摘要： Disclosed is a technique for obtaining an estimate and variance of each variable based on a constraint manifold. Particles (or samples) are sampled in order to filter and fuse ambiguous data or information on at least one state variable of a system using the particles. The sampling is carried out in consideration of an influence which non-linearity of the constraint manifold of a system model, an observation model or another system model exerts on a probability distribution of the state variable. With this construction, it is possible to reduce decrease of fusion and filtering performance, decrease a Gaussian approximation error, and detect mismatched information.

摘要： A method and apparatus for estimating a state parameter in a nonlinear discrete time system are provided. The method for estimating a state parameter has the steps of (a) predicting a state parameter at a current time using an estimated state parameter at a previous time and a system dynamics; and (b) estimating an optimal state parameter at the current time from the state parameter predicted in the step (a) and a system output parameter measured at the current time, using a geometric data fusion method. Since the method and apparatus for estimating a state parameter have an excellent estimation performance particularly when nonlinearity is great or the error in an estimated initial value is big, the method and apparatus solve many problems, which cannot be solved by the conventional extended Kalman filter, and more improve the performance of estimating a state parameter, by analyzing the system characteristic and then appropriately utilizing constraints such as the operation range of the state parameter.

摘要： A 3D depth imaging method and system are disclosed. The 3D depth imaging method involves radiating light at a measurement target object using a projection means and imaging the light using an image receiving means, and includes the steps of assigning a unique transmitting side address to a signal corresponding to each pixel of the projection means to encode the signal; projecting multiple light patterns at the projection means to transmit the signal; receiving the encoded signal at the image receiving means; separating the received signal to restore the address; and determining a pixel position of the object using the transmitting side address and the restored address. With the 3D depth imaging method and system, it is possible to exactly separate signals received by the image receiving means even when the signals are overlap and the geometrical structure of the object varies, and it is also possible to obtain a depth image that is robust against ambient environmental noise.
