stereo-mideval 1.0.11

Evaluation dataset and tools from Middlebury Stereo Evaulation data 2014.

stereo-mideval

Python package for dataset and evaluation tools from the Middlebury stereo evaulation 2014 dataset. This project is in development by I3DR for evaluating stereo matching algorithms for use in stereo cameras. However, this project is fully open-source with no limitations to encorage and support others who may need this.

Install

pip install stereo-mideval

Features

• Download scene data from Middlebury servers
• Load disparity image and stereo pair from scene data
• Display normalised colormaped disparity image
• Convert disparity image to depth image using calibration file from scene data

Examples

Download and display data from all scenes in Middlebury stereo dataset (2014)

import os
from stereomideval import Dataset

# Path to dowmload datasets
DATASET_FOLDER = os.path.join(os.getcwd(),"datasets")

# Create dataset folder
if not os.path.exists(DATASET_FOLDER):
    os.makedirs(DATASET_FOLDER)

# Initalise stereomideval Dataset object
stmid_dataset = Dataset()

# Get list of scene in dataset (2014) and iterate through them
for scenename in stmid_dataset.get_scene_list():
    # Download dataset from middlebury servers
    # will only download it if it hasn't already been downloaded
    print("Downloading data for scene '"+scenename+"'...")
    stmid_dataset.download_scene_data(scenename,DATASET_FOLDER)
    # Load scene data from downloaded folder
    print("Loading data for scene '"+scenename+"'...")
    scene_data = stmid_dataset.load_scene_data(scenename,DATASET_FOLDER,True)

Download and display data from a single scene in Middlebury stereo dataset (2014)

import os
from stereomideval import Dataset

# Path to dowmload datasets
DATASET_FOLDER = os.path.join(os.getcwd(),"datasets")
# Scene name (see here for list of scenes: https://vision.middlebury.edu/stereo/data/scenes2014/)
SCENE_NAME = "Adirondack"

# Create dataset folder
if not os.path.exists(DATASET_FOLDER):
    os.makedirs(DATASET_FOLDER)

# Initalise stereomideval Dataset object
stmid_dataset = Dataset()

# Download dataset from middlebury servers
# will only download it if it hasn't already been downloaded
print("Downloading data for scene '"+SCENE_NAME+"'...")
stmid_dataset.download_scene_data(SCENE_NAME,DATASET_FOLDER)
# Load scene data from downloaded folder
print("Loading data for scene '"+SCENE_NAME+"'...")
stmid_dataset.load_scene_data(SCENE_NAME,DATASET_FOLDER,True,0)

Developement

Upcomming features

• Evaluation of disparity image compared to ground truth disparity
• Evaulation of depth image compared to ground truth depth for real-world error metrics
