Containerless technique has many advantages for the density measurement of melts, such as high temperature and deep undercooling measurement. At present, many researchers focus on density measurement of melts with containerless technique and projection imaging method. In containerless experimental processes, the sphere melt droplet rotates and changes to spheroid, due to the asymmetrical of pressure of laser light and electrostatic force. In addition, there was no depth information is included in the image acquired from the droplet. Therefore, the accurate volume of droplet is difficult to obtain. Therefore, we proposed a new 3D reconstruction algorithmwith two cameras that acquired the droplet images simultaneously at different angles. The deviation of the novel algorithm is less than 1.1%. With the proposed algorithm, the density of liquid Zr is measured from 1800 K to 2500 K, the combined relative standard uncertainty in density is 1.80%. (C) 2020 Published by Elsevier B.V.
