For each camera that have been estimated by the Structure-From-Motion, it estimates the depth value per pixel.
|
|
|
|
Adjust the downscale factor to compute depth maps at a higher/lower resolution.
|
|
Use a downscale factor of one (full-resolution) only if the quality of the input images is really high (camera on a tripod with high-quality optics).
