As existing angle measuring instruments for building cannot fulfill the requirements in practice due to their low accuracy and instability,a novel design solution for angle measuring instrument is proposed,which applies the digital angle sensor,SCA61T.By analyzing the cause of system perturbation and mechanical error in angle measuring,the method is designed by integrating the average median filtering,the calibration of standard point and the linear fitting to realize the compensation of the error.The results of simulation and practical application illustrate that the improved angle measuring instrument designed in this paper performs well in terms of the accuracy of angle measuring and working stability,and the accuracy of angle measuring and display research to 0.05 and 0.01,respectively.The approach greatly reduces the angle measuring error and meets the requirements of practices.
