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.

This enables a very wild field of view, while preventing the unnatural appearance of objects near the edges of the image frame.

The collection member, the first side wall, the second side wall, and the plate member together define a hollow space. Further, at least one of the first side wall, the second side wall, and the plate member define an opening that communicates with the hollow space. The work implement further includes a sensor mounting system including a cover, a plurality of mechanical fasteners adapted to couple the cover with the work implement, and a sensor mounted on the cover. Upon coupling of the cover with the first side wall, the sensor is partially received within the hollow space.
E02F 3/34 - Dredgers; Soil-shifting machines mechanically-driven with digging tools mounted on a dipper- or bucket-arm, e.g. dippers, buckets with bucket-arms directly pivoted on the frames of tractors or self-propelled machines
A retaining mechanism includes a retainer with a skirt that has a surface of revolution with an axis of rotation. The skirt extends 180.0 degrees or less about the axis of rotation, forming a thru-slot. A drive portion extends axially from the skirt.
A lock includes a drive portion and a pin receiving portion. The drive portion includes a polygonal aperture, and the pin receiving portion includes a hole with an internal surface of revolution that defines an axis of rotation, a radial direction, a circumferential direction, and a slot extending at least partially through the pin receiving portion into the hole.
A lock assembly for attaching a wear member to a base includes a threaded retaining block with a C-spring attached to the retaining block that fits into an aperture of the base. A threaded lock pin fits into the aperture of the wear member, and the threaded aperture of the retaining block, retaining the wear member onto the base. The threaded lock pin engages the C-spring that prevents unintentional rotation of the threaded lock pin so that the threaded lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.
