Frame structure was needed to provided a stable basic to the aerial remote camera,and it could be influnced directly by the links of assemble.In order to get a high accuracy and good stablity frame structure,assembly stress shoule be reduced.The principle of mechinery connected method and the cementecl were introduced,on the basic of the structure of a camera and the request of assemble were explaned shortly.Two methods were adopted,and the results of them were analyzed.It showed that the assembly distort of mechinery connected method is about 0.03mm～0.04mm,while the assembly distort of cementecl could be controled less than 0.01mm.Both of them could be used in assemble,but cementecl may reduce assembly stress and improve the accuracy and the stablity of frame better.
