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 ...
