Guide systems for indicating a distance between a first object and a second object and a method for visually representing a distance between two objects as the distance reduces are provided. A sensor measures a distance between the first object and the second object. A processor receives a distance measurement from the sensor and determines whether the distance measured by the sensor is within one of a plurality of distance intervals. Upon determining that the distance is within one of the plurality of distance intervals, the processor displays a distance indicator on the display. The distance indicator is located on the display based on the distance according to a scale for the distance interval, where a display area on the display represents the distance interval. The scale for the distance intervals becomes finer as the distance between the first object and the second object decreases.

In one example, a distance sensor includes a projection system. A light receiving system, and a processor. The projection system includes a plurality of laser light sources arranged in an array to emit a plurality of beams of light that forms a grid-shaped projection pattern when the plurality of beams of light is incident on a surface and a compensation optic to minimize a magnification-induced curvilinear distortion of the grid-shaped projection pattern before the plurality of beams of light is incident on the surface. The light receiving system captures an image of the grid-shaped projection pattern on the surface. The processor calculates a distance from the distance sensor to the surface, based on an appearance of the grid-shaped projection pattern in the image.

A system for display and interaction includes an interface and a processor. The interface is configured to receive data from one or more sensors. The processor is configured to convert the data to a common synthetic data space; provide the common synthetic data space for display; and receive a command associated with an object represented in the common synthetic data space. In some embodiments, the processor is coupled to a memory that stores instructions for the processor.

A system and method are provided for determining mistrack conditions in work vehicles such as excavators having first and second tracks. A controller uses data from onboard sensors (e.g., cameras, lidar) having an external field of view to detect a first position of, e.g., a track of the work vehicle relative to a first external point in a local reference system independent of a global reference system and to detect, upon the work vehicle having advanced from the detected first position a predetermined distance, a second position of the at least first component of the work vehicle relative to a second external point in the local reference system. The controller further determines an amount of mistrack error corresponding to a difference between the detected second position and an expected second position, and generates an output signal based on the determined amount of mistrack error.

A driver assistance system for a vehicle includes a rear-view camera constructed and arranged to obtain an image of an area behind a rear of the vehicle. A non-camera sensor system is constructed and arranged to obtain data regarding dynamic or static environmental features at opposing sides of the vehicle. An electronic control unit is electrically connected with the rear-view camera and with the sensor system. The electronic control unit is constructed and arranged to create an image from the data received from the sensor system. A display system is controlled by the electronic control unit and is constructed and arranged to display simultaneously to a driver of the vehicle at a single location, the image obtained by the rear-view camera and the image created by the electronic control system.
