Systems and methods for 3D image distification
摘要
說明書
In one embodiment, for example, the distify_frame function takes as input (as indicated by the file path of the filepath_in parameter) a single PLY file and creates the output feature vector for that file. The output feature vector can be output to the file path of the computer as indicated by the filepath_out parameter. The output feature vector can be generated by creating a k-d tree (a k-dimensional data structure to organize points in space with k dimensions) and querying the tree with the 2D image matrix created by the gen_coords function. When the k-d tree is queried, the output can include the distance to the nearest 3D point as describe herein. Thus, the distify_frame function can be used to provide the distance to the nearest 3D point to a 2D matrix point in the 2D matrix that was generated by the gen_coords function, as described herein. The coords parameter can be used to specify the coordinates of the 3D image (e.g., frame) to Distify or otherwise consider in a Distification process. The total_frames parameter can be used to specify a total number of frames to be Distified by the current call to the distify_frame function, such as, for example, one frame for a single 3D image or five frames for a movie comprised of multiple 3D images as described herein. Thus, for example, in some embodiments, Distification can be performed across a set of 3D files, for example, 3D PLY files. For example, in one embodiment, a set of related 3D files, for example, a set of 3D files related to frames of a 3D movie or sequential image capture may be provided to a multi-frame Distify function for processing.
