Abstract: A method for determining the bend of a tubular structure, including determining the inclination of first and second rigid objects fixed in distinct locations along the tubular structure. The method includes supplying accelerometers (A1, . . . AN) rigidly linked by the object to measure an acceleration in at least one direction of measurement (vj), the respective directions of measurement of at least two of said accelerometers being non-collinear. The measurement, by the accelerometers, of the components of the Earth's gravitational field along said directions of measurement, the measurement providing, for each of said directions, a measurement value, denoted mj for a measurement direction of index i. The method includes solving a defined matrix equation to determine the inclination Φ of the object relative to the reference frame of reference.

Abstract translation: 一种用于确定管状结构的弯曲的方法，包括确定沿着管状结构固定在不同位置的第一和第二刚性物体的倾斜度。 该方法包括提供由对象刚性连接的加速度计（A1，... AN），以测量至少一个测量方向（vj）的加速度，至少两个所述加速度计的各个测量方向是非共线的。 通过加速度计测量沿着测量方向的地球重力分量的分量，测量为每个所述方向提供测量值，对于索引i的测量方向为mj。 该方法包括解决定义的矩阵方程以确定对象相对于参考参考系的倾斜度Φ。
