The present disclosure discloses a tripod for 3D modeling and a method for determining camera capture parameters, including the height and the direction of the camera lens. The tripod includes a telescopic rod, a mobile phone holder, a mounting support, and a floor stand. The telescopic rod is formed by multiple sections of nested hollow round rods, and the round rods can be extended and locked. The mobile phone holder is attached to the telescopic rod through a mobile phone holder install base. The mounting support is set on the top of the telescopic rod. The floor stand is set at the bottom of the telescopic rod. The telescopic rod is vertically set on a plane through the floor stand. There are three sets of the floor stand brackets that are evenly set around the telescopic rod. According to the present disclosure, contrasting colors are used at the bottom of the tripod where it touches the floor to help recognize these points. The height of the tripod can be accurately calculated by measuring the distance between these points in the image captured by the camera. The mobile phone holder is attached to the tripod, and a direction sensor of the mobile phone is used to record the direction during capture, so that the direction of camera capture can be obtained even when the camera does not have a direction sensor. The tripod features a simple structure, easy operation, low costs, and a compact storage which is easy to carry.
