Physical experiment instrument capable of performing visual analysis

The physical experiment instrument comprises a base, a light source plate is installed at the top end of the base, a calibration plate support is fixed to the top end of the light source plate, a calibration plate is installed on the calibration plate support, and a circular mark is arranged on the calibration plate; the industrial camera collects an image of the mark and sends the image to the upper computer; the upper computer compares the size of the image of the mark with the actual size of the mark, and the scaling of the image collected by the industrial camera is determined; the upper computer establishes an image coordinate system according to the scaling; the physical experiment device is mounted on the light source plate; in the process that the physical experiment device performs a physical experiment in front of the light source plate, the industrial camera synchronously collects a moving image of the physical experiment device and sends the moving image to the upper computer; and the upper comput
