主动视觉中番茄定位特征照射光源的实验研究

在基于主动视觉的番茄定位实验中,需要利一个优质照射光源在被定位的番茄表面形成精确的匹配点,从而重建番茄可见光照射部分的曲面,进而找到曲面中心来确定在遮挡与重叠等情况下番茄的位置。为此,以成熟的番茄为研究对象,对主动视觉中番茄定位实验采用的特征照射光源进行了试验研究,发现在各种单色光中,使用红色光照射,并且通过对图像中的蓝色分量进行分割,既能有效地排除噪音又能精确地确定目标点的位置。

Experiment Investigation on Labeling Exposure Light Source in Active Vision Tomato Position

In the tomato position experiment base on active vision technology, a high-quality illumination is need to find a precise matching point on the loathed tomato surface, which is used to reestablish the curved surface of tomato shined by illumination, so as to find the center of curved surface for determining the position of tomato. Hence, this paper regards mature tomato as the research object, and studies the label projecting light source demanded of active vision tomato position experiment, finding in every kind of color monochromatic light, by use of the red light irradiation, and segmenting the blue component of the picture, can both expel the noise availably and position target point accurately.
