    • When an image is captured in a wood lumber measuring mode, a distance to wood lumber is detected. An area extracting unit 51 for a component drawing image area extracts component image areas 53A-53L of the wood lumber. A drawing generator 61 for a component drawing image selects the component image areas 53A-53L successively to generate a component drawing image 62. Among shape lines in the component drawing image 62, an eliminator 66 eliminates a paracentral shape line 71, an edge side shape line 72, a peripheral shape line 73 and determined shape lines 74. If a total pixel number of a portion where an estimated elliptical shape 76 generated by a shape estimation unit 67 is overlapped on a residual shape line 75 disposed inside a corrected drawing image 64 is more than a threshold, it is judged that the estimated elliptical shape 76 is correctly shaped. An object shape determining unit 83 extracts the estimated elliptical shape 76 as a shape of wood lumber. A size measuring unit 84 measures a size of the estimated elliptical shape. A size determining unit 85 determines an actual size of the wood lumber according to the size measured by the size measuring unit 84, the distance to the wood lumber and a focal length.
    • 当以木材木材测量模式捕获图像时,会检测到木材的距离。 用于分量绘图图像区域的区域提取单元51提取木材的分量图像区域53A-53L。 用于分量绘图图像的绘图发生器61连续地选择分量图像区域53A-53L以产生分量绘制图像62.在分量绘制图像62中的形状线中,消除器66消除了副中心形状线71,边缘侧形状 线72,外围形状线73和确定的形状线74.如果由形状估计单元67生成的估计的椭圆形形状76的部分的总像素数与设置在校正绘图图像64内的残留形状线75重叠 判定为椭圆形状76是正确的形状。 物体形状确定单元83将估计的椭圆形状76提取为木材的形状。 尺寸测量单元84测量估计的椭圆形状的尺寸。 尺寸确定单元85根据由尺寸测量单元84测量的尺寸,与木材的距离和焦距来确定木材的实际尺寸。
