A laser detection method based on MNF for deformation of air conditioning motor starting control equipment is proposed.Firstly,laser scanning technology is used to obtain the specific deformation position of air conditioning motor starting control equipment.The improved minimum noise separation transform(MNF)method is used to estimate the noise information and reduce the dimension by differential calculation.Then,the deformation degree of the air conditioning motor starting control equipment in the low dimensional noise image is determined by using the laser detection technology.Finally,the simulation results show that the proposed method can effectively reduce the false alarm rate and miss detection rate.
