When the parameter matching of the wheel location is improper, namely, the matching between the wheel toe-in and the wheel camber angle is ill-suited, abrasion of the two wheels of the same steering axle is inside or outside simultaneously, because of wheels sideslip. However, when double-front-axle steering system failure take place, abrasion of the two wheels of the same steering axle is in the same side, and that, tyre abrasion direction of front and back steering axles is rightabout. That is to say, if tyre abrasion of front steering axle lie in the left side, tyre abrasion of back steering axle lie in the right side to a certainty, which is the rule of tyre abrasion of double-front-axle steering automobile.

当定位参数匹配不当时，同一转向轴上左右车轮的磨损部位都在内侧或外侧，原因是左右车轮在滚动的同时还要产生相向或反向侧滑；而双前轴转向汽车前、后转向轴引导汽车转向方向不一致时，同一转向轴左、右车轮的磨损部位都在同一侧，而且前、后转向轴上的车轮偏磨损方向正好相反，即如果前转向轴左、右车轮磨损部位在左侧或右侧，那么后转向轴左、右车轮磨损部位就在右侧或左侧，这是双前轴转向汽车特有的轮胎磨损规律。

The robustness is obtained thanks to the fact that some local mismatches in the approach are generally impossible to change the global correct matching trend The method can not only be used for sectional images matching in medical field as it did in the thesis, but can also be used in other fields, such as stereo vision [2] Distance transformation plays quite an important role in object thinning and skeletonization in image processing.

The existing image matching methods work well in open areas with relatively smooth terrain. However, they still meet many problems in the case of larger scale images of nature, especially in the dense city centers, forestry areas and the textureless regions such as water bodies. The reliability of image matching is still a big issue in these cases. For example, the corners of buildings and some object boundary points sometimes cannot be matched successfully, and there are many blunders in the automatically derived digital surface models that need to be manually removed, which leads to the decrease of the automaticity in digital photogrammetry.

现有大多数立体影像匹配方法对于地形平滑的开阔地带具有较高的可靠性，然而，面对从千变万化的自然界所摄取的影像，现有的匹配方法仍然存在许多问题，尤其是在植被茂密、建筑物密集和水域等区域，影像匹配的可靠性还不高，一些建筑物的角点和地物的主要边界点还不能正确地匹配出来，自动生成的数字表面模型中存在着许多异常值，需要进行大量的人工编辑处理，这在很大程度上制约了数字摄影测量自动化水平的提高。

In degraded PSM matching classification, errors modification method of degraded PSM is presented and the matching tensor of every canonical scattering centers is given. In Chapter 4, the theory of wideband millimeter-wave radar target identification is introduced. It is indicated that, for HR radar target identification, description of temoral relations among features and pattern recogntion adaptive to variation of target angles are of key importance. A rule-based pattern recogniton method of sequential reasoning is proposed, which uses a series of rules to describe relations of features variation caused by target angles variation and has the advantages of adaption to unrandom variation and false probability control in classification over traditional statistical pattern recognitiop method. Feature extraction is crucial step in target identification. In range profiles identification application, features are extracted by means of range domain pre-processing algorithm, spacial and amplitude visual computation directly from range profiles and transform algorithm based on range profiles. Visual or transformed features are either sufficiently convinced or necessarily convinced and both of them are effective and robust to range profiles identification.
