Provided is a controller (50) that includes a mechanical state acquisition section (400) that acquires information regarding a posture and an operation of a hydraulic excavator; a blind angle calculation section (500) that calculates a blind angle area from a seat in a cab (1f) of the hydraulic excavator based on the information indicating the posture and the operation of the hydraulic excavator and acquired by the mechanical state acquisition section (400); and a visibility level determination section (300) that determines a visibility level of an obstacle based on the blind angle area calculated by the blind angle calculation section (500) and a positional relationship calculated by a position relation calculation section (200). Further, a warning level determination section (600) of the controller (50) adjusts a warning level in accordance with the visibility level determined by the visibility level determination section (300).

Disclosed are a vehicle and a control method for the same. The vehicle includes a display unit configured to display information, a sensing unit configured to detect a moving object in the vicinity of the vehicle, and a controller configured to judge the motion characteristics of the moving object based on sensing information regarding the moving object provided from the sensing unit, the motion characteristics of the moving object including a speed and a movement direction of the moving object, to set a dangerous area for the moving object based on the motion characteristics of the moving object, the dangerous area having a size and a shape corresponding to the motion characteristics of the moving object, and to display an image indicating the dangerous area on the display unit.

A vehicle hitch assistance system includes a controller acquiring position data of a coupler of a trailer and deriving a vehicle path to align a hitch ball of the vehicle with the coupler including compensating for a determined change in the position of the coupler in a driving direction related to a difference between a vertical position of the coupler in the position data and a height of the hitch ball.

Method and apparatus are disclosed for distortion correction for vehicle surround view camera projections. An example vehicle includes cameras to capture images of a perimeter around the vehicle and a processor. The processor, using the images, generates a composite image of an area around the vehicle, and generates a depth map that defines spatial relationships between the vehicle and objects around the vehicle. The processor also generates a projection surface using the depth map. Additionally, the processor presents an interface for generating a view image based on the composite image projected onto the projection surface.

A vehicle hitching assistance system includes a controller executing an initial alignment process including searching for a trailer within a specified area of image data that is less than a total field of the image data in directions corresponding with both a longitudinal distance between the vehicle and the trailer and a lateral direction perpendicular to the longitudinal distance, presenting an indication to a driver of the vehicle to reposition the vehicle when the trailer is not identified within the specified area, and removing the indication when the trailer is identified within the specified area. The controller further executes an automated backing process upon identifying the trailer within the specified area, including identifying a coupler of the trailer and outputting a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler of the trailer during reversing.

An excavator includes a lower traveling structure, an upper swing structure swingably mounted on the lower traveling structure, an attachment attached to the upper swing structure, a display device, and a hardware processor. The display device is configured to display multiple ranges including a first range and a second range lower in stability degree than the first range in the working range of the attachment such that the multiple ranges are distinguishable. The hardware processor is configured to determine a setting with respect to the multiple ranges.

Disclosed herein is a display system including an image producing unit and an optical system part. The image producing unit produces an image on a display screen by letting a light beam, which eventually forms a virtual image based on the image produced, emerge from the display screen. The optical system part forms a left-eye image and a right-eye image on a user's left and right eyes, respectively, and thereby projects the virtual image toward a user's left and right eyes by reflecting and/or refracting the light beam emerging from the display screen. The optical system part has an image distortion generation factor to make an image distortion of the left-eye image different from an image distortion of the right-eye image.

A driver assistance apparatus according to an embodiment of the present invention includes: a first camera configured to capture a first video of the vicinity of a vehicle; a second camera configured to capture a second video of the vicinity of the vehicle; a processor configured to extract a first edge of an object included in a first stitching region in which the first video and the second video of the vicinity of the vehicle are connected; and a display unit configured to overlap and display the first edge and a synthetic video of the first and second videos of the vicinity of the vehicle except for the first stitching region, wherein the first stitching region is a fixed region included in the first video and the second video of the vicinity of the vehicle.
