| Popis: | To improve the identification ability and accuracy of multi-target and multi-screen intersection measurement systems, this paper proposes a new identification method. This method uses the multi-screen spatio-temporal information constraint theory for multi-screen intersection measurement systems, and develops both recognition model and signal processing method using wavelet identification on a single detection screen. According to target signal identification algorithm and space geometric structure relationship, the spatio-temporal characteristics are analyzed when targets pass six photoelectric detection screens. Furthermore, the multi-target recognition and matching calculation model is structured based on the spatio-temporal information constraints of this multi-screen intersection measurement system. When the targets pass the screens, temporal and spatial information constraints affect both adjacent photoelectric detection screens. If the targets reach the same screen at the same time, they will not be detected at the same time. The proposed method solves the identification and matching problem of multi-screen intersection measurement systems. |
