Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] Such as figure 1 As shown, a simulated measurement method for the area of ​​urine on the ground of a dairy farm, the steps are as follows:

[0035] Step 1: Build a collection platform equipped with a CCD camera and an IR camera. The lens of the CCD camera is located above the lens of the IR camera, and the field of view of the CCD camera covers the field of view of the IR camera.

[0036] The collection platform is a simulated measurement device for th...

Abstract

The invention provides a simulation measurement device and method for a urine area on the ground of a dairy cattle farm. The method comprises the steps of setting up a collecting platform provided with a CCD camera and an IR camera; manually forming a urine pit in the ground, placing a correction aluminum plate near the urine pit, correcting an obtained color image and an obtained IR image separately, and calculating and obtaining the actual area represented by each pixel in the color image and the IR image; extracting an urine pit region of the color image according to a threshold value, andcalculating the actual area of the urine pit; counting pixels in an urine pit region of the IR image, and calculating the actual area of the urine pit; obtaining a relationship model of the actual area of the urine pit in the color image and the actual area of the urine pit in the IR image through linear regression, and correcting an IR image measurement result. By means of the simulation measurement device and method, the area of the urine pit in the IR image can be quickly and accurately calculated, the automation degree is high, the device is simple and convenient to carry, and support is provided for the detection and analysis of urine emission in the dairy cattle farm.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring and image processing, in particular to a simulation measuring device and method for the area of ​​urine on the ground of a dairy farm, which is convenient for the NH of the dairy farm. 3 Calculation of emissions. Background technique [0002] In Europe, due to NH 3 Sedimentation leads to eutrophication and acidification of the environment, emission caps have been set to regulate NH 3 Emissions of harmful gases such as (UNECE, 1999. The 1999 Gothenburg Protocol to Abate Acidification. Eutrophication and Ground-level Ozone). However, in the actual breeding of dairy cows and other livestock and poultry, some areas of my country emit a large amount of NH 3 has resulted in an overload of the natural environment. a lot of NH 3 Emissions are caused by agricultural economic industries, a large part of which comes from dairy cows, hogs and other farming industries. A typical barn con...
