Abstract:
The invention provides a La(Fe,Si)13-based magnetic refrigeration material prepared from industrial-pure mischmetal as the raw material, wherein the industrial-pure mischmetal is impurity-containing and naturally proportionated La—Ce—Pr—Nd mischmetal or LaCe alloy which, as the intermediate product during rare earth extraction, is extracted from light rare earth ore. The invention further provides the preparation method and use of the material, wherein the preparation method comprises the steps of smelting and annealing industrial-pure mischmetal as the raw material to prepare the La(Fe,Si)13-based magnetic refrigeration material. The presence of impurities in the industrial-pure mischmetal has no impact on the formation of the 1:13 phase, the presence of the first-order phase-transition property and metamagnetic behavior, and thus maintains the giant magnetocaloric effect of the magnetic refrigeration material. The preparation of La(Fe,Si)13-based magnetic refrigeration material from industrial-pure mischmetal reduces the dependency on high-purity elementary rare earth raw material; lowers the cost for manufacturing the material; and thus plays an important role in development of the magnetic refrigeration application of materials.

Abstract:
A stereo disparity calculating unit calculates the predicted value of the stereo disparity. A line extracting unit performs line extraction in an image. A line classification unit classifies the extracted lines into different line types. A meaningless line eliminating unit eliminates lines not existing in the real world away from the following processing. A stereo disparity correcting unit corrects the predicted value of the disparity based on the line pairs determined by the line pair determining unit. A line pair clustering unit clusters all the line pairs belonging to the same feature as one cluster. A plane combining unit finds out the location relationship in the three-dimensional space among all the planes of each feature extracted by a plane extracting unit, and generates a three-dimensional model describing the overall structure for each feature.
