Abstract:With the acceleration of urbanization, the scale and quantity of housing construction projects continue to grow, which puts forward higher requirements for the accuracy, efficiency and comprehensiveness of engineering detection. Traditional detection methods gradually expose the inherent shortcomings of low efficiency and limited precision when dealing with complex structures and large-scale projects. The rise of intelligent technology provides a new technical path for building engineering inspection. This paper deeply discusses the innovative application of intelligent technology in engineering detection, and systematically analyzes the application principle, technical advantages and typical cases of UAV detection technology, intelligent sensor monitoring system, big data and cloud computing analysis technology, aiming to provide theoretical support and practical reference for improving the detection level of housing construction projects and ensuring the construction quality and safety.
