Zusammenfassung:	A method for detecting pixel defect points in uncooled infrared core image includes collecting N frame core images through image acquisition card, reading N frame core images, analyzing gray value ofN frame core images to obtain gray information of each frame core image; averaging gray values of pixels corresponding to N frames of movement images to obtain an averaged image; calculating a mediandifference MedDif [x] [y] of pixel coordinates (x, y) in the average image and a judgment threshold BP of the current state of the movement, if MedDif [x] [y] > BP, the pixel is judged to be a brightdefect point, if MedDif [x] [y]
