Sailhero Environment has launched a tower-based hyperspectral remote sensing system, pioneering a new model for water environment monitoring. Adhering to innovation-driven development, Sailhero has independently developed the equipment and system, introducing the “tower-based hyperspectral remote sensing system.” This breakthrough achieves professional-level full-process inversion from instrumentation to tower installation and water quality parameter measurement, while also advancing the transformation of traditional river, lake, and marine water quality monitoring from point-based to area-based monitoring. The tower-based hyperspectral remote sensing system will provide more effective and precise technical support for water environment monitoring The tower-based hyperspectral remote sensing system is designed to mount a high-spectral spectrometer on a tower or mountain peak to perform oblique scanning imaging of target areas. It enables continuous monitoring of the environment within a specific range, acquiring images and spectral data at high frequencies over extended periods. This data is then processed using inversion models for analysis. It can invert more than 15 water quality parameters, including suspended solids, turbidity, transparency, zinc, copper, lead, chlorophyll, chemical oxygen demand, dissolved oxygen, total phosphorus, total nitrogen, and nitrogen. The data processing of the tower-based hyperspectral instrument can achieve near-real-time data processing, providing timely warnings for water pollution incidents and providing evidence for pollution source tracing. Technical Principle The spectral image data cubes obtained by the hyperspectral imaging system feature ultra-high spectral bandwidth, high spectral resolution, and high spatial resolution. Hyperspectral remote sensing imaging technology has the characteristic of “image-spectrum integration,” enabling the simultaneous acquisition of both spatial images and continuous spectral information of objects. Therefore, hyperspectral images contain more abundant target information compared to panchromatic or multispectral images. The system offers longer operational durations compared to drone-based system and can conduct continuous monitoring under adequate lighting conditions. The tower-based hyperspectral remote sensing system enables near-real-time data processing, allowing customers to remotely access water quality parameter distribution data in real time. Additionally, the inclined scanning imaging range is relatively large, making it suitable for deployment at locations such as water gates, confluences of tributaries, estuaries, and waterfront mountains. It can diagnose challenges encountered in water pollution prevention and water quality compliance, providing a basis for decision-making. ● Contaminated water bodies exhibit unique spectral characteristics distinct from those of clean water bodies; ● These spectral characteristics manifest as absorption or reflection of specific wavelengths of light, and these spectral characteristics can be captured by imaging hyperspectral instruments and reflected in remote sensing images; ● The left figure shows the spectral curve characteristics of typical soil, vegetation, and water bodies, while the right figure shows the spectral curves of water bodies with different turbidity levels.
