Method for measuring curved surface temperature through infrared microscope

Abstract

The invention discloses a method for measuring curved surface temperature through an infrared microscope. The method comprises steps of (1) putting areas to be measured of a piece to be measured on an observation desk under a lens of the infrared microscope; (2) moving the lens of the infrared microscope to enable the highest position or the lowest position of the piece to be measured to be positioned at focusing positions of the lens of the infrared microscope; (3) acquiring infrared images of the piece to be measured at the focusing positions through an infrared charge coupled device (CCD) in an infrared microscope system; (4) collecting infrared images at different focus positions by setting step lengths according to depths of field of the lens of the infrared microscope; (5) fusing the infrared images at different focus positions into an infrared image where all the positions are in clear focusing state through a multi-focus image fusion system; (6) acquiring temperature information corresponding to the infrared image according to the fused infrared image to achieve precise measurement of the curved surface temperature. The method is applicable to any curved surfaces with projections in the vertical direction non-overlapped or nearly non-overlapped.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for measuring the temperature of a curved surface using an infrared microscope. Background technique [0002] The infrared microscope integrates the microscopic magnification function of the visible light microscope and the temperature measurement function of the infrared thermal imager. It is mainly used for the measurement of the temperature of a small area and the detection of infrared characteristics. , scientific research and other aspects have a wide range of applications. [0003] At present, an infrared microscope collects an infrared image of a focal plane, and uses the image information to obtain temperature information. The clarity of the infrared image affects the accuracy of the temperature. When the surface fluctuation of the measured object is within the depth of field of the microscope lens, clear infrared images of the object can be obtained at all posit...
