A multi-node data synchronous acquisition system and a method for real-time monitoring of underwater surface deformation. The system includes at least four sensor arrays, where each of the sensor array consists of a plurality of ribbon-like rigid substrates connected by movable joints. On each section of rigid substrate, three sensor units are respectively connected to a slave station data acquisition unit through cables. The slave station data acquisition unit is connected with a central controller through a cable. The central controller includes a compressive cabin outside and an embedded controller and a power supply inside. Each slave station data acquisition unit acquires data from an MEMS attitude sensor and then transmits it to the embedded controller. The present invention may realize synchronous acquisition of underwater or even underwater multi-node data, implement three-dimensional surface reconstruction, and may be used for improving the ocean observation capability.
