Background technology

When thermography analysis, for acquisition is to the analysis data of subject thermal imagery and diagnostic result, at present, need manually to arrange analyzed area, analytical model, diagnostic rule to thermal-image data frame, the combination in one or more regions such as analyzed area such as point, line, surface, the position of corresponding subject thermal imagery Water demand; Analytical model, the analytical calculation rule that such as analyzed area is corresponding, as calculated maximum temperature, medial temperature, minimum temperature, degree etc., and the calculated relationship that also can comprise between analyzed area is as the temperature difference etc.; Diagnostic rule, such as, with analyzed area and analytical model, corresponding comparison and threshold value etc.

The setting of analyzed area, analytical model, diagnostic rule, when by manually completing, operates very loaded down with trivial details; Current operation steps is generally the composition data in first selection analysis region, such as point, line, surface; Then, analyzed area is arranged in infrared thermal imagery, and adjusts the location parameter that analyzed area is arranged in infrared thermal imagery; During as arranged multiple analyzed area, by setting operation repeatedly.Then, according to the numbering of analyzed area, input analytical model; Then according to analytical model, carry out layout diagnostic rule.
