Abstract:
(EN) [Problem] To easily verify and reset an integrated attitude angle based on the output of an inertial sensor. [Solution] An attitude angle calculation device 10 is provided with an integrated attitude angle calculation unit 41, an inverse value calculation unit 421, a reference value calculation unit 422, and a determination unit 43. The integrated attitude angle calculation unit 41 calculates an integrated attitude angle using a position measurement signal and the output of an inertial sensor. Using the integrated attitude angle, the inverse value calculation unit 421 inverse-calculates a physical quantity utilized to calculate an attitude angle using the position measurement signal. From an observed value of the position measurement signal, the reference value calculation unit 422 calculates a reference physical quantity corresponding to the inverse-calculated physical quantity. The determination unit 43 determines resetting of integrated attitude angle calculation processing using the inverse-calculated physical quantity and the reference physical quantity.
(FR) La présente invention vise à vérifier et à réinitialiser facilement un angle d'assiette intégré sur la base de la sortie d'un capteur inertiel. À cet effet, l'invention concerne un dispositif de calcul d'angle d'assiette 10 qui comprend une unité de calcul d'angle d'assiette intégré 41, une unité de calcul de valeur inverse 421, une unité de calcul de valeur de référence 422, et une unité de détermination 43. L'unité de calcul d'angle d'assiette intégré 41 calcule un angle d'assiette intégré à l'aide d'un signal de mesure de position et de la sortie d'un capteur inertiel. A l'aide de l'angle d'assiette intégré, l'unité de calcul de valeur inverse 421 calcule l'inverse d'une quantité physique utilisée pour calculer un angle d'assiette à l'aide du signal de mesure de position. A partir d'une valeur observée du signal de mesure de position, l'unité de calcul de valeur de référence 422 calcule une quantité physique de référence correspondant à la quantité physique inverse calculée. L'unité de détermination 43 détermine la réinitialisation du traitement de calcul d'angle d'assiette intégré à l'aide de la quantité physique inverse calculée et de la quantité physique de référence.
