With the development of visual measurement system
Normalize the measured coordinates into the same world coordinate system
Apply in the three coordinate measuring machine(CMM) to have the simulation experiment
So the data normalization has the advantage of more high precision. (2013) Trans Tech Publications
the visual measurement system of single camera which applied in the imaging theory of optical feature points
then get the global data
the result indicates that the maximum absolute tolerance between the normalization coordinates via the center of point set and the ones measured by CMM directly is 0.058mm
Switzerland.
it has been widespread used in the modern production. Due to the limit of the environment in scene
and achieve the overall measurement
the visual measurement system of single camera could not measure the shield between the measured objects each other. Focus on this problem
But the one between the coordinate repeatedly measured at the position of one network control point is 0.066mm
present a kind of the the knowledge of measurement network based on the visual measurement of single camera
set up the measurement network system via the multi-control points. Measure the optical feature points in every network control point via the visual measurement system of single camera

The traditional Hausdorff measure, which uses Euclidean distance metric (L2 norm) to define the distance between coordinates of any two points, has poor performance in the presence of the rotation and scale change although it is robust to the noise and occlusion. To address the problem, we define a novel similarity function including two parts in this paper. The first part is Hausdorff distance between shapes which is calculated by exploiting shape context that is rotation and scale invariant as the distance metric. The second part is the cost of matching between centroids. Unlike the traditional method, we use the centroid as reference point to obtain its shape context that embodies global information of the shape. Experiment results demonstrate that the function value between shapes is rotation and scale invariant and the matching accuracy of our algorithm is higher than that of previously proposed algorithm on the MEPG-7 database.

The simulation methods for the adaptive optics (AO) system are studied. Based on the global structure of the AO system
the key principles for each module are first discussed systematically
including the wave propagation principles
wave-front representation
coordinates transformation between the coordinates considered
wave-front reconstruction algorithm and DM principles. The purpose of these discussions is to establish the theoretical foundations for the numerical simulations of the AO system. Then the simulation steps are described in detail and a series of numerical simulation results are given which validate the effectiveness of our simulation work. 2012 Chinese Assoc of Automati.

There are some limitations when environment model of AS-R mobile robot is obtained by only using a separate CCD camera or ultrasonic sensor array. The BP neural network is designed to fuse information of the two sensors to obtain the robot's environment model in this paper. The input of BP neural network is the intercept and slope of the edge line obtained CCD camera and ultrasonic sensor arrays
which is processed by through the global coordinates of coordinate transformation. The output of BP network is the fused intercept and slope of the straight edge. Experiment shows that environment model is feasible for the AS-R mobile robot and the environment modeling method has more reliability and accuracy. 2010 IEEE.
