The invention discloses a method used for Bayer Data interpolation which includes steps as follows: calculating gradient value on three directions through R or B component contained by a present pixel point, selecting a pixel point containing G component on one side with minitype edge difference value of two edge direction sides for restoring G component of the present pixel point. The method solves problem of rough edge transition caused by bilinear interpolation. The method can restore lack B or R component in the present pixel point for avoiding color distortion of gradient color bilinear interpolation caused by mistake judgement.

The invention discloses a switch cabinet fault diagnosis method based on an on-line indirect temperature measurement mode. Judgment of fault states of the switch cabinet is conducted through temperature real-time monitoring carried out on an indirect temperature measurement point and an environmental temperature measurement point used for installation of temperature measurement sensors on the outside of the switch cabinet. According to the method, physical modeling and measurement point selection are firstly carried out; a temperature theta[2](t) of the indirect temperature measurement point and the temperature theta[0](t) of the environmental temperature measurement point are measured in real time; then a temperature theta[1](t) of a lumped heat source center inside the switch cabinet and a load ideal temperature theta[1](t)[LX] of the lumped heat source center and /or a determined load ideal temperature theta[2](t)[LX] of the indirect temperature measurement point are calculated; the measured temperature and the temperature obtained through calculating are compared with thresholds in a fault judgment standard to finally give a fault state diagnosis. The indirect temperature measurement method is employed in the invention to substitute for a complex and expensive direct temperature measurement mode. The operation is simple and the cost is reduced.
