Introduction

The Tomo PIV system (3D3C) consists of four cameras, lasers, synchronization controllers, and high-frequency particle image velocimetry software, and supports instantaneous measurement of three velocity components at each point in a three-dimensional body.

Claims

1.High precision chromatographic calibration：Uniform conversion of the 4 camera images into a common coordinate system with sub-pixel accuracy and the use of digital calibration correction techniques to establish an accurate correspondence between object-space and image-space based.

2.High definition laminar imaging：4 cameras meet Scheimpflug conditions and have a depth of field greater than the sheet light thickness, ensuring that tracer particles in the measurement area are clearly in focus.

3.High definition 3D characterization：Based on a finite image space transient projection, a multiple algebraic reconstruction algorithm is invoked to obtain a three-dimensional grayscale field characterizing the distribution of tracer particles.

4.High precision image analysis：The method of multiple iterations and image deformation is used to improve the computational accuracy of particle velocity of 3D stereo images
