VARIABLE DISTORTION CORRECTION FOR PANORAMIC IMAGES
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.
The present technology is directed generally to industrial machine remote operation systems, devices, and methods. In some embodiments, an industrial machine remote operation system configured in accordance with embodiments of the present technology includes a control interface including one or more elements associated with remote operation of an industrial machine. In at least some embodiments, the control interface can include one or more indicators associated with motion and/or an orientation of the machine. Additionally, or alternatively, the control interface can include one or more indicators associated with motion and/or orientation of a component of the machine, such as a machine work tool.
A method for displaying a position of a boom-mounted implement relative to a swing indicator for an excavator having boom swing capabilities comprises displaying a propulsor icon of a set of propulsion units of the excavator on a display screen, displaying a housing icon of a housing of the excavator relative to the propulsor icon on the display screen, displaying a boom icon of the boom-mounted implement relative to the housing icon on the display screen, displaying the swing indicator relative to the propulsor icon on the display screen, updating a rotational position of the housing icon relative to the propulsor icon based on real-world movement of the housing relative to the set of propulsion units, and updating a location of the swing indicator relative to the propulsor icon based on real-world movement of the boom-mounted implement relative to the housing from the boom swing capabilities.
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.
