Remote collaborative prospecting system based on AR augmented reality technology and data mining

technical field

The invention relates to an unknown ore recognition system based on augmented reality technology, in particular to an unknown ore recognition system for distinguishing friction sparks on the surface of unknown ores based on graphic recognition technology.

Background technique

With the continuous growth of ore mining, there are fewer and fewer high-quality mineral deposits, and it is difficult to find standard ores like textbook photos, and more are low-grade associated or mixed ores, which has caused relatively large exploration for front-line prospectors. Difficulties. Conventional monitoring methods, such as spectroscopy or laboratory analysis, generally require carrying sophisticated instruments, or need to bring samples back to the rear laboratory in order to obtain a preliminary judgment.

Aiming at the above problems, the present invention develops a remote collaborative prospecting system based on AR augmented reality technology and data mining, including:

Rotary grinding equipment for rubbing against the surface of the unknown ore to be detected; said equipment has standardized dimensions;

The video acquisition unit acquires the video image of the sparks generated by the high-speed friction between the rotating grinding wheel and the surface of the unknown ore through a filter;

The video recognition unit processes the video image to obtain the corresponding line image of the sparks in each frame image; analyzes the characteristics of the spark bundle in the line image, and the characteristics of the spark bundle include at least the number, length, radian and color of the streamline, and the composition of the spark The number and characteristics of the bursts at the nodes of the bouquet and the shape of the root, middle and tail of the bouquet, also including the number of sparks contained on the streamline;

A database, which stores the ore type data corresponding to the characteristics of the spark bundle;

When in use, the processing unit compares the characteristics of the spark beams obtained by analysis with the characteristics of the spark beams in the database, and gives the specific data of the ore currently to be detected; the display unit outputs the results.

When the database does not record the characteristics of the current sparks, and the judgment conclusion cannot be given, the sparks close to the characteristics are found in the database by analyzing the characteristics, and a judgment suggestion is given.

As a preferred embodiment, the rotary grinding device also has a pressure monitoring module that monitors the pressure value of the rotary grinding device in contact with the surface of the unknown ore;

During the grinding process, the pressure value is monitored, and when it exceeds the set value range, an alarm is issued.

As a preferred embodiment, the camera of the above-mentioned video acquisition unit has a filter.

Due to the adoption of the above technical solution, a remote collaborative prospecting system based on AR augmented reality technology and data mining disclosed in the present invention is based on mature image recognition technology to identify the video features of sparks generated during the metal grinding process, with low cost and mature technology , very suitable for large-scale promotion and use.
