Enhanced visibility system for work machines
An enhanced visibility system for a work machine includes an image capture device, a sensor, one or more control circuits, and a display. The image capture device is configured to obtain image data of an area surrounding the work machine. The sensor is configured to obtain data regarding physical properties of the area surrounding the work machine. The control circuits are configured to receive the image data and the data regarding the physical properties, and augment the image data with the data regarding the physical properties to generate augmented image data. The display is configured to display the augmented image data to provide an enhanced view of the area surrounding the work machine.
Work vehicle display systems and methods for generating visually-manipulated context views
A work vehicle display system utilized in piloting a work vehicle includes a display device having a display screen, a context camera mounted to the work vehicle and positioned to capture a context camera feed of the work vehicle's exterior environment, and a controller architecture. The controller architecture is configured to: (i) receive the context camera feed from the context camera; (ii) generate a visually-manipulated context view utilizing the context camera feed; and (iii) output the visually-manipulated context view to the display device for presentation on the display screen. In the process of generating the visually-manipulated context view, the controller architecture applies a dynamic distortion-perspective (D/P) modification effect to the context camera feed, while gradually adjusting a parameter of the dynamic D/P modification effect in response to changes in operator viewing preferences or in response to changes in a current operating condition of the work vehicle.
REMOTE OPERATION DEVICE, REMOTE OPERATION ASSISTANCE SERVER, REMOTE OPERATION ASSISTANCE SYSTEM, AND REMOTE OPERATION ASSISTANCE METHOD
A display mode of a picked-up image in a central image output device 2210 (specified image output device) is variably controlled so as to display all of respective specified portions PPL and PPR of a pair of pillars 4240L and 4240R configuring a cab 424 in the central image output device 2210 (specified image output device). The specified portions PPL and PPR are part of the pillars 4240L and 4240R overlapping a specified image region R that extends in a belt shape between left and right bezels 2210L and 2210R.
REMOTE OPERATION SUPPORT DEVICE AND REMOTE OPERATION SUPPORT METHOD FOR WORK MACHINE
A remote operation support device 100 is provided that is for improving the work efficiency of a remote operation performed by an operator, without fogging a front window 425F of a work machine 40 that is remotely operated by the operator. The remote operation support device 100 includes: a meteorological data obtaining unit 103 that obtains meteorological data at a designated time; an intra-cab temperature estimation unit 104; an intra-cab humidity estimation unit 105; a fogging determination unit 106; and an anti-fogging control unit 107. The anti-fogging control unit 107 performs an anti-fogging process for preventing the front window 425F from being fogged when a determination result by the fogging determination unit 106 is affirmative.
SAFETY MONITORING SYSTEM
To make it easier for an operator to notice an object in the surroundings of a construction machine. A safety monitoring system includes a detection device, a display unit, and a control unit. The detection device detects an object in the surroundings of the work vehicle. The display unit displays a captured image of the surroundings of the work vehicle. The control unit controls the detection device and the display unit. If the detection device detects an object, the control unit controls the display unit to display an image with a defined edge obtained by applying an edge-defining process to the image of the surroundings.
Management system
A management system includes a position detection unit which obtains a position of a work machine, a posture detection unit which obtains a posture of the work machine, an object detection unit which obtains a three-dimensional shape of a buried object, a position calculation unit which obtains a position of the buried object by using the position of the work machine obtained by the position detection unit, the posture of the work machine obtained by the posture detection unit, and the three-dimensional shape of the buried object obtained by the object detection unit, and an information acquisition unit which acquires buried object information including at least the position of the buried object obtained by the position calculation unit.
SYSTEM AND METHOD FOR ASSISTED POSITIONING OF TRANSPORT VEHICLES FOR MATERIAL DISCHARGE IN A WORKSITE
A system and method are provided for assisting transport vehicle drivers in material discharge for optimized working at a worksite by work machines such as dozers. A first user interface associated with the work machine accesses a map comprising three-dimensional data corresponding to at least a portion of the worksite. User input is received via the first user interface corresponding to desired discharge location(s) in the worksite to be worked, and output signals are generated for modifying a display on a second user interface associated with the transport vehicle, said modifications corresponding to the received user input and for directing the transport vehicle to the desired discharge locations. The two vehicles may share a common mapping unit such that input from the work machine is applied substantially in real-time at the transport vehicle. Alternatively, the inputs may be translated across mapping units to generate appropriate positioning instructions.
REAL-TIME SURFACE SCANNING AND ESTIMATION OF GROUND CHARACTERISTICS FOR GROUND COMPACTING WORK MACHINES
System and methods are provided for dynamic characterization of an area to be worked using a work implement of a work machine. First real-time data (e.g., surface scan data) are collected in a forward direction via a first sensor external to or onboard the work machine, and second real-time data (e.g., surface scan data) are collected for at least a traversed portion of the work area via a second onboard sensor. Characteristic values of a ground material in the work area are determined based on at least the first and second data corresponding to a given surface, and outputs are generated corresponding to at least a determined amount of material needed to achieve target values for the work area, based on at least one of the characteristic values. Certain characteristic values based on the real-time data may be used to estimate, among other things, how many truck loads are still required for the work area.
