I've been looking around for a lidar/radar rangefinder for a few months now and can't seem to find anything reasonable for my application. My requirements are pretty straightforward:
- 100m range
- I2C or other serial protocol
- Accuracy +/- 0.25m
- Sampling > 50hz
This isn't a spinning/mapping application, so sampling rate isn't very demanding, and I don't think I'm asking much regarding accuracy, but I can't find anything for less than $600. It seems like there's a bit of a hole in the market?
The closest ive come is the lidar lite from pulsed lite (now Garmin), but its only good up to 40m, and I've had one backordered for 4 months now! If they offered this product in an 80 or even 60m application it would help me, but 40m isnt quite enough.
I would assume the technology/demand just isn't out there that anyone is cheaply Producing this device, but I see lots of lidar based rangefinders for golf courses/gun sitting/etc that are around $100 in price and work in these ranges. What's different about these technologies? Example. What technology does this use and are there sensors out there that I can buy direct?
Also found this, but seems specific to altimeters. Is there something about this device that would only make it applicable for drone altimeter applications? I know there must be considerations for the incoming environmental light and reflectiveness of the surface it's detecting,so possibility it wouldn't work in an outside application where environmental lighting will vary? And also this device doesn't call itself 'lidar', so let's ask a very basic question:
Are all laser rangefinders considered 'lidar'? Surprisingly I haven't found this answer.
