我们一直在开发一种快速原型显示系统，可以验证最终产品的外观在整理和油漆行业。在该系统中，需要测量手的位置和形状的详细信息，以识别工人的指令。因此，我们采用了一种联合收割机，它结合了红外投影和空间编码的方法来粗略检测手部的位置和形状。对于手部位置的检测，非线性间隔条用于检测低于恒定高度的物体。设计了与摄像机光轴夹角有关的条纹间距，使检测时的高度相等。对于手形检测，时间和空间编码图案仅投影手位置的区域。这个测量是足够粗略的，因为我们的原型显示系统只需要分类跟踪，触摸，推动和采摘的形状。因此，在有限区域内的有限过程可以非常快速地重建手的形状。一个实际的结果表明，位置和形状的识别是执行约一秒钟，和操作员评论说，这样的时间延迟不会成为一个压力，因为实际的手操作。
We have been developing a rapid proto-typing display system which can verify an appearance of final product in finishing and painting industry. In this system, it is necessary to measure detail information of hand position and shape to recognize the worker's instruction. Therefore, we apply a rapid hand measurement which combine a roughly detecting of hand position and shape by spatial encoding method with IR projection. For detecting of hand position, non-linearity interval strips are used for detecting objects that are lower than constant height. The interval of strips is devised in relation to an angle of camera axis to make equal the height in detecting. For detecting of hand shape, the temporal and spatial encoding pattern is projected only an area of hand position. This measurement is enough rough because our prototyping display system need only to classify the shape of tracing, touching, pushing, and picking. Therefore, the limited process with limited area is possible to reconstruct the shape of hand very fast. A practical result shows that the position and shape recognition is performed about one second; and operator comment that such the time delay doesn't become a stress as for actual hand operation.
