Description

Nagrania wideo zrzutów manekina na pneumatyczny absorber energii (poduszkę powietrzną).

Zbiór danych zawiera 8 nagrań wideo dokumentujących zrzuty manekina z wysokości 2,5 m, 3,0 m oraz 4,5 m nad podłożem na pneumatyczny absorber energii o adaptowanej charakterystyce pracy.

Badania zrzutowe przeprowadzono w celu analizy zachowania manekina oraz absorbera podczas zrzutu, w szczególności w celu określenia warunków początkowych oddziaływania manekina z absorberem. Nagrania wideo wykorzystano do wyznaczenia prędkości manekina w chwili kontaktu z absorberem. Parametr ten stanowi jeden z parametrów niezbędnych do analizy obciążeń dynamicznych występujących podczas zrzutu.

Prędkość manekina wyznaczano na podstawie analizy nagrań wideo z wykorzystaniem metod wizji komputerowej, poprzez analizę przemieszczenia manekina w kolejnych klatkach nagrania oraz przeliczenie przemieszczenia w obrazie na jednostki przestrzenne.

Nagrania zawierają elementy umożliwiające określenie skali przestrzennej obrazu. W polu widzenia kamery znajdują się dwie szachownice kalibracyjne:

szachownica o dużym oczku, znajdująca się w odległości około 1800 mm od płaszczyzny zrzutu manekina; rozmiar oczka wynosi 100 mm,
szachownica o małym oczku, znajdująca się w przybliżeniu w płaszczyźnie zrzutu manekina; rozmiar oczka wynosi 30 mm.

Szachownice stanowią odniesienie przestrzenne umożliwiające wyznaczenie parametrów ruchu manekina na podstawie nagrań wideo.
