摘要： A system for uncovering a desired and pre-planned trench. A trenching machine is equipped with sensors, including visual imaging sensors. The sensors detect the inclination of the ground and movement of the trenching machine, as well as the angle of a trenching boom. Using this information, and a pre-determined preferred trench grade, a processor commands the trenching boom to adjust its angle to maintain the preferred trench grade. Surface irregularities may therefore be accounted for along the length of the trench to maintain a constant grade at the trench bottom.

摘要： A guidance system for remotely guiding a work machine along a virtual path. The system uses a vision system to capture image data representative of areas surrounding the work machine. The image data is used to produce a spatial map. Analysis of image data allows the work machine's then-current position to be represented on the spatial map. A virtual path extending from the work machine's position is next added to the spatial map. The virtual path may be generated in response to external input provided at the display showing an image of the spatial map. Using continuously-updated image data, the work machine is driven toward the virtual path. During operation, the actual path of the work machine is compared to the virtual path. If any deviation between the paths is detected, the trajectory of the work machine is automatically adjusted.
