Movement Artefacts in Range Images of Time-of-Flight Cameras

Abstract

Modern time-of-flight measuring camera systems are A further problem with these TOF cameras lies in their able to provide accurate depth images but there are problems measurement principle for the dynamic case, as the need to with regard to their usage in a dynamic environment due to their capture a number of phase images in order to compute a measurement principle. The Centre for Sensor Systems recently distance image leads to mixing phase images with different proposed a new 2D/3D camera avoiding this drawback by the relative positions to a scene and thus to erroneous distances or monocular combination of a 2D and a 3D sensor. In this paper, the camera is presented and an approach for detecting erroneous movement artefacts. In ths paper, this aspect shall be discussed, depth values due to movement is made. and a possible solution based on the combination 2D/3D shall be presented.

Lock-in Time-of-Flight (ToF) Cameras: A Survey

“…In [54] a combination of a conventional 2D image sensor and a PMD camera is used in order to detect lateral motion artifacts by means of a classical 2D image edge detector. Instead of discarding the corrupted data, the authors present two possible correction approaches.…”

Stochastic calculus analysis of optical time-of-flight range imaging and estimation of radial motion

“…Early investigations into motion in ToF range imaging examined the detection of motion and use of a dynamic algorithm that reduced the number of frames [2] when motion was detected.…”

Time of flight motion compensation revisited

“…Detect and Repair Methods: Such approaches can be further categorized in methods that operate directly on the depth image using additional inputs such as a foregroundbackground segmentation [3] or additional high resolution cameras [4] and the methods that harness the relation between the raw frames [2,5,6]. In our analysis we restrict ourselves to methods that do not require additional inputs.…”
