With the recent increase in the autonomous vehicle industry, research on self-driving technology has been actively conducted on specially equipped vehicles such as buses and trailers or commercial vehicles, beyond research on autonomous driving based on general passenger vehicles. In particular, the trailer has a tracker part that a person drives and a trailer part that carries luggage. In general, in forward driving, only the length of the vehicle is a little longer, and there is no difficulty in driving. However, when driving in reverse, steering is difficult because the steering angle is opposite to that of a general vehicle. The most important part in reverse driving is the detection of the hitch angle, which is the connection part between the tracker and the trailer. Therefore, this paper aims to detect the trailer hitch angle using the rear camera, which is a low-cost sensor attached to a tracker vehicle, not an encoder or expensive sensor.

The purpose of this study was to derive practical improvement measures for the food traceability system that could improve food reliability and secure food safety. To this, in our survey May-June, 2019, 567 adult males and females were analyzed for recognition and experience of the food traceability system, measures to improve the system, and intention to make additional payments to improve the system. In the case of a food safety accident, 2.54 of 5 points were given on if the food was recalled or not. Approximately 77.4 percent of the respondents had never seen indication of a food traceability system, and approximately 93.8 percent had no access to, or experience with, using the system. Most respondents said that the food traceability system should be applied to items that need to be applied. As the volume of data that is recorded and managed by the government is recognized as high, improvement is needed. Finally, it was analyzed that the company intends to pay an additional 1.34% on average to expand its food traceability system. A more sophisticated cost analysis is needed to apply the improvements proposed to complement the plans that are acceptable to consumers and the industry.
