摘要
以可视化程序开发工具VB为基础,开发了一种路面破损数据采集与评价系统,该系统以CCD摄像机所采集的路面图像为工作对象,强调在数据采集过程中的人机互动。根据公路养护工作的实际需要,对系统的功能进行具体的设计,并阐述了图像显示、图像放大和恢复以及路面损坏范围确定和多边形面积计算等主要关键技术的VB实现过程。实际应用表明,该系统操作简单、运行稳定、数据采集精度高。
Based on developing instruments of visual procedure, this paper proposes a system of data collection and evaluation of pavement dilapidation, which performs upon pavement images acquired by CCD camera and gives emphasis to the interaction of computer and operator. According to the actual requirement of highway maintenance, the paper designs the idiographic system functions and expounds the realization process by Visual Basic, including such key technologies as image display, image enlargement and restoration, confirmation of scope of pavement dilapidation and calculation of polygon area. Test practice proves that the operation is simple and steady and the system is of good practical value.
