PDF from images. Script downscales all jpg images and then merges them into pdfs with pdftk.
#!/usr/bin/python3.5
import os
import glob
import pathlib
from pathlib import Path
# How to use:
# Run in directory with folders named from 1 and up to 99. Each folder should contain *.JPG files.
# Script will downscale all files that are not yet downscaled to "downscaled" subdirectory and stitch to multiple pdfs: pdf per folder + single full pdf.
# Example of input directories:

OpenCV compilation script for python bundled with PhotoScan. Should work with any other Python (and with virtualenv). Tested on Ubuntu 16.04
# Configure path to photoscan:
PHOTOSCAN_PATH=<.../photoscan-pro>
PYTHON_PATH=${PHOTOSCAN_PATH}/python
OPENCV_VERSION=3.4.0
INSTALLATION_PATH=/opt/opencv-${OPENCV_VERSION}
sudo mkdir -p ${INSTALLATION_PATH}
# Install numpy (OpenCV requires it)
CPPFLAGS=-I${PYTHON_PATH}/include/python3.5m LDFLAGS=-L${PYTHON_PATH}/lib ${PYTHON_PATH}/bin/python3.5 -m pip install numpy==1.08
