[Objective] The aim was to explore the measurement of coordinate parameter by multi-baseline digital close-range photogrammetry system. [Method] The 3-dimensional coordinate of 8-year-old Jujube was measured by using Lensphoto multi-baseline digital close-range photogrammetry system, and through comparing with measured data of Total Station, the error and accuracy of photogrammetry data were analyzed.[Result] The absolute error of X, Y and Z coordinate was 0 - 0.014, 0 - 0.018 and 0 - 0.004 m respectively, and the relative error of X, Y and Z coordinate was less than 0.145%. The significance test of pairs for the photogrammetry data and measured data of Total Station indicated that the space coordinate data of stumpage were accurately measured by using the multi-baseline digital close-range photogrammetry method, and the photogrammetry data meet the need of space coordinate measurement for virtual plant growth simulation. [Conclusion] This study had provided theoretical basis for the growth measurement of virtual plant growth simulation.
