| Summary: | 碩士 === 大葉大學 === 電機工程學系碩士班 === 93 === The long wavelength of 8~14μm has a sensitive thermal response which can normally be utilized on object heat detection with very dark and invisible background. It is difficult to receive the external interference in such circumstance. Most of Infrared image application can be applied by these technology to extend its object detection ability and noninvasive on any target recognition, not only for detection but also more secure in industrial and military application.
This thesis is mainly made in order to correct the body of infrared ray thermal camera by integrated Limited Company of the Han Tang. In order to match the constant temperature and suitable humidity adjustment, the system temperature measurement has to be met that condition for correct temperature inspection and adjustment.
After thermal image captured from Infrared camera, the nonlinear aberration incurred from the lens set and focal plane array will generate the non-uniform problem during the measurement. In other words, two-dimensional temperature measurement involved in the phenomenon of the appearance of numerical inconsistent must be treated with uniform adjustment to meet accuracy requirement and result with optimal linear property. In this paper, several algorithms will be approached to resolve the non-linear effect and obtain the optimal calculation resulted from this research. Particularly, the dead pixels removal, optimal contrast and brightness are also considered in this algorithm research for the optimal implementation.
