3D scene capturing using stereoscopic cameras and a time-of-flight camera

Depth Map Improvement by Combining Passive and Active Scanning Methods

“…We can observe two paths of development, namely active and passive 3D capturing systems. Active capturing systems utilize the projection of the measurement pattern on a scanned scene which could be in visible light spectrum [1], [2], near infrared field [3] or projected by a focused laser spot [4]. In the mostly used passive system, the depth of the pixel is determined from its disparity in a stereo pair.…”

“…Some part of current 3D video shooting systems is based on combinations of more depth acquisition methods, such as Time-of-Flight (TOF) IR camera with a stereo pair, where a depth image is rectified to the color camera images [2]. In some other approaches, the stereo pair is fructified by combining advanced and conventional methods of image segmentation [9], or more monocular cues are combined to estimate the depth map [10].…”

A depth video processing algorithm based on cluster dependent and corner-ware filtering

“…Currently, depth video can be obtained by using time of flight (ToF) based depth camera [5] [6], Kinect sensor [7] and depth estimation software [8]. However, due to the limitation of these depth video capturing techniques, depth video is inaccurate and inconsistent.…”

Dynamically adaptive real-time disparity estimation hardware using iterative refinement

“…A TOF camera easily measures the distance between the object and camera using a sensor, circumventing the need of intricate digital image processing hardware [10]. However, it does not provide efficient results when the distance between the object and camera is high.…”

“…However, it does not provide efficient results when the distance between the object and camera is high. Moreover, the resolution of TOF cameras is usually very low (200 Â 200) [10] when it is compared to the Full HD display standard (1920 Â 1080). Furthermore, their commercial price is much higher than the CMOS and CCD cameras.…”
