# ArUCo-Markers-Pose-Estimation-Generation-Python This repository contains all the code you need to generate an ArucoTag, detect ArucoTags in images and videos, and then use the detected tags to estimate the pose of the object. In addition to this, I have also included the code required to obtain the calibration matrix for your camera. <img src = 'Images/pose_output_image.png' width=400 height=400> ## 1. ArUCo Marker Generation The file `generate_aruco_tags.py` contains the code for ArUCo Marker Generation. You need to specify the type of marker you want to generate. The command for running is :- `python generate_aruco_tags.py --id 24 --type DICT_5X5_100 --output tags/` You can find more details on other parameters using `python generate_aruco_tags.py --help` ## 2. ArUCo Marker Detection The files `detect_aruco_images.py` and `detect_aruco_video.py` contains the code for detecting ArUCo Markers in images and videos respectively. You need to specify the path to the image or video file and the type of marker you want to detect. The command for running is :- **For inference on images** `python detect_aruco_images.py --image Images/test_image_1.png --type DICT_5X5_100` **For inference using webcam feed** `python detect_aruco_video.py --type DICT_5X5_100 --camera True ` **For inference using video file** `python detect_aruco_video.py --type DICT_5X5_100 --camera False --video test_video.mp4` You can find more details on other parameters using `python detect_aruco_images.py --help` and `python detect_aruco_video.py --help` ## 3. Calibration The file `calibration.py` contains the code necessary for calibrating your camera. This step has several pre-requisites. You need to have a folder containing a set of checkerboard images taken using your camera. Make sure that these checkerboard images are of different poses and orientation. You need to provide the path to this directory and the size of the square in metres. You can also change the shape of the checkerboard pattern using the parameters given. Make sure this matches with your checkerboard pattern. This code will generate two numpy files `calibration_matrix.npy` and `distortion_coefficients.npy`. These files are required to execute the next step that involves pose estimation. Note that the calibration and distortion numpy files given in my repository is obtained specifically for my camera and might not work well for yours. The command for running is :- `python calibration.py --dir calibration_checkerboard/ --square_size 0.024` You can find more details on other parameters using `python calibration.py --help` ## 4. Pose Estimation The file `pose_estimation.py` contains the code that performs pose estimation after detecting the ArUCo markers. This is done in real-time for each frame obtained from the web-cam feed. You need to specify the path to the camera calibration matrix and distortion coefficients obtained from the previous step as well as the type for ArUCo marker you want to detect. Note that this code could be easily modified to perform pose estimation on images and video files. The command for running is :- `python pose_estimation.py --K_Matrix calibration_matrix.npy --D_Coeff distortion_coefficients.npy --type DICT_5X5_100` You can find more details on other parameters using `python pose_estimation.py --help` ## Output <img src ='Images/output_sample.png' width = 400> <img src ="Images/pose_output.gif" width="500" height="400"> ### <ins>Notes</ins> The `utils.py` contains the ArUCo Markers dictionary and the other utility function to display the detected markers.
