-# image-matcher
+# Image-Matcher
 
-Add-on for Blender that allows matching multiple 2D images to a corresponding 3D model. This uses OpenCV's Perspective-n-Point solver to estimate camera intrinsics (e.g. focal length, distortion coefficients) and extrinsics (camera position and orientation) based on pairs of 2D and 3D points.
+## A Blender Add-on for 2D-3D Image Matching and Camera Pose Estimation
 
-This add-on builds on RT Studio's Camera Pnpoint Blender plugin: 
+Image-Matcher is a Blender add-on that allows matching multiple 2D images to a corresponding 3D model. This tool uses OpenCV's Perspective-n-Point solver to estimate camera intrinsics (e.g., focal length, distortion coefficients) and extrinsics (camera position and orientation) based on pairs of 2D and 3D points.
+
+This project is a fork of [K-Meech's image-matcher](https://github.com/K-Meech/image-matcher), with improvements made by the Center for Spatial Technologies (CST) team. We extend our sincere gratitude to the original developers and contributors for their excellent work.
+
+Originally builds on RT Studio's Camera Pnpoint Blender plugin: 
 https://rtstudios.gumroad.com/l/camera_pnpoint / https://github.com/RT-studios/camera-pnpoint
 Do consider buying their addon on gumroad/blender market to help support them making great Blender addons!
 
-This plugin adds:
-- Easier matching of multiple 2D images
-- Point mode to allow one click addition of 2D/3D points
-- UI to visualise list of points for each image
-- Easier adjustment of camera parameters / background image directly in the plugin UI
-- Export of camera parameters to JSON
+## Key Features and Improvements
 
-For more information on the Perspective-n-Point process, see OpenCV's documentation: https://docs.opencv.org/4.x/d5/d1f/calib3d_solvePnP.html
+Our fork builds upon the original plugin with several enhancements:
+
+1. **Enhanced Animation Support**: Improved functionality for creating smooth camera animations between matched positions.
+2. **Frame-by-Frame Solving**: Added capability to solve camera pose for each frame in a sequence.
+3. **Keyframe Management**: New features to update camera poses for existing keyframes.
 
 ## Installation + Tutorials
 
 - There's a full video tutorial of installation + image matching on youtube: https://www.youtube.com/watch?v=3gHtWkfxcvo
 - For installation instructions, see: [Installation](./docs/installation.md)
 - For a step by step tutorial of image matching, see: [Image matching tutorial](./docs/image-matching.md)
-- For a tutorial of making a video moving between each matched position, see: [Video tutorial](./docs/video.md). Note: this tutorial is advanced, and assumes prior Blender experience!

-## Examples
 
-You can see an example video moving between matched positions here: https://www.youtube.com/watch?v=zqXh3yGqvkA This uses publicly available data of the Ramesses II statue from the British Museum (data from [Sketchfab](https://sketchfab.com/3d-models/ramesses-ii-c98e1cab68134f4283f0448966f0835b) and [Collection Online](https://www.britishmuseum.org/collection/object/Y_EA19))

-## Releases
+We welcome contributions to further improve this tool. Please submit issues or pull requests through GitHub.
 
-Github Actions runs on this repository to automatically create releases when a
-commit is pushed to main with a version tag like v1.0.0. This will automatically
-create a zip file with only the required python files for installation in Blender.
+---
 
-To trigger this:
-```
-# Add a tag to last commit (on main)
-git tag v1.0.0
-git push origin --tags
-```
