An underwater photographing technique is widely applied to fields such as underwater target reconnaissance/detection/recognition and submarine resource exploration. According to the existing underwater imaging technique, an underwater image is acquired by fixedly providing a camera at the bottom of the sea. The fixed camera cannot be moved and has a small visual range. According to the towed underwater image acquisition apparatus provided in the invention, a camera can be towed, a position sensor is further provided, and a photosensitive sensor is provided at the bottom of the water, so as to achieve photographing requirements. |
