Abstract��The contrast test of the manual measurement and automatic measurement were arranged��the differences between the two methods were analyzed. The test results show that the differences between the manual measurement and automatic measurement are existent objectly��and the fault location is the decisive factor in determining the difference between the two methods.When the high demand of elongation after fracture is needed��manual measurement should be used in order to get the real value.
