摘要： PROBLEM TO BE SOLVED: To provide an image pickup device for a boring bore capable of positively picking up the image of the internal wall of the bore by cleaning a specified area in the bore including an image pickup position so as not to impede image pickup. SOLUTION: This image pickup device for a boring bore has a head part 2 with a camera part 3 built therein. Expansive partition bodies 4 are disposed in two specified parts of the head part 2, and a fresh water supply means and a mixed muddy water discharge means are connected to two specified parts of the outer periphery of the head part 2 held between two partition bodies 4. The head part 2 is inserted in the boring bore 50, and a specified area around the head part 2 is partitioned and isolated by the expansion of the partition bodies 4, and fresh water injection and mixed muddy water discharge are performed in the isolated specified area around the head part 2 to positively obtain transparency between the head part 2 and the internal wall of the boring bore 50 so as to obtain a clear image of the internal wall of the boring bore 50. The image can therefore be picked up even in the case of mixed muddy water staying in the boring bore 50.

摘要： PROBLEM TO BE SOLVED: To display an entire circumferential expansion image of a hole wall face in terms of not only a still image but also a dynamic image by conducting coordinate transformation at a high speed in the case of picking up a hole wall face such as a boring hole and underground water and expanding the entire circumferential image. SOLUTION: Digitized image data are stored in an image memory 54 for each frame with a write memory data controller 53, and a read memory address controller 55 is used to read alternately data of odd and even number fields for many number of times at a speed of 60 times per sec from contents of the image memory 54. In this case, while referring to azimuth data of an image pickup image outputted from an azimuth meter, image data are read in spiral under the control of a coordinate transformation table 56. Then image data expanded in a square graph are converted into an analog signal by a D/A converter 57 and a video signal is outputted through an RGB matrix circuit 58.

摘要： PROBLEM TO BE SOLVED: To form the image of a rock layer under the ground surface by collecting the signal having the two-dimensional display of a stratum via a stratum fluid, and characterizing the nature of the stratum based on the reflected energy of the stratum. SOLUTION: A probe 104 is coupled with the wall of a stratum, and a stratum fluid is guided into a tool from the stratum. A camera controller has focus control and zoom control, and it gives the expanded image of a bored wall 106 to the detection plane of a camera via a relay optical system 114. A process electronics 126 corrects the image collected by a camera heat or the optional signal having the two-dimensional display of the stratum to be transferred to a data controller on the ground surface and transmits the signal indicating the feature of the stratum segment received by a wire line cable. This device corrects the nonuniform picture cell responsiveness and realizes such a function as the emphasis of the two-dimensional signal with the signal processing technique.
