Problems solved by technology

For character image recognition in underground mines, general character recognition algorithms cannot be used, and traditional digital image processing technology cannot adapt well to various complex environments. For example, low light intensity in underground mines will affect the imaging effect, and serious underground dust will affect the surface characteristics of characters.

Embodiment

[0034] The image acquisition device of this embodiment uses Nvidia TX2 artificial intelligence edge computing device, which has a size of 50 mm x 87 mm, a small size, and a power consumption of only 7.5 watts. The electricity is low, and those not specified in the method are all conventional techniques.

[0035] Specific steps are as follows:

[0036] 1) Install a character plate every 20 meters next to the railroad track in the mine. The size of the character plate is similar to the size of a car license plate. Each license plate is printed with 8 characters, and a character plate must be installed at each fork. And record the position of each numbered rail in the database system, which is installed in the production dispatching center;

[0037] 2) Install the image acquisition equipment on the UAV vehicle under the mine for image acquisition. A total of 6,000 underground character images were collected, of which 5,000 were used to train the network model and 1,000 were used t...

Abstract

The invention provides a method for obtaining the position of mine underground equipment based on character image intelligent identification, and the method comprises the steps: installing a pluralityof character boards beside an underground rail at intervals, marking a plurality of characters on each character board, and recording the rail position corresponding to each character number in a database of a production scheduling center; installing image acquisition equipment on the unmanned aerial vehicle under the mine, and acquiring all character images marked on the corresponding characterboards during driving; sending the acquired image to a U-Net network for detection; detecting an image with eight characters in the image; segmenting the image into eight non-overlapping sub-images, wherein each sub-image contains one character; after convolution operation and down-sampling operation, performing classification and identification to obtain corresponding character values and credible values, and transmitting the character value corresponding to the position with the maximum credible value to a production scheduling center in real time through a wireless network, so that the unmanned aerial vehicle can be accurately positioned underground, and industrial and automatic mining and transportation production requirements are met.

Description

technical field [0001] The invention relates to a method for obtaining the location of mine underground equipment, in particular to a method for obtaining the location of mine underground equipment based on character image intelligent recognition, and belongs to the technical field of character image recognition.
