Determination of the size of rock granules in a bucket and on a conveyor

01/

Very small pellets indicate that extra explosives are spent on drilling and blasting - it's expensive.

The size of the rock pellets is an indicator of the efficiency of the entire mining process.

Too large granules reduce the performance of the bucket, because voids form in it. And they also require more processing time and can even break the crushing machine.

Why is it useful

02/

automation of the verification process

Employees do not have to evaluate the composition of the conveyor belt by eye – and this is additional time and qualifications:

acceleration and optimization of bucket/belt operation

How it works

03/

The data about this is transmitted to the customer

The system analyzes the video and highlights granules of too large size

Cameras are installed on the conveyor and bucket (if they are not already there)

The bucket is dark

Additional lighting and additional training of the model were needed to work in difficult visual conditions.

Solution

If the video quality was sufficient indoors, then it was more difficult to work "in the fields". The bucket is quite dark during the day, and often the work goes on at night.

Problem

Large mass of similar objects

Therefore, markup played an important role in the project — and we had to work with it.

Solution

There could be from 600 to 1000 objects in one picture, and they all look pretty similar. Besides, the conveyor belt is moving fast.
