Publication number: 20240017672Abstract: In mobile equipment that is configured for remote operation there are the competing interests of minimizing the number and complexity of cameras by using wide-angle cameras, while avoiding the fisheye distortion inherent in wide-angle cameras, which can be disorienting to remote operators. Thus, a method is disclosed that switches between video processing configurations depending on a machine state of the mobile equipment. For example, a first machine state may represent that the mobile equipment is immobile, whereas a second machine state may represent that the mobile equipment is mobile. In the first machine state, the video configuration does not correct for fisheye distortion, so as to maximize the field of view in the video while the mobile equipment is immobile. In the second machine state, the video configuration does correct for fisheye distortion, so as to prevent disorientation of the remote operator while the mobile equipment is mobile.Type: ApplicationFiled: July 18, 2022Publication date: January 18, 2024Applicant: Caterpillar Inc.Inventor: Aaron R.

Publication number: 20240020801Abstract: In panoramic video captured by a fisheye camera (e.g., for use in the remote operation of mobile equipment), there is a trade-off between the field of view and the level of distortion correction. In particular, to avoid the video from be disorienting, distortion correction is required. However, distortion correction applied to a very wide field of view results in an unnatural appearance of objects in edge regions, such that the image frames of the video must be cropped. A method is disclosed that varies the level of distortion correction that is applied to pixels in each image frame based on a position of those pixels in the image frame, such that less distortion correction is applied to pixels closer to edges of the image frame. This enables a very wild field of view, while preventing the unnatural appearance of objects near the edges of the image frame.Type: ApplicationFiled: July 18, 2022Publication date: January 18, 2024Applicant: Caterpillar Inc.Inventor: Aaron R.

Publication number: 20230359203Abstract: The state and stability of a machine and a threshold value for an acceptable level of the stability of the machine are determined based on different potential machine states or operations. Sensor inputs including machine speed and whether the machine is in a coasting mode, lift height of a payload, an articulation angle of the machine, a pitch angle, and a roll angle of the machine are used to generate a model for estimating a time series of values for the degree of stability of the machine by solving a physics-based equation or retrieving data from a database.Type: ApplicationFiled: May 5, 2022Publication date: November 9, 2023Applicant: CATERPILLAR INC.Inventors: Aaron R.

Publication number: 20230350412Abstract: In a mobile equipment with an articulated front portion having a worktool, a fisheye camera with a wide field of view, containing the front portion, is often mounted in a fixed direction on a rear portion of the mobile equipment. Thus, when the front portion moves (e.g., rotates) relative to the rear portion, a view around the front portion may be compromised due to inherent cropping in fisheye-distortion correction. Digital panning of panoramic video is disclosed that rotates a projection surface, in accordance with movement of the front portion, and generates a projected video on the projection surface, utilizing information that may have otherwise been cropped, to expand the visible area around the worktool. The digital panning in the projected video may mimic an operator turning their head to look down the longitudinal axis of the front portion while using the worktool.Type: ApplicationFiled: April 28, 2022Publication date: November 2, 2023Applicant: Caterpillar Inc.Inventors: Aaron R.

Patent number: 10041229Abstract: A system for controlling an operation of a machine is disclosed. The system includes an image capturing device and a controller. The image capturing device generates a signal indicative of a surrounding area of the machine. The controller is in communication with the image capturing device. The controller determines a preceding work cycle of the machine comprising a dig segment and determines a preceding segment associated with the preceding work cycle to be a dump segment. The controller further identifies a work aggregate within the surrounding area of the machine, when the preceding segment of the preceding work cycle is the dump segment. Further, the controller determines a distance between an implement of the machine and the work aggregate and issues a shift request to downshift a gear drive of a transmission system of the machine, if the distance is less than a predefined distance.Type: GrantFiled: November 2, 2015Date of Patent: August 7, 2018Assignee: Caterpillar Inc.Inventors: Zhijun Cai, Bradley K.

Patent number: 9938692Abstract: A payload weight of a load of material carried by an implement of a machine may be estimated taking into account angular acceleration of the payload. A lift cylinder pressure differential and a lift arm angular acceleration may be determined as the implement is raised through a weigh range. An angular acceleration compensation factor may be determined from the lift arm angular acceleration, and a compensated differential pressure may be calculated by multiplying the lift cylinder pressure differential by the angular acceleration compensation factor. The estimated payload weight may then be determined based on the compensated pressure differential and a head end cross-sectional area of the lift cylinder.Type: GrantFiled: January 4, 2016Date of Patent: April 10, 2018Assignee: Caterpillar Inc.Inventors: Aaron R.
