As one of the most typical flow structures in hypersonic flow, the hypersonic turbulent boundary layer (TBL) is of great significance in the optimization of the aerodynamic configuration design of hypersonic vehicles. The nano-tracer-based planar laser scattering technique was utilized to obtain velocity results of the fully developed hypersonic (Mach 6.0) TBL. The scale-invariant feature transformation algorithm was used to obtain velocity information. Based on the results of mean velocity and fluctuating velocity distribution, the feasibility of this method has been verified.
