Hi to all I have gathered experience with Imagine Photogrammetry software processing Stereo Pleiades block (few models) for photogrammetric products (dsm, ortho')
for the rest activities (segmentation, classification ...) I use OTB application... My Question is - can we do the photogrammetric steps (1 - Block adjustment, 2- DSM, 3- Rectification) with OTB as well ? The answer should be yes - However when I go over the cookbook (e.g in 4.2.5 residual registration, 5.7 stereo), I do not see the first step - model triangulation - where we compute external orientation for the each images based on ground control and tie points (to enhance the model external / internal geometry and to set the local projection). 1 - I need to match between the images and ortho (GCP points) - I will use existing ortho' for that, 2 - I need to match between the two images to have the best stereo model (tie points) *Is the following workflow is the right direction ?* for step 1 - match between each image & existing ortho (for GCP) using otbcli_HomologousPointsExtraction - then use otbcli_RefineSensorModel for each image for step 2 - match between two stereo images (for TIE) using otbcli_HomologousPointsExtraction - then use otbcli_RefineSensorModel for each image step 1 - GCP - can be done manually because the few number of points - I cannot see where to input the external GCP list... then I will be able to continue and to extract DSM using Stereo Framework BR.
