LIDARs have become indispensable tools today, thanks to massive technological advancement. A lidar sensor may be fitted on an autonomous car to enhance obstacle detection and reduce road accidents.
Choosing the right lidar sensor can sometimes be tricky since they have varying resolutions and obstacle detection capabilities. For instance, some lidar sensors can only detect an object at close range, while others have enhanced long-range capabilities.
Read on to understand how a lidar sensor works on automated vehicles. Plus, we’ll highlight the top features of Aeries ΙΙ, the world’s first 4D LiDAR sensor.
What Is LiDAR?
LiDAR is an acronym for “Light Detection and Ranging.” The system uses light waves to determine the distance between objects.
Typically, LiDAR sensors emit light waves that can travel to a nearby object and back. Once the light wave returns, the sensor determines the time the wave takes to revert. The sensor then uses the recorded time to measure the distance between the sensor and an object.
The sensor can send multiple pulses in seconds targeting different objects along its path. As a result, the sensor automatically creates a model of different features within the surrounding.
Features of the Aeries ΙΙ 4D Sensor
The Aeries ΙΙ is the first sensor of its kind, capable of detecting objects as far as 500 meters away. Besides long-range distance tracking, it has subtle features that make it stand out from its predecessors.
Some top features of the 4D sensor include;
Camera Level Resolution
Aeries ΙΙ’s resolution is superb, thanks to a built-in 4D Perception Software. The sensor achieves up to 20 times the resolution of other LiDAR sensors. Therefore, your vehicle can detect an obstacle even at high speeds when driving.
Velocity and Position Estimation
The 4D lidar sensor can accurately determine your velocity, only allowing a tiny error margin. You can also determine your current position without a GPS or additional sensor.
Gives Instant Velocity Data
The system gives precise velocity data from other vehicles using the road. Thus, you can confidently detect oncoming traffic and pedestrians up to 500 meters away.
Detects the Smallest Objects
LiDAR sensors can detect the tiniest objects, such as tire fragments that aren’t visible at high speeds. And what’s more, it detects smaller fragments at twice the distance that other sensors require.
Has a Smaller Design
Unlike its predecessors, the 4D LiDAR sensor has a sleek, compact design. The benefit of a smaller design is its ability to accommodate different sensor points.
Can Withstand Shock and Impact
The ultra-modern sensor was designed to withstand various harsh ratings. Therefore, you don’t need to worry about impact, extreme shock, or vibrations as you drive.
Can Withstand Intense Sunlight
The sensor uses Frequency Modulated Continuous Wave (FMCW) technology to enhance its endurance. It can withstand intense sun rays, especially when driving in the scorching sun. In addition, its performance remains at its peak even with other lighting conditions.
4D LiDAR comes in a silicon chip that reduces the need for fiber. Instead, it gathers all LiDAR sensing elements in one compact chip for easy production. If demand for the product increases, mass production of more units is not an issue.
