Covering Mainstream AI Application Scenarios
In specific applications, MEGVII classifies deep learning algorithms into three categories: sensing, actuating and optimization. The company is dedicated to achieving cognition and decision-making from human faces, the environment, and various other objects. These core algorithms have been applied and implemented in MEGVII’s business scenarios in varying degrees.
Control and Optimization Technologies in Robotics
Collaborative Optimization Technologies in Robotics
  • Face/Body/Vehicle/Object Detection
    Detect and locate subjects including human faces,human bodies, vehicles and various other general objects within images and videos and return high-precision object bounding boxes.
  • Face/Body/Vehicle/Object Comparison
    Check the likelihood that two subjects belong to the same person or that two objects are the same and generate a confidence score to measure the similarity.
  • Dense Facial Landmarks
    Accurately locate and generate hundreds of landmarks of facial features, including face contour, eye, eyebrow, lip and nose contour.
  • Face Attributes
    Analyze a series of face related attributes including age, gender, smile intensity, head pose, eye status, emotion, beauty, eye gaze, mouth status, skin status, image quality and blurriness.
  • Emotion Recognition
    Analyze and identify emotion of detected faces. Analysis result of each detected face includes confidence scores for several kinds of emotions.
  • Object Instances/Scene Segmentation
    Separate object instances or semantic regions from the background within images and videos and return high-precision object/region boundaries.
  • Gesture/Action Recognition
    Detect and recognize hand/body gestures and human actions and generate high-precision confidence score.
  • Large Scale Photo Clustering and Search
    Recognize objects in a large scale photo collection and automatically group the photos of the same object or instance together for easy photo search.
Control and Optimization Technologies in Robotics
  • Depth and Landmark Sensing
    This technology uses a pair of cameras or a pair of camera and projector or a single camera, to compute depth or locate landmarks of environment where the robot is, or the object to be manipulated.The depth or landmarks is computed by a deep learning method which directly learns the sensing capabilities from a large amount of training examples.
  • Deep SLAM (Simultaneous Localization and Mapping)
    This technology is the process of creating a map using a robot that navigates that environment while using the map it generates. In the localization, deep learning global visual features are used for robustness and deep learning local visual features are applied for accuracy. In the mapping, the whole system integrates multiple inputs to construct the map in real-time.
  • 6D Object Detection and Pose Estimation
    This technology detects and estimates 6D pose (3D location + 3D orientation) of objects to be gripped or manipulated. Taking both camera input and depth sensing, accurate object pose is obtained by an end-to-end learned estimator which is offline trained on various objects and pose variations.
  • Motion Planning
    This technology finds a sequence of movements or valid configurations that moves a robot or a robotic arm from the source state to destination state. In both planning tasks, we use an efficient sampling-based approach to obtain a fast and reliable initial solution and keep improve the planning strategy by a reinforcement learning approach which can learn from experiences and improve performance over time.
Collaborative Optimization Technologies in Robotics
  • Multi-robot Traffic Scheduling
    This technology provides a unified traffic command system, allowing multiple mobile robots to move in an orderly manner in a unified area, avoiding congestion and optimizing the traffic efficiency of the entire robot group.
  • Job Scheduling & Resource Load Balance
    Optimize the load balance for various resources (goods, shelves, etc.) through batching and scheduling of different tasks, to improve the overall task completion efficiency.
  • Storage Optimization
    Use operational research algorithms to optimize the storage and storage area of the goods and improve the latency and throughput of our overall operation.
  • Global Orchestration
    Dynamically configures the overall operating rhythm and various optimizations based on current robot status, item status, order status and order forecasts.
