Product Name: Digital Leaf Area Meter

Model: YMJ-C

1. Introduction

Intelligent digital leaf area measurement system by the image acquisition device and load of self-developed software flat measurement algorithm using the company years of accumulation area, according to the blade contour feature extraction, graphics, physical transformation, such as edge detection technology, to be able to image and can be measured rapidly blade parameters such as area, perimeter, wormhole number. Compared with the traditional leaf area, this measurement is simple, the results more objective, more rapid data diversity and greatly reduces the artificial operation error.

2. Characteristics

2.1 It can measure the leaf surface area of any irregular shape, any color, any thickness and the moisture content.

2.2 Fast measuring speed, simple. After preheating the machine, time of measuring each leaf surface area is less than 1 second.

2.3 It can save the leaf area measurement data and upload the datum to computers.

2.4 It has strong expandability. With wireless communication hardware interface, GPS positioning interface and so on. The hardware function can be expanded according to user demand. It can realize the remote transmission of spectrum data and GPS positioning and navigation function.

1, what is should be pay attention to the when the measuring?
1) open the software before please make sure the correct instrumentation, otherwise unable to open the software
2) scanner cameras must aim at blue bottom, make the software interface is covered by blue
3) when you measurement please note that don't are of strong light, as far as possible in a light even in the environment
4) please pay attention to person's stance, please don't keep out the light, can open the camera's built-in cases necessary to compensation light

2, how to speedy charge the plate?
Due to the flat screen and battery capacity and the relationship with big power consumption, current tablet slow charging is the common defects of all tablet, only pay attention to remember to close the screen when charging or off charging can be considered

3, support for several leaves measurement at the same time?
Currently only supports single leaf measurement
