Abstract

In this paper, an object recognition method and a pose estimation approach using stereo vision is presented. The proposed approach was used for position based visual servoing of a 6 DoF manipulator. The object detection and recognition method was designed with the purpose of increasing robustness. A RGB color-based object descriptor and an online correction method is proposed for object detection and recognition. Pose was estimated by using the depth information derived from stereo vision camera and an SVD based method. Transformation between the desired pose and object pose was calculated and later used for position based visual servoing. Experiments were carried out to verify the proposed approach for object recognition. The stereo camera was also tested to see whether the depth accuracy is adequate. The proposed object recognition method is invariant to scale, orientation and lighting condition which increases the level of robustness. The accuracy of stereo vision camera can reach 1 mm. The accuracy is adequate for tasks such as grasping and manipulation.

The intended future application is of one satellite observing another, when flying in close formation. The ideas explored in this article build on methods developed in camera calibration and Kaiman

Abstract

This paper describes a method for the detection of textureless objects. Our target objects include furniture and home appliances, which have no rich textural features or characteristic shapes. Focusing on the ease of application, we define a model that represents objects in terms of three-dimensional edgels and surfaces. Object detection is performed by superimposing input data on the model. A two-stage algorithm is applied to bring out object poses. Surfaces are used to extract candidates fromthe input data, and edgels are then used to identify the pose of a target object using two-dimensional template matching. Experiments using four real furniture and home appliances were performed to show the feasibility of the proposed method.We suggest the possible applicability in occlusion and clutter conditions.

MARKER REMOVAL FOR C-ARM POSE ESTIMATION BASED BRONCHOSCOPE NAVIGATION USING IMAGE INPAINTING Teena Steger1, Sebastian Steger1 and Stefan Wesarg1 1Medical Computing, Fraunhofer IGD, Darmstadt, Germany teena.steger@igd.fraunhofer.de Abstract: Using marker-based C-arm pose estimation dur- ing bronchoscopy in combination with a preoperative CT segmentation of the bronchial tree, the 3D spatial position of the bronchoscope tip inside the airways can be deter- mined. Naturally, the markers used for pose estimation ap- pear on the fluoroscopy images, which can be

-wearable technologies. As PD is more prominent in elderly people, wearable sensors may hinder the natural persons movement and is considered out of scope of this paper. Non-wearable technologies especially Image Processing (IP) approaches captures data of the person’s gait through optic sensors Existing IP approaches which perform gait analysis is restricted with the parameters such as angle of view, background and occlusions due to objects or due to own body movements. Till date there exists no researcher in terms of analyzing gait through 3D pose estimation. As deep

integrated, the line of sight problem is minimized and the QR code markers are intuitively in the field of view of the camera. A special feature is that QR codes of different sizes can be flexibly used for various instruments since the QR code size, that is required to determine the position, and transformation from marker to tip can be stored in the QR code. A further benefit of using a QR code as a marker for pose estimation, is that the QR code structure allows to detect many feature points that can be used for precise detection.
