Embodiment Construction

[0056] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0057] The present invention takes the pothos as the research object, shoots the pothos with a consumer-grade RGB-D camera, obtains the local point cloud of the pothos under a single angle, processes the point cloud data, and performs matching optimization with the pre-established geometric model of the pothos leaf , proposed a method to obtain the leaf size and leaf area of ​​the pothos based on the local point cloud.

Abstract

The invention discloses a three-dimensional estimation method of epipremnum aureum leaf external phenotypic parameters based on a geometric model. The method comprises the following steps: S1, establishing a geometric model database of epipremnum aureum leaves; s2, fixing the angle and height of an RGB-D camera to perform primary shooting on scindapsus aureus to obtain local point cloud data of scindapsus aureus leaves; s3, performing space matching and parameter optimization on the local point cloud data obtained in the S2 and the geometric model database in the S1 to obtain a closest geometric model; and S4, calculating a blade external phenotypic parameter of the geometric model to serve as an estimation result. According to the estimation method disclosed by the invention, the plant leaves do not need to be separated, a shooting instrument does not need to change the angle, and the external phenotypic parameters can be estimated only through one-time shooting. The error range of the estimation result is small, and the estimation result is very stable.

Description

technical field [0001] The invention relates to the field of estimation of plant growth state, in particular to a three-dimensional estimation method for external phenotype parameters of pothos leaves based on geometric models. Background technique [0002] Pollen belongs to the Araceae family and belongs to the genus Tengyu. It is native to tropical regions and has strong vitality. It has low environmental requirements and is easy to cultivate. It can survive in both soil and water. As one of the most widely used indoor and outdoor foliage plants in my country, pothos is evergreen in all seasons, has strong vitality, high plasticity, and has certain ornamental value. And it can purify the air and absorb harmful substances such as formaldehyde, benzene, toluene and nicotine in the air. Tall, widely cultivated important ornamental plant, loved by consumers. Due to the continuous improvement of people's living standards, the demand for using pothos to decorate and purify ind...
