Patent number: 10719955Abstract: The application provides a method of calibrating a camera of a vehicle. The vehicle has a reference frame. The method comprises taking an image of a scene by the camera. The ground plane of the vehicle is then determined according to features of the image. An origin point of the vehicle reference frame is later defined as being located on the determined ground plane. A translation of a reference frame of the camera is afterward determined for aligning the camera reference frame with the vehicle reference frame.Type: GrantFiled: October 13, 2017Date of Patent: July 21, 2020Assignee: Application Solutions (Electronics and Vision) Ltd.Inventors: Rui Guerreiro, Andreas Panakos, Carlos Silva, Dev Yadav

Patent number: 10652466Abstract: A method and a device for image stabilization of an image sequence of one or more cameras of a vehicle are disclosed. Images of the surroundings of the vehicle are recorded and image points of the recorded images are projected to a unit sphere, where the projection includes applying a lens distortion correction. For each of the one or more cameras, a vanishing point is calculated using the projected image points on the unit sphere and a motion of the vanishing point on the unit sphere is tracked. The motion of the vanishing point is used to calculate a corrected projection to a ground plane.Type: GrantFiled: August 16, 2017Date of Patent: May 12, 2020Assignee: APPLICATIONS SOLUTIONS (ELECTRONIC AND VISION) LTDInventors: Rui Guerreiro, Carlos Silva, Andreas Panakos, Dev Yadav

Patent number: 10346709Abstract: An enhanced object detecting method and apparatus is presented. A plurality of successive frames is captured by a monocular camera and the image data of the captured frames are transformed with respect to a predetermined point of view. For instance, the images may be transformed in order to obtain a top-down view. Particular features such as lines are extracted from the transformed image data, and corresponding features of successive frames are matched. An angular change of corresponding features is determined and boundaries of an object are identified based on the angular change of the features.Type: GrantFiled: July 18, 2017Date of Patent: July 9, 2019Assignee: APPLICATION SOLUTIONS (ELECTRONICS AND VISION) LTDInventors: Rui Guerreiro, Alexander Sibiryakov

Patent number: 10192141Abstract: This disclosure relates to a method in which points common to two or more of the images that appear to represent the same real world features are identified, and changes in the location of the points between respective images are used to deduce the motion of the camera and to find the position of the real world features in three dimensional space. In order to determine the scale of the three dimensional information, the position of a reference feature, whose actual distance from the camera is known, is found from the images. The reference feature is found by considering only candidate points selected from candidate points falling within a portion of the image corresponding to a part of the field of view of the camera. The scale is determined from the distance between the camera and the reference feature in the image and in real life.Type: GrantFiled: November 22, 2016Date of Patent: January 29, 2019Assignee: APPLICATION SOLUTIONS (ELECTRONICS AND VISION) LTD.Inventor: Robin Plowman
