Claim One:
1. A method for analyzing blasting video data comprising a plurality of video frames, the method comprising: modeling background data using a first set of video frames corresponding to images before a blasting event; masking at least some of the plurality of video frames according to the modeled background data to generate foreground video data representing deviations from the modeled background data; using at least one processor, determining an origin frame corresponding to a first occurrence of foreground video data in the plurality of the video frames; identifying blast outline coordinates based on the foreground video data of a second set of video frames including the origin frame and plurality of subsequent video frames; determining a highest point reached by a highest identified blast particle based on the blast outline coordinates in the second set of video frames; determining a blast highest point frame corresponding to the determined highest point; estimating a linear or parabolic blast expansion trajectory associated with the identified highest blast particle based on the blast outline coordinates of the second set of video frames; determining an original location of the identified highest blast particle, and identifying an original frame at which the identified highest blast particle initially moved from the original location based on the blast expansion trajectory and the second set of video frames; determining a travel time representing the time between the original frame and the blast highest point frame according to a frame rate of the blasting video data; estimating a maximum height associated with the identified highest blast particle based on the determined travel time; generating overlay indicia for replay of the blasting video data based on at least one of the determined highest point, the estimated linear or parabolic blast expansion trajectory associated with the identified highest blast particle, the determined original location of the identified highest blast particle, and the estimated maximum height associated with the identified highest blast particle; and rendering the blasting video data on a graphical display together with the overlay indicia.
