PROBLEM TO BE SOLVED: To provide an inclination detection system and an inclination detection method capable of easily detect an inclination angle of a target with high accuracy.SOLUTION: The inclination detection system includes: a measurement apparatus 1 having a ranging function and a line laser irradiation unit 29 disposed to be horizontally rotatable and to irradiate a target with a vertical line laser beam 5; and a light-receiving apparatus 2 having at least two light-receiving units 6, 7 disposed at a given interval, a retroreflective target 4, and a computing unit 10. The line laser irradiation unit 29 is rotated to scan each light-receiving unit 6, 7 with the line laser beam 5, and the computing unit detects an inclination angle of the light-receiving apparatus 2 on the basis of a shift in a light-receiving time between the light-receiving units 6, 7 and on the ranging results on the target 4 by the measurement apparatus 1.SELECTED DRAWING: Figure 1 |
