Embodiment 1
[0053] The panoramic depth image acquisition method in this embodiment starts with the characteristics of the optical power value changing with time during the dynamic change process of the liquid crystal lens, and screens out the corresponding depth of field range according to the corresponding relationship between the optical power value and the depth of field range during the dynamic change process of the liquid crystal lens. The optical power value whose depth of field range can cover the entire imaging space is used as the target optical power value. Then find out the specific moment when the liquid crystal lens is at the target focal power value according to the characteristics of the power value changing with time, and finally collect a small amount of images at the specific time found above as the image for subsequent depth-of-field stitching. Since the image acquisition time in this embodiment is determined according to the depth-of-field requirement that the depth-of-...
Embodiment 2
[0115] This embodiment provides a method for synthesizing a depth-of-view image, in which a depth-of-field image is obtained by performing depth-of-field fusion processing on an image collected by using the method for collecting a depth-of-view image in Embodiment 1.
[0116] The depth of field fusion processing method here adopts the wavelet fusion algorithm, and of course other algorithms can also be used. The specific method is to perform wavelet decomposition on the collected original image according to the principle of wavelet transform, and perform one-dimensional filtering on all the rows and columns of the extracted sub-image. Compare the maximum value of the wavelet decomposition coefficient in a series of images, and perform wavelet reconstruction through inverse transformation to synthesize a full depth image. The specific process can be to first carry out N-level wavelet decomposition on each collected image to obtain its high-frequency sub-image and low-frequency ...
