Problems solved by technology

[0004] However, if the terminal is not fixed in the vehicle, that is, there is relative movement or rotation between the terminal and the vehicle, the IMU data measured by the IMU of the terminal cannot accurately represent the IMU data of the vehicle, which affects the IMU data based on the vehicle. Detection accuracy for detecting the pose of the vehicle

Abstract

The embodiment of the invention relates to a terminal state detection method and device, a terminal and a storage medium. The method comprises the steps of acquiring target IMU data of a target terminal; detecting whether the target IMU data meets a preset state judgment condition or not, wherein the state judgment condition is determined according to characteristics of IMU data when the terminalis fixedly arranged in the vehicle; and if the target IMU data do not meet the state judgment condition, determining that the target terminal is not fixedly arranged in the vehicle. By adopting the method, whether the terminal is fixedly arranged in the vehicle or not can be accurately detected.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of the Internet, and in particular, to a terminal state detection method, device, terminal and storage medium. Background technique [0002] An inertial measurement unit (Inertial Measurement Unit, IMU) is a device that measures the angular velocity and acceleration of an object. Generally, an IMU includes three single-axis accelerometers and three single-axis gyroscopes, which are used to measure the acceleration value and angular velocity value of an object in three-dimensional space, that is, IMU data. [0003] Currently, IMU data are widely used in many fields. Taking driving safety as an example, the vehicle can be a vehicle. For example, the posture of the vehicle is detected through the IMU data of the vehicle, so as to detect whether the vehicle has dangerous driving behaviors such as rapid acceleration, sharp turn, sudden lane change, and rapid deceleration. Since the IM...
