abstract = {Pipeline inspection robots are commonly used to detect cracks and structural defects inside industrial pipelines. In low-cost embedded systems, deep-learning models can create high computational load and unstable detection outputs, reducing both efficiency and reliability. This work evaluates a Raspberry Pi based vision inspection robot and applies two deployment-level optimizations: INT8 quantization of a baseline FP32 YOLO model and multi-frame confidence confirmation. Quantization reduces inference latency and CPU usage, while temporal confirmation reduces false positives caused by single-frame instability. Results from controlled experiments show substantial runtime improvement with minor confidence reduction and improved detection stability during continuous inspection. The combined method provides a practical balance between efficiency and reliability for low-cost embedded pipeline inspection.},
