镜像投影是为了补充直接正投影法对某些工程构造表达的不足而引入的．对工程制图中空间物体生成镜像投影的形成过程进行了较为详细的论述，并根据镜像投影的形成过程给出了数学模型，使用这一数学模型可以方便地利用计算机来实现镜像投影的自动生成．这一问题的研究对计算机制图是一个有益的补充．
The mirror projection is introduced to supplement the direct projection method for the lack of expression of certain engineering constructs. The formation process of the mirror image projection of space object in engineering drawing is discussed in detail, and the mathematical model is given according to the forming process of the image projection. Using this mathematical model, the computer image mirror projection can be automatically generated. The study of this issue is a useful supplement to computer graphics.
