Rapid Prototyping by Interaction with Real Objects

对于CAD/CAM/CAE的实际应用来说，处理海量信息输入需求是一个难题。特别是目前的二维输入方法对于输入用于构造具有美学特征的三维形状信息的必要信息来说是不令人满意的。为了解决这个问题，一种新的输入法是利用现有的对象或原型产品开发的.三维界面：通过使用三维指向设备直接操纵计算机模型已经开发出来。该方法可以有效地用于美学形态的精细化加工.模型输入法：研究了通过测量真实的物体获取三维形状信息，并在计算机中对测量的形状进行重建，再通过人机交互进行进一步的细化.快速原型信息生成：已经开发了自动数据生成方法，用于通过使用快速原型设备（例如激光光刻机）来创建对象。通过分析层方向和激光扫描方式，提出了避免成形误差的新算法，提出了通过与真实的物体交互快速生成高质量计算机内部图形的方法，并通过实验系统验证了其有效性。

For CAD/CAM/CAE practical applications, one of the difficult problem is to deal with huge amount of information input requirement. Particularly today's two dimensional input method is not satisfactory for inputting necessary information for constructing three dimensional shape information with aeshetic features. To solve this difficulty, a new input method is developed by use of existing objects or prototype products.1. Three Dimensional Interface :Direct manipulation of computer models by use of three dimensional pointing devices has been developed. This method can be used effectively for fine elaboration of aesthetic shapes.2. Model Input Methid :A method has been investigated for capturing three dimensional shape information by mesuring real objects, and for reconstruction of measured shapes in computer, and further elaboration with human interaction.3. Rapid Prototyping Information Generation :Automatic data generation methods have been developed for creating objects by use of rapid prototyping devices, such as laser lithographic machines. New algorithms have been considered for avoiding shaping errors by analzing layr directions and laser scanning modes.In summary, methods for rapidly crating high-quality computer internal by interaction with real objects have been developed, and their effectiveness have been verified by an experimental system.
