Embodiment 1

[0055] The method for checking and accepting plant specifications in landscaping engineering disclosed by the invention comprises the following steps:

[0056] Plant category (arbor, camphor), required measurements: plant height, crown width, diameter at breast height, the values ​​are: plant height 3560cm, crown width 267cm, diameter at breast height 13cm, obtained by manual multiple measurements, see figure 1 , the required time is 11 minutes, and there are potential safety hazards in the crown width measurement.

[0057] The smart phone camera is turned on; point the camera at the plant to be accepted, press the shutter, take a photo, obtain the color of the plant, and then perform conventional grayscale and binarization on the photo, and routinely perform plant morphology analysis based on the results Curve fitting to obtain the curve type, slope, major and minor axis size, and major and minor axis ratio data of plant morphology; by comparing with the data in the database ...

Embodiment 2

[0061] Plant category (shrub, golden leaf privet), required measurement: density, plant height; plant height is 50cm, density is 25 plants / square meter, obtained by manual multiple measurements, the time required is 6 minutes, and the number of plants is 220 ,See Figure 5 .

[0062] The smart phone camera is turned on; point the camera at the plant to be accepted, press the shutter, take a photo, obtain the color of the plant, and then perform conventional grayscale and binarization on the photo, and routinely perform plant morphology analysis based on the results Curve fitting to obtain the curve type, slope, major and minor axis size, and major and minor axis ratio data of plant morphology; by comparing with the data in the database (including about 200 common garden plants), identify the type of plant, and it is Golden Leaf Girl Chastity;

[0063] When the plant is a shrub, the density measurement of the shrub includes two steps: 1) volume measurement; select a reference...

Embodiment 3

[0067]A garden arbor and shrub plant in Xinjian Park, Suzhou was used for acceptance, and the method of the present invention and the existing manual method were used for comparison. Based on 100 trees and 500 shrubs, three measurements were carried out. For plant identification, the method of the present invention is consistent for three identifications, and after rechecking, all are correct. In the existing manual identification, the three results are different, and there is an error of about 15%. For the overlapping part, after rechecking, the correct rate is 89%; for the characteristic parameters, this The inventive method has a high degree of approximation for three-time recognition, and the error is less than 3%. In the existing manual measurement, there is an error of about 7% to 10% in the three-time results.

[0068] The invention proposes a method for acceptance based on mobile phone photography. In the construction acceptance of landscaping projects, it involves the ...

Abstract

The invention aims to provide a construction acceptance method for a tree and shrub plant specification in landscaping engineering. By use of the method, through the photographing and camera shootingfunction of a mobile phone, on the basis of photo identification, a ranging function is realized, so that a user quickly obtains the type and the relevant size of a plant, and a construction drawing is compared to finish the construction acceptance work of the plant specification. By use of the method, the problem of huge price differences due to inconvenient data measurement in the existing plantconstruction acceptance is solved, and in addition, the professional requirements of users can be lowered through photographing identification and comparison functions.

Description

technical field [0001] The invention relates to a method used in the field of construction acceptance of landscaping projects, in particular to a method for construction acceptance of tree and shrub plant specifications in landscaping projects. Background technique [0002] Landscaping project is the project of constructing landscape garden green space. Landscaping is a place to provide people with a good rest, cultural entertainment, closeness to nature, and satisfy people's desire to return to nature. It is an important measure to protect the ecological environment and improve the urban living environment. Among them, the design and application of plants play a vital role in the landscaping project. The acceptance of landscaping projects is an important link after the design and construction. The acceptance of plants is limited by technical conditions, and the acceptance of trees is only based on the DBH acceptance. , The measurement data of shrub density and plant height...
