Abstract: Sewer network is related to the public safety and environmental protection. The defect detection of sewer has received more attention. CCTV is a technology widely used in the sewer defect detection. Motivated by the success of the CNN (Convolutional Neural Network) in the image recognition, this paper proposes a CNN-based sewer defect detection to improve the intelligence and automation of the CCTV technology. Experimental results show that the proposed method is effective and the accuracy, recall and run-time meet the requirements of the sewer defect detection. Moreover, this method has been widely used in the city of Shenzhen.

Key words: Convolutional neural network, Sewer detection, CCTV endoscopic detection, automation, intelligence
