我有一個校準立體相機設定，每個相機都有 11 個 DLT 系數（使用
使用 DLT 三角測量獲得拋物線軌跡（圖已旋轉以與重力對齊）
However, when I convert the DLT coefficients into a Projection matrix (P, where x = P X, where x is the 2d pixel coordinates, P is a 3x4 matrix and X is a homogenous 4x1 matrix with object 3d coordinates included) - the 'shape' of the trajectory makes sense but the values don't (values close to ~0.01 for x,y,z).
Obtained trajectory using Projection matrix based method cv2.triangulatePoints(plot has been rotated to align with gravity)
Can anyone please explain why the Projection matrix based method produces oddly scaled coordinates or what is being done wrong here?
The discrepancy doesn't make sense as the DLT coefficients and projection matrix are inter-convertible (e.g. see
