Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Firstly, a target detection process of an industrial camera is described in detail:
as shown in figures 1-3, the target format is mosaic of black and white, the number of the camera target mosaics is 9 multiplied by 9, for improving the precision, the first row of mosaics are 10mm multiplied by 10mm square blocks each, and the second row of mosaics are 9mm multiplied by 9mm square blocks each.
The measuring principle is consistent with a vernier caliper, the mosaics in odd rows of the target are 10mm each, and the mosaics in even rows are 9mm each. The built-in LED lamp of camera target for improve mark target luminance, the target is caught to the CCD industry camera of being convenient for, and the focus has been adjusted, and until CCD camera pixel and the first row of mosaic of target become the integral multiple relation, the formation of image at this moment can be according to camera pixel, the length of every pixel is calculated to the focus or according to the first row of every mosaic of target how many pixels, calculates the length of every pixel. According to the pixel length, the distance or length relation between the four targets in the same picture can be calculated.
Example 1
As shown in the figures 4-6 of the drawings,
a double-signal false alarm correction system for high formwork automatic detection is disclosed as 1-3 and comprises a data detection module, a comparison module, a storage module and a processing module, wherein the data detection module comprises a CCD industrial camera, an inclination angle sensor, a pressure sensor and a displacement sensor.
The CCD industrial camera is mounted on a high-profile, and the type is selected according to the height of the high-profile, so that the set targets, such as the four targets shown in fig. 2, can be seen in the camera field of view, and the four targets are distributed at the four corners of a rectangle.
The processing module is, for example, an upper computer and is used for comprehensively judging signals and sending out an alarm instruction;
a storage module is coupled to the industrial camera and a comparison module is capable of storing target data collected by the industrial camera, wherein the storage module is coupled to the processing module for use by the processing module in its data.
The comparison module is connected with the storage module and can compare target data collected by the industrial camera in the storage module with threshold data set in the storage module to generate a first judgment signal, and the comparison module is connected with the processing module and transmits the first judgment signal to the processing module;
the inclination angle sensor, the pressure sensor and the displacement sensor are all connected with the processing module and transmit second judgment signals acquired by the processing module to the processing module, so that the processing module sends out an alarm instruction according to the first judgment signals and the second judgment signals.
Specifically, the industrial camera transmits the collected target data to the storage module through the data transmission terminal DTU.
As can be seen from fig. 6, compared to fig. 5, the target distance from the top left corner target to the top right corner is reduced by 2 pixels, and the target distance from the top left corner target to the bottom left corner is reduced by 2 pixels, which can be obtained according to the industrial camera model selection:
comparing the length values of the four targets with the length values of the initial position state (shown in figure 5) to obtain a variation, comparing the variation with a threshold, and if the variation exceeds the threshold and the first judgment signals sent by the sensors are effective, sending an alarm instruction by the processing module.
A specific use process of this embodiment is as follows:
before concrete pouring, a CCD industrial camera is controlled to collect 4 clear targets, the targets are set to be in an initial state, the target at the upper left corner is used as a reference point, the length from the target point to other 3 targets is calculated, and the length is recorded. After concrete begins to pour, the control triggers that CCD industrial camera continuously gathers the mark target photograph and saves through storage module, calculate the distance of mark target datum point to other three datum points, compare initial state through comparison module, see whether the distance of target datum point to other three datum points changes, if the length change surpasses and predetermines the threshold value, send the effectual instruction of second judgement signal to processing module, processing module retrieves tilt angle sensor this moment, pressure sensor, whether displacement sensor takes place early warning and warning at same time data, and then it is true to report to the police or the wrong report to the police to obtain tilt angle sensor, pressure sensor, displacement sensor data.
Example 2
A double-signal false alarm correction system for high formwork automation detection is disclosed as 7. on the basis of embodiment 1, the embodiment is integrated and provided with a plurality of CCD industrial cameras, and the CCD industrial cameras are all connected to a processing module.
In order to facilitate communication, a plurality of CCD industrial cameras can also be connected by adopting a router module so as to reasonably distribute the IP of each CCD industrial camera.
According to the embodiment, a plurality of CCD industrial cameras can be configured according to the area size of the high formwork, so that more area coverage is achieved.
According to the characteristic of long alarm period of high formwork occurrence, according to the trigger frequency, the comparison module is arranged to continuously collect a certain number of times that target distance changes and exceeds an alarm value, then the effective instruction of the first judgment signal is sent to the processing module, when the processing module does not receive the effective instruction of the first judgment signal, the measured value of the tilt sensor, the pressure sensor and the displacement sensor exceeds the alarm value and the second judgment signal is sent effectively, and when false alarm processing is carried out, the mode is favorable for the false alarm occurrence of the sensors for point monitoring due to the problems of vibration rods, sensor precision and the like.
Of course, if the processing module receives the instruction that the first determination signal is valid, the processing module may process the second determination signal as a false alarm if the processing module has the instruction that the second determination signal is valid.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art can make some modifications without departing from the scope of the invention, i.e. all equivalent modifications made according to the invention are intended to be covered by the scope of the invention.
