Patent Number Title Of Patent Date Issued
5063604 Method and means for recognizing patterns represented in logarithmic polar coordinates November 5, 1991
Image processing method and apparatus wherein candidate points are first selected in a log-polar image domain. The points may be selected by edge detection, thresholding, or any method suitable for identifying image points which are likely to lie on some feature of interest. For every
5051906 Mobile robot navigation employing retroreflective ceiling features September 24, 1991
Apparatus and method which provides for the determination of a vehicle's orientation and position in an environment, such as a hallway, from an image of a retroreflective ceiling feature. A mobile robot 10 includes a light source 28 and a camera 12 that are pitched up obliquely at an
5040116 Visual navigation and obstacle avoidance structured light system August 13, 1991
A vision system for a vehicle, such as a mobile robot (10) includes at least one radiation projector (14, 16) which projects a structured beam of radiation into the robot's environment. The structured beam of radiation (14a, 16a) preferably has a substantially planar pattern of sufficien
4979136 Processing system and method for enhancing image data December 18, 1990
A non-linear digital filter system for image data or other signal data suppresses undesirable noise while enhancing significant characteristics of the data. Data elements in a neighborhood (window) defined around and including an input data element are classified into characteristic clas
4954962 Visual navigation and obstacle avoidance structured light system September 4, 1990
A vision system for a vehicle, such as a mobile robot (10) includes at least one radiation projector (14, 16) which projects a structured beam of radiation into the robot's environment. The structured beam of radiation (14a, 16a) preferably has a substantially planar pattern of sufficien
4905151 One dimensional image visual system for a moving vehicle February 27, 1990
A vision system for a mobile robot 10 comprises an optical sensor subsystem 20 which generates a substantially one dimensional image of an environment, a signal processing subsystem 24 for extracting and enhancing significant vertical visual features from the one dimensional image and a
