SINGLE-CAMERA PARTICLE TRACKING SYSTEM AND METHOD

摘要

A method for tracking moving particles (112) in a fluid (114). The method includes illuminating (800) the moving particles (112) with an illumination sequence of patterns (200) generated by a light projector (120); measuring (802) with a single camera (110) light intensities reflected by the moving particles (112); calculating (806), based on the measured light intensity, digital coordinates (x', y', z') of the moving particles (112); determining (810) a mapping function f that maps the digital coordinates (x', y', z') of the moving particles (112) to physical coordinates (x, y, z) of the moving particles (112); and calculating (812) the physical coordinates (x, y, z) of the moving particles (112) based on the mapping function f. The illumination sequence of patterns is generated with a single wavelength, and light emitted by the projector is perpendicular to light received by the single camera.
