An Evaluation of Time-of-flight Range Cameras for Close Range Metrology Applications
Time-of-flight range cameras are an emerging technology that produces a digital photo or video like output in which every pixel contains both intensity and distance information. Typical currently available off-the-shelf range imaging cameras offer spatial resolutions of up to 40 k-pixels, distance measurement precision of less than 1 cm, and accuracy of a few centimetres. These specifications s...
متن کاملTime-of-Flight Cameras in Computer Graphics
A growing number of applications depend on accurate and fast 3D scene analysis. Examples are model and lightfield acquisition, collision prevention, mixed reality, and gesture recognition. The estimation of a range map by image analysis or laser scan techniques is still a time-consuming and expensive part of such systems. A lower-priced, fast and robust alternative for distance measurements are...
متن کاملTime-of-Flight Cameras and Microsoft Kinect
Well, someone can decide by themselves what they want to do and need to do but sometimes, that kind of person will need some time of flight cameras and microsoft kinect references. People with open minded will always try to seek for the new things and information from many sources. On the contrary, people with closed mind will always think that they can do it by their principals. So, what kind ...
متن کاملQuantifying the Distortion of Distance Observations Caused by Scattering in Time-of-flight Range Cameras
Time-of-flight range cameras simultaneously gather object distances for all pixels of a focal plane array by evaluating the round-trip time of an emitted signal. In contrast to competing techniques, cameras combining continuously emitted, amplitude modulated signals and Photonic Mixer Devices (PMD, lock-in pixels) to derive signal phase shifts and hence object distances, have reached mass produ...
متن کاملTheoretical and Experimental Error Analysis of Continuous-Wave Time-Of-Flight Range Cameras
This paper offers a formal investigation of the measurement principle of time-of-flight (TOF) 3D cameras using correlation of amplitude-modulated continuous-wave signals. These sensors can provide both depth maps and IR intensity pictures simultaneously and in real-time. We examine the theory of the data acquisition in detail. The variance of the range measurements is derived in a concise way a...
