| 摘 要： | 提出采用计算机立体视觉法对锅炉煤粉仓粉量进行测量,该方法采用立体视觉空间曲面重建技术,通过对三维曲面表面成像进行边缘提取、图像匹配、匹配点空间位置计算等步骤,得到煤粉仓粉堆表面点的空间位置,利用空间点信息对锅炉煤粉仓粉堆表面进行恢复,从而测得存粉量.还讨论了立体视觉系统的摄像机分辨率、测量范围和摄像机间距等参数之间的关系,对立体视觉测量精度进行分析,并推导出重要结论.利用该方法对堆积物表面形状及体积测量实验,由实验结果可知本方法能准确、快速、方便地对煤粉仓粉量进行测量.

| Abstract: | In this paper,computer stereo system is present for coal measurement in boiler coal bunker.The method utilizes the correlation of image captured by camera from multiple view points to reconstruct the coal surface,the reconstruction process mainly includes the following steps: image capture,camera parameters calibration,character extraction,image matching,space point determination and interpolation.The relationship between camera resolution,metrical area and distance between two camera is derived and important result is achieved.In lab,the precision of stereo vision is analyzed by accumulation that the volume of accumulation is known.The experiment result shown that stereo vision system can get level of coal in boiler coal bunker more quickly,nicety and facility. |
