Title:
INERTIAL MEASUREMENT APPARATUS FOR THREE-AXIS MECHANICAL GIMBAL
Document Type and Number:
WIPO Patent Application WO/2024/022024
Kind Code:
A1
Abstract:
An inertial measurement apparatus for a three-axis mechanical gimbal, comprising a mounting plate (100), an inertial measurement module (200), a control module (300), and a heating module (400). The inertial measurement module (200), the control module (300), and the heating module (400) are all arranged on the mounting plate (100). The control module (300) is connected to the heating module (400). The control module (300) is configured to control the heating module (400) to work. The inertial measurement module (200) is provided with a temperature measurement unit (210). The temperature measurement unit (210) is communicationally connected to the control module (300). When the temperature of the inertial measurement module (200) is lower than a target temperature value, the control module (300) controls the heating module (400) to be turned on, so that the inertial measurement module (200) is heated. When the temperature of the inertial measurement module (200) is higher than the target temperature value, the control module (300) controls the heating module (400) to be turned off, so that the inertial measurement module (200) dissipates heat and cools. Therefore, the inertial measurement module (200) works in a relatively stable temperature state, thereby implementing the constant temperature control function of the inertial measurement module (200), preventing a zero-offset change of the inertial measurement module (200) due to the influence of the temperature, and ensuring the photographing effect of a three-axis mechanical gimbal camera.
