This invention discloses a dual-stream point cloud compression method and system based on semantic scene graphs, relating to the field of point cloud compression. It constructs a point cloud compression network comprising an encoder network and a decoder network: In the encoder network, semantic labels are mapped onto the input point cloud, and scene graphs and octree representations are constructed respectively. Semantic modulation parameters are generated based on the scene graph and encoded to obtain a semantic bitstream.

This invention discloses a Z-axis micromechanical accelerometer and its control method, belonging to the field of acceleration measurement technology. An asymmetric seesaw sensing structure is constructed using mass blocks and a torsional elastic beam. Two symmetrical multifunctional capacitors are formed by designing electrodes below the two mass blocks. The torsion generated by the seesaw structure under Z-axis acceleration can be detected by the change in the differential capacitance of the capacitors, where the capacitors serve as the detection mechanism. Based on the detected change in torsion angle and the PID controller, a PWM voltage for force balance control can be calculated and applied to the symmetrical capacitors via a push-pull method, together with a DC tuned voltage.

The PWM voltage reflects the magnitude of the external acceleration.
