Latest Patents
One of his latest patents is focused on enhanced bundle adjustment techniques. This patent introduces novel tools and techniques that can be used to improve the effectiveness of photogrammetric tools, such as bundle adjustment. A key aspect of this innovation is a photo-observable backsight operation, which allows for the non-photographic observation of a target point's position. This observed position can then be utilized to constrain a pixel coordinate location of the same target point during a bundle adjustment operation. Additionally, another technique known as the photo-observable check shot operation enables the observed position of another target point to verify the validity of a bundle adjustment calculation. These techniques can be employed together or separately to enhance the overall process.
Another significant patent by Shaojun He involves the use of overlap areas to optimize bundle adjustment. This innovation provides novel tools and techniques for defining a search range for conjugate points in a set of images. One technique utilizes an intra-overlap area in two images to define a search range where a conjugate point can be located. This search range may be expressed as a distance range from a station where one or both images were captured. By narrowing the search range in an image captured from another station, this technique substantially reduces both the computation time required to identify a conjugate match and the likelihood of identifying an incorrect match.
