A hub imaging angle monitoring apparatus, comprising an X-axis accelerometer, a Y-axis accelerometer, a Z-axis gyroscope, a micro-processing unit and a power supply unit arranged on a hub, wherein the power supply unit supplies power to the X-axis accelerometer, the Y-axis accelerometer, the Z-axis gyroscope and the micro-processing unit, respectively; and the micro-processing unit is configured to drive the X-axis accelerometer, the Y-axis accelerometer, and the Z-axis gyroscope to monitor movement data of the hub, and to perform a fusion processing on the movement data to determine the imaging angle of the hub.
In some embodiments, the micro-processing unit is configured to perform the fusion processing on the movement data to obtain an attitude angle of the hub, and a hub imaging system is configured to determine the imaging angle of the hub by using the attitude angle as a reference point.
In some embodiments, the micro-processing unit performs the fusion processing on the movement data to filter out the influence of vibration on the hub and obtain the attitude angle of the hub.
In some embodiments, the fusion processing of the movement data performed by the micro-processing unit includes simplified quaternion algorithm plus equalization filtering.
In some embodiments, the fusion of the movement data by the micro-processing unit includes Kalman filtering.
In some embodiments, the power supply unit includes a battery.
In some embodiments, the power supply unit includes a self-energized power generation apparatus.
In some embodiments, the power supply unit includes a solar power generator apparatus.
Compared with the prior art, the hub imaging angle monitoring apparatus according to the present disclosure has the following advantages:
By means of combined application of an X-axis accelerometer, a Y-axis accelerometer and a Z-axis gyroscope and fusion of data by a micro-processing unit, the hub imaging angle monitoring apparatus according to the present disclosure can detect the rotation speed of the hub without relying on external references, can calculate the current attitude of the hub according to the monitoring data, and can monitor the spatial angle of the hub during movement and use this as a reference point to determine the imaging angle of the hub, thereby overcoming image jitter or transient direction changes in image display due to driving bumps, and ensuring the stability of a hub imaging screen.
