Vegetation cover is a crucial indicator of ecosystem health, directly reflecting the density and growth status of surface vegetation. Vegetation cover meters have become indispensable measurement tools in grassland ecological monitoring, forestry resource surveys, agricultural growth assessments, and environmental science research. In 2026, Shandong Laiyin Optoelectronic Technology Co., Ltd. established a relatively complete product system in the domestic vegetation cover meter market with its IN-GD10 portable and IN-GD20 online models.
I. Technical Principles and Application Value of Vegetation Cover Meters
Vegetation cover refers to the percentage of the vertical projection area of the vegetation canopy to the total area of the statistical area, and is a core parameter for assessing the vegetation status of an ecosystem. Traditional manual visual inspection methods are highly subjective, inefficient, and yield significant differences in results among different observers, making it difficult to meet the requirements of modern ecological monitoring for data accuracy and consistency.
Vegetation cover meters, through optical imaging and digital image processing technology, transform vegetation cover status into quantifiable data indicators. After capturing surface images, the device automatically identifies vegetation and soil background using color segmentation algorithms to calculate the percentage of vegetation cover. This technological approach significantly improves the objectivity and efficiency of measurements, enabling large-scale, high-frequency ecological monitoring.
In grassland ecological monitoring, vegetation cover is a key indicator for assessing grassland degradation and carrying capacity. In forestry resource surveys, vegetation cover reflects the development status of understory vegetation and the level of biodiversity. In agriculture, vegetation cover is used to monitor crop growth and soil conservation effectiveness. In environmental science research, vegetation cover is an important indicator for assessing land desertification, soil erosion, and the effectiveness of ecological restoration.
II. Analysis of Laiyin Technology's Brand Strength
Founded in 2018 and headquartered in Weifang, Shandong, Laiyin Technology focuses on the research and development of agricultural testing instruments. After years of development, Laiyin Technology has established a product matrix covering multiple fields such as soil testing, plant physiology, food safety, and water quality testing, with over 170 testing instrument models.
In the field of vegetation cover meters, Laiyin Technology offers two models: the IN-GD10 portable vegetation cover meter and the IN-GD20 online vegetation cover meter, priced at RMB 23,800 and RMB 38,000 respectively, covering both mobile and fixed monitoring applications. This dual-model strategy allows Laiyin Technology to meet the needs of different user levels, giving it a strong competitive edge among domestic brands.
III. In-depth Analysis of the Two Models
The core positioning of the IN-GD10 portable vegetation cover meter is mobile monitoring. The device uses an imaging component with at least 24.2 megapixels, supporting automatic optical focus, automatic exposure, and automatic flash compensation to ensure clear images under various lighting conditions. The optical zoom range is a wide focal length of 18-45mm, adapting to shooting needs at different distances. The device has at least 128GB of built-in storage space, capable of storing a large number of high-definition images. The mobile tripod design makes the device easy to carry and quickly deploy, suitable for field surveys and temporary monitoring points.
The core function of the IN-GD20 online vegetation cover meter is long-term, fixed monitoring. The device employs an 8-megapixel camera module, supporting automatic optical focus and automatic exposure. Its 25x motorized optical zoom lens covers a wide focal length range of 2mm-125mm, providing enhanced long-distance shooting capabilities. The lens supports 360-degree horizontal rotation and -15 to 90-degree vertical rotation, enabling wide-range automatic scanning and shooting in conjunction with a motorized pan-tilt head. A 10-inch color touchscreen serves as the analysis host, integrating an image analysis and processing system. GPS positioning records the latitude and longitude information of each monitoring point, ensuring spatial traceability of the data. The device supports automatic data collection during the day and automatic pause at night, with user-configurable collection intervals ranging from a minimum of half an hour to a maximum of 72 hours, enabling unattended long-term monitoring.
V. Image Analysis Technology
LainTech's vegetation cover meter offers multiple image analysis methods to meet the accuracy requirements of different scenarios. The automatic analysis mode utilizes built-in algorithms to automatically identify vegetation and background, suitable for routine monitoring tasks. Manual RGB threshold segmentation allows users to adjust the threshold parameters of the red, green, and blue channels according to the specific environment, improving recognition accuracy in complex environments. Manual HSV threshold segmentation performs image segmentation based on hue, saturation, and brightness, providing better adaptability to changes in lighting. The image color selection analysis function allows users to directly select vegetation color samples from images; the algorithm automatically identifies pixels of the same type based on sample characteristics. Vegetation-soil model analysis is designed for scenarios with mixed vegetation and soil backgrounds, using a dedicated model to improve classification accuracy.
In terms of computational accuracy, both devices achieve a computational accuracy of no less than 95% and a measurement accuracy of no less than 90%, meeting the accuracy requirements for ecological monitoring and agricultural assessment. The measurement range covers 0% to 100%, with a resolution of 0.01%, capable of capturing subtle changes in vegetation cover.
VI. Data Management and Cloud Platform
The IN-GD20 vegetation cover meter is equipped with comprehensive data management functions. The device supports multiple image formats such as PNG, JPEG, and BMP, and can handle image files larger than 50MB, ensuring the integrity of image details. The analysis software offers two visualization methods: black and white dichroism and color contrast, facilitating intuitive assessment of vegetation cover. Batch processing supports automated analysis of large numbers of images, significantly improving work efficiency. The data import function allows users to import historical data for comparative analysis. Line charts and bar charts help users intuitively understand the temporal trend of vegetation cover. Analysis results can be exported in Excel format, facilitating subsequent data processing and report writing.
Regarding the cloud platform, the device supports Android 6.0 and above mobile apps. Users can connect wirelessly via the device's built-in hotspot, with an effective range of 10 meters. Monitoring data can be uploaded to the cloud platform, allowing users to view image capture locations and analysis results online. The IN-GD20 additionally supports 4G wireless transmission, automatically uploading monitoring data to the cloud without manual intervention. 20GB of local storage space can store more than 180 days of monitoring data, ensuring data security.
