With the usage of computer visual technology in civil engineering, pavement crack survey with imaging sensor gained wide attention past years. Unfortunately, it is still a challenge to achieve satisfying results. This paper presents approach based on edge detection for laser data. At first, LS-40 line-laser scanner implemented 3D surface advantage various depth information exhibited data, an enhanced fractional differential proposed segmentation. The method could effectively enhance boundary...
In recent years, with the rapid development of global demand and scale for deep underground space utilization, has gradually transitioned from single-purpose uses such as transportation, civil defense, commerce to a comprehensive, livable, disaster-resistant ecosystem. This shift brought increasing attention safety personnel flow in spaces. addressing challenges passenger prediction, irregular patterns, surges extreme conditions, large data dimensions, redundant features complicating model,...
Resolution is one of the important indicators that must be evaluated for low-light-level (LLL) image intensifiers. The traditional techniques evaluating this parameter include visual observation and objective testing. evaluation method has disadvantages strong uncertainty low accuracy, whereas existing testing mainly suffer from poor robustness. To address above problems, an automatic based on frequency spectrum analysis a two-dimensional (2D) matrix stripe pattern proposed. First, 2D with...
HUD (Head Up Display) image vibration detection requires the real-time performance. In this paper, after analyzing different algorithms for movement estimation of HUD, a new algorithm is studied based on feature extraction. algorithm, smoothing, an improved Canny operator proposed edge detection, then corner method applied to extract points edges. The testing results prove that works in and with high precision.
Sharpness is an algorithm used to sharpen images. As the increase of image size, resolution, and requirements for real-time processing, performance sharpness needs get improved greatly. The independent pixel calculation makes a good opportunity use GPU largely accelerate performance. However, transplant it GPU, one challenge that involves several stages execute. Each stage has its own characteristics, either with or without data dependency other stages. Based on those this paper proposes...
Integrated structural defects are one of the most common in microchannel plate fabrication and physicochemical treatment stage low-light-level (LLL) image intensifiers. Its appearance seriously affects imaging quality. The traditional evaluation method such is solely based on visual observation, its main disadvantages strong subjectivity large uncertainty. To address above problems, two objective methods integrated an LLL intensifier introduced. first local patch extreme, second frequency...
The purpose of this paper is to investigate the capabilities inexpensive theodolite created by authors, compared with modern commercial instruments, equipped a Leica TPS1203 robotic total station built-in GoPro Hero6 camera image sensors. This was tested in laboratory where simulated dynamic displacements were determined. results experimental tests showed that displacement errors and differences between test machine those detected range [Formula: see text][Formula: text]mm +0.13[Formula:...
