DJI Zenmuse L1 and DJI Zenmuse P1 are the last two proposals presented by the Chinese manufacturer regarding the world of professional drones . According to the company, these are important innovations to the point of “changing the rules of the game” by focusing on efficiency and an affordable price. All without reducing the quality and precision in data collection.

In the case of L1, it is essentially a new LiDAR system that can be integrated into professional drones useful for surveys , mapping and for those in the construction sector. With DJI Zenmuse L1 we aim to provide a useful tool for precise measurements in particular conditions (low light, dense vegetation) or where photogrammetry cannot be used satisfactorily.

DJI Zenmuse L1: the evolved LiDAR system for professional drones

DJI Zenmuse L1 is the first unit from the manufacturer that uses the Livox LiDAR module that combines lightness and FOV of 70 °. To capture images, we rely on a MPixel CMOS sensor with 1 “size with mechanical shutter and 3-axis stabilizer. Vertical accuracy is 5cm while vertical accuracy is 10 cm.

It is thus possible to generate clouds from 240 thousand points every second and get to capture areas extended up to 2 km ² with a single flight, all with speed, precision and few complications. There is linear scan or non-repetitive scan mode (data is acquired not along a defined plane but from any direction).

To ensure that Zenmuse L1 can be used as many days as possible, the system is IP certified 44 and therefore managing to operate even in fog or light rain. The dimensions are equal to 152 x 110 x 169 mm with a weight of 900 grams. No information has yet been provided on precise availability (will arrive early 2021) and prices that may be revealed in the future.

DJI Zenmuse Z1: full frame photogrammetry system

DJI Zenmuse P1 is a solution dedicated to photogrammetry that uses a full frame sensor from 45 MPixel (4.4 μm large pixels) with mechanical shutter and low noise. This system is designed for those who work in architecture, engineering, construction and surveys but who do not want to resort to LiDAR systems, but still being able to make 2D ortho-mosaics and oblique images for 3D modeling.

The optical part uses fixed lenses interchangeable with focal lengths of 24 mm, 35 mm and 50 mm (all with aperture of f / 2.8) plus a 3-axis stabilizer. The accuracy allows you to reach 3 cm horizontally and 5 cm vertically as well as being able to cover 3 km ² in a single flight, thus reducing operating costs and time required. Furthermore, there is also the IP4X certification.

The system is not missing TimeSync 2.0 so as to synchronize the time between the modules by acquiring data
