Image quality assessment is meaningful for the research of imaging performance of laser active imaging system.The quality of laser active illumination image is quantiatively from three aspects of the image，including noise,gray leve1and texture.And combine calculations of single factor evaluation parameter and weighting coefficient giving by the experts by the meanings of Choquet fuzzy integral,setting up the comprehensive assessment model of image performance of laser active imaging system.In this way,we can get the assessment system interface by programming.
