    • PROBLEM TO BE SOLVED: To provide a method and system which is capable of measuring particle sizes of muck piles immediately after blast, at the face immediately after blast.SOLUTION: A plurality of scales 10 which emit infrared light with a prescribed intensity and have a prescribed size are placed on deposits of blast muck piles 3 at a face 1 which have occurred by rock blasting drilling, and a temperature distribution image Q of the deposits of muck piles 3 including the scales 10 is picked up by an infrared camera 20, and profiles of respective muck piles 3 and scales 10 are extracted from the temperature distribution image Q, and particle sizes of respective muck piles 3 are measured by the profiles and the prescribed size of the scales 10. Preferably, a plurality of temperature distribution images Q1 to Q4 are picked up in time series from one viewpoint P by the infrared camera 20, and profiles of respective muck piles 3 and scales 10 are extracted from the plurality of images Q1 to Q4 by an image processor 25. For example, the temperature distribution images Q1 to Q4 are picked up while continuously blowing the deposits of muck piles. Preferably, one end of a string 15 having a required length is attached to each scale 10, and the scale can be placed on the deposits by throwing.
    • 要解决的问题:提供一种方法和系统,该方法和系统能够在爆炸后立即测量爆炸后的面积上测量粪堆的粒径。 解决方案:将通过规定强度发射红外光并具有规定尺寸的多个鳞片10放置在通过岩石钻孔发生的表面1处的鼓粉堆3的沉积物上,并且将温度分布图像Q 由红外摄像机20拾取包括鳞片10的堆积桩3的沉积物,并且从温度分布图像Q中提取相应的堆积桩3和鳞片10的轮廓,并且通过以下方式测量各个堆积桩3的粒径 轮廓和规定的尺寸。优选地,通过红外摄像机20从一个视点P以时间序列拾取多个温度分布图像Q1至Q4,并且提取相应的堆积桩3和鳞片10的轮廓 通过图像处理器25从多个图像Q1至Q4。例如,在连续吹送堆积的堆积物的同时拾取温度分布图像Q1至Q4。 优选地,具有所需长度的弦15的一端附接到每个刻度10,并且刻度可以通过投掷放置在沉积物上。 版权所有(C)2012,JPO&INPIT
