In this research project, effective environment for drawing understanding system realization, ie. drawing understanding system compiler, has been successfully developed. The following concrete results have been obtained.(1) Development multi-purpose drawing understanding system (a drawing compiler I) based on state-transition description of recognition rules:A state-transition type drawing compiler, where recognition level of objects in a drawing corresponds to a 'state' and bottom up and top down recognition rules correspond to 'transitions from state to another states' has been proposed and implemented by about a 6,500 lines Program of C and Prolog languages. Experiments for maps, hand-written drawings and relatively simple engineering drawings revealed the effectiveness of this system.(2) Development of a general purposed drawing complier II base on object-oriented model description of target drawings:Another type of drawing complier, where TMS and object-oriented model description of a target drawing are introduced, has been proposed and implemented by a about 5,000 line Prolog and 7,000 lines C program. Experiments for engineering drawings, layout diagrams revealed generality and effectiveness of the method.(3) Two suporting system also have successfully developed; one is original spatial data management structures and the other is a recognition rule learning system based on given positive and negative examples.

在这个研究项目中，有效的绘图理解系统实现环境，即。绘图理解系统编译器，已开发成功。取得了以下具体成果。 (1)基于识别规则的状态转移描述的多用途绘图理解系统(绘图编译器I)的开发：状态转移型绘图编译器，其中绘图中对象的识别级别对应于“状态”，自下而上和自上而下的识别规则对应于“从状态到另一个状态的转换”，已经由大约6,500行C和Prolog语言程序提出并实现。对地图、手写图和相对简单的工程图的实验验证了该系统的有效性。(2)基于目标图的面向对象模型描述的通用绘图编译器II的开发：另一种绘图编译器，其中TMS介绍了目标绘图的面向对象模型描述，提出并通过约5000行Prolog和7000行C程序实现。通过工程图、平面布置图的实验验证了该方法的通用性和有效性。(3)两个支撑系统也研制成功;一种是原始的空间数据管理结构，另一种是基于给定的正反例的识别规则学习系统。
