A Passive Ranging Algorithm Based on Imaging Detection
It investigated in an algorithm for passive ranging algorithm based on the targets image information along with direction information.It aimed at to avoid the sick solution of the quadratic equation for distance estimation, such as the complex solution, or the negative solution, a novel one variable quadratic equation is proposed for distance estimation.In our method, the distance ratio between two sampling times could be obtained from image matching based on feature points, and combined both the space coordinate of the observer itself and direction cosine parameters of the target to the observer, a passive distance ranging equation is settled.Theoretical analysis shows that when the observer with non-zero displacement in the adjacent sampling times, this passive ranging equation could always be solvable.It illustrated by our reduced mode experiment that the proposed algorithm is simple and feasible, Telative ranging error is smaller than the former quadratic equation.It confirmed that under the same observation model, if the observer itself is moving, the distance estimation would be in much simpler mathematical form.
