Low-cost 3D image capture devices are enabling new applications in the gaming, robotics, automotive and surveillance industries. A number of approaches are competing for a share of these markets. Stereoscopic cameras employ intensive image processing to interpret distance from the correlation of two separate image streams [1], structured light systems analyse the deformation of pat terned light projected...
Conventional cameras capture 2D photographs at a single plane of focus. Acquisition of a 3D photograph with multiple planes of focus typically requires scanning the focus of a single camera, or using arrays of cameras or lenses. This paper demonstrates a 150kpixel image sensor, which captures 3D scenes. The chip is manufactured in commodity 0.18μm CMOS and requires only a single convex lens at a fixed...
In order to search and rescue the victims in rubble effectively, a 3D model of the cavity is required. This paper presents a cavity detection method based on machine vision for disaster rescue robot. Laser ring projection technique is developed to lighten the profile of cross-section of the cavity and draw a line around the internal surface. A CMOS camera is used to capture the images which consist...
External sensing applications in automobiles are enabled by Microsystems that can sense and analyze 3D environment. In this paper, we describe the system design of a time-of-flight (TOF) 3D range camera for parking assist and backup application. The camera operates based on measuring the time delay of modulated infrared light from an active emitter, using a single detector chip fabricated on standard...
