Drones have long been used to help map and survey assets from the sky. That’s because, when it comes to visual inspection, UAVs offer a significant time efficiency advantage over traditional on-foot data collection methods.
But ease is one thing — accuracy is another.
From erosion inspection to 3D cell tower mapping, the ability to precisely identify areas of concern is paramount to companies managing multi-million dollar assets. Drones have proven to be up to the task, but with the announcement of Zenmuse’s new P1 and L1 cameras, UAVs are set to change the way we see surveying, 3D modeling, and mapping forever.
Let’s start with the P1.
Zenmuse P1-Full Frame – The New Benchmark for Aerial Surveying
Set for compatibility with DJI Enterprise drones, the P1 is designed for photogrammetry missions. The robust versatility of the low-noise, high-sensitivity sensor ensures greater control, accuracy, and capture efficiency simultaneously from both 2D and 3D models.
The camera itself has been upgraded to 40 megapixels, and can be outfitted with 24, 33, and 50mm lenses. Coupled with a capture system at a GSD of 3cm, an 80% front overlap rate, and a 65% side overlap rate, this payload is more than ready to replace your traditional photogrammetry systems.
But that’s not all.
It’s also outfitted with a 3-axis gimbal with Smart Oblique Capture, a full-frame sensor that can take a photo every 0.7 seconds, and a global mechanical shutter with the new TimeSync 2.0 system.
The point? You can now accurately cover over 3 km of photogrammetry data in a single flight. This means that, in a single workday with the P1 camera, you can easily cover 7.5 km of elevation mapping, 3D modeling, and more.
However, if you’re looking to dive even deeper into aerial surveying, then the Zenmuse L1 deserves your attention.
Zenmuse L1- A Lidar & RGB Solution for Aerial Surveying
Are you looking to add real-time 3D data to your DJI Terra or Matricce 300 RTK? What about true-color point clouds for immediate insights onsite? Then the Lidar capabilities of the L1 are for you.
This Lidar module of Zenmuse’s new lineup sports an IP44 rating that lets you accurately scan in rain, fog, or at night with a 70 degree FOV and visible light camera with a 1-inch sensor.
But the real star here is the laser light used in the camera for unparalleled data precision at 240,000 points per second. With raw information at this magnitude, the L1 was built to acquire and communicate critical dimensions on the point cloud model using measurements and annotations.
It also allows users to cross IMU and GNSS data for point cloud and visible light calculations, along with POS data calculations, to effortlessly generate reconstructed models and accuracy reports.
Which is right for me?
Both the Zenmuse P1 and the Zenmuse L1 were built for the mapping and surveying market, but that doesn’t mean that their capabilities fully overlap.
Stunningly accurate modeling, surveying, and mapping can be achieved with each, but the Lidar capabilities in the L1 will put it out of the price range of those looking for photogrammetry needs outside of ground surveying for construction. The P1’s focus on photogrammetry and frugal design makes it more appealing to companies looking for building, erosion, and damage inspection, while the L1 is geared towards large-scale surveying with pinpoint laser accuracy requirements.
Regardless of the model you choose, both further legitimize drones as the most efficient, safe, and now accurate source of data inspection and analysis from the skies.
