Abstract

[PROBLEMS] To stably fix a relic in order to photograph each unfolded surface rotated exactly 90 degrees of a photograph used as a sketch when drawing a six-sided unfolded view of an archeological excavated relic; Provide a relic holder that can be rotated 90 degrees exactly. A relic holder has a pair of rectangular end surface members, and the end surface members are fixed to each other by four fixing bolts and have holes for holding a fixing plate. [Selection] Figure 1

Description

      The present invention relates to the structure of a relic holder used for taking photographs of archeological excavated relics.

Relics excavated from archeological excavations are generally drawn from a six-sided or three-sided view of the three-sided projection. In other words, a relic is placed in a posture in which the features of the relic appear best, and a front view, a top view, a rear view, a bottom view, and left and right side views in that posture are drawn. In this case, photogrammetry is a commonly used method. Photographs of each side are taken, and these pictures are used as a sketch to draw a shape.
On the other hand, the relic has a complicated and irregular shape and does not have a flat surface for stable installation. For this reason, when taking a picture of each side of the development view, for example, after taking the upper surface, it is necessary to rotate and re-install exactly 180 degrees in order to take the lower surface. Although it is placed on the lower side and supported, it tries to reproduce the exact position, but it cannot be installed accurately. At present, the photograph is taken in such a state, and the consistency of each development surface cannot be obtained.

  In order to easily and accurately photograph each side of the six-sided development of the relic, it is easy to hold a relic with a complicated irregular shape, and the retained relic is moved from 0 degrees (front view) to 90 degrees (top view). Figure), 180 degrees (rear view), and 270 degrees (lower view).

A relic holder that has both the function of maintaining the posture of the relic and the function of rotating to 90, 180, and 270 degrees.

The relic holder has rectangular and planar end surface members on both sides, and the end surface members are fixed to each other with four fixing bolts. Further, the end face member has a circular hole in the center, and a circular and planar relic fixing plate is incorporated in the main hole. The relic fixing plate can fix relics.
By fixing and holding the relic on the relic holder, the relic is held in a stable posture, and can be accurately rotated to 90 degrees, 180 degrees, and 270 degrees by the rectangular end surface member, and is parallel to the end surface member. The left and right sides can be directed toward the camera.

  The end face member has holes or screw holes through which bolts are passed at the four corners, and the end face members are arranged on both sides and fixed with bolts. In the center of the end face member, a circular hole for attaching a relic fixing plate is opened. The shape of the relic fixing plate is also circular, and the relic fixing plate can freely rotate in the end face member.

  Make two relic fixing plates to hold two places near the ends of the relic. The relic fixing plate is made of a soft material such as polystyrene foam or cardboard, and the cross-sectional shape of the relic sandwiching the relic can be easily opened. In order to more easily open the cross-sectional shape, the relics can be fixed in the same manner even if the relic fixing plate is divided into two and the relic cross section is opened. As for the cross-sectional shape of the relic, the posture to be installed is set in advance, and the cross-sectional shapes of the two holding places in the posture are opened in the relic fixing plate.

  In the method of fixing the relic, first, the relic is sandwiched between two relic fixing plates, and then the relic fixing plate is inserted into the hole of the end face member. The posture of the relic can be freely adjusted by rotating the relic fixing plate in the end face member.

  The accuracy and efficiency of archaeological relic measurement is improved. For example, when actually measuring a sculpture made of a tree branch, it is possible to easily and accurately photograph six surfaces of the relic by fixing it to the relic holder.
