PDAF-Based Two-Target Data Association Algorithm with Source Code

In this document, the author highlights the practicality of the source code for the PDAF-based two-target data association algorithm. However, we can further explore the background and applications of this algorithm. PDAF, an acronym for Probabilistic Data Association Filter, is a filtering algorithm commonly used in target tracking. It is applicable not only to single-target tracking but also to multi-target tracking scenarios, as it can process multiple observation data simultaneously and associate them effectively. Additionally, PDAF has several variants, such as CPDAF (Cheap PDAF) and JPDAF (Joint PDAF), each tailored for specific use cases. The provided source code for the two-target data association algorithm based on PDAF can serve not only as a tool for target tracking but also as an excellent introductory resource for learning PDAF algorithms. By studying the code implementation, developers can gain deeper insights into how PDAF algorithms are structured and optimized, including key functions like probability calculation, data association logic, and state update mechanisms. This understanding can inspire new ideas and approaches for personal research and practical work in target tracking systems.
