[0026] In step 104, a target equipment image in the target image is identified, and target equipment temperature information is output according to the temperature measurement information.

[0027] The embodiments of the present application are applicable to power equipment in which natural heat dissipation is used, such as cables, reactors, and other power equipment of conductors and insulators in which forced heat dissipation is not used.

[0028] The embodiment of the present application is applicable to detecting a variety of types of power equipment, and can be used to detect the surface temperature of the power equipment. The embodiment of the present application uses an infrared binocular camera head to capture an infrared image of the power equipment, performs infrared temperature measurement within the field of view of the infrared binocular camera head to obtain temperature measurement information within the field of view, performs calculations on the infrared image obtained within the field of view according to the triangular temperature measurement principle, determines depth information corresponding to the infrared image within the field of view, cuts the infrared image according to the depth information, obtains a target image within a preset depth range, identifies the target equipment image in the target image, determines the type of the target equipment, such as "reactor", and outputs temperature information of the target equipment according to the temperature measurement information corresponding to the target equipment.

[0029] By applying the technical solution of this embodiment, a triangulation operation is performed on the infrared image to obtain image depth information, and a target image within a preset depth range is divided from the infrared image, thereby reducing the influence of the background on the temperature judgment and improving the accuracy of temperature detection for power equipment.

[0030] The embodiments of the present application are more convenient for the operator and improve the accuracy of temperature detection for power equipment compared to methods that use handheld detection devices and two-dimensional images to detect temperature.

[0031] As a subdivision and development of the above embodiment, in order to illustrate the implementation process of this embodiment, another method for measuring the temperature of power equipment is provided, as shown in FIG. 2, the method includes the following steps:

[0032] In step 201, materials of electric power equipment are used to make an infrared binocular calibration plate, and the infrared binocular calibration plate is heated.

[0033] In step 202, the infrared binocular calibration plate is set at a plurality of different positions, and the infrared binocular calibration plate is photographed by an infrared binocular camera head to obtain a plurality of calibration images corresponding to the different positions. Infrared temperature measurement and radiation temperature measurement are performed on the preset temperature measurement points on the infrared binocular calibration plate, and the infrared temperature measurement and radiation temperature measurement temperatures of the preset temperature measurement points are obtained.

[0034] In step 203, parameter calibration is performed on the infrared binocular camera head based on the calibration image.

[0035] In step 204, a temperature difference between the infrared temperature measurement and the radiation temperature measurement is calculated, and the temperature measurement emissivity of the infrared binocular camera head is adjusted according to the temperature difference.

[0036] In step 205, an infrared image of the power equipment is captured by an infrared binocular camera head, and infrared temperature measurement is performed on an area within the viewing range of the infrared binocular camera head to obtain temperature measurement information.

[0037] In the embodiment of the present application, materials commonly used in power equipment are used to make an infrared binocular calibration plate. As shown in FIG. 3, the shape of the infrared binocular calibration plate includes a square or circular checkerboard grid. The infrared binocular calibration plate is supported by a rail bracket and can realize rotation with three degrees of freedom. The infrared binocular camera head, the interaction panel and the visualization screen are fixed to the operation platform and can also realize rotation with three degrees of freedom. The commonly used materials of the infrared binocular calibration plate include stainless steel, carbon steel, silicone rubber and ceramics, etc., and are coated according to the coating of the power equipment. Thus, after the parameters and temperature measuring emissivity of the infrared binocular camera head are determined using the calibration plate, the infrared binocular camera head can more accurately capture infrared images and perform infrared temperature measurement. Before the start of calibration, the infrared binocular calibration plate is uniformly heated, the infrared binocular calibration plate is set at a number of different positions, and the infrared binocular calibration plate is photographed by the infrared binocular camera head to obtain a number of calibration images corresponding to different positions. As shown in FIG. 4, infrared temperature measurement and radiation temperature measurement are performed on the preset temperature measurement points on the infrared binocular calibration plate, and the infrared temperature measurement and radiation temperature measurement temperatures of the preset temperature measurement points are obtained. A parameter calibration is performed on the infrared binocular camera head according to the calibration images. Then, the temperature difference between the infrared temperature measurement and the radiation temperature measurement temperature is calculated, and the temperature measuring emissivity of the infrared binocular camera head is adjusted according to the temperature difference value. The temperature measuring emissivity adopts an initial value of 0.9 and is adjusted with a step size of 0.02. When the difference value is increased five consecutive times by adjusting in the same direction, an adjustment is made in the opposite direction and the difference value is calculated at the same time. When the difference value is minimized, it is the optimal temperature measuring emissivity. The specific point can be specified in advance before calibration, for example, the corner point or the center point of the grid of the calibration plate is used, and the number is selected to be 10 or more.

[0038] In step 206, a triangulation operation is performed on the infrared image to determine depth information corresponding to the infrared image.

[0039] In step 207, a linked object identification range corresponding to the preset depth range is determined according to a preset linked object identification distance, where the preset linked object identification distance means that the depth range is adjusted slightly according to the connection status of the identified object / target within a preset depth distance range, so that the identified object / target is kept as completely as possible in the cut image.

[0040] In step 208, identify a target image within the target identification range, cut the infrared image according to the target image and the depth information, and obtain a target image including the target image and a preset depth range image.

[0042] In step 209, based on the temperature measurement information, a temperature normal linked object in the linked object image whose measured temperature is within a preset normal temperature range is identified.

[0043] In step 210, the temperature normal connected objects are removed from the target image.

[0044] Based on the temperature measurement information, temperature-normal linked objects in the linked object image whose measured temperatures are within a preset normal temperature interval are identified, and the temperature-normal linked objects are removed from the target image to facilitate providing input for target identification.

[0045] In step 211, the target facility image is identified by the left-eye infrared view or the right-eye infrared view of the target image.

[0046] In step 212, based on the temperature measurement information, temperature abnormality areas in the infrared image are identified, where the measured temperature is outside a preset normal temperature range.

[0047] In step 213, if the temperature abnormality area exists in the image of the target equipment, the temperature information of the target equipment is output.

[0048] The left-eye infrared view or the right-eye infrared view of the target image is used to identify the target equipment image, and it is determined that only one side of the view is used during the identification. According to the temperature measurement information, the temperature abnormality area in the infrared image, in which the temperature measurement temperature is outside the preset normal temperature range, is identified, and the temperature abnormality includes the temperature being too high or the temperature being too low. If the temperature abnormality area exists in the target equipment image, the target equipment temperature information is output, and the temperature abnormality area is the depth, height, length information of the abnormality position or the position of the isotherm. In the embodiment of the present application, when the emissivity is different for different materials, the different emissivities are adjusted accordingly to match the optimal temperature measurement emissivity, and the depth information is used to reduce the influence of the background on the temperature detection, thereby improving the accuracy of the temperature detection for the power equipment.

[0049] After step 205, the process further includes determining the depth corresponding to the temperature measurement information, correcting the temperature measurement information based on an infrared temperature measurement distance correction coefficient table including distance correction coefficients corresponding to different depths, obtaining target temperature information, i.e., the temperature value after temperature measurement and distance correction or abnormal temperature information including the abnormal temperature value which is the maximum value in the temperature range, and drawing a three-dimensional isotherm diagram based on the target temperature information and the depth corresponding to the target temperature information, to more intuitively express the target temperature information and the corresponding depth.

[0050] In addition, outputting the temperature information of the target equipment through the visualization screen includes reading historical temperature information, which is the previously measured temperature value or the maximum value of the temperature range of the target equipment, determining the temperature change trend of the target equipment, such as increasing, approaching or decreasing, based on the temperature information of the target equipment and the historical temperature information, adopting 0.5°C as the threshold value of the temperature change trend, generating and displaying infrared diagnosis abnormality text description information, which includes the target equipment information, the target equipment position information, the target equipment temperature information, the historical temperature information and the temperature change trend, and the stored text format is target equipment-target equipment position-target equipment temperature-history temperature-temperature change trend, which makes it easy for the detector to directly match the text.
