Latest System

A integrated vision system with frame-rate output is proposed with the high-speed camera and FPGA hardware architecture, which is vary useful in the micro operation. In our past work, we had proposed the system which could obtain the "all-in-focus image"' and the "depth" of object, simultaneously. Actually, in micro operation, such as for the micro-surgery, DNA operation and etc., the small depth of a focus on the microscope makes bad observability. In this sense, the "all-in-focus image", which holds the in-focused texture all over the image, is useful to observe the micro environments with the microscope. It is also impor-tant to obtain the depth map, and to show the 3D micro virtual environments in real-time to actuate the micro objects, intuitively. The past system with dynamic focusing lens and the smart sensor could obtain the "all-in-focus image" and the "depth" in 2 sec. To realize the real-time micro operation, at least, 30fps (60 times faster than the past) system should be required. In this paper, the system captures and processes the images with 240fps, and integrates eight images into one, i.e. frame-rate; 30fps output.

Past System

In this research, a real-time observational sensor system for the tele-micro-operation has been proposed with a dynamic focusing lens and a smart vision sensor using the ``depth from focus'' criteria. On the operation of micro objects, such as the micro-surgery, DNA operation and etc., the small depth of a focus on the microscope makes bad observability. For example, if the focus is on the object, the actuator could not be seen with the microscope. On the other hand, if the focus is on the actuator, the object could not be observed. Then, the ``all-in-focus image'', which holds the in-focused texture all over the image, is useful to observe the micro environments with the microscope. However, one drawback on the all-in-focus image is that there is no information about the depth of objects. It is also important to show the 3D micro environments in real-time to actuate the micro objects with the micro virtual environments. This paper discusses, firstly, the criteria of ``depth from focus'' to achieve the all-in-focus image and the 3D micro environments' reconstruction, simultaneously. Then, a real-time VR micro camera system has been proposed to achieve the micro VR environments with the ``depth from focus'' criteria. This system is constructed with a dynamic focusing lens, which could change the focal distance of lens in high frequency, and a smart vision system, which is capable in capturing and processing the image data in high speed with SIMD architecture.
