As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

Besides, the experimental group also shows a significant improvement in the spatial perception, spatial orientation, spatial relation and spatial reasoning. According to the logs recorded by Happy Cuber within the three weeks learning, the progress of the students in accuracy and problem solving time is obvious. The stage of Happy Cuber in developing part is harder than the folding part for students, whether in folding or developing part, the cross-shaped net is the highest accuracy and shortest response in all cubic nets.

从教材操作纪录内容的变化来看，学生在游戏中的答题正确度与解题时间随著教材使用次数渐次提升，统计分析后发现，立方体拆解题型难度要比展开图摺合题型高，十字型展开图不论是摺合或拆解上，在正方体11个展开图中都是费时最短且正确率最高的类型。

However, this examination never has a standard answer; in other words, it is a test that challenges examinees' capability and endurance, and moreover, its judgment is not made at present or on the site but may show up behind the curtain of time or in the far future.

有许许多多应试者怀着朴素的理想和最初的冲动进入考场，希翼能够尽快找到解题的方式，获取成功的答案，但是，这种考试是一种没有标准答案的考试，或者说，对于所有的受试者，它是一种不仅检测能力而且检测耐力的考试，它的评判者甚至不在考试的当下和现场，而在时间帷幕的后面或遥远的将来。
