Abstract

Embodiments of the present application provide a method, apparatus, and medium for data transmission. In some exemplary embodiments of the present application, by setting two message queues, the MCU reads the pose data generated by the IMU from the first message queue and reflects the data storage state of the second message queue through the state of the data in the first message queue; and whenthe state of the data of the first message queue reflects that the data of the second message queue is not full. The MCU reads the attitude data generated by the IMU and writes the attitude data intothe second message queue for the host computer to read the attitude data from the second message queue. The host computer reads the IMU data in real time and accurately to judge the attitude of the head-worn equipment, so as to improve the accuracy and effectiveness of the host computer in acquiring the IMU data. The MCU reads the attitude data generated by the IMU and writes the attitude data into the second message queue.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data transmission method, device and medium. Background technique [0002] IMU (Inertial Measurement Unit) is a device that measures the three-axis attitude angle (or angular rate) and acceleration of an object. Generally, an inertial measurement unit includes three single-axis accelerometers and three single-axis gyroscopes. The accelerometer detects the acceleration signal of the object in the three-axis independent of the carrier coordinate system, and the gyroscope detects the relative to the navigation coordinate system of the carrier. The angular velocity signal of the object is measured, the angular velocity and acceleration of the object in three-dimensional space are measured, and the attitude of the object is calculated based on this solution. [0003] In computer science, a message queue is a software engineering component used for inter-proces...
