Optical measurement occupies an important position in the missile and spacevehicle exterior trajectory measurement, the new generation optical measurementequipment generally used digital recording mode,the current high-speed digitalimage recording system mainly includes three kinds of modes: internal storagerecords, FLASH records, high-speed disk array recording Due to the design,All thethree models record and store the image and data separately, thencombine them intothe images including time,angle,and other date according to a certain logic,whenerrors occur in this combination,it will cause additional information of a frame ofthe images is not the real recording information, this weill creste deviation to thedata processing afterward.In order to ensure the reliability and authenticity of theusage of the high-speed digital measured images. Based on the range of ahigh-speed TV measurement system at the range,. The artiale carried out theresearch of synchronization precision detection technology of high-speed digitalimage recording.The article first,through analysis the synchronization precision feasibility of thehigh-speed TV measurement system, put forward the method for determining thehigh-speed digital recording system’s synchronization precision by detecting theexact time of the exposure; then,studied the detection method of displaying theadjustable lighting time and reference information through lattice,ande analyzed thelattice shooting method,as well as the after calculation of the synchronizationprecision’s;at last,it designed a set of synchronization precision detection system,italso had error analyses and tests to the system..Through application in high-speed TV measurement system and other opticalmeasurement system at the range, the design can detect the synchronizationprecision of the system, thus,it can check the validity of the data record ofhigh-speed digital image recording system.This fully shows the synchronizationprecision detection system mentioned in this paper is practicalue and significance,it will make a good contribution to the optical measurement system’s digitalizationand informatization in the space lauch site,as well as the weapon test range’s construction. |
