Problems solved by technology

However, this technique also has two insurmountable weaknesses that limit its application in root measurement and research
One is that when using this technique, the root system must be sampled from the soil. This destructive sampling method is bound to make it difficult to maintain the original state of the root system—thus making the accuracy of later measurement lose practical significance; Especially the root system of crops, the phenomenon of staggering and occlusion among the roots is very serious-this poses a fatal problem for stereo vision measurement technology

Embodiment 1

[0033] see figure 1 . The in-situ measuring method of plant root geometric configuration of the present invention specifically comprises the following steps:

[0034] Take banyan saplings as an example.

[0035] (1) Select potted root samples, plant them for more than 1 week, and carry out proper packaging treatment to ensure that the scanning process is safe, clean and accurate;

[0036] (2) Carry out preparatory experiments and determine the scanning scheme. According to the specific equipment and root sample characteristics, select the scanning parameters. Such as MSCT tube voltage, tube current, pitch and layer thickness and other technical parameters.

[0037] (3) Scan the root sample, put the root sample vertically into the scanning surface bed, fix and calibrate the position, go through the pre-scanning space range, scan according to the selected scanning parameters, obtain the in-situ tomographic sequence image, and store the image The sequence is stored in the su...

Abstract

The method includes steps: using imaging device of biomedicine obtains layered sequence images in situ of root system of plant grown at different opaque medium. Processing and analyzing the sequence images obtains spatial geometrical characteristic parameters in situ of root system of plant. Based on the said parameters, model of solid geometry is built. 3D visualized reconstruction is carried out for model of solid geometry so as to build 3D display model of root system. Features are: obtaining images in situ of root system of plant precisely and in non-destructive, sampling procedure is simplified so as to save labor to separate soil, greatly raised accuracy.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, in particular to an in-situ and non-destructive measurement method for the geometric configuration of plant roots. Background technique [0002] The root system is an important organ for plants to obtain nutrients and water from the medium environment such as soil. The ability of plants to absorb nutrients and water largely depends on the morphological distribution of their roots in the medium environment. Therefore, as early as the 18th century, people began to systematically study the root system of plants. Soil and other media are the underground environment that plants rely on for survival. While providing nutrients and water to plant roots, they also set up insurmountable barriers for in-situ observation and direct measurement of roots. The special growth environment (opaque, invisible) and complex morphological structure (interlaced, occluded) of plant roots make it much more ...
