布氏硬度机将一定直径的硬质合金压头施加试验力在试样上压出压痕后,由摄像头捕捉压痕,通过图像采集卡读取到计算机中,用图象处理软件对压痕进行处理,获得压痕边缘轮廓的拟合曲线,然后根据拟合曲线内的图像像素数,计算出压痕面积。根据布氏硬度试验原理,编写计算程序,根据压痕面积计算出材料的布氏硬度。并将结果显示在显示屏上。-Brinell hardness machine will be the diameter of the carbide pressure head test force applied on the pressure out of the sample after indentation, the indentation from the camera to capture, through image acquisition card reader to a computer with image processing software on the pressure marks are processed to obtain the fitting curve of the indentation edges, and then curve fitting the number of pixels within the image to calculate the indentation area. Brinell hardness test according to the principle of writing computer program to calculate the area under the indentation Brinell hardness materials. And the results shown on the display.
