A system for determining a coverage region of a radar device is disclosed. The system may have one or more processors and a memory. The memory may store instructions that, when executed, enable the one or more processors to receive radar data generated by a radar device and lidar data generated by a lidar device. The radar data may include radar data points representing objects detected by the radar device and the lidar data may include lidar data points representing objects detected by the lidar device. The one or more processors may be further enabled to determine a radar coverage region for the radar device by comparing one or more radar data points to one or more lidar data points, and to generate data used to display a graphical representation of the radar coverage region.

Systems and methods for determining a radar device coverage region

A guidance system for a machine may include a scanning device configured to detect a presence of an object within a minimum desired distance of the machine, and a controller in communication with the scanning device. The controller may be configured to compare a number of times the object is detected during a time period to a number of times the object is permitted to be detected during the time period. The controller may be configured to adjust the number of times the object is permitted to be detected. Further, the controller may be configured to output an indication, when the number of times the object is detected is equal to or greater than the number of times the object is permitted to be detected, that the object is less than the minimum desired distance from the machine.

A method for generating a three dimensional grid of terrain includes receiving data representing a three-dimensional point cloud and generating a plurality of slices of the data. The method evaluates the slices using a swarm intelligence algorithm. The method is able to identify both terrain and objects. The terrain can also be identified as traversable terrain.

Mesh estimation of terrain

A control system for a mobile machine is disclosed. The control system may have a first sensor mounted on the mobile machine and configured to capture a first image of a region near the mobile machine, a second sensor mounted on the mobile machine and configured to capture a second image of the region, and a controller in communication with the first and second sensors. The controller may be configured to generate a stereo image from the first and second images, compute a disparity map of the stereo image, and generate an output to affect operation of the machine when a density of the disparity map is less than a threshold density.

Machine control system utilizing stereo disparity density

A guidance system for a mobile machine is disclosed. The guidance system may have a scanning device configured to generate a signal indicative of a lateral distance from the machine to a roadway marker, a locating device configured to determine a geographical location of the machine, and a controller in communication with the scanning device and the locating device. The controller may be configured to receive a desired lateral distance from the machine to the roadway marker, and to compare the desired lateral distance to the actual lateral distance. The controller may further be configured to implement a response to the comparison based on the geographical location.

A method and apparatus for providing an audible alarm signal. The method and apparatus includes creating a rectangular pulse signal having a desired period and a desired first amplitude, adding a shaped modulation component to the rectangular pulse signal from the desired first amplitude to a desired second amplitude to create a modulating waveform, creating a carrier signal, and combining the carrier signal and the modulating waveform to create the audible alarm signal.
