Similar Material Simulation

In the two-dimensional experiment of similar material simulation, three-dimensional coordinate data obtained by total station should be conversed to the coordinate system which is concerned in the experiment.When using bursa-wolf model to converse coordinate,the three rotation parameters should be linearized,which will affect the accuracy of coordinate conversion if the three rotation parameters are big.In this paper,it is researched that using an antisymmetric matrix which is consist of three separate parameters to substitute for the three rotation parameters,and then the lodrigues matrix is composed from the antisymmetric matrix. Conversion results showed that: By introducing of lodrigues matrix, not only the algorithm becomes simple but also the coordinate transformation precision is improved.

Using three dimensional coordinate transformation model with 7 parameters the coordinate transformation parameters are solved. Comparing the coordinates of the kilometer grid point on topographic maps in Beijing54, Xian80 and Urban Independent Coordinate System with the observation coordinates of same point inCGCS2000, Through watching their coordinate changes the moving changes regularity on topographic maps are discovered between Beijing54 and CGCS2000, between Xian 80 and CGCS2000, Urban Independent Coordinate System and CGCS2000

A method for three-dimensional coordinate processing of human motion is presented. The method is well suited for use with opto-electronic data acquisition equipment. A resolution of one part in 500 was achieved over a viewing field of 2.4 m. This resolution was found to be adequate for human gait analysis studies.
