Problems solved by technology

At present, the main measurement method is to measure with a vernier caliper and a tape measure according to the industry standard "Poultry Production Performance Terminology and Measurement and Statistics Methods" issued by China in 2004. The unit is in centimeters, and the measured value is taken to one decimal place. When measuring live poultry, the measurement is often inaccurate due to the difficulty of fixing and the sliding properties of the subcutaneous tissue, which in turn leads to large differences between the same body measurement values ​​measured by different fixing methods and measuring personnel for the same individual. In addition, the traditional waterfowl body size measurement method is difficult to measure and select each individual due to its high work intensity, and this method is also likely to cause a decline in the production capacity of the measured group because it stimulates the poultry. A more objective, rapid and accurate measurement method is the basis for poultry body size selection

Embodiment 1

[0032] Embodiment 1——Taihu goose body measurement:

[0033] 1. Calculation of the calibration ratio between the side view and the top view of the measurement individual: the measured lengths of the side view and top view reference pictures of the measurement individual are 5.6cm and 4.1cm respectively, and the actual length of the reference object in the two pictures is 15cm, thus According to formula (1), the collation ratios of the side view and top view of the individual are 2.67857 and 3.62854, respectively.

[0034] 2. Determination of the measured value of individual body size pictures: use the measurement tool to measure the distance from the first thoracic vertebra to the front edge of the keel, the front section of the keel to the end of the keel, and the distance between the upper tibial joint and the third and fourth toes in the side picture of the waterfowl individual in sequence, and substitute The diameter of the middle part of the shin and the length of the top ...

Embodiment 2

[0038] Embodiment 2——Shaoxing shelduck duck body size measurement:

[0039] 1. Calculation of the calibration ratio between the side view and the top view of the measurement individual: the measured lengths of the side view and top view reference pictures of the measurement individual are 5.5cm and 4.2cm respectively, and the actual length of the reference object in the two pictures is 15cm, thus According to formula (1), the collation ratios of the side view and top view of the individual are 2.72727 and 3.57143, respectively.

[0040]2. Determination of the measured value of the individual body size pictures: use the measuring tool to measure the distance from the first thoracic vertebra to the front edge of the keel, from the front section of the keel to the end of the keel, from the upper tibial joint to the third and fourth toes in the side picture of the waterfowl individual in sequence, and substitute The diameter of the middle part of the shin and the length of the bac...

Abstract

A method for measuring the size of a waterfowl body using a picture, comprising the following steps: 1) a picture scale calibration step; 2) a picture body size measurement step; and 3) a step of conversion between a picture measurement value of an individual body size and an actual measurement value of the individual body size. The beneficial effects of the present invention mainly lie in: 1, the measurement of the waterfowl body size data is more objective, and the diversity of measurement results caused by difference in measurement point cognition can be avoided by measuring the waterfowl body size using a picture; 2, human resources are saved; and 3, the body size measurement result is more accurate.

Description

technical field [0001] The invention relates to poultry body size measurement, in particular to water fowl, duck and goose body size measurement technology, which is suitable for water fowl body size measurement. Background technique [0002] Body size measurement is a very important part of poultry breeding work, because body size can not only reflect the meat and egg production performance of individuals to a certain extent, but also an important symbol for the difference between different breeds. At present, the main measurement method is to measure with a vernier caliper and a tape measure according to the industry standard "Poultry Production Performance Terminology and Measurement and Statistics Methods" issued by China in 2004. The unit is in centimeters, and the measured value is taken to one decimal place. When measuring live poultry, the measurement is often inaccurate due to the difficulty of fixing and the sliding properties of the subcutaneous tissue, which in t...
