Abstract
A system and method for generating land maps of a land area. The land maps can include two-dimensional and three-dimensional land maps. The land maps may be efficiently generated based on field data obtained by mobile machines configured to traverse the land area, with the mobile machines associated with one or more sensors. The land maps may be used to accurately and efficiently guide other mobile machines as such mobile machines traverse through or operate within the land area.
Claims20
A mapping system for generating terrain-adjusted paths on a two-dimensional land map of a land area, said mapping system comprising:
- a mobile machine for traversing a path through the land area;
- at least one sensor associated with said mobile machine, wherein said sensor is configured to capture position data as said mobile machine traverses the path;
- and
- a mapping device comprising a processor and a non-transitory computer readable storage medium with a computer program stored thereon, wherein the computer program instructs the processor to perform the following steps—
- receive position data indicative of the path through the land area, wherein the position data may be used to generate a three-dimensional model path representative of the path in the land area,
- generate a reference path on the two-dimensional land map, with the reference path being indicative of the three-dimensional model path,
- determine a center point for the model path,
- partition the model path into a plurality of segments, with each segment including a segmentation point lying on the model path,
- determine a radial vector between the center point and each segmentation point, and
- generate one or more subsequent paths on the two-dimensional land map, with the subsequent paths being spaced apart from the reference path by a distance that is based, in part, on the radial vectors.
A mapping system for generating terrain-adjusted paths on a two-dimensional land map of a land area, said mapping system comprising:
- one or more computing devices configured to—
- receive position data from one or more position determining sensors, wherein the position data is indicative of a path through a portion of the land area,
- generate a three-dimensional model path representative of the path through the land area,
- project the model path onto the two-dimensional land map to obtain a reference path on the two-dimensional land map,
- determine a center point for the model path,
- identify a segmentation point lying on the model path,
- determine a radial vector between the center point and the segmentation point, and
- generate one or more subsequent paths on the two-dimensional land map, with the subsequent paths being spaced apart from the reference path by a distance that is based, in part, on an angle of the radial vector.
A mapping system for generating terrain-adjusted paths on a two-dimensional land map of a land area, said mapping system comprising:
- one or more computing devices configured to—
- receive position data from one or more position determining sensors, wherein the position data is indicative of two or more paths through a portion of the land area,
- generate a three-dimensional model path for each path through the land area,
- intersect the model paths with a datum plane, wherein the intersection of the datum plane at each model path corresponds with a segmentation point,
- determine a height vector between adjacent segmentation points, and
- generate one or more subsequent paths on the two-dimensional land map, with the subsequent paths being spaced apart from one another by a distance that is based, in part, on the height vector.
