This paper proposes a parking space detection method for autonomous parking by using the Around View Monitor (AVM) image and Light Detection and Ranging (LIDAR) sensor fusion. This method consists of removing obstacles except for the parking line, detecting the parking line, and template matching method to detect the parking space location information in the parking lot. In order to remove the obstacles, we correct and converge LIDAR information considering the distortion phenomenon in AVM image. Based on the assumption that the obstacles are removed, the line filter that reflects the thickness of the parking line and the improved radon transformation are applied to detect the parking line clearly. The parking space location information is detected by applying template matching with the modified parking space template and the detected parking lines are used to return location information of parking space. Finally, we propose a novel parking space detection system that returns relative distance and relative angle from the current vehicle to the parking space.

주차장에서 빈 공간을 분석하는 기술은 주차공간의 효율적인 사용이나 교통이 혼잡한 곳에서 유용하게 사용될 수 있다. 그러나 기존의 주차 공간 분석 방법은 실용적이지 못하거나 빠른 처리속도가 필요하다. 그래서 본 논문에서는 실시간 주차검출에 적합한 주차 모니터링 방법을 제안하고자 한다. 제안된 방법은 그레이레벨 영상을 이용하여 주차여부를 확인하고, 주차공간을 분석하는 방법을 사용하였다. 제안된 방법의 성능을 확인하기 위해 야외 주차장에서 129개의 동영상을 획득하여 실험한 결과 98.5%의 주차 공간 분석에 성공하여 제안된 방법이 주차 공간 분석에 효율적인 것을 입증하였다.

도시의 급속한 발전과 인구유입에 따른 차량의 증가로 부족한 도시의 주차 공간에 대한 효율적인 관리가 필요하고 사용자에게 보다 편리함을 제고할 필요가 증대되고 있다. 그러나 기존의 주차장 관리시스템은 공간적 및 시간적으로 제한되어 있거나, 편리함을 제공하지 못하고 있다. 본 논문에서는 광역의 분산된 주차 공간 관리서비스에 LPWA기반의 통신, IoT 클라우드를 구축하여 주차 공간 관리서비스에 대한 효율화 및 편리성을 높이도록 제안한다. 주차 센서는 주차장의 주차 공간 정보를 수집하며 저전력 광역 네트워크를 통해 전송되며, 모든 주차 데이터는 IoT 클라우드에서 처리되고 분석되어, 주차 공간관리 서비스 시스템을 통하여, 도시의 사람들에게 주차 가능 면적을 확인하도록 하여 시간적인 편리함과 주차 공간에 대한 면적 효율화를 제공한다.

The increase in vehicle purchases worldwide is having a very significant impact on the availability of parking spaces. In particular, since it is difficult to secure a parking space in an urban area, it may be of great help to the driver to check vehicle parking information in advance. However, the current parking lot information is still operated semi-manually, such as notifications. Therefore, in this study, we propose a system for detecting a parking space using a relatively simple image processing method based on an image taken from the sky and evaluate its performance. The proposed method first converts the captured RGB image into a black-and-white binary image. This is to simplify the calculation for detection using discrete information. Next, a morphological operation is applied to increase the clarity of the binary image, and a template mask in the form of a bounding box indicating a parking space is applied to check the parking state. Twelve image samples and 2181 total of test, were used for the experiment, and a threshold of 40% was used to detect each parking space. The experimental results showed that information on the availability of parking spaces for parking users was provided with an accuracy of 95%. Although the number of experimental images is somewhat insufficient to address the generality of accuracy, it is possible to confirm the possibility of parking space detection with a simple image processing method.

The purpose of this study is just for parking shall identify the status of the lack of rental apartments to relieve parking shortages. Next performed, and subsequent utilization of space just outside the parking space expansion plan is to present an alternative. Analysis of the study only 30 of the direction of the plan and set standards according to the nature of each complex. Planned urban planning aspects and architectural aspects of a parking space that can expand and classify the types of features will be discussed. Suggestions on how to take advantage of the parking space that can expand only in state owned lands in the urban planning aspects. The Architectural Planning of the side lot line change in the space and change the use of the Common Service Facilities or just to change the internal road system, by changing the way of parking, secure parking space. This way of working to improve the environment of the complex, at least. Actually just the space of improvement to be made with the opinion of the residents and the surrounding areas of the business association, must be preceded by a feasibility study.

The purpose of this research is to analyze the planning characteristics based on the physical quality indicators and the users' satisfaction of parking space in apartment housing through the case study of 36 housing estate samples which were built in 1994-1998. The contents of this research consists of three main parts. The first part is to analyze the characteristics of residential environment based on the quality indicators of parking space in apartment housing. The second part is to analyze the correlation of quality indicators of parking space and development conditions in apartment housing. The third part is to analyze the correlation of users' satisfaction and physical quality indicators of parking space, and to propose the planning methods which increase the quality of residential environment of parking space in apartment housing.

There are several ways to solve parking problem in the downtown. One of them is to manage parking efficiently, that is, to raise use-efficiency of parking place and to help in the block efficiently, it can prevent disproportion that some parking space is over capacity and the other parking one is under. It causes not only the disproportion of economic efficiency but also the congestion of local road. The precondition to manage parking efficiently is to analyse the parking characteristics. In this paper we build up total D/B by collecting every information about parking space. We developed the Parking Management System by using RFID and Sensor. The efficient Parking Management System is for convenience of drivers and efficient usage of parking space. And this system is also the basic study to be developed as the total Parking Management System by upgrading every information.

This study aims to analyze the parking demand in general hospitals in Chunju. The survey is done to examine the capacity of parking, the time of parking, the frequency of parking, and the actual condition of parking space. As a results of analysis, the conclusion was derived that the parking space is not satisfactory compared to the desired level. Consequently, this study aims to represent the improved parking based on characteristics of parking systems and the practical uses of the parking space in general hospitals.

With the rate of spread of motors rapidly increased, but parking difficulties in an apartment complex was aggravated due to an insufficient parking lot. Visual interference on residential environment, various kinds of pollution and noise, decrease of open space in an apartment complex are also causes of parking difficulties. Therefore, this study is to suggest a theory of desirable direction for planning of the parking space by studying psychological characteristics of users' behaviors by the type of the circulation of motors and pedestrians. Consideration on the present situation, real conditions of underground parking space and the consciousness and parking habit of residents, the most important problem is required in this study.
