The 2D Motion Image Measurement and Analysis System (MIAS) is designed to track, measure, and visualize the motion trajectories of selected targets in image sequences. It supports the measurement of key kinematic parameters, including position, velocity, acceleration, angle, angular velocity, angular acceleration, and displacement. Measurements can be performed automatically, manually, or using marker based identification tracking, depending on the application scenario. Trajectories are displayed synchronously with the original images, and the measurement results can be output as charts and numerical tables for intuitive analysis.
