Embodiment Construction
[0049] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and which show by way of illustration specific embodiments in which the application may be practiced. In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the figures being described. Because components of an embodiment may be positioned in several different orientations, directional terminology is used for purposes of illustration and is by no means limiting. It is to be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. The following detailed description should therefore not be taken in a limiting sense, and the scope of the application is defined by the appended claims.

This application proposes a reciprocating boundary retrieval method for finding the FPI response center point and its verification method. The method uses the XY slide table data calibration system to detect the FPI response circular chip fixed on the test platform. The XY slide The table calibration system includes a motor, an XY slide table and a spectrum acquisition device, and the spectrum acquisition device runs and scans from the outside of the response range of the FPI response circular chip to the inside of the response range of the FPI response circular chip at the first step value , to obtain the spectral intensity value of each collection point; in response to the change of the spectral intensity value of two adjacent collection points from less than the preset spectral intensity threshold to greater than the preset spectral intensity threshold, determine the first boundary interval. By using the multi-point method for reciprocating boundary retrieval, the round-trip distance of the spectral acquisition equipment can be reduced, thereby greatly shortening the time for finding boundary points, improving the accuracy of the retrieval boundary points, and improving the calibration of the hyperspectral platform or Test speed to achieve rapid production changeover.
Description
technical field [0001] The present application belongs to the technical field of hyperspectral imaging, and in particular relates to a reciprocating boundary retrieval method for finding the FPI response center point and a verification method thereof. Background technique [0002] The FPI response circular chip used in the field of hyperspectral images usually needs to calibrate its parameters such as transmittance and reflectance. To perform spectral analysis on each point on the chip, it is necessary to find a reference point for data testing and calibration. [0003] Prior to this, the judgment of the FPI boundary point and center point was estimated by the inspector by visual inspection, and the coordinate value of the XY slide table was adjusted step by step. By observing the spectrum curve graph of the spectrum acquisition device at each coordinate point, it was judged whether to enter the FPI response In the circular chip, the coordinate value of the boundary point is...
