Abstract

A comprehensive comparative study focusing on central projection and parallel projection is conducted in this paper. The two projection methods are systematically analysed from multiple perspectives including their physical definitions, fundamental principles, mathematical theorems, geometric properties, algorithmic implementations, and practical applications. The differences and connections between the two projections are elucidated in detail. Their advantages and disadvantages across various disciplines are also explored, and the study of an application example is given. It is demonstrated that central projection, which simulates human visual perception, provides more realistic scene perception and is suitable for visual arts production field, but non-linear transformations and more complex computation are involved, leading to an inaccurate geometric measurement. In contrast, parallel projection preserves geometric proportions through linear transformations with simpler computations, but lacks spatial depth perception, rendering it ideal for precision-dependent fields such as measurement and manufacturing. Finally, the application of integration on central projection and parallel projection methods and their development in the future are explored. This study provides valuable references and insights for related research fields.
