    摘要: An elongated member is provided with one or more imaging sensors, location sensors, and a switch in its bottom end. For example, in an embodiment the elongated member may be a walking stick and the one or more imaging sensors may be one or more cameras Such a walking stick takes pictures of its surrounding environment and keeps records of its location when the switch touches the ground, so that the pictures and location information can be used to create a virtual simulation of the area that a user of the walking stick has walked through.

    摘要: Embodiments of a system and method for tracking objects are described herein. Aspects of this disclosure efficiently update object “belief” data by creating a bitmap representation of object locations and velocities. The bitmap provides a three-dimensional representation of the object as viewed by one or more sensors. The bitmap representations are blended with sensor data over time to determine a current object belief state which can accurately account for asynchronous sensor data. Peaks in the belief data, which may be represented by pixels with an intensity value above a threshold value, are identified as likely objects. Additional sensor data is used to detect longitudinal velocities located at one or more of the peaks.

    摘要: An image display system and method that use physical models to produce a realistic display of a scene are disclosed. The image display method involves operating a computer having a display screen, a memory and a processing unit for simulating the motion of objects and displaying the results on the display screen. The method includes the steps of storing in the memory position and velocity parameters which define an initial state of a model system having a plurality of bodies, storing in the memory parameters which define at least one constraint function constraining the motion of the bodies in the model system, and calculating in the processor the position and velocity parameters which define the state of the system after a predetermined time step based on rigid body dynamics, including carrying out a semi-implicit integration step subject to the constraints, to determine the velocity after the step, including determining the constraint forces that act to keep the system in compliance with the constraints by ensuring that the first derivative of the constraint function is zero.
