Document Type and Number:
WIPO Patent Application WO/2011/090177
Kind Code:
A1
Abstract:
Disclosed in an inclination detection device (1) provided with a first inclination sensor (2) which detects an inclination with respect to the direction of gravitational force with a high degree of accuracy and a second inclination sensor (3) which detects the inclination with respect to the direction of gravitational force with a lower degree of accuracy than said first inclination sensor over a wider area than said first inclination sensor, wherein said first inclination sensor and said second inclination sensor are fixed relatively to each other and the inclination is detected by said second inclination sensor with reference to a reference position and a detection direction detected by said first inclination sensor.
