For this aim, it is necessary for fire apparatus to swiftly move to fire scene by early detection. In addition, performing fire suppression after swift and accurate fire scene detection are required. Recently, researches on the method to determine whether fire has occurred or not through image processing by using deep learning and the method to determine the possibility of flame existence and unmanned vehicle are actively being conducted. This study introduces the method to determine fire occurrence through unmanned surveillance camera and suppressing it by unmanned fire fighting truck. First of all, Chapter 1 mentions recent research trends related to this study. Chapter 2 introduces the method regarding determining fire occurrence. The deep learning model used for fire detection constructed architecture by effectively using modified DCR block and CMFC block. By using multi-scale prediction based on flame size, determination of fire occurrence was more accurate and alarm malfunction rate was lower than existing methods. Chapter 3 suggested the method to determine road areas in which driving is possible so that unmanned fire fighting trucks can move fast and avoid obstacles. Chapter 4 suggested the method to perform vanishing point determination - a preprocess of lane recognition - so that driving in current lane is possible in road area. Afterward, fire occurrence area has to be identified once unmanned fire fighting truck arrives at a scene. Chapter 5 suggested fire segmentation model which identifies fire occurrence area through semantic segmentation. Lastly, the models used in performing such methods are generally known to require vast amounts of computations and memory. Therefore, Chapter 6 suggested a lightweight fire segmentation model which can be used in mobile devices. The suggested methods have been identified of their validity through respective experiments. Also, accuracy was identified based on evaluation metrics suitable for respective experiments. Through this, the proposed methods suggested in respective chapters have been identified to have greater accuracy compared to the recently published methods which used the algorithm-based method and using the deep learning method.ํ™”์žฌํ˜„์žฅ์—์„œ๋Š” ํ™”์žฌ๋ฅผ ์ดˆ๊ธฐ์— ๋ฐœ๊ฒฌํ•˜๊ณ  ์ง„์••์„ ํ†ตํ•ด ํ™”์žฌ๋กœ๋ถ€ํ„ฐ ์ธ๋ช…๊ณผ ์žฌ์‚ฐ์„ ๋ณดํ˜ธํ•˜๋Š” ๊ฒƒ์€ ์ƒ๋‹นํžˆ ์ค‘์š”ํ•œ ์—…๋ฌด์ด๋‹ค. ์ด๋ฅผ ์œ„ํ•ด์„œ๋Š” ํ™”์žฌ๋ฅผ ์ดˆ๊ธฐ์— ๊ฐ์ง€ํ•˜์—ฌ ํ™”์žฌํ˜„์žฅ์œผ๋กœ ์†Œ๋ฐฉ์‹œ์„ค์ด ๋น ๋ฅด๊ฒŒ ์ถœ๋™ํ•˜๋Š” ๊ฒƒ์ด ํ•„์š”ํ•˜๋‹ค. ๋˜ํ•œ, ํ™”์žฌ๋ฐœ์ƒ ์ง€์—ญ์„ ๋น ๋ฅด๊ณ  ์ •ํ™•ํ•˜๊ฒŒ ํŒ๋‹จํ•˜์—ฌ ํ™”์žฌ์ง„์••์„ ์ˆ˜ํ–‰ํ•˜๋Š” ๊ฒƒ์ด ์š”๊ตฌ๋œ๋‹ค. ์ตœ๊ทผ, ๋”ฅ๋Ÿฌ๋‹์„ ์‚ฌ์šฉํ•œ ์˜์ƒ์ฒ˜๋ฆฌ๋ฅผ ํ†ตํ•ด ํ™”์žฌ๋ฐœ์ƒ ์—ฌ๋ถ€๋ฅผ ํŒ๋‹จํ•˜๋Š” ๋ฐฉ๋ฒ•๊ณผ, ํ™”์—ผ์˜ ์กด์žฌ๊ฐ€๋Šฅ์„ฑ์„ ํŒ๋‹จํ•˜๋Š” ๊ธฐ๋ฒ• ๋ฐ ๋ฌด์ธ์ž๋™์ฐจ๋ฅผ ์‚ฌ์šฉํ•œ ํ™”์žฌ์ง„์••์— ๋Œ€ํ•œ ์—ฐ๊ตฌ๊ฐ€ ํ™œ๋ฐœํžˆ ์ง„ํ–‰๋˜๊ณ  ์žˆ๋‹ค. ์ด ๋…ผ๋ฌธ์—์„œ๋Š” ๋ฌด์ธ ๊ฐ์‹œ์นด๋ฉ”๋ผ๋ฅผ ํ†ตํ•ด ํ™”์žฌ์—ฌ๋ถ€๋ฅผ ํŒ๋‹จํ•œ ๋’ค, ํ™”์žฌํ˜„์žฅ์œผ๋กœ ๋ฌด์ธ ์†Œ๋ฐฉ์ฐจ๊ฐ€ ์ถœ๋™ํ•˜์—ฌ ํ™”์žฌ๋ฅผ ์ง„์••ํ•˜๊ธฐ ์œ„ํ•œ ๋ช‡๊ฐ€์ง€ ๊ธฐ๋ฒ•์— ๋Œ€ํ•˜์—ฌ ์†Œ๊ฐœํ•œ๋‹ค. ๋จผ์ €, 1์žฅ์—์„œ๋Š” ์ด ๋…ผ๋ฌธ๊ณผ ๊ด€๋ จ๋œ ์ตœ๊ทผ ์—ฐ๊ตฌ๋™ํ–ฅ์— ๋Œ€ํ•ด ์–ธ๊ธ‰ํ•œ๋‹ค. ๊ทธ๋ฆฌ๊ณ  2์žฅ์—์„œ๋Š” ํ™”์žฌ๋ฐœ์ƒ ์—ฌ๋ถ€ ํŒ๋ณ„์— ๋Œ€ํ•œ ๊ธฐ๋ฒ•์„ ์†Œ๊ฐœํ•œ๋‹ค. ํ™”์žฌ๊ฐ์ง€๋ฅผ ์œ„ํ•ด ์‚ฌ์šฉ๋œ ๋”ฅ๋Ÿฌ๋‹ ๋ชจ๋ธ์€ modified DCR block ๊ณผ CMFC block ์„ ํšจ๊ณผ์ ์œผ๋กœ ์‚ฌ์šฉํ•˜์—ฌ architecture๋ฅผ ๊ตฌ์„ฑํ•˜์˜€๋‹ค. ์ด๋ฅผ ํ†ตํ•ด, ํ™”์—ผ์˜ ํฌ๊ธฐ์— ๋”ฐ๋ผ multi-scale prediction์„ ์‚ฌ์šฉํ•จ์œผ๋กœ์จ ๊ธฐ์กด์˜ ๊ธฐ๋ฒ•์— ๋น„ํ•ด ๋” ์ •ํ™•ํ•œ ํ™”์žฌ๋ฐœ์ƒ์—ฌ๋ถ€ ํŒ๋ณ„๊ณผ, ๋” ๋‚ฎ์€ ๊ฒฝ๋ณด ์˜ค์ž‘๋™์œจ์„ ์ˆ˜ํ–‰ํ•˜๋Š” ๊ฒƒ์„ ํ™•์ธํ•˜์˜€๋‹ค. 3์žฅ์—์„œ๋Š” ํ™”์žฌํ˜„์žฅ์œผ๋กœ ์ถœ๋™ํ•˜๋ฉด์„œ, ๋น ๋ฅด๊ฒŒ ์ด๋™ํ•ด์•ผ ํ•˜๋Š” ๋ฌด์ธ์†Œ๋ฐฉ์ฐจ๊ฐ€ ์žฅ์• ๋ฌผ ํšŒํ”ผ๊ฐ€ ๊ฐ€๋Šฅํ•  ์ˆ˜ ์žˆ๋„๋ก ์ฃผํ–‰์ด ๊ฐ€๋Šฅํ•œ ๋„๋กœ์˜์—ญ์„ ํŒ๋ณ„ํ•˜๋Š” ๊ธฐ๋ฒ•์„ ์ œ์•ˆํ•˜์˜€๋‹ค. 4์žฅ์—์„œ๋Š”, ์ด๋™ ์ค‘ ์ฃผํ–‰๊ฐ€๋Šฅํ•œ ๋„๋กœ์˜์—ญ์—์„œ ํ˜„์žฌ ์ฐจ์„ ์„ ์œ ์ง€ํ•˜๋ฉฐ ์ฃผํ–‰ ๊ฐ€๋Šฅํ•˜๋„๋ก, ์ฐจ์„ ์ธ์‹์˜ ์ „์ฒ˜๋ฆฌ ๊ณผ์ •์ธ ์†Œ์‹ค์  ํŒ๋ณ„์„ ์ˆ˜ํ–‰ํ•˜๋Š” ๊ธฐ๋ฒ•์„ ์ œ์•ˆํ•˜์˜€๋‹ค. ์ดํ›„, ํ™”์žฌํ˜„์žฅ์— ๋ฌด์ธ์†Œ๋ฐฉ์ฐจ๊ฐ€ ๋„์ฐฉํ•˜๋ฉด ํ™”์žฌ๋ฐœ์ƒ ์˜์—ญ์„ ํŒ๋ณ„ํ•ด์•ผ ํ•œ๋‹ค. 5์žฅ์—์„œ๋Š” semantic segmentation์„ ํ†ตํ•ด ์ด๋Ÿฌํ•œ ํ™”์žฌ๋ฐœ์ƒ ์˜์—ญ์„ ํ™•์ธํ•  ์ˆ˜ ์žˆ๋„๋ก ํ•˜๋Š” fire segmentation ๋ชจ๋ธ์„ ์ œ์•ˆํ•˜์˜€๋‹ค. ๋งˆ์ง€๋ง‰์œผ๋กœ, ์ด๋Ÿฌํ•œ ๊ธฐ๋ฒ•๋“ค์ด ์ˆ˜ํ–‰๋˜๋Š” ๋ฐ ์‚ฌ์šฉ๋˜๋Š” ๋ชจ๋ธ๋“ค์€ ์ „์ฒด์ ์œผ๋กœ ๋งŽ์€ ์—ฐ์‚ฐ๋Ÿ‰๊ณผ ๋ฉ”๋ชจ๋ฆฌ๋ฅผ ์š”๊ตฌํ•˜๋Š” ๊ฒƒ์ด ์ž˜ ์•Œ๋ ค์ ธ ์žˆ๋‹ค. ๋”ฐ๋ผ์„œ 6์žฅ์—์„œ๋Š” ๋ชจ๋ฐ”์ผ ์žฅ์น˜์—์„œ ์‚ฌ์šฉํ•  ์ˆ˜ ์žˆ๋Š” ์ˆ˜์ค€์˜ ๊ฒฝ๋Ÿ‰ํ™”๋œ fire segmentation ๋ชจ๋ธ์„ ์ œ์•ˆํ•˜์˜€๋‹ค. ์ œ์•ˆํ•œ ๊ธฐ๋ฒ•์€ ๊ฐ๊ฐ์˜ ์‹คํ—˜์„ ํ†ตํ•ด ํƒ€๋‹น์„ฑ์„ ํ™•์ธํ•˜์˜€๋‹ค. ๊ทธ๋ฆฌ๊ณ , ๊ฐ ์‹คํ—˜์— ๋งž๋Š” ํ‰๊ฐ€์ง€ํ‘œ๋ฅผ ํ†ตํ•ด ์ •ํ™•๋„๋ฅผ ํ™•์ธํ•˜์˜€๋‹ค. ์ด๋ฅผ ํ†ตํ•ด, ๊ฐ ์žฅ์—์„œ ์ œ์•ˆํ•œ ๊ธฐ๋ฒ•๋“ค์€ ๋ชจ๋‘ ์ตœ๊ทผ์— ๋ฐœํ‘œ๋œ ์•Œ๊ณ ๋ฆฌ์ฆ˜ ๊ธฐ๋ฐ˜์˜ ๊ธฐ๋ฒ•๊ณผ, ๋”ฅ๋Ÿฌ๋‹์„ ์‚ฌ์šฉํ•œ ๊ธฐ๋ฒ•๋“ค์— ๋น„ํ•ด ๋†’์€ ์ •ํ™•๋„๋ฅผ ๊ฐ–๋Š” ๊ฒƒ์„ ํ™•์ธํ•˜์˜€๋‹ค.1 INTRODUCTION 1 1.1 Recent research on deep learning 1 1.2 Application: Deep learning in real life 7 1.2.1 Fire Detection 7 1.2.2 Road Segmentation 9 1.2.3 Vanishing Point Detection 10 1.2.4 Fire Segmentation 13 1.2.5 Model Compression for Fire Segmentation 14 1.3 Scenario for Automatic Fire Fighting Apparatus 16 2 Fire Detection 19 2.1 Related Work 19 2.2 Proposed Method for Fire Detection 23 2.2.1 Modified DCR block and CMFC block 23 2.2.2 Proposed Architecture for Fire Detection 24 2.2.3 Experimental Result 24 3 Road Segmentation 32 3.1 Related work 32 3.2 Proposed Method for Road Segmentation 34 3.3 Experimental Result 37 3.3.1 Data Augmentation 38 3.3.2 Evaluation 38 4 Vanishing Point Detection 42 4.1 Related Work 42 4.2 Proposed Method for Vanishing Point Detection 47 4.2.1 Proposed Architecture 47 4.2.2 Experimental Result 50 5 Fire Segmentation 54 5.1 Proposed Method for Fire Segmentation 54 5.2 Experimental Result 57 5.2.1 Result: FiSmo dataset 57 5.2.2 Result: Corsican Fire Database 61 6 Model Compression for Fire Segmentation 63 6.1 Related Work 63 6.2 Squeezed Model for Fire Segmentation 65 6.2.1 Proposed Architecture 65 6.2.2 Experimental Results 68 7 Conclusion 72 Abstract (In Korean) 84Docto
