4 | Welcome to the OpenBiomechanics (OBP) Computer Vision (CV) Project! | |||||||
5 | The folders/files available in the OBP-CV dataset are: | |||||||
6 | ||||||||
7 | calibration_objects | Pictures of measuring tools - filenames contain the metadata of their measurements. Technical drawings included when available. | ||||||
8 | compressed_optitrack | Genlocked and synchronized videos from our Prime Color FS system, 8x cameras. Compressed using h264. | ||||||
9 | edgertronic_monochrome | Genlocked and synchronized videos from our Edgertronic SC1 (monochrome) system, 4x cameras. Compressed using h264. | ||||||
10 | iPhone | Single shot "slow-motion" iPhone videos shot at 240 FPS from an iPhone 13 Pro. | ||||||
11 | theia3d_output | Sample processed c3ds and overlays from our markerless software, Theia3d. (Note the c3d format may not be what you expect!) | ||||||
12 | ||||||||
13 | More details on the calibration objects: | |||||||
14 | - Calibration cube is 27.5 inches from red joint center to joint center with the middle joint center being exactly half the distance. | |||||||
15 | - CS-200 technical drawing has all dimensions required, standard OptiTrack object | |||||||
16 | - CW-500 technical drawing has all dimensions required, standard OptiTrack object | |||||||
17 | - Checkerboard is 5x8 with blue squares to denote orientation. Each square is 100mm in size. | |||||||
18 | ||||||||
19 | More details on the camera systems: | |||||||
20 | - Both the OptiTrack and Edgertronic systems are GENLOCKED and SYNCHRONIZED with global shutters. | |||||||
21 | - Edgertronic Wiki is strongly recommended reading: https://wiki.edgertronic.com/wiki/Specification | |||||||
22 | - OptiTrack Prime Color Wiki is strongly recommended reading: https://docs.optitrack.com/movement-sciences/prime-color-camera-setup/prime-color-setup | |||||||
23 | - iPhone 13 Pro uses a ROLLING SHUTTER. Important if you try any comparison methods. | |||||||
24 | - All shots happened in one session with no camera movement; you can assume the calibration objects are therefore representative of the capture volume | |||||||
25 | ||||||||
26 | Shot List Tabs have the video descriptions, frame rates, and other details - it is possible some frame rates may be slightly inaccurate. Double check! | |||||||
