High-speed video analysis in quarry blasting

摘要

As part of their commitment to employing the latest technologies, Exchem Explosives have recently invested in a high-speed video camera to help with blast optimization and problem-solving activities. The camera selected for this task, an I-Speed IGB model manufactured by Olympus Industrial, was chosen because it allows the capture of high-resolution images (800 × 600 pixels) at a frame rate of 1,000 frames per second and with a shutter speed of 1 /1,000 of a second. This effectively means that the processes in the blast are frozen and can be followed in detail, revealing effects that are not normally visible to either the naked eye or with standard video footage.
