本発明は、孔壁の定方位全周画像を観察撮影し、さらに
連続した孔壁全周の展開画像が作製できる孔壁展開画像
作製装置と展開画像作製の方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a hole wall developed image production device and development capable of observing and photographing a fixed directional all-around image of a hole wall, and further producing a continuous developed image of the entire circumference of the hole wall. The present invention relates to a method for producing images.

あった。(Prior Art) In geological surveys, it is necessary to know the inclination and continuity state of surface elements such as strata surfaces, joint surfaces, and crack surfaces. For this reason, a borehole television camera is used that directly observes the hole wall of a hole drilled by poling, but a borehole camera that images the hole wall by projecting it onto a plane mirror tilted at an angle of 45 degrees with respect to the hole wall is used. Because the range in which enemy shadows could be seen was limited, it was difficult to know the overall ground condition.

孔壁の展開画像を得る方法（特開昭５８−２２３１１３
号参照）などがある。In order to know the overall ground condition from the borehole wall, it is good to create a developed image of the borehole wall.This method is as follows: ■ A method of combining the images taken by the borehole TV camera mentioned above into a mosaic shape; A method of collectively photographing a group of observation optical fibers arranged in a radial planar manner (see Japanese Patent Application Laid-open No. 57-7211@publication). A method of illuminating a light beam, converting this reflected light into an electrical momentum signal, scanning the polling hole wall, and obtaining a developed image of the hole wall by raising and lowering the sonde (Japanese Patent Laid-Open No. 58-223113)
(see issue).
しかし、■による方法は吊り下げているケーブルにねじ
れが生じるため、各画像の撮影方位を正しく決めるため
には各々の画像に対して方位測定の手間を要し、かつ、
数多くの画像を合成するため簡便な方法とは言い難い。However, method (2) causes twisting in the hanging cable, so it requires time and effort to measure the direction of each image in order to correctly determine the shooting direction of each image.
It is difficult to say that it is a simple method because it combines a large number of images.
また、■による方法は、展開画像が各観測用光ファイバ

ことによって決定しているが、方位計の指針の動きの遅
れや揺れによっても画像のゆがみを生じる欠点がある。In addition, in method (■), the developed image is taken through each optical fiber for observation, so if the distance between the hole wall and the tip of the optical fiber changes due to the unevenness of the wall of the poling hole, the range photographed by each optical fiber for observation will change. There is a drawback that it is not possible to obtain a continuous image as a whole because the image changes. In addition, in the method (2), the hole wall is scanned by raising and lowering the sonde, so it is necessary to keep the sonde's raising and lowering speed constant, and if vibrations occur due to the expansion and contraction of the cable in the direction of raising and lowering the sonde, the image will be distorted. Furthermore, although the direction of the light beam is determined by detecting deviation from the north pole direction, there is a drawback that image distortion may occur due to delay or shaking of the pointer of the compass.
さらに該方法では走査された画像は固定されてしまうた
め、…裂からの湧水の状況などを動的画像として観察す
ることは困難である。Furthermore, since the scanned image is fixed in this method, it is difficult to observe the state of spring water from the fissure as a dynamic image.

いる。(Problems to be Solved by the Invention) In view of the above circumstances, the present invention aims to observe the condition of the hole wall using a fixed-direction all-around image sent directly from the sonde, and at locations where a developed image of the hole wall is required. The aim is to create a continuous unfolded image regardless of wall irregularities or changes in diameter.
