Visual representations are chosen to meet the requirements of specified tasks such as object recognition or stereoscopic matching. Related to symmetry based representations that have been used in pattern and object recognition, its structure is determined , not heuristically but precisely, by the nature of the grasping task. Its value is demonstrated by its incorporation into the control of robotthat can manipulate objects under visual guidance.

the program Tobject planning the movement of the Adept Six-300 robot is presented in this work. Location of the manipulation object, observed by the two cameras Edimax IC-7100P, is calculated by this program. the program is one of the most important components of the computer intelligence of this robot. the method of determining the geometric parameters occurring in the equations of the kinematics of the gripper and manipulation object was presented. the program Tobject geometric calibrates of cameras using an algorithm that does not rely on the calculation of the projection matrix or the fundamental matrix. therefore, these algorithms are faster and more accurate than the algorithms that use the projection matrix and the fundamental matrix. On the basis images of the manipulation object, obtained by these two cameras, the program Tobject calculates the trajectory of the gripper movement to this object. In discretization point of the trajectory this program calculates coordinates the joint variables of the manipulator. In the calculations, multiple solutions of inverse kinematics are taken into account, including solutions in singular configurations. Among these the multiple solutions is a chosen solution minimizing the square indicator of quality. the program Tobject is installed in the server that cooperates withrobot controller and cameras, by Ethernet net.

this paper focuses on describing an implementation for an Ackermann-type vision-based Automated Guided Vehicle (AGV) used for the transportation of materials between and within industrial facilities. this implementation was done using a ZED Stereo Camera, robot Operating System (ROS), ORB-SLAM2, and Unitronics PLCs and MCUs. the solution proposes a self-localization within a map previously created driving the vehicle around the desired route, the following of such route, and stopping along whenever the operator designated that the vehicle should stop. the vehicle can follow and mimic the route in environments with controlled lighting conditions

Autonomous mobile transport systems are a crucial part of flexible factory logistics enabling a highly-adaptable industrial production organization. Edge computing bares the potential to support commissioning and operation of these mobile robots through offloading computation in a very flexible and scalable manner. Among these benefits, less onboard computation means also less energy consumption and longer operation durations. In order to evaluate the specific effects of offloading computing following the Software as a Service principle, we consider different software service distribution scenarios in terms of real-time critical navigation as well as additional computervision functions. We present an empirically study using and assessing 4G radio networks in order to realize distributed control scenarios within industrial environments. the software services are offloaded to the edge following a modern microservice approach. Our results show that onboard computing can be covered by a low-cost single-board computer and energy consumption can be reduced by 4.9% to 18.4% through offloading computation depending on the payload and average velocity. Regarding to additional computervision algorithms, the energy savings are even higher.

In this paper we present a framework for path planning and path finding for multiple mobile robots with global vision. Our framework model considers the agents' dynamic status and their environment with obstacles to perform given tasks. the global vision system provides feedback to main controller computer and mobile robots are directed towards to their tasks with avoiding obstacles and without any collision. Different kinds of scenario are prepared to simulate manipulating tasks and non-collision behavior with our framework. Experiment results with Lego Mindstorms NXT shows that our framework can be used where a multi robot system is needed with minimum resources.

Pose determination of 3D object with respect to a camera is an important problem in computervision. Straight line is one feature which exists widely in natural environments. In this paper, a new pose determination method from four straight line correspondences is presented. this algorithm is simple to solve and has good real-time characteristic. Furthermore, unique solution for object pose can be obtained. At last, simulation results show this method is reasonable and has good real-time characteristic.

Machine vision is a technology that uses image processing and analysis techniques to acquire and understand image information, enabling the recognition, measurement, and detection of objects. Machine vision is widely used in aerospace manufacturing for automated production, quality inspection, and robot guidance. It can improve the efficiency and quality of aerospace manufacturing, reduce labor costs and risks, promote innovation and optimization, adapt to various inspection needs, and realize intelligent, automated, and digital manufacturing processes. this paper introduces the types of vision technologies, overviews the typical applications of machine vision for quality inspection in aerospace manufacturing, (including component surface inspection, drilling quality inspection, assembly quality inspection, and gluing quality inspection), analyzes the advantages, challenges, and development trends of machine vision for quality inspection in aerospace manufacturing, and looks forward to future research directions to support further research and application.

this paper concerns 3D object recognition from vision. In our robotics context an object must be recognized and localized in order to be grasped by a mobile robot equipped with a manipulator arm: several cameras are mounted on this robot, on a static mast or on the wrist of the arm. the use of such a robot for object recognition, makes possible active strategies for object recognition. this system must be able to place the sensor in different positions around the object in order to learn discriminant features on every object to be recognized in a first step, and then to recognize these objects before a grasping task. Our method exploits the Mutual Information to actively acquire visual data until the recognition, like it was proposed in works presented in (Denzler and Brown, 2000) and (Denzler et al., 2001): color histogram, shape context, shape signature, Harris or Sift points descriptors are learnt from different viewpoint around every object in order to make the system more robust and efficient.

this paper records the research and procedures of developing a smart mobility robot with detection system to collect rubbish. the objective of this paper is to design a mobile robotthat can detect and recognize medium-size rubbish such as drinking cans. Besides that, the objective is also to design a mobile robot withthe ability to estimate the position of rubbish from the robot. In addition, the mobile robot is also able to approach the rubbish based on position of rubbish. this paper explained about the types of image processing, detection and recognition methods and image filters. this project implements RGB subtraction method as the prior system. Other than that, algorithm for distance measurement based on image plane is implemented in this project. this project is limited to use computer webcam as the sensor. Secondly, the robot is only able to approach the nearest rubbish in the same views of camera vision and any rubbish that contain RGB colour components on its body.
