Development of Reconstruction Method for Highly Precise Shave-Off Depth Profiling

Calibration Method Evaluation via Depth Reconstruction

This paper presents a fast method to evaluate the accuracy of a calibration method of a stereovision rig built with commercially available cameras. The method allows by retro projection to quantify very precisely errors in terms of depth reconstruction. The proposed method has been evaluated on the depth reconstruction of real scenes from images taken with an unmanned aerial vehicle.

Questioning Lead Standards: Even Low Levels Shave Points off IQ

The study of the health workforce has gained in prominence in recent years, as the dynamic interconnections between human resource issues and health system effectiveness have come into sharper focus. This paper reviews lessons relating to strategic management challenges emerging from the growing literature in this area. Workforce issues are strategic: they affect overall system performance as w...

A Direct Method for Hand-Eye Calibration and Depth Reconstruction

A method for hand-eye calibration using only normal ow measurements, i.e. only the spatial and temporal intensity derivatives in an image sequence, is presented. As a bi-product we will recieve an approximate depth map of the current scene. The method does not rely in any stage on the detection and matching of features and is in no need of a special calibration object. The method is an active r...

Development of a Depth Profiling Technique Using Diffuse Reflectance

Recent developments in FT—IR sampling techniques such as diffuse reflectance and photoacoustic spectroscopy are known to obtain new and novel information on solid polymers. In particular, depth profiling can be obtained from the surface using a potassium bromide overlayer. Photoacoustic spectroscopy using coupling gases with different polarizability allows one to determine the nature of absorbe...
