Usual programming is set making courses extra greatly appropriate through unique forms of parametrization---not simply alongside the size of values or of varieties, but in addition of items similar to the form of information, algebraic buildings, techniques, computational paradigms, and so forth. listed programming is a light-weight kind of dependently typed programming, constraining flexibility by way of permitting one to country and cost relationships among parameters: that the shapes of 2 arguments agree, that an encoded worth fits a few sort, that values transmitted alongside a channel comply with the acknowledged protocol, etc.

Example text

The latter choice of baseline is not constant, resulting in a more complicated computation model for the reason that the lengths between rotation centers and optical centers are less easy to estimate. 2 Depth Calculation We use a simplified model for the depth calculation as shown in Fig. 2 x PZ Zc M el M M Z T Tl r br bl er baseline Fig. 2. e. eye, camera and object are aligned without rotation and translation, we can easily derive the following equations: tan(θl ) = Z bl (11) tan(θr ) = Z br (12) b = bl + br (13) b 1/tan(θl ) + 1/tan(θr ) (14) From (11), (12) and (13), we have: Z = where b = er − el is the baseline, θl and θr are the left angle of the left eye axis and the right angle of the right eye axis, respectively.

Moreover, depth calibration is applied to improve 3D ToF camera measurements following the methodology of [7]. All together helps to get more accurate point clouds and to correctly register them in order to make the model grow. 2 Results The Zeus, Mozart and Camel objects are appropriate for the evaluation because they have been used previously in other works. Moreover, the obtained results can be compared with two previous approaches used at DLR in the past (Fig. 6). Although a straightforward comparison between them is not an easy task because each approach used different sensors, some interesting conclusions can be extracted.

5 with Fig. 4, the validity of our model as well as the depth calculation algorithm is shown. 2 Experiment 2 Experiment 2 investigates the influence of the object positioning accuracy on the depth error. First, we introduce the definition of positioning accuracy. Given the image center, we track the projected image point of an object inside a window of the size ε around the image center. We call ε the positioning accuracy. The smaller ε, the more accurate the positioning. As shown in Fig. 6, the depth error drops significantly when the positioning accuracy increases 10 times, whereas after this threshold, the improvement of 34 X.
