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.

Aeries ii compactness saves space due to its small size and weight. Aeries ii integrated Aeva’s unique LIDAR-on-chip technology. It increases the safety and performance of the installed autonomous vehicle. The lidar-in-chip design eliminates all fiber optics in its operation.

4D localization

This technology does not need additional sensors like GPS. Instantaneous velocity data enables real-time vehicle motion estimation with 6 degrees of freedom. This makes autonomous navigation in featureless environments possible.

4D perception technology gives up to 20 times the resolution of legacy sensors.  LiDAR technology company affirmed this.

The 4D LiDAR specs that Make it Stand out

The key features of this technology are instant velocity detection, LiDAR-on-chip, and a compact design. It has a camera level ultra-resolution and ultra-long range of up to 500 m.

Below are additional specifications of this LiDAR technology;

  • Instant velocity detection
  • 4D localization
  • Road hazard detection
  • Multiple FOVS

Why Most People are Choosing 4D LiDAR Technology

Vehicles are becoming increasingly automated each day. Next-generation sensor technology such as 4D LiDAR makes them safe and reliable. It can confidently detect small objects on the roadway up to 500 m.

Its invention is a great boost in the autonomous vehicles world. Its positive impacts in the industry outshine its cons. Automated vehicles using this technology can perceive low and reflectivity targets without edge effects.

Conclusion

LiDAR technology is dedicated to improving your road experience. The 4D LiDAR is extremely sensitive, safe, and efficient. With this technology, sight-related accidents will significantly go down making the roads a safe place by a significant percentage.
