【 摘 要 】

On-line measurement of cane bagasse is needed for its utilization. This study aims to investigate effect of the measurement condition of multispectral image for on-line systems. Two main factors (belt speeds and installation angles of light source) influencing the on-line image collection were studied. Four and two levels of the belt speeds (5, 10, 15, and 20 cm/s) and the installation angles (30 and 45°) were specified in this work, respectively. The effect of these two factors on image repeatability was analyzed by ANOVA using a significant level of 5%. The result showed that belt speeds and angles of light source did not influence image repeatability. However, we found that light source angle of 30 degree gave higher precision than 45 degrees
