Title: Laser radar image processing system
Inventor: YAMADA OSAMU
IPC: G01S7/48
Filed: 1988-07-18
Abstract: PURPOSE:To effectively reduce the noise on a distance image measured by laser radar by performing speckle noise processing using reflected beam and blur noise processing using a parametric Wiener filter. CONSTITUTION:When the resolving power of laser radar is sufficiently smaller than one pixel, a point image 42 obtained by removing a speckle is used with respect to the image of the point object 41 measured by the laser radar. When the distance resolving power of the laser radar is larger than one pixel, a step object 43 is measured at first to obtain a step image 44. This image 44 is subjected to differentiation and Fourier transform while a component vertical to a stepping direction is extracted from the Fourier transform value to calculate a unidirectional component 45 of a blur function. By this method, step images in various directions are measured on an image and the directional components of respective blur functions are calculated and reconstituted to make it possible to specify a blur function 46.
