In this paper, we propose the development of an integrated intelligent parking control system using a 360° camera that has overcome the shortcomings of the existing parking control system. The system proposed in this paper consists of six items as follows. First, license plate recognition software when entering the vehicle, second, real-time parking space identification software using 360° image, third, real-time precision parking guidance software based on deep learning vehicle motion recognition, fourth, multi-license-plate recognition software using 360° image, fifth, real-time parking position identification software using 360° image, sixth, database server etc. Performance evaluation results were high in both recognition rate and time spent, and efficiency was confirmed.

일시 수확형 고추를 직파하였을 때, 이랑 형태와 파종 거리 및 파종 깊이에 따른 수량차이는 인정되지는 않았다. 그러나 파종 시기를 앞당겨 4월 8일에 120×20㎝로 파종하였을 때 수량이 10a당 266㎏로써 높은 경향을 보였으며, 이랑 형태에 따른 파종 깊이는 120㎝의 이랑에서 0.3㎝ 깊이로 파종하였을 때가 수량이 10a당 334.8㎏으로 가장 높은 경향을 보였는데 이는 입모율이 74%로 높아짐에 따른 것으로 보이며, 터널 재배를 했을 경우 수량이 10a당 288㎏로 노지 재배보다 높았고 입모율도 향상되었다. Direct seeding of hot pepper can save labor comparing with the method that use transplants. The objective of this study was to evaluate effects of seeding space, depth, date, and low tunnel cultivation on yields of once-over harvested hot pepper (‘Jalapeno’ × ‘Indo’ and ‘9837059’). Hot peppers were direct-seeded in single or double rows at various seeding depths on several planting dates. Seeds also were sown inside and outside plastic tunnels. There were no significant effects of seeding space, depth and date on plant stand or yield, although early seeding and shallow seeding depths tended to increase both these variables. The best treatment combinations for plant stand and yield was using a double row 60 ㎝ apart (on a 120 ㎝ wide bed) with 20 ㎝ in-row spacing and 0.3 ㎝ planting depth. Low tunnel cultivation also increased stand rate and yield of hot pepper.
