Visual Positioning and Enhancement SDK
Visual positioning is different from GPS positioning. By collecting camera and other sensor data and performing deep fusion, six degrees of freedom pose information with more information dimensions (including three-dimensional position information and orientation information) can be returned, which can cover the accurate positioning of some indoor or outdoor scenes and support the accurate superposition display of virtual content

Function introduction
3D reconstruction of high-precision map
By analyzing and processing the scene video data collected by users, build a high-precision 3D map of the scene and store it in the cloud, providing users with high-precision positioning capabilities and visual reference models when designing virtual reality fusion scenes
Accurate spatial positioning
Based on the constructed 3D visual map and accurate positioning algorithm, the user can return six degrees of freedom position and pose information by using the images obtained in real time in the real scene, thus achieving continuous and accurate positioning based on visual space
Virtual reality fusion and superposition
Put the virtual content to the specified position in the high-precision 3D map, and combine the six degrees of freedom pose returned from the SDK to accurately stack and fuse the virtual information in the real physical world through rendering
Product architecture
Product composition and use process
Rely on visual positioning service platform（ https://vpas.beta-ar.com/ ）Visual positioning and enhancement products are composed of SDK, offline data processing services and online positioning map services. We will provide users with relevant products and supporting services. The product use process includes several stages such as data collection, offline data processing, SDK integration and AR content development, online location map service, and online project testing
data acquisition
Users create projects on the visual positioning service platform, and use the collection hardware and tools we recommend to collect and submit data according to the requirements of the data collection scheme
Offline data processing
Process the data submitted by users, and feed back the reference model and data quality feedback that can place AR content to users through the visual positioning service platform
SDK integration and AR content development
Users complete the integration of visual positioning and enhanced SDK in their own applications, and develop and bind AR content based on the reference model that can place AR content
Positioning map service online
After the user completes the content development, notify Baidu to launch the positioning map service
Project testing goes online
After the location map service goes online, users can call the map for testing, and the project goes online after the test is completed
Application scenarios
Indoor and outdoor navigation
Enhancement of scenic spot recovery
Smart Sand Table
Industrial patrol inspection
Indoor and outdoor navigation
Through the application of visual positioning, the problem of GPS signal attenuation and poor stability in indoor/outdoor environment can be remedied, which can help users to lock the spatial position of the target and accurately stack virtual content. Combined with the map path planning ability, it can easily realize the navigation and navigation of indoor positioning scenes
