摘要：Three dimensional (3D) range cameras measure 3D point clouds and intensity information of objects using time-of-flight methods with a CMOS/CCD array. Their emerging applications are security, surveillance, bio-mechanics and so on. Since they comprise a CMOS/CCD array, a nearest-neighbor search for individual points is not necessary, which can increase the efficiency in estimating the geometric properties of objects. This fact leads us to broaden the application areas of 3D range cameras to real-time and dynamic applications such as mobile mapping and vehicle navigation. This paper presents extensive metric performance tests of a 3D range camera (SwissRanger SR-3000). It is composed of a 176x144 pixel CMOS array for which the pixel size and spacing are both 40 μ m. The nominal principal distance of the lens is 8mm. Several rangefinder system parameters such as the integration time and the modulation frequency can be set by the user. For example, the shorter integration time is maximising the signal-to-noise ratio. In addition, the maximum unambiguous range is 7.5m with the modulation frequency of 20MHz
