ナビゲーション位置取得方法
Document Type and Number:
Japanese Patent JP4428766
Kind Code:
B2
Abstract:
A method and apparatus are provided for efficiently obtaining navigational position of a sensor array (22) based on a correlation between images captured by the sensor array at successive points in time. This is achieved by first acquiring a reference frame through said sensor array (22), successively acquiring a sample frame through said sensor array. Correlation data representing a relationship between the sample frame and the reference frame is then generated and a displacement of a reference feature contained in both the reference frame and the sample frame is determined based on the correlation data. The correlation surface of the correlation data is modelled as a general two-dimensional Taylor series expansion. The method and apparatus can be employed in a scanning device (10) to provide efficient scheme for obtaining navigational information based on a comparison of image frames captured by a sensor array of the scanning device at successive points in time.
