【摘要】 采用链码化来描述轨迹曲线,实现了轨迹曲线的链码同一化。介绍了轨迹曲线链码的自动提取与链码的实例化。基于链码及链码匹配的相似度分析,提出了机构反求设计的方法,并开发了原型系统。该方法在轨迹曲线匹配中克服了轨迹曲线类型的局限性,同时能满足轨迹曲线局部匹配的要求。更多还原

【Abstract】 Every single curve can be encoded into a corresponding chain codes, thus any mechanism path curve is figured out under an identical criterion. The very arithmetic was introduced which can extract the chain code of a single path curve automatically and then made it instanced. A mechanism reverse design technique was presented based on chain codes similarity analysis, and followed by a developed prototype system as an example. In practice, this technique conquers the curve type validity limitations in curve matching process, and meets the requirements of partial matching as well as entire matching simultaneously.更多还原
