digital Technology co., ltd., and
it can open the video files of different roads and different time, saved by the
monitoring equipment of Hikvision, with its VOD function. It also can transmit the
necessary video data to MATLAB console by design of mixed programming interface. In
the way, the researchers can do the algorithm research in MATLAB environment with
various kinds of road videos. Furthermore, the paper introduces another software
platform named Demo Platform for Intelligent Video Analysis (DPIVA). DPIVA is based
on framework of EPIVA. It can call the independent algorithm module coded in C++,
and test the performance of the video analysis algorithms with the road surveillance
