AlphaPose-real-time full-body multi-person pose estimation and tracking system

It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.

Lubricating oil detection based on dielectric principle

This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.

Two-degree-of-freedom pan-tilt robot control platform

This work, titled "Two Degrees of Freedom Pan-Tilt Robot Control Platform", implements a complete pan-tilt robot control platform. The system uses motion sensors as control handles to control the movement of the robot, and cooperates with the OLED screen to display the system's Current status. Using the control handle, you can control the movement of the vertical axis servo through forward and backward movements, and control the movement of the horizontal axis servo through rotation operations, thereby realizing two degrees of freedom control of the robot.

AC current measurement system based on STM32 (program, circuit information)

The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.
