Visual Simultaneous Localization and mapping is a process that determines the orientation and position of a sensor as far its surroundings are concerned. At the same time, it performs the mapping of the environment around the sensor. As far as commercialization is concerned, this technology is still in its period of infancy. The good thing is that it claims to address the shortcomings of navigation and vision systems. Let’s find out more about the benefits and applications of this system.
First of all, it is important to remember that SLAM is not the name of a specific piece of software or algorithm. As a matter of fact, it represents the process that determines the orientation and position of a sensor.
SLAM technology is of various types. Many of them don’t use a camera but refers to a system that taps into the power of 3D vision in order to perform mapping and location functions. You can find this technology in different forms. However, the overall concept is the same in all systems.
How visual SLAM Technology Works
In most visual SLAM systems, the tracking of set points is done through camera frames. The purpose is to triangulate the 3D position. At the same time, it uses the given information in order to get approximate repose from the camera.
Primarily, the goal of the systems is to perform the mapping of the surroundings with respect to the location for easy navigation. It can be done through one 3D vision camera. If enough points are tracked, it is possible to track the sensor orientation and the physical environment around it.
New alarm systems can help reduce reproduction errors with the help of an algorithm known as bundle adjustment. Basically, these systems work in real-time. Therefore, both mapping data and education data go through bundle adjustment at the same time. This helps boost processing speeds prior to their ultimate merger.
Applications that use Visual SLAM
In the near future, SLAM will become an important component of augmented reality. With SLAM, an accurate projection of virtual images requires precision-based mapping of the physical environment. Therefore, virtual SLAM technology can provide the accuracy of this level.
The good thing is that these systems are deployed in a lot of field robots, such as rovers and lenders that are used to explore Mars. They are used in order to control the way your SLAM systems work for autonomous navigation.
Similarly, this technology is used in drones and field robots. Autonomous vehicles can use the systems in order to map and understand the world around them. In the future, SLAM systems can take the place of GPS navigation and tracking. The reason is that these systems offer much better accuracy than GPS.
Long story short, this was an introduction to the benefits and applications of the Visual SLAM technology. I hope that this article will help you get a deeper understanding of the system.
