摘要
煤炭地质强度因子(GSI)是煤矿工程中一个重要参数,反映了煤体强度的稳定性。使用Android Studio软件开发设计了基于Android手机平台的煤炭地质强度因子(GSI)检测系统、将煤炭样本制成相应规格的煤心后,通过手机拍照或相册获取煤炭图片,然后对其进行图像处理后得到煤炭裂隙图,再根据分形维数对煤炭裂隙图进行处理即可计算出GSI数值,并能即时显示检测结果。利用Java语言和OpenCV计算机视觉库在Android手机上实现煤炭GSI图像处理与检测。结果表明:通过该系统获得的GSI数值与实际数值具有线性拟合关系且误差较小,检测时间小于5 s,大幅缩短了GSI数值确定的时间,减少传统人工测定产生的差异,对煤矿勘探和开采具有一定的实际应用价值。
Coal geological strength index(GSI)is an important parameter in coal mine engineering,which reflects the stability of coal strength.This paper uses Android Studio software to develop and design a coal geological strength index(GSI)detection system based on Android mobile platform.After the coal sample is made into the coal core of the corresponding specification,the coal pictures are taken by mobile phone or photo album,and then the coal fracture image is obtained after image processing,and then the GSI value can be calculated by processing the coal fracture image according to the fractal dimension,and the detection results can be displayed in real time.Using Java language and Open CV computer vision library to realize coal GSI image processing and detection on Android mobile phone.The results show that the GSI value obtained by the system has a linear fitting relationship with the actual value,and the error is small,the detection time is less than 5 seconds,which greatly shortens the time of GSI value determination,reduces the difference of traditional manual measurement,and has a certain practical application value for coal exploration and mining.
