* At `Google <http://www.google.com>`_, Ceres is used to:

  * Estimate the pose of `Street View`_ cars, aircrafts, and satellites.
  * Build 3D models for `PhotoTours`_.
  * Estimate satellite image sensor characteristics.
  * Stitch `panoramas`_ on Android and iOS.
  * Apply `Lens Blur`_ on Android.
  * Solve `bundle adjustment`_ and `SLAM`_ problems in `Project
    Tango`_.

* `Willow Garage`_ uses Ceres to solve `SLAM`_ problems.
* `Southwest Research Institute <http://www.swri.org/>`_ uses Ceres for
  `calibrating robot-camera systems`_.
* `Blender <http://www.blender.org>`_ uses Ceres for `planar
  tracking`_ and `bundle adjustment`_.
* `OpenMVG <http://imagine.enpc.fr/~moulonp/openMVG/>`_ an open source
  multi-view geometry library uses Ceres for `bundle adjustment`_.
* `Microsoft Research <http://research.microsoft.com/en-us/>`_ uses
  Ceres for nonlinear optimization of objectives involving subdivision
  surfaces under `skinned control meshes`_.
* `Matterport <http://www.matterport.com>`_, uses Ceres for global
  alignment of 3D point clouds and for pose graph optimization.
* `Obvious Engineering <http://obviousengine.com/>`_ uses Ceres for
  bundle adjustment for their 3D photography app `Seene
  <http://seene.co/>`_.
* The `Autonomous Systems Lab <http://www.asl.ethz.ch/>`_ at ETH
  Zurich uses Ceres for

  * Camera and Camera/IMU Calibration.
  * Large scale optimization of visual, inertial, gps and
    wheel-odometry data for long term autonomy.

* `OpenPTrack <http://openptrack.org/>`_ uses Ceres for camera
  calibration.
* The `Intelligent Autonomous System Lab <http://robotics.dei.unipd.it/>`_
  at University of Padova, Italy, uses Ceres for

  * Camera/depth sensors network calibration.
  * Depth sensor distortion map estimation.

* `Theia <http://cs.ucsb.edu/~cmsweeney/theia>`_ is an open source
  Structure from Motion library that uses Ceres for `bundle adjustment`_
  and camera pose estimation.

* The `Applied Research Laboratory <https://www.arl.psu.edu/>`_ at
  Pennsylvania State University uses in their synthetic aperture Sonar
  beamforming engine, called ASASIN , for estimating platform
  kinematics.

* `Colmap <https://github.com/colmap/colmap>`_ is a an open source
  structure from motion library that makes heavy use of Ceres for
  bundle adjustment with support for many camera models and for other
  non-linear least-squares problems (relative, absolute pose
  refinement, etc.).
