DANGER DEGREE CALCULATION DEVICE, CONTROL DEVICE FOR UNMANNED DOLLY, AND METHOD THEREFOR

To provide a recovery technique for tracking an object highly accurately compared with a conventional technique.SOLUTION: A danger degree calculation device includes: detection means that, in an environment where a worker and an unmanned dolly move, detects respective positions of the worker and the unmanned dolly; and calculation means by which a degree of danger that may be caused on the worker by the unmanned dolly is calculated with reference to an environment map including a travelable route for the unmanned dolly in the environment and based on a distance between the worker and the unmanned dolly along the travelable route.SELECTED DRAWING: Figure 6 【課題】従来よりも精度の良い物体追跡の回復技術を提供する。【解決手段】作業員および無人搬送車が移動する環境における前記作業員および前記無人搬送車の位置を検出する検出手段と、前記環境において前記無人搬送車の走行可能経路を含む環境地図を参照して、前記走行可能経路に沿った前記作業員と前記無人搬送車の間の距離に基づいて、前記無人搬送車が前記作業員に与える危険度を算出する算出手段と、を備える、危険度算出装置。【選択図】図６
