Column Alignment Measurement System (Top-Down Installation Method)

This system automatically measures the alignment of a support column in top-down construction using a camera-equipped vertical surveying device. By placing a the device at the top and a target at the bottom, it can accurately measure the installation accuracy of the support column. Furthermore, based on the position of the object captured by the camera and the value from the built-in inclinometer of the vertical level, it calculates the deviation of the support column from vertical.
