Abstract

The invention discloses a detector array target data processing method. The method comprises the steps of determining a corresponding relation between an interpolation multiplying power and a pixel point decimal part gray value; determining the relation between the interpolation multiplying power and the weight coefficient matrix J and the relation between the interpolation multiplying power and the weight coefficient matrix L according to the corresponding relation between the interpolation multiplying power and the gray value of the decimal part of the pixel point, the formula J = [A1A2... AK] and the formula L = JT = [A1A2... AK] T; obtaining a light spot image matrix collected by a detector array target and a set interpolation multiplying power value; selecting a weight coefficient Jpand a weight coefficient Lp corresponding to the interpolation multiplying power according to the corresponding relation between the interpolation multiplying power value and the decimal part gray value of the pixel point; and performing interpolation processing on the gray value G (i + u, j + v) of each pixel point in the light spot image matrix to obtain the gray value G '(i + u, j + v) after the interpolation processing. The detector array target data processing method provided by the invention has the characteristics of high image processing efficiency and high image processing precision.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a detector array target data processing method. Background technique [0002] Accurate measurement of spatio-temporal intensity distribution of laser far-field spot is an effective means to directly obtain important parameters such as laser spot to beam quality, target energy and center of mass drift. It is useful for analyzing the transmission effect of strong laser in the atmosphere and evaluating the beam control ability of strong laser system , aiming ability, etc. are of great significance. [0003] At present, the methods of measuring far-field spot parameters at home and abroad are mainly array detection method and camera method. The camera method adopts non-contact measurement, which has the advantages of simple structure and easy to obtain high-resolution spot images, but it is difficult to achieve quantitative measurement of the spatial distribution of the spo...
