Mavis 17.01

Mavis 17.01 is available.

Mavis provides color calibration using the X-Rite ColorChecker® Classic

 

Color calibration is required for consistent analysis of vegetataion indices as well as to adjust the white balance for scientific interpretation. Mavis provides calibation regadring the white balance or reflectance values for RGB data as well as different filters for converted cameras (RGN | red filter, NGB | blue filter, NGN | Agrowing NIR)

 

Mavis provides full support for the Agrowing QX1 camera

Agrowing’s modified Sony QX1 multi-spectral is a high-end agricultural multi-spectral camera, which is designed based on Agrowing’s patent pending lens technology.

 

Agrowing’s camera provides about 8 Mega Pixel resolution per color channel, with less than 1% distortion. Resoltion varies between 7.3 and 8.2 Mega Pixel depending on the settings. Agrowing’s camera has exchangeable NDVI and Red-Edge narrow bands lenses. The NDVI lens acquires 450nm, 550nm, 650nm and 850nm, and the Red-Edge lens acquires 450nm, 550nm, 710nm and 850nm.

Agrowing’s camera is based on a modified Sony ILCE QX1 camera. It weighs 335g (including battery and lens). Agrowing also developed a lightweight (40g) passive Nadir gimbal, which exploits the camera weight to keep its vertical position at all times, without consuming any battery power.

The combination of high resolution, narrow bands and low distortion with the possibility to exactly match the RGB and NIR data in Mavis makes Agrowing’s camera a unique product in the market.

The camera records the RGB and NIR data on a single image sensor. Hence, the images must be preprocessed before any photogrammetrical analysis.

Based on the dual-lens images Mavis generates two exactly matching Orthomosaics – one for the narrow band RGB lens and one for the NIR lens. These can be used to derive vegetation indices using the dual camera option in Mavis.
