Embodiment 1
[0031] Embodiment 1 of the present invention proposes a method for generating a high-resolution depth map, such as figure 1 shown, including:
[0032] Step S1: collecting a low-resolution depth map and a first low-resolution brightness map of the same scene, where the size of the first low-resolution brightness map and the low-resolution depth map are the same.
[0033] In Embodiment 1 of the present invention, the existing depth image sensor can be used to realize the collection of the low-resolution depth map and the first low-resolution brightness map. For example, the Microsoft kinect depth image sensor can be used to simultaneously collect the same scene with the same size A low-resolution depth map and a first low-resolution luminance map.
[0034] Step S2: Perform up-sampling processing on the low-resolution depth map to obtain a high-resolution rough depth map, calculate the image contour in the high-resolution rough depth map, and obtain a contour map corresponding t...
Embodiment 2
[0064] Embodiment 2 of the present invention proposes a system for generating a high-resolution depth map, such as Figure 5 As shown, for ease of description, only the part related to Embodiment 2 of the present invention is shown.
[0065] In detail, the system for generating a high-resolution depth map proposed in Embodiment 2 of the present invention includes: an image acquisition module 1, configured to acquire a low-resolution depth map and a first low-resolution brightness map of the same scene, and the first low-resolution The size of the high-resolution brightness map is consistent with the size of the low-resolution depth map; the first image processing module 2 is used to perform up-sampling processing on the low-resolution depth map to obtain a high-resolution rough depth map, and calculate the high-resolution rough depth map. Image contour, obtain the contour map corresponding to the high-resolution rough depth map, the size of the high-resolution rough depth map ...
Embodiment 3
[0073] Embodiment 3 of the present invention proposes a computing device, including the system for generating a high-resolution depth map as described in Embodiment 2 above, which will not be repeated here.
[0074] In summary, the method and system for generating a high-resolution depth map proposed by the present invention is to convert the low-resolution depth map into a high-resolution rough depth map by using an upsampling algorithm, and then further obtain the high-resolution rough depth map The contour map of the contour map, and then use the low-resolution brightness map to find the block that is most similar to each overlapping contour block in the contour map in the low-resolution depth map, and then use the weighted splicing method to fill the found blocks. Input the corresponding position of the high-resolution coarse depth map to obtain the high-resolution depth map. Compared with the existing technology, after the high-resolution rough depth map is obtained, the ...
