摘要:

在交通安全与道路维护领域,精确检测道路损伤对于保障安全驾驶和延长道路耐久性至关重要。然而,当前方法往往因数据有限而表现不足。此前已有研究尝试使用生成对抗网络(GAN)生成具有多样形状的损伤,并人工将其整合到合适位置。但该问题尚未得到充分探索,并面临两个挑战。第一,这些方法仅丰富了损伤的位置和形状,而忽略了严重程度级别的多样性,且真实感仍需进一步改进。第二,它们需要大量人工操作。为应对这些挑战,我们提出了一种创新方法。除了使用GAN生成具有不同形状的损伤外,我们还进一步采用纹理合成技术提取道路纹理。然后将这两个元素以不同权重混合,使我们能够控制合成损伤的严重程度,再通过泊松融合将其嵌入回原始图像中。我们的方法既保证了损伤严重程度的丰富性,又实现了与背景更好的对齐。为节省人工成本,我们在嵌入过程中利用结构相似性进行自动化样本选择。每张原始图像的增强数据包含具有不同严重程度级别的版本。我们实施了一种直接的筛选策略以缓解分布漂移。实验在一个公开道路损伤数据集上进行。所提出的方法不仅消除了对人工劳动的需求,还取得了显著提升,将mAP提高了4.1%,F1分数提高了4.5%。

英文摘要:

In the domain of traffic safety and road maintenance, precise detection of road damage is crucial for ensuring safe driving and prolonging road durability. However, current methods often fall short due to limited data. Prior attempts have used Generative Adversarial Networks to generate damage with diverse shapes and manually integrate it into appropriate positions. However, the problem has not been well explored and is faced with two challenges. First, they only enrich the location and shape of damage while neglect the diversity of severity levels, and the realism still needs further improvement. Second, they require a significant amount of manual effort. To address these challenges, we propose an innovative approach. In addition to using GAN to generate damage with various shapes, we further employ texture synthesis techniques to extract road textures. These two elements are then mixed with different weights, allowing us to control the severity of the synthesized damage, which are then embedded back into the original images via Poisson blending. Our method ensures both richness of damage severity and a better alignment with the background. To save labor costs, we leverage structural similarity for automated sample selection during embedding. Each augmented data of an original image contains versions with varying severity levels. We implement a straightforward screening strategy to mitigate distribution drift. Experiments are conducted on a public road damage dataset. The proposed method not only eliminates the need for manual labor but also achieves remarkable enhancements, improving the mAP by 4.1% and the F1-score by 4.5%.
