<p>PROBLEM TO BE SOLVED: To provide an underground search apparatus which can simply arrange in order data obtained from a plurality of searches with a travelling position while shifting position. SOLUTION: This underground search apparatus includes a search track 1, having a plurality of underground radar sensors 2a arranged in a breadthwise direction of a vehicle or an underground radar sensor 2a arranged movably in the breadthwise direction, an image-processing means loaded to the search track for obtaining two-dimensional or three-dimensional image information on the basis of information from the underground radar sensor 2a, and a road face image-pickup means 3 for picking up the image of a road surface, where the search track 1 runs with a wider breadth than a search breadth of the underground radar sensor and recording travelling information. Search information for a plurality of lanes can be combines with reference to the picked-up information of the road face image-pickup means 3.</p> |
