Overview:
DJ-3200 digital plant canopy analysis system processes images to obtain data related to canopy structure, for example, leaf area index, light gap and gap distribution. The software can calculates radiation indicators, canopy indicators, light coverage at measurement sites, and distribution of direct and diffused light. Use a 180-degree fisheye lens and a 20.4 million high-resolution digital camera to take images from under the plant canopy or up from the forest floor, and then load the high-definition images of the digital camera into the software for analysis and processing.
Peculiarity:
· Images can be viewed in a variety of ways;
· Images can be converted to negative mode for viewing and analysis;
· Numbers can be defined for different sky areas: zenith and azimuth to define ranges;
· Leaf area of a single tree: can be directly output by software;
· Analyze local images: You can exclude parts of the image that do not need to participate in the analysis;
· Take photos: Try real-time control through Bluetooth and WIFI;
· Sky and foliage color filtering is possible;
· On-site acquisition, display and storage of color images of plant canopies, analysis software can manually adjust thresholds, automatic adjustment thresholds (OTSU);
· Custom output parameters: Users can define different output parameters according to different images.
