Abstract
Electronic devices and/or operating methods of the electronic device to provide visual localization based on outdoor three-dimensional (3D) map information may be provided. Such electronic devices may be configured to acquire two-dimensional (2D) image information about an outdoor environment, generate 3D map information about the outdoor environment based on the 2D image information, and determine a position of a point in the 3D map information corresponding to a query image.
Claims17
An operating method of an electronic device, the method comprising:
- acquiring, using a processor included in the electronic device, two-dimensional (2D) image information about an outdoor environment;
- generating, using the processor, three-dimensional (3D) map information about the outdoor environment based on the 2D image information;
- and
- determining, using the processor, a position of a point in the 3D map information corresponding to a query image.
An electronic device comprising:
- a memory;
- and
- a processor configured to connect to the memory and to execute at least one instruction stored in the memory, the processor further configured to,
- acquire two-dimensional (2D) image information about an outdoor environment,
- generate three-dimensional (3D) map information about the outdoor environment based on the 2D image information, and
- determine a position of a point in the 3D map information corresponding to a query image.
A non-transitory computer-readable record medium storing instructions that, when executed by a processor, cause a computer to implement a visual localization providing method, the visual localization providing method comprising:
- acquiring, using the processor, two-dimensional (2D) image information about an outdoor environment;
- generating, using the processor, three-dimensional (3D) map information about the outdoor environment based on the 2D image information;
- and
- determining, using the processor, a position of a point in the 3D map information corresponding to a query image.
