GROUND SURVEY DEVICE, GROUND SURVEY SYSTEM, GROUND SURVEY PROGRAM, AND GROUND SURVEY METHOD

PROBLEM TO BE SOLVED: To provide a ground survey device, a ground survey system, a ground survey program and a ground survey method capable of quickly and automatically surveying a correct altitude value of the ground only with a heavy machine travelling on the ground.SOLUTION: There is provided a ground survey device 1 installed on a heavy machine 10, for surveying the ground. The heavy machine 10 comprises a three-dimensional surveying apparatus 11 for surveying a three-dimensional coordinate of a reference position in the heavy machine 10, an inclination sensor 12 for detecting inclination data showing the attitude of the heavy machine 10 and a ground distance meter 13 set at the rear side of the heavy machine 10, for measuring a ground distance to a ground surveying point on the ground. On the basis of a relative position obtained by defining, as a base point, the reference position of the ground surveying point specified by the three-dimensional coordinate of the reference position, the inclination data and the ground distance, the heavy machine has a ground surveying point acquisition unit 54 for acquiring a three-dimensional coordinate of the ground surveying point.SELECTED DRAWING: Figure 1 【課題】重機で地盤上を走行するだけで、地盤の正確な標高値を迅速かつ自動的に測量することができる地盤測量装置、地盤測量システム、地盤測量プログラムおよび地盤測量方法を提供する。【解決手段】重機１０に設けられて地盤を測量する地盤測量装置１であって、重機１０には、重機１０における基準位置の３次元座標を測量するための３次元測量機器１１と、重機１０の姿勢を表す傾斜データを検出する傾斜センサ１２と、重機１０の後方に設定された地盤上の地盤測量点までの地盤距離を計測する地盤距離計１３とが備えられており、基準位置の３次元座標、傾斜データ、および地盤距離によって特定される地盤測量点の基準位置を基点とする相対位置に基づいて、地盤測量点の３次元座標を取得する地盤測量点取得部５４を有する。【選択図】 図１
