基于Kinect传感器的羊体体尺测量系统
摘要
在基于机器视觉的羊体体尺测量中
当光线、背景等产生干扰时
彩色图像无法准确提取出羊体轮廓
且羊体站姿的变化也会造成测量误差。基于VS2010
Windows SDK搭建羊体测量系统
为解决背景干扰的问题
采用Kinect传感器获取现场羊体彩色和深度图像
将彩色与深度图像相结合提取羊体轮廓;结合深度信息建立羊体空间轮廓线拟合平面
并计算其与像平面夹角
进行体位站姿纠偏后得到羊体体尺数据。经过实验测试
相对误差在4.3%以内。
Abstract
In sheep body measurement based on machine vision
the color image can not extract sheep contour precisely because of light and background interference. Sheep ’s uncertain standing posture can also cause measurement error. In order to solve the problem of background interference
measurement system is built based on VS2010
Windows SDK
and Kinect sensor as the image acquisition device is used to acquire the sheep body color image and depth image. Sheep body contour is gained by the way of color and depth fusion. Sheep body space contour fitting plane is established based on depth information
and angle between image plane and fitting plane is calculated to solve the problem of standing posture effect. The test results show the relative error is within 4. 3 %.
