It describes the color characteristic of device accurately through constructing the geometric model and builds gamut mapping model in the section plane of gamut by dissecting. The improvement of image characteristic obtaining at real time satisfies the application and supports the adaptive gamut mapping. The sampling and visualization of sample set in different color space show the optic difference and give the error analysis of the color conversion between them. Based on the study of the color relation among the color spaces, the visualizing color can be created automatically with conversion formulas.

Firstly, the soil samples are gathered from the same section such as surface layer soil samples gathered from 0cm to 15cm depth and representation on studied object. Secondly, the precondition of tested samples must be the same. This study indicates that the tested samples must be 1mm diameter, over-dried at 40℃ for 24h and airtight cooling for 24h before measured for air-dry samples, and softly planish the surface at measuring. Lastly, the illuminating condition of light must be the same. This study indicates that the testing geometric condition are light source angle 15°, light source distance 30cm and sensor distance 15cm for soil hyperspectra indoor. The surface of white reference must be the same plane of that of sample.

In the second part, we developed a new approach for the preparation of highly dispersed carbon black platinum nanoparticle with different geometric shapes by introducing clay (0 to 33%) as a dispersing agent in 5% Nafion co-solvent suspension without any organic solvents. FE-SEM analysis of CB/clay (100/0, 85/15, 67/33) was achieved CB particles with an average diameter of 40-60 nm. The hydrophilic property of the hybrid material was effectively improved in the presence of the clay was observed in sessile-drop test.

In this paper, we give explicit constructions and formulations for harmonic maps from R1,1 into classical real semisimple Lie groups by using Darboux transformation. We also discuss pluriharmonic maps from complex manifoldsinto symmetric spaces and Willmore surfaces in Sn. By converting geometric conditions satisfied by these maps into integrable systems, and using the the-ory of integrable systems, we give explicit constructions for pluriharmonic maps from complex manifolds into symmetric spaces and the Willmore surfaces in Sn respectively. Finally, we classify hypersurfaces in Sn+1 with three distinct prin-ciple curvatures and zero Mobius form using the theory of Mobius geometry. The paper consists of four chapters.

The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

Specifically, we apply the polar form in the conversion between triangular Bezier surfaces and rectangular Bezier surfaces. This problem helps us to understand the theory of polar form in a unified way. At the last half of this paper, we consider the problem of geometric continuity of parametric curves and parametric surfaces.
