This application provides a method for determining the positions of key points on a display device and the human body. This method eliminates traditional dedicated hardware such as sensors / radar during user posture data acquisition and processing, collecting data solely through a camera and directly acquiring the video stream using WebRTC technology natively supported by the browser, without requiring additional equipment. The human posture recognition model is integrated into the user device using TensorFlow.js, enabling on-device inference and avoiding data uploads to the cloud, thus eliminating transmission latency at its source. Model inference is completed on the browser side, accelerated by a web graphics library to improve processing efficiency and ensure real-time performance. The approximate positions of key points are located using the maximum probability of a heatmap, and then corrected using offsets to improve the positioning accuracy of human key points, further optimizing transmission efficiency and solving the problem of data transmission latency and its impact on transmission efficiency in current user posture data acquisition and processing.

The application provides a linkage drawing implementation method and device for building electrical design and a medium, and belongs to the technical field of building design. The method comprises the following steps: constructing a power distribution topology database; wherein the power distribution topology database is used for storing power distribution node data, topology relationship data and electrical appliance and cable combination data. Based on the power distribution topology database, load linkage calculation is performed through a preset rule engine, and corresponding selection data is determined to update the power distribution topology database according to the selection data; in response to a drawing request, based on the updated power distribution topology database, a structured data set corresponding to the power distribution node is determined, and the structured data set is mapped to a preset drawing display platform to generate corresponding system drawings. When it is determined that the parameters in the system drawings are changed, the corresponding changed parameters are written back to the power distribution topology database, and the load linkage calculation is re-executed through the preset rule engine and the selection data is determined to update the power distribution topology database and the system drawings.
