Self-driving vehicles have been using light detection and ranging technology (LiDAR) to map their surroundings. Lidar is a way of determining distance by analyzing the time a shooting laser takes from a sensor. However, technology keeps advancing daily, leading to the invention of advanced LiDAR products.
4D LiDAR is the most recent and advanced technology adopted in automated vehicles. The 4D LiDAR sensor uses Frequency Modulated Continuous Wave (FMCW) technology. It directly detects the instant velocity of each point, in addition to a precise 3D position at long range.
Characteristics of LiDAR that Make it a Most Recommended
Below are the characteristics associated with 4D LiDAR technology from LiDAR Technology company.
Long range performance
This technology is immune to blooming and ghosting from retroreflectors. Using 4D LiDAR on automated machines enhances its perception when viewing reflective objects. It can detect an object up to 500 m away.
The technology detects common and highly reflective objects in the sensor’s field of view. These objects may include towers, safety vests, or adhesive tapes. This makes it easy to identify small objects on the road with confidence.
Ultra resolution
It has a camera-level resolution. It provides up to 20 times the resolution of legacy LiDAR sensors. It delivers high-resolution images with up to 1000 lines per frame. More so, it contains no motion blur from data captured in real-time.
Image segmentation enables the detection of driving regions, road markings, road barriers, and vegetation. It allows the detection of road hazards at up to twice the distance of conventional sensors. This aspect makes it efficient, safe, and reliable for the end user.
Instant velocity detection
The technology perceives the exact location of an object. Moreover, it can precisely tell the velocity of a moving object. It directly determines the velocity for each point of detection. This helps in determining whether an object is moving or stationary.
It can measure the instantaneous velocity for each pixel. This allows the vehicle to recognize the speed and location of an object within 500 m.
Automotive grade
The 4D LiDAR is manufactured to withstand harsh climatic elements. This ensures peak performance under any environmental condition across various autonomous applications. Regardless of the season, this technology is reliable and safe.
Aeries ii has no risk of interference from other sources on the road. These distractors include lights from passing vehicles or other LiDAR systems used by other vehicles. Aeries ii is designed to meet the requirements of ISO 16750 standards.
Compact and versatile
This technology is compact and designed for maximum versatility. It is 75% smaller than the previous generation. It integrates all key sensor components onto silicon photonics in a compact module. These key sensors include optics, receivers, and transmitters.
