Full textMy Ph. D manuscript deals with the problem of markerless human motion capture. We propose an approach that relies on the use of multiple cameras and that avoids most of the constraints on the environment and the use of markers to perform the motion capture, as it is generally the case for industrial systems. The absence of markers makes harder the problem of extracting relevant information from images but also to correlate this information between. Moreover, interpreting this extracted information in terms of joint parameters motion is not an easy task. We propose an approach that relies on occluding contours of the human body. We studied the link between motion parameters and the apparent motion of the edges in images. Minimizing the error between the extracted edges and the projection of the 3D model onto the images allows to estimate the motion parameters of the actor. Among the opened issues, we show that using video based motion capture allows to provide additional hints such as contacts between body parts or between the actor and its environment. This information is particularly relevant for improving character animation

Full textHow optimal are human movements ? This thesis tackles this issue by focusing especially on climbing movements, studied here under three complementary aspects which are the experimental gathering of climbing sequences, the biomechanical analysis of these data, and the synthesis of gestures by timing optimization. Walking has been largely studied, with good results in animation [Mordatch 2013]. We are interested here especially in the original question of climbing motions, whose diversity and multicontact aspect present an interesting complexity for the evaluation of the human motion characteristics. The heterogeneity of climbing gestures can be linked to several factors which are the variety of wall shapes, the multiplicity of climber skill levels, and different climbing categories, namely bouldering, route climbing or speed climbing. Our exploratory approach of this sport consists in three steps: the data collection by multicamera marker-based motion capture, combined with a set of force sensors mounted on an in-laboratory bouldering wall; a gesture analysis by inverse dynamics, taking only kinematic data as inputs, based on the minimization of internal torques to resolve the multicontact ambiguity, intrinsic to the climbing activity, validated by comparison with sensor measurements; and finally, the use of the energy efficiency criterion for synthesizing the best timing associated with a given sequence of movements. Experimental recordings were made at McGill University which has a climbing wall instrumented of 6 force sensors, and a motion capture device of 24 cameras, which allowed us to collect data on a population of nine subjects. The analysis of these data is the second part of this thesis. The addressed challenge is to find the external forces and internal torques from the climber's movements only. To this end we assume an optimal distribution of internal torques. After analysis, the distribution turns out to be rather uniform than proportional to the muscle capacity associated to each body joint. Finally, in a third and last part, we focus on the timing of climbing gestures, taking as input the path of the climber, possibly after inverse kinematics in order to overcome the need for a capture with markers and infrared cameras. As output, an optimal timing for this path is found. This timing is realistic, but lacks of a modelization for hesitation and decision making instants, as well as a model for the contact establishment, with the associated temporal delay currently not taken into account

Full textMany motion capture systems emerge each year. However, although these systems are part of the family of metrology tools, the information on measurement accuracy is heterogeneous and their scope is at the discretion of the user. In this context, the research question I asked myself was : how to compare the accuracy of motion capture systems of different technologies and how to define a compatible application ? In this thesis, I was interested in optical motion analysis systems with markers. The two motion capture systems I used are the Mokam system (Kinestesia ,Verton, France) and the Vicon system (Oxford Metrics, United Kingdom). The latter is considered as the reference. In order to obtain the precision information of a system, I proposed an experimental protocol to evaluate the precision in statics and during the realisation of movement. Then I identified applications for postural control or quantified analysis of the locomotion achievable by a system according to its precision capabilities. This research work aloud, in a first step, to evaluate the spatial precision of three-dimensional localisation of these two systems transposable to all marker-based motion capture systems. Secondly, it was shown that measurement accuracy is a crucial point in determining the application of these systems. In other words, not every motion capture system can be dedicated to every application

Full textVideo-based markerless motion capture has benefitted, in the last few years, from the development of automatic point estimation methods, which are based on deep learning techniques. For motion analysis in biomechanics, these methods have numerous advantages, such as the possibility to analyse the movement without participant-worn equipment or outside of the laboratory. The goal of this thesis is thus to contribute to the evaluation and development of video-based markerless motion capture methods for applications in biomechanics. First, an existing video-based markerless motion capture method is evaluated for movements and kinematic parameters, rarely studied in the literature. Then, 2D keypoints estimated by automatic point estimation methods are characterized, and the influence of these characteristics on 3D point reconstruction is studied. Finally, a method using whole confidence heatmaps – which are obtained using automatic point estimation methods – to compute 3D kinematics is proposed and evaluated

Full textThe human hand is a prehensile organ which allows people to handle objects with various sizes and shapes. It is wonderful tool that can be used to perform different simple or complex tasks with strength or great dexterity. It is also a crucial tool in the daily life, both at home and in the workspace, and loss of hand functionality may quickly become disabling for some people. There are few studies in the literature. However, motion capture and kinematic analysis of the hand is becoming more and more of an interest in different areas such as medicine, ergonomics, sport, robotics, virtual reality and video games. Results from these studies have improved knowledge about skills of the hand and how to preserve them. The studies have also improved interactions between people and computers in order to command robots or to progress in virtual reality. The aim of the thesis was to develop methods for an in vivo and subject-specific kinematic analysis in order to contribute to the improvement of knowledge about the human hand motion. A first part of this thesis was to develop a protocol for the motion capture of the hand for male and female subjects aged from 20 to 50 years old. The motion capture was performed using an optoelectronic system with passive markers glued on the skin of the hand. Two sorts of movements were captured. Firstly, functional movements like flexion-extension and abduction-adduction. Secondly, prehensile movements of cylindrical and spherical objects. Then, markers on the motion captures were identified in order to extract their trajectories. The second part of this thesis consisted in the development of a method for the kinematic analysis of external hand movements from the marker trajectories. Validation of this method was achieved using a model of the hand developed in silico. Since no noise was added to the marker trajectories in the silico model; kinematic parameters were estimated with precision. Moreover, assessment of the functional methods showed that the hand motions can be approximated by a plane, a circular arc or a spherical cap depending on the joint studied. After constructing the functional coordinate systems for each segment of the hand using the joint kinematic parameters, it was possible to decompose any joint rotation into three Cardan angles. This decomposition method was validated using the marker trajectories of the hand model, except for the trapeziometacarpal (TMC) and the metacarpophalangeal (MCP1) joints of the thumb which are more difficult to study. The last part of this thesis consisted in the analysis of the functional and the prehensile movements from the motion captures. The curves of the Cardan angles obtained from the functional movements are similar to those presented in the literature for all of the joints, except for the TMC joint. It was also noticed that the joint rotations do not occur around only one axis, but around one dominant axis and one or two secondary axes. However, some differences between the curves of the Cardan angles around the secondary axes obtained in this thesis and those presented in the literature were noticed for some joints. Despite only few prehensile grasps were analyzed, some interesting correlations were also found between the hand shape and the objects grasped, more particularly at the metacarpophalangeal (MCP) and the distal interphalangeal (DIP) joints

Full textThis thesis deals with motion capture (MoCap) which goal is to acquire the attitude of human's body. In our case, the arm and the leg are considered. The MoCap trackers are made of "software" and "hardware" parts which allow acquisition of the movement of an object or a human in space in real or differed time. Many MoCaps systems still exist, but they require an adaptation of the environment. In this thesis, a low cost, low weight attitude central unit (UCN namely a triaxes magnetometer and a triaxes accelerometer), is used. This attitude central unit has been developed within the CEA-LETI. In this work, we propose different algorithms to estimate the attitude and the linear accelerations of a rigid body. For the rotation parametrization, the unit quaternion is used. Firstly, the estimation of the attitude and the accelerations (6DDL case) from the measurements provided by ACU is done via an optimization technique. The motion capture of articulated chains (arm and leg) is also studied with ad-hoc assumptions on the accelerations in the pivot connections, the orientation of the segments as well as the accelerations in particular points of the segments can be estimated. The different approaches proposed in this work have been evaluated with simulated data and real data

Full textThe simulation of human movement is an active theme of research, particularly in ergonomic analysis to aid in the design of workstations. The aim of this thesis concerns the automatic generation of reaching tasks in the horizontal plane for a virtual humanoid. An objective expressed in the task space, requires coordination of all joints of the mannequin. The main difficulties encountered in the simulation of realistic movements is related to the natural redundancy of the human. Our approach is focused mainly on two aspects: - Motion of the hand's operator in the task space (spatial and temporal aspect), - Coordination of all kinematic chains. To characterize human movement, we conducted a set of motion capture with position and orientation constraints of the hand in the horizontal plane. These acquisitions allowed to know the spatial and temporal evolution of the hand in the task space, for translation and rotation aspects. These acquired data were coupled with a playback method to analyze the intrinsic relations that link the task space to joint space of the model. The automatic generation scheme of realistic motion is based on a stack of task with a kinematic approach. The assumption used to simulate the action is to follow the shortest path in the task space while limiting the cost in the joint space. The scheme is characterized by a set of parameters. A global map of parameter adjustment enables the simulation of a class of realistic movements. Finally, this scheme is validated quantitatively and qualitatively with comparison between the simulation and the human gesture
