我们描述了一种使用多个图像传感器和镜子的宽视角成像系统。在该系统中，真实的多个传感器获得的每个图像相当于一个虚构的传感器获得的图像。因此，不需要从传感器到图像中的每个对象的深度估计。在本文中，我们提出了使用我们设计的随机访问图像传感器的宽视角成像系统。该系统的电路由传感器和 FPGA 组成。它可以实时捕获并显示全景图像或任意视图图像。新的图像传感器具有128 x 128像素，具有随机存取、以四分之一间距插值像素值、设置固定数字作为传感器识别以及放大像素值以减少传感器之间的差异的功能。我们展示了该芯片获得的一些结果。未来，我们将进一步测试所提出的芯片，并提出具有八个摄像头的全景成像系统。
We describe a wide view imaging system using multiple image sensors and mirrors. In this system, each image obtained by real multiple sensors is equivalent to the image obtained by an imaginary sensor. Therefore depth estimation from sensor to each object into the image is not required. In this paper, we propose the wide view imaging system by using random access image sensors we have designed. The circuits of the proposed system consist of the sensors and FPGA. It can capture and display panorama view image or arbitrary view image in real time. The new image sensor has 128 x 128 pixels and the functions of random access, interpolation of pixel values on quarter pitch, setting fixed number as sensor identification and amplifying pixel value for reduction of variation between sensors. We show some result obtained by the chip. In the future, we'll test the proposed chip further and propose panorama view imaging system with eight cameras.
