Launched in late 2019, MicaSense’s dual camera system doubled the spectral resolution of the company’s previous 5-band sensors, offering professionals a new 10-band synchronized solution for advanced remote sensing and vegetation research applications.
Build from the original RedEdge sensor, which has 5 bands including rgb as well as red, red and near infrared bands, the 10 band system adds coastal blue band, green band and three bands in the red to red region of the spectrum. Packaged with the mounting hardware already attached to the cameras in a hard carrying case, the complete kit includes streamlined drone integration with the camera out of the box.
“If you have a DJI drone, you lock the camera gimbal port, then install the DLS 2 [MicaSense’s Downwelling Light Sensor]”Emily Ciesielski, Channel Sales Manager at MicaSense, told Commercial UAV News. “You attach it to your drone, then there’s a cable that runs from the DLS2 to the camera itself. So the installation is pretty quick and it’s just as easy if someone already has a RedEdge camera as we will provide the blue camera and the bracket, so they just need to attach their RedEdge to this bracket.
Earlier this year, Commercial UAV News and MicaSense published an on-demand webinar regarding the capabilities of ‘superspectral’ imagery and how the Dual camera system opens the door to a wider range of use cases. Whether it’s classifying, identifying species, or trying to find harmful weeds or algae blooms, the additional bands provided by the MicaSense solution allow users to spot things that aren’t. not possible with the naked eye or using a 5-band system. While MicaSense has built a large customer base with the original RedEdge and Altum sensors within agricultural research and service providers, the development of 10 bands is helping the company reach new, more work-oriented research communities. environmental monitoring, as well as another type of service provider.
“Oil and gas or mining companies often have to do reclamation work, to help them design and conduct this reclamation work, they can hire an environmental consultant,” Ciesielski said. “The objective is to restore the land to its natural state or to what it was before the exploration work. The multispectral bands are really helpful in monitoring this, tracking the regrowth of vegetation and the species composition in the reclaimed area. “
With 10 bands strategically located at key points along the plant’s reflectance curve, one of the main advantages of the dual camera system over the 5 band sensor is the improved capacity for species classification work, where the focus is specifically between red and near. infrared part of the light spectrum. While there can be a lot of variation and reflectance in this section of the light spectrum between different species, using the two red bands and three red bands of the 10-band system makes it easier to find the unique spectral signature of a species or the composite of several species in an area. With the 10-band system, what would otherwise be an essentially uniform green area to the human eye becomes usable data as different species are highlighted. It is also an effective tool for finding invasive species that can spread quickly or are poisonous in one way or another, as well as distinguishing weeds from a crop in a field where both have a wide leaf structure.
In addition, the 10-band sensor is more suitable for aquatic and marine applications than a traditional 5-band sensor. For example, the aerosol blue band is particularly useful for imaging shallow water if you are looking for suspended sediment, algae growing on the water, or vegetation below.
“It has a lot to do with how water absorbs light, rather than reflecting it, so this specific blue band is the one it reflects more,” Ciesielski explained. “It’s especially useful for mapping the coastal environment, where they have the shoreline as well as some vegetation. Maybe they want to look at the makeup of the species in addition to the health of the water and anything suspended in the water.
Additionally, mapping areas where you don’t need to be as granular as knowing all specific species with the 10-band sensor, such as wetlands, allows users to analyze the percentage of trees. compared to shrubs compared to tall grass compared to water in the area. . It can help to see how this composition changes over time, either as a result of human action, restoration efforts, or climate change.
“Having these bands to detect and monitor land and water areas gives you a lot more information or tools to do a much better job, but it’s also for the people who do a lot of work in the area. satellite community, ”Callum Scougal, Sales Engineer at MicaSense, added. “They’re used to having 10 or more tapes and our system directly reflects that in terms of tape capacity. [With the 10-band sensor], people in the satellite community who wish to validate high resolution models can do so using the highest spatial resolution. And it’s also particularly useful for those who want to develop classification algorithms or deep machine learning.
