  • Patent number: 9105092
    Abstract: In order for registration of images for surgery, first, a three-dimensional reference image of a surgical area of a patient before surgery is acquired. Then, a grating-pattern light is provided towards the surgical area to acquire a first measurement image. Thereafter, a preliminary registration is performed between the acquired first measurement image and a pre-acquired three-dimensional reference image. Then, a grating-pattern light is provided towards the surgical area after cutting out the surgical area to acquire a second measurement image. Thereafter, a fine registration is performed between the acquired second measurement image and the pre-acquired three-dimensional reference image based on the preliminary registration result. Thus, an accurate registration result may be acquired at low cost in a short period of time.

  • Patent number: 8442721
    Abstract: A steering controller for a movable robot is provided. The steering controller drives a plurality of motors, each of which is connected to a wheel. The wheels are spaced apart from each other in the circumferential direction with respect to an axis of a body of the movable robot. The steering controller comprises an input unit, an output unit and a conversion unit. The input unit receives steering signals including velocities of the movable robot according to the moving directions. The output unit outputs driving signals including rotational velocities of the motors. The conversion unit converts the steering signals to the driving signals. The use of the steering controller enables an operator to intuitionally steer the movable robot, making the movable robot convenient to use.
