Development of Digital Automatically Analysis Technique for Maceral Specification

The development of digital automatical analysis technique for maceral specification is the result of coordination of several sciences. The measurement precision of maceral reflectance is increased due to the extended gray grads using high precision digital camera of alterable exposure-time. The maceral recognition is automatically carried out with high resolution micro-image and image recognition technique. The quick automatical analysis for maceral specification is implemented with the auto-scan and the auto-focus. For this technique, the disadvantages and advantages of microscopic photometer and the image analysis apparatus are overcame and inherited respectively making the measurement results more reliable. The training course for operators is quite moderate.
