The MEMS (Microelectromechanical Systems) technology is a new interesting research direction which aims to manufacture and assembly of micro-systems. The research of micro assembly robot has. significances of academy and commerce. In the paper the theory and related key technologies of micro-assembly robot based on computer microscope vision feedback were investigated To enlarge the manipulation area. a novel method of microscope focusing automatically was studied. The focusing process was carried out in cursory step and accurate one. The coarse focusing was based oil the image My histogram while the accurate one compared the width of image edges. Theory analysis and experiments showed that this algorithm enlarged the microscope focusing depth, with the advantages of simplicity and good real time performance.
In this paper we introduce a new approach to adaptive stereoscopic vision. We use genetic programming, where the input to the individuals is raw pixel data from stereo image-pairs acquired by two CCD cameras. The outp...

As development and productization of complex technology for new markets is challenging, it is crucial to get valid information about the intended future users and represent that information in a proper way to technical experts and project management. This case study describes experiences from using the "engaging personas and narrative scenarios" approach [1], [2] for defining requirements for next-generation industrial robots. We found that additional steps were necessary to supplement the methodology to fit the development of complex industrial robots, namely globalization, validation of personas among end users, prioritization of personas, creation of common vocabulary, identification of business critical scenarios and identification of safety critical situations. The main benefit from using personas and scenarios was their role as communication catalyst and how the descriptions facilitate building a common vision within the project team.

3D multi-object tracking (MOT) is a key problem for autonomous vehicles, required to perform well-informed motion planning in dynamic environments. Particularly for densely occupied scenes, associating tracks to new detections remains challenging as existing systems tend to omit critical contextual information. Our proposed solution, InterTrack, introduces the Interaction Transformer for 3D MOT to generate discriminative object representations for data association. We extract state and shape features for each track and detection, and efficiently aggregate global information via attention. We then perform a learned regression on each track/detection feature pair to estimate affinities, and use a robust two-stage data association and track management approach to produce the final tracks. We validate our approach on the nuScenes 3D MOT benchmark, where we observe significant improvements, particularly on classes with small physical sizes and clustered objects. As of submission, InterTrack ranks 1st in overall AMOTA among methods using CenterPoint [1] detections.

stereo matching is a core task for many computervision and robotics applications. Despite their dominance in traditional stereo methods, the hand-crafted Markov Random Field (MRF) models lack sufficient modeling accuracy compared to end-to-end deep models. While deep learning representations have greatly improved the unary terms of the MRF models, the overall accuracy is still severely limited by the hand-crafted pairwise terms and message passing. To address these issues, we propose a neural MRF model, where both potential functions and message passing are designed using data-driven neural networks. Our fully data-driven model is built on the foundation of variational inference theory, to prevent convergence issues and retain stereo MRF's graph inductive bias. To make the inference tractable and scale well to high-resolution images, we also propose a Disparity Proposal Network (DPN) to adaptively prune the search space of disparity. The proposed approach ranks 1st on both KITTI 2012 and 2015 leaderboards among all published methods while running faster than 100 ms. This approach significantly outperforms prior global methods, e.g., lowering D1 metric by more than 50% on KITTI 2015. In addition, our method exhibits strong cross-domain generalization and can recover sharp edges. The codes at https://***/aeolusguan/NMRF.
