We all know the R3 is going to outperform the l2 in every regard except price. It turns into an issue of budget and deliverables. A price comparison might help with weighing that out. Including the added benefit of slam with the r3p.

Totally! But, you do get what you pay for. And right now, the R3 Pro V2 has some very competitive pricing options for the full package deal with unlimited use of all its features. Join us for a group session (no hassle) and we can tell you more about it... www.rockrobotic.com/talk-to-sales

I believe you should have done the comparison with optimised on and smoothed off. I would really like to see that comparison. Is the R3 data completely raw or has it been optimised or strip aligned etc?

Great detailed comparison! Looking forward to the under-the-tree data sets comparison.

I shot thick woods with the L2 and rarely needed more than 3 returns. If you're shooting thick woods just fly slower you'll get through the brush

@pistolpete65 16 күн бұрын

That would be fine, but if the ROCK only gives you 2 returns.... where do you stand? Are you saying fly with the ROCK just more slowly?

@IndianaDrones 14 күн бұрын

It's really not about the number of returns the LiDAR has. It's actually about how useful the returns are. How useful is 5 returns if they're not all accurate?

Was L2 set to repetitive or non-repetitive? Would be interesting to see how other Lidar desktop software adjusted the data. TerraScan drone processing wizard perhaps?

@SkyLensStudios 13 күн бұрын

Do you use the pilot2 mission plan for the L2 and just run the R3? Does the L2 calibration sections of the flight work with the R3???? I have a mission we are flying both sensors in a day and need advice on using the pilot2 app to control the flight’s?

I find in other software that the smooth tool is problematic, especially in that curb scenario. What does it look like just optimized (trajectory alignment, boresight adjustment, etc.)?

@thomasterwilliger604 16 күн бұрын

The big difference is the price of the units themselves and even more so the monthly cost of the software. The difference in cost of the software is the real significant difference. It appears the quality is better on the R3 but not sure if the added quality is necessary for most land survey mapping and justifies the cost of the software. Before making a decision to buy these products consider the cost of the software.

@IndianaDrones 16 күн бұрын

L2 is roughly $1,500 per year and The R3 Pro is $2,000 per year. Not a huge difference

@RuebenMiller 15 күн бұрын

I believe DJI Terra offers a perpetual option at $4400 with occasional update costs if you want to update. It is difficult to justify the $2000 or $1500 a month just to get your point cloud, especially if not using all the time in a seasonal climate area.

Is a 'return' how many times it measures the same point?

@nasoskatsampoulas7150 14 күн бұрын

Not exactly. Think of a laser as a cylinder with a diameter. That pulse hits a leaf with (let's say) 25% of the "cylinder's" area, another 25% hits the bush underneath and the rest of the beam hits the ground. A lidar with 3 returns can measure all of those 3 different points, whereas another with 2 returns can measure only the first 2.

Great video. I own the L1 and have been thinking about upgrading to the L2 but this makes me think twice. Like, does it really make sense to spend $12,500 on the L2, just to try to use the Terra license I already have? (btw the Terra perpetual was $4k for me, purchased in 2023.) It seems like the weirdness of the L1 has not been fixed by DJI. I was really hoping it would be. I agree with others in the comments - you can make the L2 work for you if you understand its limitations, and if you are transparent with your clients about what you are delivering... But it might make more sense to just finance a more expensive sensor and know that you are doing the best you can do...Thank you!

The clear precision advantage of Rock R3 versus DJI L2 may not be sufficient to justify the double-fold price increase, however; the SLAM feature of Rock R3 is well worth the extra cost enabling indoor mapping and modeling. The modular architecture of Rock R3 is still another outstanding feature. If I were Rock Robototic, I would create a symmetric modular chassis with individual or group slide-lock payload capability. I would thus present a full-frame Rock FX camera module with a mechanical shutter and a 60 mpx sensor to replace the DJI L2 + DJ P1 combo all at once.

The L2 is 12k and the R3 starts at 25k. For someone just starting and learning cost makes a big difference. Would flying slower help on the L2? Is there a different outcome on a M300 vs M350? If you have a half circle reflection on the R3 side not being used, does it help the data?

@carlobardi 16 күн бұрын

R3 starting at $25K where? Mine was $30K and now they want $2k+shipping for the V2 upgrade.

L2 works great. Outperforms the R3 and at a third of the costs. Plus live results.

Outperforms, how? The L2 isn't SLAM capable. Did you watch the video?

@IndianaDrones 14 күн бұрын

Yeah, $2K to upgrade the original unit to an entirely upgraded system. The new capabilities are more than worth it. And, we're offering incentives to cut that upgrade price more than 50% if you share on your socials. We think this is a pretty fair opportunity.

So even at 30m altitude it will not pass as a usable surveygrade data, so whats the point of L2? Why would anyone use it.

This looks like a Non-repetitive path scanning for L2. I'm not using it due to this kinda bad result. Total different story for the repetitive scan path, which is very accurate and precise even without smoothing and optimization. I'm super satisfied with my L2 unit in rep mode. I've noticed also a thing: i'm always using an Emlid RS3 set as base when using lidlar, with short baseline data precision increase drammatically, and also doing PPK. Your dataset looks acquired in worst condition possible.
