494 results about "Standard Model" patented technology

A standard model creating apparatus which provides a high-precision standard model used for pattern recognition such as speech recognition, character recognition, or image recognition using a probability model based on a hidden Markov model, Bayesian theory, or linear discrimination analysis; intention interpretation using a probability model such as a Bayesian net; data-mining performed using a probability model; and so forth. The standard model creating apparatus includes a reference model preparing unit that prepares at least one reference model; a reference model storing unit that stores the reference model prepared by the reference model preparing unit; and a standard model creating unit that creates a standard model by calculating statistics of the standard model so as to maximize or locally maximize the probability or likelihood with respect to the reference model stored in the reference storing unit.

The invention discloses a three-dimensional transformer station semi-automatic reconstruction method based on laser point cloud data. The method comprises the steps: according to the existing standard of an electrical apparatus in the electric power industry, by collecting point cloud data and texture data of a transformer station, constructing a high-reality three-dimensional standard mode library of the electrical apparatus of the transformer station; by combining with the existing standard model of the transformer station, based on the laser point cloud data, performing ground feature extraction and identification, and automatically acquiring a position and a gesture of the electric apparatus in space; putting the three-dimensional electric apparatus into a corresponding point cloud three-dimensional scene, thereby completing vectorization of the point cloud data and further completing three-dimensional reconstruction of a transformer station scene. According to the three-dimensional transformer station semi-automatic reconstruction method based on the laser point cloud data, semi-automation of the three-dimensional reconstruction of the transformer station is achieved, and manual interference can be reduced, so that the production efficiency is improved, and the production cycle is shortened; by utilizing the precision advantage of laser point cloud, the precision of model products can be improved, and the whole simulation degree is high.
