Detailed Description
The present invention is described below with reference to the drawings and the detailed description.
Referring to fig. 1, an underground coal mine early warning method based on image key information identification provided in an embodiment of the present application includes:
s101, acquiring key positions of underground coal mine monitoring equipment in the video monitoring image.
There are various monitoring devices in the coal mine, such as gas monitors, underground multi-channel seismometers, etc. The gas monitor can realize real-time monitoring of the concentration of the monitored gas, and the underground multichannel seismograph is an important device commonly used in underground three-dimensional seismic exploration of coal mines and is mainly used for measuring seismic wave parameters such as seismic wave speed, density and modulus of coal bodies of coal beds, so that the coal geological structure is evaluated and depicted, and comprehensive understanding of the mine geological structure is realized.
Under the general circumstances, the underground inspection personnel is required to acquire the monitoring data of the underground monitoring equipment regularly, and along with the popularization of the video monitoring technology, the underground camera can remotely acquire the display information of the display screen of various monitoring instruments. The underground camera is equipment which is frequently used when detecting narrow spaces such as underground shafts or caves, and can shoot factors which affect coal production safety, such as puzzled stratum changes, coal seam configurations and the like in the shafts.
In this embodiment, the shooting end of the downhole camera is directly aligned to the information display screen and the display lamp of various downhole monitoring devices, and then various downhole information monitored by the downhole monitoring devices can be directly obtained by shooting by the downhole camera. If the information display screen displays underground abnormal information and/or the display lamp is in an abnormal state, taking the position of the information display screen or the display lamp as the key position, and taking the shot image information as the key position information of underground monitoring equipment.
S102, cutting and preprocessing the video monitoring image according to the region corresponding to the key position to obtain a key sub-image.
For the key position information of the monitoring equipment obtained by the downhole camera, for most of the information in the image belongs to redundant information, the downhole safety information for alarming the monitoring equipment is not helpful. Therefore, in this embodiment, the information display screen and the display lamp area are cut to obtain an initial cut image, and the image information obtained after cutting is an image only including the information display screen and the display lamp.
Performing image amplification processing on the initial clipping image, and increasing the resolution of the initial clipping image in the amplification process; and splitting the information display screen area and the display lamp area in the amplified initial clipping image to obtain a first sub-image and a second sub-image. In order to obtain the text information in the information display screen more accurately, in this embodiment, the first sub-image is subjected to gray processing, so that the bottom plate of the display screen is white, and the display font is black, thereby realizing that the text can be recognized more clearly. For the display lamp in the second sub-image, there may be a problem that the display lamp of a part of the monitoring device is aged, so that the color of the display lamp is not obvious enough, and therefore, the saturation adjustment is performed on the color of the display lamp in the second sub-image, so that the display color of the display lamp is deepened. And after the first sub-image and the second sub-image are processed, the key sub-image is obtained by splicing the processed first sub-image and second sub-image.
S103, analyzing the image information displayed in the key sub-images, and generating early warning information by the analyzed content and the corresponding monitoring equipment information.
After the first sub-image and the second sub-image are processed in S102, the characters in the display screen in the finally obtained key sub-image are more prominently clear, and the color of the display lamp is also more clear. Based on the obtained key sub-image, in this embodiment, the display content of the information display screen in the key sub-image is obtained and a first field is generated, that is, the key text in the display screen is replaced in the form of a field. Since not all text contents are key information, in this embodiment, key content segments in the display content are determined; and screening the key content fragments from the display content to obtain the first field.
For display lamps, the underground monitoring equipment generally gives early warning of different grades for different dangerous degrees, and is particularly reflected in color. Therefore, in this embodiment, the second field is generated according to the risk level determined by the color of the display lamp, that is, the color of the display lamp and the corresponding level generate field information. Specifically, a third field is generated according to the risk level determined by the color of the display lamp; displaying the third field and the downhole position information of the corresponding monitoring equipment in the key sub-image in a text form to obtain an early warning image; and taking the early warning image as the early warning information.
For example, if the display light is red, then the second field corresponds to a "high level hazard signal, handle in time-! When the display lamp is yellow, the second field corresponds to the medium-level danger signal and timely processes-! By way of example only, the above is illustrative, and other warning meanings are possible for the color of the display lamp, and the corresponding second field is also presented at the same time.
After the first field and the second field information are obtained, the position of the corresponding monitoring device in the pit is also important, and in this embodiment, the content of the first field, the second field and the position information of the corresponding monitoring device in the pit is recombined to obtain the early warning information.
In the above embodiment, the first sub-image and the second sub-image are processed into field information to display the early warning information, and in another exemplary embodiment, the early warning information is displayed in the form of a picture.
In this embodiment, a third field is generated according to the risk level determined by the color of the display lamp; displaying the third field and the downhole position information of the corresponding monitoring equipment in the key sub-image in a text form to obtain an early warning image; and taking the early warning image as the early warning information.
Specifically, since the key sub-images obtained by stitching the first sub-image and the second sub-image are already very clear in text information in the first sub-image, only if the key sub-image is directly sent out, the display level of the display lamp needs to be determined. Therefore, in this embodiment, the risk level determined by the color of the display lamp in the second sub-image is directly converted into the third field, and then the third field is substituted for the second sub-image in the key sub-image, so that the second sub-image is converted from the image form of display single transmission to display the early warning information in the same text as the first sub-image.
It should be noted that, in this embodiment, when the third field and the downhole position information of the corresponding monitoring device are displayed in the key sub-image, the display font is the same as the display font of the information display screen area, that is, the display form is the same as that in the first sub-image.
S104, sending the early warning information to a ground control room for realizing underground early warning.
And after the early warning information is generated, carrying out priority group division on the early warning information according to the preset color grade and the color of the display lamp in the early warning information. If the same priority group contains a plurality of pieces of early warning information, the sending priority of the early warning information is determined according to keywords in the display content of the information display screen. And sending the early warning information according to the priority group and the sending priority.
