A plurality of sensors is utilized for continuously sensing a plurality of relative distances between a surface of an object and the plurality of sensors within a predetermined space, and is utilized for generating a plurality of distance data according to the plurality of relative distances. A data processing module is utilized for establishing an outline model of the object according to the plurality of distance data. Therefore, resolution of the outline model generated by measuring an outline of the object can be significantly increased.複數個感測器在一預定空間範圍內,連續感測之一物體的表面與複數個感測器之複數個相對距離,並根據複數個相對距離產生複數個距離資料。資料處理模組用來根據複數個感測器所產生之複數個距離資料,建立物體之外型曲線模型。如此一來,可大幅提升量測物體外型時所產生之外型曲線模型的精確度。100...物體外型量測系統102、104、106、108、110、112...感測器150...載體160...資料處理模組R1、R2...偵測範圍RA...有效偵測範圍
