5. Clever Calculation 3. Abundant Computing Power with Deep Openness

Based on DJI PSDK, it only takes 4 steps to efficiently develop 3 applications of Miao Suan:

M400+Smart Calculation 3 Third Party Development and Testing Case Sharing

Case 1: M400+Smart Calculation 3+Zenith H30, Intelligent Inspection of Fans without Stopping

Using M400 drone as the carrier, equipped with high-speed camera and MiaoSuan3 equipment, the wind turbine can perform fully automatic inspection without stopping.

(1) M400: The refined omnidirectional sensing performance brought by visual sensors, millimeter wave radar, and ring scanning lidar enables M400 to fly stably close to wind turbine blades.

(2) Miao Suan 3: It can seamlessly integrate with the underlying communication link, quickly obtain various sensor information of the drone flight platform, and natively support hardware stream encoding and decoding, which can quickly achieve functions such as stream acquisition, load and flight control.

(3) The overall solution can achieve autonomous flight, autonomous image collection, image data uploading to the system for automatic defect diagnosis, and automatic generation of inspection reports.

Case 2: M400 Tethered Power Supply Solution

(1) DJI's original captive battery supports lossless adaptation.

(2) DJI PSDK supports compatibility with tethered control systems and is embedded in the DJI Pilot 2 app; The entire mooring system can be controlled through the DJI RC Plus 2.

(3) Widely applicable: M400 supports high flight performance with a 6KG load, and has a wide range of applications in curtain wall cleaning, emergency lighting, relay communication, real-time monitoring, etc. when combined with mooring solutions.

Case 3: Solution for cleaning tethered curtain walls

(1) Higher Applicability: The M400 drone provides a small-scale cleaning operation platform, greatly improving endurance, load capacity, obstacle avoidance, and control capabilities, and providing strong support for intelligent operations, automated operations, and electrical mooring capabilities. It is suitable for complex and diverse urban scenes as well as irregular building operation scenarios, and is easier to transport, deploy, and operate.

(2) Higher safety: The safety and stability of M400 effectively resist flight disturbances during operations, support close range operations, and effectively avoid pressure attenuation caused by long-distance operations.

(3) Higher cleanliness: With the upgraded flight and control capabilities of M400, it can achieve precise large angle multi-faceted coverage, effectively dealing with irregular structures and highly concerned post wash water stains by customers.

Case 4: Building real-time SLAM and orthographic fast splicing algorithm based on Miao Suan 3

Based on DJI Magic Algorithm 3, we have developed and deployed real-time SLAM and orthographic rapid assembly algorithms, achieving a fully connected solution for the aircraft end (acquisition) → Magic Algorithm 3 (reconstruction) → cloud (rendering) → terminal (decision-making) on-site minute level closed-loop. This deeply empowers key areas such as basic surveying, energy inspection, emergency management, and smart cities.

(1) Real time performance: Relying on the powerful computing power of Miaohua 3, it achieves "flying and mapping at the same time, landing and mapping", shortening the traditional aerial survey data processing latency from "hour level" to "minute level" or even "second level", and changing the workflow.

(2) Lightweight: Breaking through the heavy reliance of traditional visual algorithms on large ground workstations, Miaohua 3 can complete core calculations on board, significantly reducing overall system energy consumption and deployment costs, and providing reliable support for harsh environments such as wilderness and emergency situations.

(3) Seamless "End Edge Cloud" Collaboration: Real time reconstruction results are instantly uploaded to the cloud and pushed to the command center and mobile terminals in real-time, achieving efficient collaborative command and decision-making across multiple roles and regions.
