To reduce the influence of the temperature variation on the measurement result of the car body-in-white laser visual measurement system,a temperature error compensation model based on coordinate error is established with a sphere target which is mounted near the base frame of the industrial robot.

This dissertation applies the kinematic calibration principle and computer vision technique to improve the X-Y table accuracy via geometrical parameters identification and errors compensation.

This paper deduced precisely the errors formula of AC synchronous sampling to voltage,solved the lower precision problem caused by changing-frequency signal,and put forward errors compensation.

This paper introduces the construction and application in manufacturing wheel cutter of the single chip computer controlled error compensating system ,discusses emphatically collection and processing beforehand of error data as well as analysis of compensating precision .

After analysing the error of pitch, this paper put forward a method of error compensating without the error compensating mechanism in a numerical controlled lathe.
