For accurate flatness measurement of large structures, we propose a method to capture wide and accurate range images by using time-series range images of multiple viewpoint. Given the size of the structure and the measurement accuracy of the sensor, this method calculates the number of divisions and the measurement time. After that, the proposed method made it possible to measure with an accuracy of 0.024 mm to white board. After analyzing the relationship between the accuracy of distance measurementσand the flatness error ΔF, The simulation revealed that ΔF = 11.174σ.
