Faster R-CNN을 이용한 갓길 차로 위반 차량 검출

고명진,박민주,여지호 한국ITS학회 2022 한국ITS학회논문지 Vol.21 No.1

최근 5년간 고속도로에서 발생한 사망 사고의 통계를 살펴보면, 고속도로 전체 사망자 중 갓길에서 발생한 사망자의 사망률이 약 3배 높은 것으로 나타났다. 이는 갓길 사고 발생 시 사고의 심각도가 매우 높다는 것을 보여주며, 갓길 차로 위반 차량을 단속하여 사고를 미연에 방지하는 것이 중요하다는 것을 시시한다. 이에 본 연구는 Faster R-CNN 기법을 활용하여 갓길 차로 위반 차량을 검출할 수 있는 방법을 제안하였다. Faster R-CNN 기법을 기반으로 차량을 탐지하고, 추가적인 판독 모듈을 구성하여 갓길 위반 여부를 판단하였다. 실험 및 평가를 위해 현실세계와 유사하게 상황을 재현할 수 있는 시뮬레이션 게임인 GTAV를 활용하였다. 이미지 형태의 학습데이터 1,800장과 평가데이터 800장을 가공 및 생성하였으며, ZFNet과 VGG16에서 Threshold 값의 변화에 따른 성능을 측정하였다. 그 결과 Threshold 0.8 기준 ZFNet 99.2%, Threshold 0.7 기준 VGG16 93.9%의 검출율을 보였고, 모델 별 평균 검출 속도는 ZFNet 0.0468 초, VGG16 0.16초를 기록하여 ZFNet의 검출율이 약 7% 정도 높았으며, 검출 속도 또한 약 3.4 배 빠름을 확인하였다. 이는 비교적 복잡하지 않은 네트워크에서도 입력 영상의 전처리 없이 빠른 속도로 갓길 차로 위반 차량의 검출이 가능함을 보여주며, 실제 영상자료 기반의 학습 데이터셋을 충분히 확보한다면 지정 차로 위반 검출에 본 알고리즘을 활용할 수 있다는 것을 시사한다. According to the statistics about the fatal crashes that have occurred on the expressways for the last 5 years, those who died on the shoulders of the road has been as 3 times high as the others who died on the expressways. It suggests that the crashes on the shoulders of the road should be fatal, and that it would be important to prevent the traffic crashes by cracking down on the vehicles intruding the shoulders of the road. Therefore, this study proposed a method to detect a vehicle that violates the shoulder lane by using the Faster R-CNN. The vehicle was detected based on the Faster R-CNN, and an additional reading module was configured to determine whether there was a shoulder violation. For experiments and evaluations, GTAV, a simulation game that can reproduce situations similar to the real world, was used. 1,800 images of training data and 800 evaluation data were processed and generated, and the performance according to the change of the threshold value was measured in ZFNet and VGG16. As a result, the detection rate of ZFNet was 99.2% based on Threshold 0.8 and VGG16 93.9% based on Threshold 0.7, and the average detection speed for each model was 0.0468 seconds for ZFNet and 0.16 seconds for VGG16, so the detection rate of ZFNet was about 7% higher. The speed was also confirmed to be about 3.4 times faster. These results show that even in a relatively uncomplicated network, it is possible to detect a vehicle that violates the shoulder lane at a high speed without pre-processing the input image. It suggests that this algorithm can be used to detect violations of designated lanes if sufficient training datasets based on actual video data are obtained.

Characteristics of Pt thin films on WC substrate fabricated by ion beam-assisted DC magnetron sputtering for a lens glass mold

고명진,박순섭 한양대학교 세라믹연구소 2016 Journal of Ceramic Processing Research Vol.17 No.1

Pt thin films with a Cr or Ti interlayer were deposited onto a tungsten carbide (WC) substrate by ion beam-assisted directcurrent (DC) magnetron sputtering. The percentage composition of Cr and Ti underneath the Pt films varied and the completethin film characteristics were used to categorize specimens. Microstructure and surface analysis of the specimens wereconducted by scanning electron microscopy (SEM), X-ray diffractometry and atomic force microscopy. Mechanical propertiessuch as hardness and adhesion strength of Pt thin films were also examined. Interlayers of pure Ti or Cr were formed withthicknesses of 40 nm and 50 nm, respectively. The growth rates of both Cr and Ti thin films were similar when exposed to thesame deposition conditions. Analysis of the specimen SEM images revealed that all Pt thin films investigated, irrespective oftarget composition, had anisotropic grains with a dense columnar structure. Hardness and adhesion strength values of the Cr/Pt thin films were higher than those of the Ti/Pt thin films.

This study was carried out as a survey on the level of lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in 5 items of agricultural products (lettuce, pumpkin, head lettuce, cabbage and crown daisy) for which safety guidelines are not yet established in Korea. The 407 samples were collected from local markets in 9 regional places and the levels of metals were measured by ICP-MS and mercury analyzer. The average levels of Pb, Cd, As and Hg were 0.026, 0.018 ,0.008 and 0.003 mg/kg for lettuce, 0.002, 0.001, 0.001 and 0.0006 mg/kg for pumpkin, 0.002,0.005, 0.001 and 0.0005 mg/kg for head lettuce, 0.001, 0.002, 0.0002 and 0.0006 mg/kg for cabbage and 0.022, 0.014,0.006 and 0.004 mg/kg for crown daisy. For risk assessment, the daily dietary exposures of Pb, Cd and Hg by intake of these agricultural products were calculated and compared with PTWI (provisional tolerable weekly intake) established by JECFA. The daily dietary exposure of heavy metals by intake of these agricultural products were 0.13, 0.56and 0.09% of PTWI, respectively. These monitoring results will be utilized as fundamental data for the establishment of Korean standards of Pb, Cd, As and Hg in 5 items of agricultural products and valuable source for DB construction for science-based safety control of heavy metals in foods including agricultural products.

유동층 화학기상증착법으로 제조된 TRISO 피복입자의 ZrC 층 미세구조와 경도에 미치는 증착온도의 영향

고명진,김대종,김원주,조문성,윤순길,박지연,Ko, Myung-Jin,Kim, Daejong,Kim, Weon-Ju,Cho, Moon Sung,Yoon, Soon Gil,Park, Ji Yeon 한국세라믹학회 2013 한국세라믹학회지 Vol.50 No.1

Tristructural-isotropic (TRISO)-coated particles were fabricated by a fluidized-bed chemical vapor deposition (FBCVD) method for use in a very high temperature gas-cooled reactor (VHTR). ZrC as a constituent layer of TRISO coating layers was deposited by a chloride process using $ZrCl_4$ and $CH_4$ source gases in a temperature range of $1400^{\circ}C$ and $1550^{\circ}C$. The change in the microstructure of ZrC depending on the deposition temperature and its effect on the hardness were evaluated. As the deposition temperature increased to $1500^{\circ}C$, the grain size of the ZrC increased and the hardness of the ZrC decreased according to the Hall-Petch relationship. However, at $1550^{\circ}C$, the ZrC layer was highly non-stoichiometric and carbon-rich and did not obey the Hall-Petch relationship in spite of the decrease of the grain size. A considerable amount of pyrolytic carbon at the grain boundaries of the ZrC as well as coarse granular pyrolytic carbon were locally distributed in the ZrC layer deposited at $1550^{\circ}C$. Therefore, the hardness decreased largely due to the formation of a large amount of pyrolytic carbon in the ZrC layer.

건물 외벽체 현장 열저항과 열관류율 평가를 위한 평균법의 수렴성 지표 분석

고명진,문지훈,김용식 한국생활환경학회 2019 한국생활환경학회지 Vol.26 No.4

This study analyzed the convergence of the in-situ thermal resistance (R-value) and thermal transmittance (U-value) obtained by the average method using criteria of ISO 9869-1 and ASTM C1155-95. Onsite measurement was conducted for an northwest-facing opaque exterior wall of a 30-year-old apartment house over a period of three weeks during winter. The in-situ R-value and U-value obtained at the end of the test are 51.1% smaller and 113.0% larger than the theoretical values calculated according to the ISO 6946. These results show that identifying the in-situ thermal performance of exterior walls is important for building energy efficiency. When using criteria of ASTM C1155- 95, the minimum measurement duration was 3 days, but the results of this period showed a deviation of approximately 10% from the values at the end of the test. On the other hand, the convergence conditions of ISO 9869-1 were satisfied continually from 17 days after the start of measurement. Therefore, the findings show that the convergence criteria of ASTM C1155-95 can reduce the test duration but it is possible to derive the results with lower confidence level, whereas the convergence criteria of ISO 9869-1 increases the test duration but can produce a more reliable results.

Intrathecal baclofen pump implantation for complex regional pain syndrome in a patient with a spinal cord stimulator: consideration about optimal location of intrathecal catheter tip - A case report -

고명진,이현성,조현지,김성록,전상윤,이상은 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.2

Intrathecal baclofen (ITB) pump implantation can be used to control dystonia and severe pain associated with complex regional pain syndrome (CRPS) with or without a spinal cord stimulator (SCS). A 45-year-old female patient had gotten an SCS to control the pain of CRPS. However, she suffered from chronic intractable pain in her left ankle and foot despite paresthesia in the entire painful area because the effectiveness of the SCS gradually diminished over time. In a trial of intrathecal drug administration, baclofen was superior to morphine for pain relief, had fewer side effects, and was superior in terms of patient satisfaction. To achieve the greatest degree of pain relief from the ITB pump, the tip of the intrathecal catheter was carefully placed in relation to the SCS. Over a oneyear follow-up period, the patient experienced mild pain without any adverse effects.
