Description

technical field

[0001] The invention relates to a detection system and a detection method thereof, in particular to an inclusion dynamic detection system used in geological research and a detection method thereof. Background technique

[0002] At present, observation of inclusions is mainly realized through manual observation. Observers use microscopes to observe inclusion sheets (thin slices of rocks containing inclusions) to find moving objects. The existing technology has two biggest shortcomings. Disadvantage 1: inclusions are often extremely small, and it is difficult for the human eye to detect small moving objects, which are easy to miss during the observation process; Disadvantage 2: Due to the large magnification ratio of the microscope, the The observation area is small, so it takes a lot of time to observe the entire thin slice, which greatly consumes the time and energy of the observers. As time goes by, the observers consume a lot of energy and it is extremely ...

Examples

Embodiment 1

[0045] Such as figure 1 As shown, the inclusion motion detection system includes a digital microscope and a host computer 6 connected to the digital microscope, and an image acquisition head 1 and a motorized stage 3 are arranged on the digital microscope. The electric stage 3 is also provided with an electric motor and a motion control card 2, the electric motor is connected to the motion control card 2, and the electric motor is used to control the movement of the electric stage 3 in the X-axis and Y-axis directions. The control card 2 is connected with the host computer 6 through the data converter 5 . The image acquisition head 1 is arranged on the upper side of the digital microscope and is connected with the objective lens arranged on the digital microscope. The image acquisition head 1 is connected with a video acquisition card 4 and is connected with the host computer 6 through the video acquisition card 4 .

[0046] The host 6 is also provided with an alarm 7 .

Embodiment 2

[0060] Such as image 3 As shown, the single-area detection method using the inclusion motion detection system includes the following steps:

[0061] A', fix the sheet to be detected on the motorized stage at the initial position;

[0062] B', start the host, the host divides the observation area of ​​the slice and selects the area to be detected;

[0063] C', the image acquisition head collects images and sends them to the host through the video acquisition card; the images collected by the image acquisition head are transmitted to the host in the form of video streams;

[0064] D', the host computer compares the images in the observation area and judges whether there is a moving target in the observation area, and if there is a moving target in the observation area, then proceed to step E', otherwise directly proceed to step G'; the host first uses the functions in the OpenCV library to image The signal is preprocessed, and then the host performs background difference proc...
