Patent number: 7242791Abstract: A method and system for guiding a-vehicle comprises a location module for collecting location data for the vehicle. A vision module collects vision data for the vehicle. A maximum allowable correction duration and a maximum allowable vision-derived displacement are established for correction of a position of a vehicle. A location quality estimator estimates location quality data for the corresponding collected location data during an evaluation time window. A vision module estimates vision quality data for the corresponding collected vision data during the evaluation time window. A selector selects the application of location data or vision data based on the quality data and at least one of the maximum allowable correction duration and the maximum allowable vision-derived displacement for the evaluation time window or for an application interval trailing the evaluation time window.Type: GrantFiled: April 15, 2005Date of Patent: July 10, 2007Assignee: Deere & CompanyInventors: Shufeng Han, John Franklin Reid, Terence Daniel Pickett

Patent number: 7205904Abstract: A vehicle lane change aid system includes a detector that is operative to detect the presence of an other vehicle adjacent the vehicle, an indicator for providing an indication that a lane change maneuver of the vehicle may affect the other vehicle and a control receiving movement information of the vehicle. The control develops a position history of the vehicle at least as a function of the movement information. The control compares the detected presence of the other vehicle with the position history and provides an indication when a lane change maneuver may affect the other vehicle.Type: GrantFiled: April 18, 2005Date of Patent: April 17, 2007Assignee: Donnelly Corp.Inventor: Kenneth Schofield

Patent number: 6943824Abstract: A spout control system controls and aims a spout and a spout cap of a crop harvesting vehicle with respect to a separate crop hauling vehicle moving with the harvesting vehicle. The control system includes a video camera which is mounted on the cap and which views a field of view which includes a portion of the hauling vehicle. An image signal generated by the camera is received by an image processing unit. The image processing unit processes a digitized form of the image signal and automatically generates spout and cap control signals as a function thereof. Actuators automatically aim the spout and the cap in response to the control signal.Type: GrantFiled: March 13, 2002Date of Patent: September 13, 2005Assignees: Deere & Company, Albuquerque Real Time, Systems, Inc.Inventors: Barry Michael Alexia, Andrew Jackson Brislen, John Roderic Wicking, Walter James Frandsen, Jr.

Patent number: 6801244Abstract: A plurality of cameras respectively input an image from different camera positions. The plurality of cameras is on a moving object. An image memory stores a plurality of images input by the plurality of cameras. An image transformation unit transforms one image input by a first camera using each of a plurality of transformation parameters each representing a geometrical relationship among a predetermined plane, the first camera, and a second camera, and generates a plurality of transformed images from a view position of the second camera. A matching processing unit compares each of the plurality of transformed images with another image input by the second camera for each area consisting of pixels, and calculates a coincidence degree of each area between each transformed image and another image. An obstacle detection unit detects an obstacle area consisting of areas each having a coincidence degree below a threshold from another image.Type: GrantFiled: February 9, 2001Date of Patent: October 5, 2004Assignee: Kabushiki Kaisha ToshibaInventors: Nobuyuki Takeda, Hiroshi Hattori, Kazunori Onoguchi

Patent number: 6686951Abstract: An automatic vision guidance system for an agricultural vehicle is disclosed and described. The vision guidance system uses a K-means clustering algorithm in image processing to distinguish between crop and non-crop features. The vision guidance system utilizes moment algorithms to determine the location and orientation of crop rows, from which desired wheel angles are determined and steering is commanded. The vision guidance system may adjust the location and orientation of visually determined crop rows according to a predetermined distance between crop rows. Further, the vision guidance system may utilize a redundant number of regions of interest in determining crop row locations and orientations.Type: GrantFiled: February 28, 2000Date of Patent: February 3, 2004Assignee: Case, LLCInventors: Monte Andre Dickson, Bingcheng Ni, Shufeng Han

Patent number: 6671582Abstract: Agricultural operations by applying flexible manufacturing software, robotics and sensing techniques to agriculture. In manufacturing operations utilizing flexible machining and flexible assembly robots, work pieces flow through a fixed set of workstations on an assembly line. At different stations are located machine vision systems, laser based raster devices, radar, touch, photocell, and other methods of sensing; flexible robot armatures and the like are used to operate on them. This flexible agricultural automation turns that concept inside out, moving software programmable workstations through farm fields on mobile robots that can sense their environment and respond to it flexibly. The agricultural automation will make it possible for large scale farming to take up labor intensive farming practices which are currently only practical for small scale farming, improving land utilization efficiency, while lowering manpower costs dramatically.Type: GrantFiled: August 26, 2002Date of Patent: December 30, 2003Inventor: Brian P. Hanley

Patent number: 5974348Abstract: A precise automated work system and method is provided. One or more self-navigating robots can perform automated work operations with precision given six degrees of freedom in a undulating, sloping or irregular terrain, such as, a commercial truck garden. A self-propelled robot moves through the garden and performs gardening tasks following a specified course by dead-reckoning and periodically determining its position and orientation by a navigation fix. At least seven navigation beacons are positioned around a perimeter of a garden work area. Each beacon emits electromagnetic radiation across the garden for detection by the self-propelled robot. A panoramic image collector gathers and focuses electromagnetic radiation from each navigation beacon on an electronic camera to form at least seven beam spots.Type: GrantFiled: December 13, 1996Date of Patent: October 26, 1999Inventor: James K.
