What is VPS (Visual Positioning System)? (original) (raw)
Last Updated : 24 Feb, 2023
Visual Positioning System (VPS) is a technology that uses computer vision and machine learning algorithms to determine the location and orientation of a device or vehicle in the physical world. It works by comparing the images captured by the device's camera with a database of pre-mapped images and using machine learning techniques to estimate the device's position and orientation based on the similarities and differences between the captured images and the pre-mapped images.
What is VPS?
Visual Positioning System (VPS) is a new generation of GPS systems that use satellite signals to pinpoint the receiver's location on Earth. VPS can be used for various applications, including indoor and outdoor navigation, augmented reality, and autonomous vehicle localization. It is beneficial in situations where GPS signals are weak or unavailable, such as indoors or in urban canyons.
- VPS can be used with other positioning technologies, such as GPS, to provide a more accurate and reliable estimate of the device's position and orientation.
- It can also be used as a standalone technology in cases where GPS signals are not needed or unavailable.
- It uses phone cameras and Google's extensive back-end data to analyze the surroundings to identify the location with great accuracy.
- It uses signals from several satellites thus helping to overcome inaccuracies.
- It is more accurate in urban areas where GPS signals can be blocked by large objects.
How Does VPS Work?
Visual Positioning System (VPS) is a technology that uses computer vision and machine learning algorithms to determine the location and orientation of a device or vehicle in the physical world. It works by comparing the images captured by the device's camera with a database of pre-mapped images and using machine learning techniques to estimate the device's position and orientation based on the similarities and differences between the captured images and the pre-mapped images.
Here is a general overview of how VPS works:
- The device captures images of the surrounding environment using its camera.
- These images are compared to a database of pre-mapped images using machine learning algorithms.
- The VPS system determines the device's location and orientation by analyzing the similarities and differences between the captured images and the pre-mapped images.
- The device's position and orientation are then used to provide location-based services, such as indoor or outdoor navigation, augmented reality, or autonomous vehicle localization.
VPS can be used in combination with other positioning technologies, such as GPS, to provide a more accurate and reliable estimate of the device's position and orientation. It can also be used as a standalone technology in cases where GPS signals are not needed or not available.
Indoor VPS
Indoor Visual Positioning System (VPS) is a technology that uses computer vision and machine learning algorithms to determine the location and orientation of a device or vehicle within an indoor environment. It is similar to traditional GPS but is designed to work in environments where satellite signals are not available or are less accurate, such as within buildings or urban canyons.
Indoor VPS has a wide range of potential applications, including:
- Navigation: Indoor VPS can be used to guide users to their destination within a building, such as a shopping mall or airport. It can provide precise location information and directions and can be used to enhance the accuracy and reliability of location-based services such as ride-hailing and delivery.
- Asset Tracking: Indoor VPS can be used to track the movement of people or assets within a facility, such as a warehouse or a hospital, to improve efficiency and productivity. It can also enhance security and safety by providing real-time location information for emergency responders or other personnel.
- Robotics: Indoor VPS can enable robots to navigate and interact with their surroundings in a more natural and intuitive way, improving the precision and accuracy of robotic tasks.
- Virtual and Augmented Reality: Indoor VPS can be used to create immersive and interactive training experiences for a variety of industries, such as healthcare, manufacturing, and the military. It can enhance the effectiveness and efficiency of training by providing a realistic and interactive learning environment.

It can also enhance the safety and reliability of industrial processes by providing real-time location and orientation information.
VPS vs GPS
Global Positioning System (GPS) is a satellite-based navigation system that uses signals from a network of orbiting satellites to determine the location and time of a receiver on or near the Earth's surface. GPS is widely used for a variety of applications, including navigation, tracking, surveying, and scientific research.
