Abstract
A system for automated mosaic-based vector editing comprising a mosaic imaging server that assembles image tiles to form larger image mosaics while correcting the image tiles for tonality and other visual characteristics, a vector analysis server that analyzes vector information, a routing calculation server that calculates routes from the vector information, and a rendering engine that produces visualizations from the routing information, and a method for image mosaic creation and correction.
Claims10
A system for advanced vector editing, comprising:
- a vector analysis server comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to:
- analyze a plurality of vector points retrieved from a storage;
- and
- provide the results of analysis as output;
- a vector routing calculation server comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to:
- receive vector analysis information from the vector analysis server;
- calculate vector route information based at least in part on the received vector analysis information;
- provide the vector route information as output;
- and
- provide the vector route information to a vector database for storage;
- and
- a rendering engine comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programming instructions, when operating on the processor, cause the processor to form visualizations based at least in part on the vector routing information received;
- wherein the calculation of vector route information comprises:
- calculating a three-dimensional vector path according to epipolar geometry;
- determining a new three-dimensional location based at least in part on the raster data and the three-dimensional vector path calculation;
- updating a stored vector projection via the epipolar geometry;
- and
- creating an image mosaic based on the stored vector projection.

A method for advanced vector editing, comprising the steps of:
- positioning, using a rendering engine comprising at least a memory, a processor, and a plurality of programming instructions stored in the memory and operating on the processor thereof, a cursor on a raster image displayed on a viewer;
- calculating, using a vector routing calculation server comprising at least a memory, a processor, and a plurality of programming instructions stored in the memory and operating on the processor thereof, a radius around the cursor;
- positioning the radius in contact with a vector path on the raster image;
- and
- recalculating the vector path through the cursor location within the radius;
- wherein the recalculation of the vector path comprises:
- calculating a three-dimensional vector path according to epipolar geometry;
- determining a new three-dimensional location based at least in part on the raster data and the three-dimensional vector path calculation;
- updating a stored vector projection via the epipolar geometry;
- and
- creating an image mosaic based on the stored vector projection.
