UAV Spectral Imaging Index Analyzer

Based on image-level (mosaic) multispectral filter imaging technology, airborne spectral imaging index analyzers based on industrial applications have been developed. Such as Shennong Specvision-A precision agriculture monitoring intelligent system, Dayu Specvision-W water environment monitoring intelligent system, Kunlun Specvision-F precision forestry and grass monitoring intelligent system, etc. It can realize river and lake (water pollution monitoring, suspected pollution source investigation, water ecological disaster monitoring, shoreline environment survey, black smelly water treatment), agriculture (planting status assessment, crop growth monitoring, crop collapse analysis, variable planting spraying, crop yield estimation), forestry and grass (forest physical and chemical parameters, forest structural parameters, forest water and fertilizer stress, forest pests and diseases, grass yield, grass cover, grass disaster, grass. It can provide users with first-hand information references with "one map" and provide technical support to solve users' painful problems. The spectral range, number of channels and performance parameters of the UAV spectral imaging index analyzer is shown in Table 1.

Eco-friendly spectral imaging index analyzer
 

Relying on spectral imaging technology, it strongly assists to intelligent environmental protection. Based on years of technology accumulation, Spectrum Vision strongly launches Dayu Specvision-W water environment monitoring intelligent system, which can accomplish real-time monitoring for applications such as water pollution monitoring, suspected pollution source ranking, watershed ecological disaster monitoring, shoreline environmental investigation, and black smelly water treatment. It can also obtain real-time distribution results of more than 20 water body indicators such as total nitrogen, total phosphorus, chlorophyll a, suspended solids, potassium permanganate index, algae distribution and eutrophication index, truly realizing real-time and efficient online analysis and monitoring of the water environment.

Tobacco Spectral Imaging Index Analyzer

China is a major tobacco growing country, tobacco is planted in all provinces of the country, its area and production are currently the world's largest, tax revenue in China's total tax revenue occupies a pivotal position, and has made considerable contributions to China's economic development. And China's total production of tobacco accounted for more than 80% of roasted tobacco, is the most important raw material for the production of cigarettes. For a long time, China has been using time-consuming, labor-intensive and costly traditional methods to observe and monitor the growth and quality of tobacco in tobacco fields. UAV spectral imaging technology is an efficient tobacco planting management tool, which can provide decision makers with fast and accurate tobacco growth conditions on a large scale and provide effective data for fertilization, irrigation and pesticide spraying, which can significantly improve the level of pesticide modernization and promote sustainable development of modern agriculture. Therefore, UAV spectral imaging technology has greater application value in tobacco field monitoring, and is a recent trend in tobacco field management.
