In order to solving the problem of the multiple bullet target matching and multiple bullet three-dimensional trajectory calculation., this article proposes a method for bullet three-dimensional trajectory measurement based on an adaptive multiple target surface and multiple iteration algorithm. In this method, it set up a virtual cuboids target space which includes multiple bullet trajectories. It used two high speed cameras, one in left and another in right, to capture images. In the vertical direction of the bullet flying, these images were segmented into infinite plane, which are multiple target surfaces. It used the projective transformation to recover the target two-dimensional image from the left and the right images, and repeated this process until finding the bullet point in left view is coincide with that in right view. If the points were found, it indicated that it achieves the goal's accurately matching and every space location of the bullet. The simulation experimental results show that this method is feasible, image processing and analysis is merely influenced by background. This method can effectively realize the bullet three-dimensional trajectory target matching, and it has strong maneuverability.
