“…(Zrilic, 2006). Therein, the feedback control combined with the incremental encoder and the absolute magnetic encoder can effectively eliminate the real-time positioning error from the change in the pulse width (Banerjee et al , 2016; Putra et al , 2016). Furthermore, the high-speed and high-precision servo control system contributes to not only guaranteeing the accuracy of servo motor but also optimizing the whole transmission system (Cetinkunt, 1991).…”

“…The morphological gradient can obtain the edge detection of the source image and template image by comparing between the dilated image and the eroded image by which the strengthen intensity of pixels can highlight the periphery of the edge area (Cheng and Xiang, 2019; Shi et al , 2021; Jadin and Taib, 2012). Thereafter, the grayscale-based template matching algorithm (Putra et al , 2016) can accomplish the high-precision matching between the source image and the template image (Cheng and Xiang, 2019; Brunelli, 2009). The corresponding calculations of the template matching algorithm are listed in Table 2.…”

“…It is a method that sums the total differences of the gray level of each pixel between the template and the examined image. Suppose T is the template of size m × n and E is the examined image of size u × v, where u > m and v > n. SAD at point (x, y) in the examined image is defined as follows [33,34]:…”

Generating a Cylindrical Panorama from a Forward-Looking Borehole Video for Borehole Condition Analysis

et al. 2019

Geological exploration plays a fundamental and crucial role in geological engineering. The most frequently used method is to obtain borehole videos using an axial view borehole camera system (AVBCS) in a pre-drilled borehole. This approach to surveying the internal structure of a borehole is based on the video playback and video screenshot analysis. One of the drawbacks of AVBCS is that it provides only a qualitative description of borehole information with a forward-looking borehole video, but quantitative analysis of the borehole data, such as the width and dip angle of fracture, are unavailable. In this paper, we proposed a new approach to create a whole borehole-wall cylindrical panorama from the borehole video acquired by AVBCS, which provides a possibility for further analysis of borehole information. Firstly, based on the Otsu and region labeling algorithms, a borehole center location algorithm is proposed to extract the borehole center of each video image automatically. Afterwards, based on coordinate mapping (CM), a virtual coordinate graph (VCG) is designed in the unwrapping process of the front view borehole-wall image sequence, generating the corresponding unfolded image sequence and reducing the computational cost. Subsequently, based on the sum of absolute difference (SAD), a projection transformation SAD (PTSAD), which considers the gray level similarity of candidate images, is proposed to achieve the matching of the unfolded image sequence. Finally, an image filtering module is introduced to filter the invalid frames and the remaining frames are stitched into a complete cylindrical panorama. Experiments on two real-world borehole videos demonstrate that the proposed method can generate panoramic borehole-wall unfolded images from videos with satisfying visual effect for follow up geological condition analysis. From the resulting image, borehole information, including the rock mechanical properties, distribution and width of fracture, fault distribution and seam thickness, can be further obtained and analyzed.
