TFA170-L Height Measuring Long-range High Precision Lightweight Single-point Laser Radar Sensor for Vehicle/UAV Drones

TFA170-L Height Measuring Long-range High Precision Lightweight Single-point Laser Radar Sensor for Vehicle/UAV Drones

Description:
- TFA170-L is a long-range high-precision lightweight single-point LiDAR. Its multiple built-in operating modes allow customers to adjust parameters and configurations to meet various applications.
- It's a globally leading lightweight LiDAR product with a range of over 170 meters. With a reduction of 1 gram enhancing flight time by approximately 6 seconds, it can significantly increase the operation time of drones.
- Compact design: 31 x 30.2 x 19.2mm. The LiDAR's special reflective optical path design gives it an exceptionally small size among similar products, making it ideal for integration into compact drone airframe and tight gimbal.
- Under the flight control firmware for PX4, Ardupilot, iNaV, and BetaFlight platforms, the following flight control hardware is supported: for Pixhawk1, CUAV Series, Pixhawk Cube Series, Beagle Bone Blue, Pixhawk Flight Controllers from Holybro, and Drotek Pixhawk3.
- Compatible with multiple platforms: for PX4 partners, Ardupilot partners.

For Drone Delivery:
Achieved functions:
- Fixed altitude flight
- Assisted Landing

Advantages:
- Accurate identification of small targets such as express cabinets.
- LiDAR has low power consumption, small size, and light weight, making it a perfect match for unmanned aerial vehicle customers who are highly sensitive to such parameters.
- High precision at close range, suitable for unmanned aerial vehicles that require high stability landing.
- There are specialized algorithm optimizations for measuring black and white high contrast targets (such as QR codes).

For Drone Inspection:
Achieved function:
- Dotting distance measurement: measuring the distance of points of interest in the image.
- Coordinate calculation: calculate the coordinates of the target object based on the angle of IMU and the distance of LiDAR.
- Fixed distance shooting: shooting a target object at a fixed distance.

Advantages:
- Accurate recognition of fine targets/areas such as iron towers.
- The LiDAR has a very small size and is suitable for integration into unmanned inspection aircraft or embedded in narrow cabin spaces.

Main Functions:
- Vertical altitude determination: It can provide highly reliable true altitude measurement data with the highest centimeter level accuracy, effectively compensating for the poor ranging accuracy of barometers and GPS in complex environments near the ground, and assisting drones in achieving highly reliable altitude determination flight. In addition, in scenarios that require precise delivery of goods (such as medical emergencies, emergency supplies distribution, etc.), delivery drones can hover at a specific altitude and accurately deliver goods through a fixed altitude flight mode.
- Fixed distance: A converging laser with a divergence angle of less than 0.5° can ensure accurate alignment of fine structures smaller than 10cm on the measured object at a distance of 10m. In tasks such as aerial photography and scientific observation, there is no need to be distracted by controlling the distance between the drone and the object being measured, thereby improving work efficiency and ensuring image quality.
- Assisted landing: The measurement accuracy gradually improves as the measurement distance decreases, with an accuracy of <±10cm within 10m, meeting the high-precision measurement requirements of assisted landing within this critical distance. During the landing process, the drone can autonomously adjust its flight attitude and speed based on the information provided by the LiDAR without human intervention, ensuring a stable and accurate landing at the designated location and reducing the risk and cost of manual operation.
- Ranging, marking, and precise positioning: In conjunction with the image sensor mounted on the drone, real-time measurement of target objects as small as 1.5m from a distance of up to 170m provides ±(0.1m + measurement distance x 0.5%) relative distance information to the drone for points of interest in the image. Meanwhile, by combining GPS data, the absolute coordinate position of the point of interest can also be calculated.
