in the fvcmm proposed in this paper, a special designed rectangular grid mark is required to be attached to the surface of the object . the grid nodes on the surface are treated as measurement marks . the 3-dimensional coordinates of these grid nodes are calculated through processing the grid images which captured by four cameras 本論文提出的基于網格標記的四目視覺坐標測量系統的模型首先需要在被測量物體上覆蓋一層特殊的網格,把網格點作為測量特征點來處理,通過對帶有網格標記的圖象對的處理、計算,得到網格點的三維坐標。
after systematic researches on computer vision coordinate measurement techniques, this paper proposed a four-eyed vision coordinate measurement model ( fvcmm ) based on rectangular grid mark . a four-eyed vision coordinate measurement system ( fvcms ) was constructed based on this model . it was firstly applied to strain measurement during the process of metal plate deformation and gained some success 本論文對視覺坐標測量技術進行了系統的研究,建立了一個基于網格標記的四目視覺坐標測量系統的模型,并基于這一模型研制了一臺四目視覺坐標測量儀,這一儀器用于金屬板料變形過程的應變測量,得到了較好的效果。
