This Small Business Innovation Research Phase II project will further the investigation of two innovative technologies for characterizing fractures in rock masses. The first technology involves image-processing algorithms for the extraction of 3D fracture properties from fracture traces in digital images. The second technology involves the use of laser-scanners to extract the 3D properties of exposed fracture surfaces. The two technologies complement each other well and there are situations where the characterization of fracturing is best analyzed with one or the other or both technologies. The first objective of the Phase II research is to continue to improve the two technologies, and to integrate all the various algorithms into a single user-friendly software tool. The second objective is to thoroughly evaluate sources of error in both technologies through synthetic and field studies, and to develop a set of recommended field procedures and equipment for various applications to optimize the techniques and minimize errors. The third objective is to develop relationships with potential customers for the software and also groups interested in collaborating on software development and validation. Once a beta version of the software is developed, this software will be provided to some customers for validation and assessment.Within the broad scope of the rock engineering market, four distinct market segments have been identified for this innovation. Each market segment has a separate end-use application: mining, geotechnical, petroleum, and environment. Market research and letters of support from various market participants have demonstrated that a market need exists for automation of tasks currently performed manually by rock engineering professionals.

这个小型企业创新研究阶段项目将进一步研究两种创新技术，以表征岩石块中的裂缝。第一项技术涉及图像处理算法，用于从数字图像中从断裂痕迹中提取3D断裂性能。 第二种技术涉及使用激光扫描剂来提取暴露裂缝表面的3D特性。这两种技术相互补充，在某些情况下，最好用一种或两种技术对破裂的表征进行分析。第二阶段研究的第一个目标是继续改进这两种技术，并将所有各种算法集成到单个用户友好的软件工具中。第二个目标是通过合成和现场研究彻底评估两种技术中的错误源，并为各种应用开发一组推荐的现场程序和设备，以优化技术并最小化错误。第三个目标是与潜在客户的软件建立关系，以及有兴趣在软件开发和验证方面合作的小组。一旦开发了该软件的Beta版本，将向某些客户提供验证和评估的软件。在岩石工程市场的广泛范围内，已经确定了四个不同的市场细分市场。 每个市场领域都有一个最终用途的应用：采矿，岩土技术，石油和环境。 市场研究和来自各个市场参与者的支持信表明，市场需求是对摇滚工程专业人员手动执行的任务的自动化需求。
