Algorithm of pulse position identification of complex wave form taken by linear CCD sensor

摘要

According to triangulation principle, optical mechanical and electrical structure of the geometrical parameters of the railway over head contact net auto-measuring equipment based on linear CCD sensors is proposed. For abnormal pulse wave form problem caused by each block of air multi-target, it proposed that the signal, in turn, should be done the following: normalization, a differential, quadratic differential, amplitude separation, location search, and gravitational center computation, which can effectively extract pulse position. Practice has proved that the algorithm recognition is reliable, and the extracted pulse position is used to coordinate calculation, whose precision meets the relevant standards.
