Abstract
A method and system for acquiring photogrammetric data of a target object and generating a three-dimensional model of the target object is provided. The present disclosure provides a method and system for acquiring photogrammetric data of the target object while moving a camera along paths for optimal data acquisition. The present disclosure further provides a method and system for the efficient processing of the acquired photogrammetric data into a three-dimensional model.
Claims20
A method of acquiring photogrammetric data comprising:
- using a camera to capture consecutive images of a target object by moving the camera along at least five paths with a predetermined distance between each consecutive image;
- capturing each consecutive image along each of the at least five paths, wherein the at least five paths comprise an inner orbital pass, an outer orbital pass, a high bustrophedonic nadir pass, a bustrophedonic texture pass, and a bustrophedonic texture nadir pass;
- retaining the target object within a field of view of the camera when capturing each consecutive image;
- and
- generating photogrammetric data of the target object.
A method of acquiring photogrammetric data comprising:
- using a camera to capture consecutive images of a target object by moving the camera along six paths with a predetermined distance between each consecutive image;
- capturing each consecutive image along each of the six paths, wherein the six paths comprise an inner orbital pass, an outer orbital pass, a low bustrophedonic nadir pass, a high bustrophedonic nadir pass, a bustrophedonic texture pass, and a bustrophedonic texture nadir pass;
- and
- retaining the target object within a field of view of the camera when capturing each consecutive image;
- and
- generating photogrammetric data of the target object.
A computer implemented method of generating a three-dimensional model comprising the steps of:
- acquiring photogrammetric data of a target object including geometry imagery and texture imagery;
- creating tie points from geometry imagery and texture imagery;
- excluding the texture imagery from the geometry imagery;
- generating a dense point cloud from the geometry imagery;
- processing the dense point cloud into three-dimensional geometry;
- reducing a polygon count of the three-dimensional geometry;
- reintroducing texture imagery to the three-dimensional geometry and removing geometry imagery;
- creating textures by projecting texture imagery onto the three-dimensional geometry.
