  • Photo-realistic recoloring of 3D point clouds:
    Here is a first result in order to cover a heritage building as the Amiens cathedral for coloring a preliminary 3D model (point cloud) with a high definition. To do so, photos are registered over point clouds got from laser scanners by implementing a pose direct computation.

  • 3D model based pose estimation exploiting mutual information:
    This work was made during my postdoc, from october 2010 to august 2011, in the Lagadic team of INRIA Rennes/IRISA. It focused on the achievement of a new method of model-based pose estimation using non-linear optimization. The pose is optimized maximizing the mutual information shared by a real image of a video/camera stream and the synthetic image obtained as the projection of the textured 3D model. The mutual information similarity criterion between images, being highly robust to various visual perturbations, has been developed in the PhD thesis of Amaury Dame for visual servoing, 2D plane tracking and introduced the mutual information based pose estimation (3D tracking).

HAUT3D model-based tracking for omnidirectional stereovision

This is a result of calculating the pose using stereo omnidirectional sensor. This time, the information used is richer because it uses a 3D model composed of faces, edges and vertices to calculate the pose of the camera. This type of work was carried out in monocular omnidirectional vision by the Lagadic research team. We extended it to omnidirectional stereovision. Here is a video of tracking and pose computation of a box:

HAUTPoints-based pose estimation and calibration

  • In November 2008, I made a stay in the Lagadic team from IRISA/INRIA in Rennes and I worked with Eric Marchand. During this stay, I worked in the calibration and sensor pose calculation with a monocular omnidirectional sensor and then with the omnidirectional stereovision sensor. Here is a video for each case.
    The monocular pose computation was applied to the 3D external localization of a mobile robot. We consider a fisheye camera and equip the mobile robot with a target made of four infrared LEDs. The target pose, and hence the one of the robot, is then computed from these points. La pose de la balise, et donc celle du robot, est ensuite calculée à partir de ces points. This video shows the experimental setup and localization results:
    This video can also be downloaded.

  • Then, in 2009, I generalized the calibration to hybrid stereo rigs with Damien Eynard, particularly combining a perspective camera and a fisheye, the first modelled by the so called pinhole model and the other by the central unified projection model of Geyer/Barreto. The method allows to calibrate N cameras with N different models, intrinsically and extrinsically, simultaneously. Since then, we also integrated the ah hoc projection model of the paracatadioptric camera.

    Software design

    HySCaS : Hybrid Stereoscopic Calibration Software

    This software is the implementation of the simultaneous intrinsic and extrinsic stereo calibration method that I proposed during my PhD thesis. This software has been developed with Damien Eynard. Stereo rigs with different camera models are calibrated by this cross-platform software (Linux, Mac, Windows) and developed in C++ with Qt, ViSP and OpenCV library.
    HySCaS is available from the software section of this website.
