[0002] With the development of unmanned automatic control technology, the analysis and display of mechanical component situation data has become a hot topic in the research and application fields. Mechanical component situation data includes important data such as the position and posture of space target components at different times. Real-time and intuitive display of mechanical component situation is conducive to helping predict equipment failures, optimizing equipment maintenance plans, and improving equipment operation efficiency and reliability. At present, the conventional mechanical component situation display method uses two-dimensional display, that is, a point or icon is used to simulate the space target in the scene, and the position of the space target is displayed with points or marks, accompanied by text to explain the current situation. However, this type of method or system cannot effectively provide intuitive and interactive display. It cannot meet the needs of analysis and decision-making in complex scenarios. If three-dimensional display technology is used, especially three-dimensional visualization technology based on the Cesium engine, it can intuitively display information such as the position and situation of space target components, thereby improving the effect of situation data display.
