Discrimination filtering equipment, discrimination method of the object, and a method of designing a filter of discrimination filtering equipment

摘要

Discrimination filtering device (10), a filter with a transmission band different filter (20.1) and (20.2), a detector (30), the arithmetic unit (40), a result output unit (50) I include a. Detector (30), and filter (20.1) through a filter (20.2) is detected by (30) detector, the electromagnetic wave from the object to be the identification object. Here, the transmission band filter and a filter (20.1) and (20.2) are designed to be appropriate to determine the object. Computing unit (40), assigns the output detection section (30) to the discriminant function is determined based on the teaching spectrum is obtained in advance and the transmission band filter and filter (20.1) and (20.2), assignment estimating the group object belongs based on the results.
