DTOF FHL-LD19 Lidar Working Environment
Environment
- DTOF FHL-LD19 Ladar is basically a laser triangulation measurement system.
- It can work excellent in all kinds of indoor environment and outdoor environment without sunlight.
DTOF FHL-LD19 Distance Range
Ranging range:
DTOF FHL-LD19 has a sampling rate of 8000 times/s. In addition, The laser ranging distance can reach up to 12 meters Based on white objects with 70% reflectivity,so it can collect environmental information at a rather high speed and accuracy,
Laser Triangulation Measurement System
360 Degree 2D Scanning:
The ranging core of DTOF FHL-LD19 rotates clockwise, performs 360 degree 2D omnidirectional laser range scan on the surrounding environment, and generates an outline map. configurable scan rate from 5~13Hz, Typical 10Hz.
DTOF FHL-LD19 ’s Working Time
Service life: up to 10000 hours
- up to 10000 hours

Pequeño, liviano y muy útil al momento de integrarlo a la robótica

The LD19 driver apparently calculates the number of readings in a scan in a non-conformal way and is out of spec with what the ROS2 SLAM Toolbox expects. The maintainer of SLAM toolbox has asked maintainers of LIDAR drivers to fix the calculation on their end, this is manufacturer won't respond.With the current LD19 driver, the SLAM Toolbox will discard around 70% of scans from the LD19 (see graphic below) and is largely unusable. This LD19 driver needs to be updated to always output the same number of readings in every scan and not repeat 0 degrees and 360 degrees. The output range should be [0,360) not [0,360].

Software was a bit hard to find but onces I found it it works as advertised and is the cheapest I been able to find.

I love the size of this FHL-LD19 lidar. This would be an awesome little lidar package if it worked out of the box with ROS2 SLAM package. It's small, has a decent scan rate and has decent distance. I'll have to dig deeper into the issues with SLAM and see if anyone has been able to modify the firmware. Overall, it's a neat little lidar package, unfortunately it just isn't usable with ROS2 for a robot as is.
