This paper describes CAD tools for the construction of image database in IC chip analysis CAD system. For IC chip analysis by high-resolution microscopy, the image database is essential to manage more than several thousand images. But manual database construction is error-prone and time-consuming. In order to solve this problem, we develop a set of CAD toos that include image grabber to capture chip images, image editor to make the whole chip image database from the grabbed images, and image divider to reconstruct the database that consists of evenly overlapped images for efficient region search. we also develop an interactive pattern matching method for user-friendly image editing, and a heuristic region search method for fast image division. The tools are developed with a high-performance graphic hardware with JPEG image comparession chip to process the huge color image data. The tools are under the field test and experimental resutls show that the database construction time can be redcued in 1/3 compared to manual database construction.

A computer vision-based scene recognition algorithm is proposed for monitoring construction sites. The system analyzes images acquired from a surveillance camera to separate regions and classify them as building, ground, and hole. Mean shift image segmentation algorithm is tested for separating meaningful regions of construction site images. The system would benefit current monitoring practices in that information extracted from images could embrace an environmental context.

The research intends to exploit a strategy method of personal branding improving a personal value for construction of a personal image. As an assessment, the model of construction strategy of personal branding is developed in four steps of a model, construction of personal branding, by using elements of personal image and researching about personal branding strategy of scholars. In order to substantiate a validity of presented model, the case analyses of Martha Stewart. The strategy of four steps for construction of effective personal image is explained below. First step is an analysis of personal brand equity, deciding a direction of the concept of a personal branding through analyzing into a core value and core competence of one. Second step is a personal brand identity, constructing personal specification and identity with elements of personal image by using effective strategy, being able to be perceived to population. Third step is a personal brand positioning, constructing competitive brand image by using analysis of SWOT and strategy STP. Fourth step is a promotion of personal brand, advertising and extending a brand image of one by using a public activity and communication methods such as publication, mass media, and social network. By using the four kinds of processes, constructed strategy of a personal brand will be significant for construction of an effective personal image by having increment of a value and power of the brand.

The construction industry, which has a labour-intensive and conservative nature, is exclusive to adopt new technologies. However, the construction industry is viably introducing the 4th Industrial Revolution technologies represented by artificial intelligence, Internet of Things, robotics and unmanned transportation to promote change into a smart industry. An image-based artificial intelligence technology is a field of computer vision technology that refers to machines mimicking human visual recognition of objects from pictures or videos. The purpose of this article is to explore image-based artificial intelligence technologies which would be able to apply to the construction sites. In this study, we show two examples which is one for a construction waste classification model and another for cast in-situ anchor bolts defection detection model. Image-based intelligence technologies would be used for various measurement, classification, and detection works that occur in the construction projects.

건설산업은 GDP 17.5%를 차지하는 국내 경제의 중심을 담당하고 있는 기간산업이다. 하지만, 건설산업에 대한 이미지는 3D 업종, 비리와 부실 공사, 등의 부정적인 측면이 강하게 인식되고 있다. 이러한 건설산업의 이미지를 제고시키고 긍정적인 이미지를 구축하기 위하여 미국, 영국 등 주요 선진국가의 건설산업 이미지 제고 방향에 대하여 분석하고, 이를 국내에 적용시키기 위한 전략 개발을 제안하였다. 본 연구에서는 미국의 건설산업 이미지 향상을 위해 건설산업 전반의 이미지 향상을 위해 창설된 NCCER과 건설산업의 홍보와 참여를 목적으로 개발된 Build Your Future, Construction My Future, 등을 통하여 건설산업 이미지를 향상하기 위하여 노력하고 있다. 또한, 영국은 건설산업의 전반적 사항을 지원하는 CITB와 건설산업의 이미지 향상에 목적을 둔 Positive Image 2004 캠페인 프로그램, 등 선진국가들의 이미지 제고 사례를 포함한다. 국내에서도 관 산 학 연 상호협력에 기반을 둔 이미지 제고 노력의 필요성과 지속적인 홍보, 등을 통해 우수한 잠재 인재들을 확보하고, 전략적 분석을 통한 건설 이미지 제고운동에 지속적 노력을 가해야 할 것으로 사료되며, 본 연구의 해외벤치마킹 결과가 그 근간이 될 수 있을 것이다.

건설 산업은 국민 생활의 편의를 도모하고 산업의 기반시설을 구축하며 GDP의 약 17.5%를 차지할 정도로 국민 생활과 경제에 있어 중요한 위치를 차지하고 있는 국가 기반 산업이다. 그러나 건설 산업은 긍정적인 역할에도 불구하고 환경파괴, 저임금, 편향된 언론 보도 등으로 인하여 3D 업종, 비리, 부실, 비효율, 불신 등 부정적 이미지로 언론이나 일반 대중에게 투영되고 있는 것이 현실이다. 이로 인해 대학에서 건설관련 전공을 기피하는 현상이 발생하고 결과적으로 건설 산업으로 우수 인력 유입이 억제되고 있어 산업의 미래기반이 취약해 지고 있다. 또한, 건설 산업에 대한 R&D(Research and Development) 투자비 저조, 건설종사자들의 사기저하, 등 산업전반에 걸쳐 여러 문제점을 야기하고 있다. 본 연구는 건설산업이 21세기에 첨단산업의 하나로서 거듭나기 위해 건설 산업의 부정적인 이미지를 개선하고 우수인력과 연구개발을 위한 활발한 투자를 유치해 나가야 한다는 필요성에서 시작되었다. 특히, 건설 산업 이미지에 영향을 미치는 주요 요인을 체계적으로 찾아내어 구체적인 이미지 향상방안을 마련할 수 있는 기반을 마련하고자 하는데 초점을 맞추었다. 본 연구에서는 건설산업 이미지 영향요인 후보군을 도출하였고, 다양한 통계분석 기법을 활용하여 건설 산업 이미지 주요 영향 요인을 도출하였다. 연구 결과, 건설 산업 이미지에 영향을 미치는 정도는 건설업체 및 종사자의 도덕성, 건설업의 장래성이 가장 큰 영향을 미치는 것으로 나타났으며, 건설 산업 이미지 주요 영향 요인으로는 임금, 경제성장 기여도, 타 산업의 파급효과, 환경파괴성, 부동산투기 여부, 건설 종사자의 신뢰성, 건설업체의 장래 성장성, 건설업의 장래 부가가치성으로 분석되었다.

Construction performance and productivity improvement are key focus areas in construction industry for any nation. There have been frequent delays and cost overruns in construction projects and poor productivity is one of the major contributions. For this reasons, there have been many research studies performed on the improvement of construction productivity for several decades. However, measuring productivity on a construction job site is still not an easy work. Because collecting reliable data consistently from the job site requires a lot of personnel efforts causing extra time and cost. This paper provides a basic study on the application of image processing technology for measuring unit productivity. It presented the possibility of unit productivity measurement by image processing technology through case study.

In the modern, distributed and dynamic construction environment it is important to exchange information from different sources and in different data formats in order to improve the processes supported by these systems. Previous research has demonstrated that (i) a significant percentage of construction data is stored in semi-structured or unstructured data formats (ii) locating and identifying such data that are needed for the important decision making processes is a very hard and time-consuming task. In this paper, an automated methodology for the classification and retrieval of construction images in AEC/FM model based systems will be presented. Specifically, a combination of techniques from the areas of image processing, computer vision, and content-based image retrieval have been deployed to develop a method that can retrieve related construction site image data from components of a project model.

In a fire disaster in a tunnel, people should be rescued immediately using the information obtained from cameras or sensors. However, in heavy smoke from a fire, people cannot be clearly identified by a mounted CCTV, which is only effective in a clear environment. A thermal camera can be an alternative to this in smoky situations and is capable of detecting people from their emitted thermal energy. On the other hand, the thermal image camera has a smaller field of view than an ordinary camera due to its lens characteristics and temperature error, etc. In order to cover a relatively wide area, panoramic image construction needs to be implemented. In this work, a template-based similarity matching algorithm for constructing the panorama image is proposed and its performance is verified through experiments. This scheme provides guidelines for coping with difficulty in image construction, which requires an exact correspondence search for two images in cases of heavy smoke.
