Abstract

The invention provides a calibration method of a multi-spectrum collecting system. The calibration method includes the following steps: collecting scene information under a standard light source through the double-path multi-spectrum collecting system to obtain two paths of multi-spectrum images, carrying out spectrum calibration on spectrums at sampled points according to spectrum information of the sampled points of one path of multi-spectrum images, the spectrum characteristic of the standard light source and the light path characteristic of the multi-spectrum collecting system, providing two scanning videos in different scanning directions, carrying out the demonstration through a calibration video demonstration device, respectively shooting the two scanning videos during the demonstration, and obtaining matching points of the sampled points according to the two shot scanning videos to complete space position calibration of the sampled points. According to the calibration method, spectrum calibration can be accurately carried out on the double-path multi-spectrum collecting system, alignment matching can be accurately carried out on the space positions of the two paths of collected images, and therefore the double-path multi-spectrum collecting system can effectively collect spectrum images. The invention further provides a calibration system of the multi-spectrum collecting system.
