To measure the location parameters for projectile burst on a proximity fuze in high altitude,an intersection imaging method by using two planar array cameras and taking a simulant object as reference was put forward to calculate three coordinate parameters of projectile burst location.According to the request of proximity fuze test,the principle and method of camera intersection imaging were analyzed,and the measuring model of projectile burst location was set up.The relations of space geometric locations of the camera layouts,the technology of image processing and the sizes of objects were analyzed,the spatial three coordination of projectile burst location were calculated,and the parameter modification method was studied.A differential method was employed in analyzing the location errors,and results show that the differential coordinate errors are less than 40mm.Experiments and image processing were performed,which shows that the planar array camera intersection imaging can obtain the spatial three coordination of projectile burst.Furthermore,the data by proposed method are compared with that of the four screen across system,and their average error is 0.158min the high and low directions and 0.114min right and left directions.
