本文提出了一種在復雜場景中實時檢測、識別多個目標物體的方法。利用由矩陣碼（matrix code）構成的 2D 矩陣來識別復雜場景中多個目標物。算法不僅能適應目標物體在旋轉、縮放、平移變換下的不變性識別，而且能適應仿射及射影變換下的不變性識別。試驗結果證明所提供的算法在識別和監視系統中有很好的魯棒性和實時性。

Abstract: An method for real-time detection and recognition of multi-targets in complex scenes is presented.This method utilizes 2D matrix markers, being composed of matrix code ,which can identify a large number of objects.The algorithm can adapt to object recognition，invariant not only under rotation、scaling、 translation , but
under affine and projective transformation. Experimental results are given to demonstrate the robust adaptation and real-time of the algorithm in recognition and surveillance system.
Key words: matrix code; object recognition; corner detection; perspective transformation; image matching.
