Abstract

The invention relates to a data fusion method and device of double inertial measurement units, computer equipment and a storage medium. The method comprises the following steps: acquiring first data and second data; the first data is data collected by the first inertial measurement unit, and the second data is data collected by the second inertial measurement unit; the X-axis and the Y-axis of the first measuring unit and the X-axis and the Y-axis of the second measuring unit are arranged in opposite directions respectively. And performing data fusion according to the first data and the second data. According to the embodiment of the invention, the data fusion precision of the double inertial measurement units can be effectively improved.

Description

technical field [0001] The present application relates to the field of automatic driving, and in particular, to a data fusion method, device, computer equipment and storage medium of dual inertial measurement units. Background technique [0002] The following statements merely provide background information related to the present application and do not necessarily constitute prior art. [0003] The mass production of autonomous vehicles has very high requirements on the robustness of the sensors on the vehicle. In order to improve the robustness of the sensors, many manufacturers currently have a certain degree of redundancy for various sensors. [0004] Inertial measurement unit (IMU, Inertial Measurement Unit) is one of the very important sensors, its robustness must be guaranteed, and redundancy of the inertial measurement unit will increase the cost. For this, the commonly used solution is Using dual inertial measurement units, the solution is simple and effective, and ...
