The invention discloses a human body use state dynamic evaluation method based on artificial intelligence. The method comprises the steps that state information used for reflecting the overall human body use state is acquired; analyzing the state information based on an artificial intelligence model to judge whether the human body use state is suitable for continuing or not; outputting a judgment conclusion according to an analysis result, wherein the judgment conclusion is used for indicating whether the human body use state is allowed to continue; in the continuous use process of the human body, the steps are periodically repeated to keep the consistency and stability of judgment. The invention further discloses a human body use state dynamic evaluation system based on artificial intelligence. By using the method or the system, the overall state in the continuous use process of the human body can be dynamically tracked and evaluated, the long-term consistency and stability of judgment are ensured, and running state judgment parameters of the human body use state lacked in an existing diagnosis system are complemented; the judgment result has a blocking type control characteristic; and the judgment layer and the execution scheme are structurally decoupled.

This invention discloses an automatic detection method, device, equipment, and medium for vehicle parking status at intersections. The method includes: when a vehicle is detected entering the intersection, acquiring trajectory point data consisting of multiple continuous trajectory points, including the current trajectory point; collaboratively determining whether the vehicle is parked based on the velocity, acceleration, and jerk of each trajectory point in the event window trajectory point data; and determining the parking status based on the parking duration when the vehicle is determined to be parked and its travel direction is consistent with the main traffic direction corresponding to the intersection. This invention accurately distinguishes between effective parking and low-speed creep scenarios through multi-point collaborative analysis, and eliminates interference by combining directional consistency verification. Without relying on additional hardware and high-precision maps, it achieves low-cost, high-precision, low-interference, and wide-coverage automatic detection and hierarchical early warning of parking behavior at intersections.

The application discloses a three-component geophone azimuth correction method and device based on multi-event fusion and probability weighting, equipment, medium and product, and relates to the technical field of geophysical exploration. The method is as follows: after at least two seismic signals recorded by a target three-component geophone and generated by at least two active source events are obtained, firstly, a preliminary azimuth calibration angle corresponding to each active source event is obtained, then a corresponding weight is assigned to the calibration angle according to a signal quality index calculated based on the corresponding seismic signal, then all calibration angles are fused according to all weights to obtain a final azimuth calibration angle, finally, the original horizontal component data is corrected by coordinate rotation using the final azimuth calibration angle to obtain corrected horizontal component data. Thus, by introducing a weighting mechanism based on signal quality, more accurate and reliable azimuth correction can be realized, the quality of seismic data and the reliability of subsequent interpretation are improved, and the application and promotion are facilitated.
