The measurement of implosion velocity is the core problem of inertial confinement fusion and it is also a key quantity of estimation of fusion ignition. A clear implosion trajectory X-ray image of hohlraum-radiative-driven CH-capsule is obtained in Sheng-GuangII laser facility with 1600 J laser energy, triple frequency 1 ns pulse width. KB-microscope coupled with X-ray streak camera whose temporal resolution is about 10 ps is used for diagnosis. The maximal velocity of implosion is about 160
