چکیده
Structured light surface scanners are usually limited to a single projector and cannot provide full profile in scan. Multiple projectors must be employed extend the imaging area over whole of imaged object. Using multiple is challenging problem due inter-projector interference which make pattern decoding hard. We describe practical approach multi-projector structured scanning based on sinusoidal fringe patterns temporal phase shifting allows simultaneous employment. In our different set shifts assigned each enable efficient robust separation observed combined into contributions projector. The proposed does not place any restrictions placement nor upper limit number used. demonstrate applicability scanner comprised three six cameras.

High-Resolution Structured Light Range Scanner with Automatic Calibration
In this work, we present a low-cost high-resolution structured light range scanner with automatic calibration, based on temporal stripe encoding. We present a novel single-step automatic active stereo calibration method, based on optimal backprojection estimation. We also present a method for estimating local fidelity of the range image and show how this information can be used to obtain sub-st...
متن کاملAssessing the Performance of a Structured Light Scanner
An alternative to the mostly known and market dominating laser scanners are Structured Light scanners. Structured light 3D scanners project a pattern of light on the object and detect the deformation of the pattern on the object. They are basically non-contact optical systems, based almost entirely on the principles of photogrammetry in order to transform image pairs to surface information. The...

متن کامل3D Facial Surface Acquisition by Structured Light
This paper presents a 3D acquisition system based on structured light and adapted to 3D facial capture. It was developed in the framework of automatic face recognition with practical constraints so that the design followed speed, low cost and resolution requirements. A single shot with correct posture is suucient to capture nearly the whole facial surface in half a second. The system has been t...
متن کاملRobust Automatic Surface Reconstruction with Structured Light
For the measurement of surfaces of close range objects, which do not show sufficient surface texture, an automatic system based on the projection of structured light has been developed. An off-the-shelf slide projector projects chromium slides with a regular dot pattern of 800 ... 8000 dots and perfectly binary transparency characteristics onto a surface. For robust point determination the obje...
