项目摘要

An image captured on an image sensor chip has an enormous amount of information. It is spatially two-dimensional and, if motion is concerned, it becomes three dimensional because time axis is added. It is almost impossible to perform a real-time recognition of the image by a sequential computation on general purpose computers even if it is the most advanced one of today. The purpose of this research is to develop a basic hardware of integrated-circuit systems that can perform real-time intelligent image recognition. Two integrated circuits have been developed that can real-time detect and trace the movement of an object using a high-functionality device called Neuron MOS transistor (vMOS) as a key circuit element. The processing is conducted on two sets of one-dimensional data obtained by projecting a two-dimensional image data onto x- and y-axs. As a result, it has become possible to detect the motion vector between two successive frames within a few hundred nono secondS,which usually takes about a few tens miliseconds using plural of dedicated DSP chips. We also developed a circuit which can real-time track the position of the center of mass of a moving image. Owing to the vMOS circuit technology, such a processing can be done in several tens nano seconds using a very simple hardware. The characteristic feature of the vMOS integrated circuits is that it accepts analog signals, processing in analog/digital merged hardware computation and yields answers all in digital format. Therefore vMOS circuit technology provides an ideal interfacing between the real world and computer world.

在图像传感器芯片上捕获的图像具有大量信息。它在空间上是二维的，如果考虑到运动，它就变成三维的，因为增加了时间轴。即使是当今最先进的通用计算机，也几乎不可能通过顺序计算来执行图像的实时识别。本研究的目的是开发一种能够进行实时智能图像识别的集成电路系统的基本硬件。已经开发了两种集成电路，可以使用称为神经元MOS晶体管（vMOS）的高功能器件作为关键电路元件来实时检测和跟踪物体的运动。对通过将二维图像数据投影到x轴和y轴上而获得的两组一维数据进行处理。结果，已经可以在几百九秒内检测两个连续帧之间的运动矢量，这通常需要使用多个专用DSP芯片花费大约几十毫秒。我们还开发了一个电路，可以实时跟踪运动图像的质心位置。由于vMOS电路技术，这种处理可以使用非常简单的硬件在几十纳秒内完成。vMOS集成电路的特征在于它接受模拟信号，在模拟/数字合并硬件计算中进行处理，并以数字格式产生所有答案。因此，vMOS电路技术提供了真实的世界和计算机世界之间的理想接口。
