摘要: 本論文主要探討利用雷射掃描系統量測儲料桶內穀物體積之方法。本系統使用萬能角鐵為機構本體,組成包括雷射掃描儀、微步進馬達、以及電源供應器等,其中步進馬達使雷射掃描儀能夠進行旋轉定位,雷射掃描儀可以測得一維陣列之距離數據。經由三維空間座標轉換系統,可以將雷射掃描儀測得之數據轉換成(X , Y , Z)三維座標。這些座標經由位置的校正以及過濾篩選後,便可建構出儲料桶內部稻穀表面的模型。儲料桶內部稻穀體積之推算,經由程式將所測的點自動連線成三角形和四邊形後,乘上平均高度計算出總體積。另一方式,因儲料桶截面積為圓形或方形,可將面積直接乘上各掃描點之平均高度,即可得到總體積。兩者相較,發現後者之計算誤差均在5 %以內,優於程式自動連線之方式。根據實驗結果,本系統可用來取代人工打點和流量計的計算方式。
This paper focused on the measurement method of grain volume in the storage tank by using laser scanning system. This system consists of a laser scanner, stepping motors, power supply and frame. The laser scanner can be rotated by stepping motor and be used to measure the distance between the observer and the target. The distance data is stored in one-dimensional array. Through the three-dimensional coordinate transformation, the measured date by laser scanner can be converted into three dimensional coordinates(X, Y, Z). After filtering and calibration of the position from these coordinates, we can construct the surface model of the grain in the storage tank. The coordinates of data on the grain surface within the storage tank can be projected on the ground surface. The projected points can be connected into the triangular and quadrilateral shapes automatically by the program, and all areas of the shapes can be multiplied by the average height to calculate the total volume. For storage tank, its shape is either circle or rectangle, and its volume can be simply calculated by multiplying area by average height. The later one is better and the average relative error is mostly less than 5%. According to the results, this system can replace the manual method for estimating storage volume by using laser rangefinder or the flow meter.
