LiDAR and Robot Navigation
LiDAR is one of the central capabilities needed for mobile robots to navigate safely. It comes with a range of capabilities, including obstacle detection and route planning.
2D lidar scans the environment in one plane, which is easier and more affordable than 3D systems. This creates a powerful system that can identify objects even when they aren't perfectly aligned with the sensor plane.
LiDAR Device
LiDAR (Light Detection and Ranging) sensors employ eye-safe laser beams to "see" the world around them. These sensors calculate distances by sending out pulses of light and analyzing the amount of time it takes for each pulse to return. The data is then processed to create a 3D, real-time representation of the region being surveyed called"point clouds" "point cloud".
LiDAR's precise sensing ability gives robots a thorough understanding of their environment, giving them the confidence to navigate different situations. The technology is particularly good at determining precise locations by comparing the data with maps that exist.
lidar sensor robot vacuum devices vary depending on their application in terms of frequency (maximum range), resolution and horizontal field of vision. But the principle is the same across all models: the sensor transmits a laser pulse that hits the environment around it and then returns to the sensor. This is repeated thousands of times every second, leading to an enormous number of points that represent the area that is surveyed.
Each return point is unique, based on the composition of the surface object reflecting the light. Buildings and trees for instance have different reflectance levels as compared to the earth's surface or water. The intensity of light also differs based on the distance between pulses and the scan angle.
The data is then processed to create a three-dimensional representation. an image of a point cloud. This can be viewed by an onboard computer for navigational purposes. The point cloud can be filterable so that only the area that is desired is displayed.
The point cloud may also be rendered in color by matching reflect light to transmitted light. This allows for a better visual interpretation as well as a more accurate spatial analysis. The point cloud can also be labeled with GPS information that provides precise time-referencing and temporal synchronization which is useful for quality control and time-sensitive analyses.
LiDAR is utilized in a myriad of industries and applications. It can be found on drones used for topographic mapping and for forestry work, and on autonomous vehicles to make an electronic map of their surroundings to ensure safe navigation. It can also be used to determine the vertical structure of forests, which helps researchers assess carbon sequestration and biomass. Other applications include environmental monitors and monitoring changes to atmospheric components like CO2 and greenhouse gases.
Range Measurement Sensor
The heart of LiDAR devices is a range sensor that continuously emits a laser signal towards surfaces and objects. This pulse is reflected and the distance to the surface or object can be determined by measuring the time it takes the laser pulse to be able to reach the object before returning to the sensor (or reverse). Sensors are mounted on rotating platforms to enable rapid 360-degree sweeps. Two-dimensional data sets give a clear view of the robot vacuum lidar's surroundings.
There are a variety of range sensors and they have varying minimum and maximum ranges, resolution and field of view. KEYENCE has a range of sensors and can help you choose the best lidar vacuum one for your needs.
Range data can be used to create contour maps in two dimensions of the operating area. It can be used in conjunction with other sensors like cameras or vision systems to increase the efficiency and robustness.
Cameras can provide additional visual data to assist in the interpretation of range data, and also improve the accuracy of navigation. Some vision systems are designed to use range data as input to a computer generated model of the environment that can be used to direct the robot based on what it sees.
It's important to understand the way a LiDAR sensor functions and what it is able to accomplish. The robot can move between two rows of plants and the objective is to identify the correct one by using the LiDAR data.
