Abstract EN
Synthetic aperture imaging (SAI) technology gets the light field information of the scene through the camera array.
With the large virtual aperture, it can effectively acquire the information of the partially occluded object in the scene, and then we can focus on the arbitrary target plane corresponding to the reference perspective through the refocus algorithm.
Meanwhile, objects that deviate from the plane will be blurred to varying degrees.
However, when the object to be reconstructed in the scene is occluded by the complex foreground, the optical field information of the target cannot be effectively detected due to the limitation of the linear array.
In order to deal with these problems, this paper proposes a nonlinear SAI method.
This method can obtain the occluded object’s light field information reliably by using the nonlinear array.
Experiments are designed for the nonlinear SAI, and refocusing is performed for the occluded objects with different camera arrays, different depths, and different distribution intervals.
The results demonstrate that the method proposed in this paper is advanced than the traditional SAI method based on linear array.
