【摘要】 在总结了半个多世纪对爆堆矿岩块度分布分析的测试方法的基础上，着重研究了最新的测试方法――爆堆矿岩块度分布自动与分形测试系统，该系统处理的照片必须是垂直爆堆斜面拍摄得到，从而降低了数据采集人员的安全性，增加了数据的采集的工作量，延长了数据处理周期。针对该系统的这点不足，改照片垂直爆堆斜面拍摄为水平拍摄。对得到的几何畸变图像，应用结合分形理论，数量统计和计算机图像处理技术开发的扭偏子系统进行处理，恢复到垂直爆堆斜面拍照的状态。对扭偏子系统进行必要的精度检验，证明在保证测试精度的前提下，扭偏子系统能够解决自动与分形测试系统的不足。本文的创新之处，将适用于二维平面几何畸变图像的恢复处理技术同分形理论及爆堆矿岩的分形特征紧密结合，提出了对爆堆采用水平方向进行拍照，对畸变图像进行扭偏处理，使其能够准确反映爆堆矿岩的整体块度分布情况。更多还原

【Abstract】 On the base of summarized and pile ore is distribute method of testing analysed by rock each producing over half a century, have studied the last method of testing emphatically-- Produce and pile ore distribute automatically and fractal by rock each. The photo who system deal with must have been perpendicular to produce and pile inclined plane shoot and receive, thus reduced the data and gather personnel’s security, have increased the work load gathered of the data, has extend data processing period. Directed against the shortcoming of the system, change photos to produced and piles the inclined plane and shot and shot for the level perpendicularly. To the geometry distortion picture that is received, deal with it combines and fractal theory, mathematical statistics and computer pattern process technological the sprain subsystem of leaning towards with development. Resume the perpendicular state that produce and pile the inclined plane and takes a picture. Carry on the essential precision to examine in spraining the subsystem of leaning towards, prove that base on the premise that guarantee to test the precision, the spraining subsystem of leaning towards can be solved and test the systematic deficiency with the shape of dividing automatically.The place of innovation of this text, combine closely suitable for two-dimentional plane distortion picture of geometry deal with technology with fractal theory and produce and pile ore fractal characteristic by rock, have propose and take a picture in producing and pile and adopt the horizontal direction, Sprain simply deals with to the distortion picture , make it can reflect that produce pieces of distribution situation of whole which piles the rock of ores accurately .更多还原
