I cite a product below which is emploied as terrain following and height fixing for drones.

DE LiDAR TF01, a product widely known in the drone and smart devices industries, was an immediate success upon its appearance at the show. Its application in altitude measurement, drone terrain following, distance measurement and security sensors were particularly attractive to visitors from all over the world.

The module, already in mass production, can work with flight controllers like Pixhawk and TopXGun andaddresses the difficulty of altitude measurement that many drone and flight controller producers experienced. Unlike traditional altitude measurement solutions such as GPS, barometers and ultrasound, the module can detect and refresh the distance between a flying drone and crops on the ground in real time at a frequency of 500 times per second. It also ensures that the drone can fly at a stable height with an error in centimeters. The module, which is free from the interference of temperature, ambient light change and airflow, can also significantly improve the work performance of drones.

During the show, TF01 was synchronously launched for sale on global hardware platforms likeSeeed (https://www.seeedstudio.com/) and RobotShop (https://www.robotshop.com/) and dozens ofdistributors kick off business talks with Benewake.

Benewake began to deploy a patenting strategy overseas for its LiDAR product as early as 2014. By far, it has built an independent intellectual property system (through overseas patents) and passed a complete range of European and American product certification (FCC, CE, etc.), which ensures the legitimate use and sale of the product internationally.

@opticsly I am interested in replacing my ultrasonic sensors for a Lidar but the TF01 only seems to have a 10m range. The LIDAR-Lite 3 though claims a 40m range and is $20 less expensive at the robotshop.com. 

As I known, TF01 is design to drone's height fixing, specially, instead of a general distance detecting device.

  • It works well under 100 klux sunlight  outdoors. It is protected from the dust, water, and corrosion.
  • It fits differenct ground suface: plant, grass, raod, mud,
  • Comparing the shape, TF01 is like a mass production product with integrated design.

I got the response from Benewake's FAE

"There are some significant differences between our TF01 and other laser options (such as lightware or lidarlite):
1. The product TF01 has a complete system, containing a protective shell made of materials with a high transmittance of infrared, which doesn't affect the optical performance.
2. The product TF 01 has been widely used in the height fixing and the terrain following of the drone, especially in the agriculture. As a considerably mature product in the market, our TF01 has collected a large amount of experience and actual data in different situations, which has been taken as feedback for further improvements of the product itself. Meanwhile to guarantee the reliability of the TF01, we conducted a rigorous seismic test and the performance of TF01 turned out excellent
