  However, the following two-dimensional radiation thermometer disclosed by the applicant also has the following problems to be improved. That is, in this two-dimensional radiation thermometer, a frame-shaped temperature display mark is superimposed on the captured image, so that the shape of the measurement target can be easily grasped, and the temperature of each part of the measurement target can be accurately grasped. On the other hand, the frame-shaped temperature display mark is somewhat inconspicuous compared to the filled temperature display mark, so it is somewhat difficult to easily grasp the temperature distribution of the measurement object, and this point should be improved. Yes.

  The present invention has been made in view of such problems, and a thermometer capable of simultaneously and accurately grasping the temperature of each part of the measurement object and easily grasping the temperature distribution of the measurement object. The main purpose is to provide.

In this case, in the present invention, the "temperature distribution equivalently Cascade is displayed on the captured image an image" that is displayed as if the temperature distribution image on the captured image is visually recognized overlapping means. Therefore, the captured image may be displayed on the temperature distribution image, or both images may be displayed without actually superimposing the temperature distribution image and the captured image. Further, in the display control, the display control unit displays the captured image equivalently on the temperature distribution image on the display unit, and displays a part of the captured image (of the above-described temperature distribution image).

As a result, it is possible to accurately and easily grasp which part of the measurement object is the number of times. In addition, by continuing this display control for a predetermined time, it is possible to avoid a situation where there is an area where the temperature distribution image is not always displayed for displaying the captured image. Distribution can be displayed. For this reason, compared with a configuration in which a temperature distribution image in which frame-shaped temperature display marks are arranged is overlaid on a captured image, the temperature distribution image can be displayed more easily and as a result, the temperature distribution of the measurement object can be easily grasped. Can be made. Therefore, according to this thermometer, it is possible to simultaneously and accurately grasp the temperature of each part in the measurement object and easily grasp the temperature distribution of the entire measurement object.

According to the thermometer as set forth in claim 3, the temperature distribution in which the display control unit changes the display color corresponding to the detected temperature for each predetermined area and arranges the temperature display images having the shape corresponding to each predetermined area. By displaying the image and performing display control with a region corresponding to at least one temperature display image as a partial region, a part of the captured image is displayed in units of temperature display image, and thus is indicated by the temperature display image. As a result of further clarifying the correspondence between the temperature and the captured image of the part corresponding to the temperature display image, it is possible to more accurately and easily grasp the temperature of the measurement object of the part corresponding to the part. .

According to the thermometer according to claim 7 , the display control unit selects the next partial area every time the predetermined time interval elapses, so that the partial area is regularly moved at the constant time interval. Therefore, it is possible to more easily guess the shape of the measurement object based on the captured image that is displayed in a fragmentary manner by the movement of a partial region.

According to the thermometer of claim 8 , the storage unit stores time data indicating the time interval set by the operation of the second operation unit, so that the display processing interval is set by operating the second operation unit. Thus, the moving speed of some areas can be arbitrarily set according to preference.

  The best mode of a thermometer according to the present invention will be described below with reference to the accompanying drawings.

  A two-dimensional radiation thermometer 1 shown in FIG. 1 is a non-contact type temperature measuring device as a thermometer according to the present invention, and a temperature distribution image 12 showing a temperature distribution of a measuring object is imaged of the measuring object. The measurement result image G (both see FIG. 5) can be displayed so as to overlap the image 11 equivalently. As shown in FIGS. 1 to 3, the two-dimensional radiation thermometer 1 includes a temperature detection unit 2, an imaging unit 3, a display control unit 4, a display unit 5, a storage unit 6, an operation unit 7, and a control unit 8. It is prepared for.

  As shown in FIG. 3, the temperature detection unit 2 includes a sensor array 2a, an optical system 2b, and a signal processing circuit 2c. The sensor array 2a includes, for example, 64 temperature sensors (for example, infrared sensors) arranged in a matrix of 8 rows and 8 columns, and detects the temperature of the measurement object in a non-contact manner to detect a sensor signal Ss. Is output. In this case, each temperature sensor has a partition area (predetermined in the present invention) in which the area to be measured (for example, the measurement area A1 shown in FIG. 7) is partitioned by the same array pattern (matrix of the same matrix) as the array pattern of the temperature sensor. The temperature of each region is detected individually. The optical system 2b collects infrared rays on the sensor array 2a. The signal processing circuit 2c performs signal processing on the sensor signal Ss output from the sensor array 2a and outputs temperature data Dt indicating the temperature (detected temperature) of the measurement object.

  The imaging unit 3 includes a photoelectric conversion element (C-MOS element or CCD). In addition, the imaging unit 3 controls the measurement object (the wall 21 and the spherical body shown in the figure) in the imaging area (for example, the imaging area A2 shown in FIG. 7) including the measurement area A1 according to the control of the control unit 8. 22) and image data Dg is output.

  The display control unit 4 generates the display signal Sh based on the imaging data Dg output from the imaging unit 3 in accordance with the control of the control unit 8, thereby obtaining the captured image 11 of the measurement object as illustrated in FIG. 4. It is displayed on the display unit 5. In addition, the display control unit 4 generates the display signal Sh based on the temperature data Dt output from the temperature detection unit 2 and the imaging data Dg output from the imaging unit 3, so that FIGS. As shown, the temperature distribution image 12 of the measurement object is equivalently superimposed on the captured image 11 of the measurement object, and the measurement result image G is displayed on the display unit 5. In this case, the temperature distribution image 12 is an image showing the temperature distribution of the measurement object, and is filled with different display colors corresponding to the detected temperatures of the respective divided areas in the measurement area A1, and Rectangular temperature display marks M (temperature display images in the present invention) corresponding to the respective divided areas are arranged in a matrix (mosaic) pattern in the same pattern as the infrared sensor array pattern. In other words, the partition area is a rectangular area corresponding to the shape of the temperature display mark M on the measurement area A1.

  Further, when the partial display mode described later is selected by operating the operation unit 7, the display control unit 4 partially displays the captured image 11 that is hidden by the superposition of the temperature distribution images 12 (temperature distribution image 12 Is partially hidden), that is, a partial display process (display control in the present invention) is performed in which the captured image 11 is displayed so as to be visible through a part of the temperature distribution image 12 equivalently. To do. Specifically, as shown in FIGS. 6 and 8 to 10, the display control unit 4 displays the temperature distribution image 12 excluding a part of the region Ap (that is, part of the region Ap in the temperature distribution image 12. Display control for stopping the display for a predetermined time) and displaying the captured image 11 of the portion corresponding to the area Ap in the area Ap is performed while moving the area Ap (changing the position of the area Ap). In this case, the display control unit 4 executes the display control with the region corresponding to one or more temperature display marks M as the region Ap described above.

  For example, the display unit 5 includes a liquid crystal monitor in which a color liquid crystal panel and a backlight are packaged, and displays various images according to the control of the display control unit 4. The storage unit 6 counts the number of temperature display marks M corresponding to the region Ap that is excluded from display (stops display) in one display process in the partial display process executed by the display control unit 4 (hereinafter referred to as “this”). Quantity data Dn indicating the number of temperature display marks M) is also stored. In addition, the storage unit 6 stores time data Dp indicating a time interval for moving the region Ap described above in the partial display process (hereinafter, this time interval is also referred to as “display process interval”). The operation unit 7 corresponds to the first operation unit and the second operation unit in the present invention, and for setting the measurement start key 71 for starting measurement, the number of display stops, and the display processing interval, as shown in FIGS. And a number of operation keys such as a partial display key 73 for executing a partial display process. The control unit 8 controls operations of the temperature detection unit 2, the imaging unit 3, the display control unit 4, and the like. Further, when the display stop number and the display processing interval are set by the key operation of the operation unit 7, the control unit 8 stores the quantity data Dn and the time data Dp corresponding to the set values in the storage unit 6.

  Next, a temperature measurement method for measuring, for example, the temperature of the wall 21 and the spherical body 22 as the measurement object shown in FIG. 7 using the two-dimensional radiation thermometer 1 will be described with reference to the drawings.

  First, the power source of the two-dimensional radiation thermometer 1 is turned on, and then, as shown in FIG. 7, the back side of the two-dimensional radiation thermometer 1 in which the temperature detection unit 2 and the imaging unit 3 are disposed (in FIG. 2) The front side of the sheet is opposed to the wall 21 and the spherical body 22. At this time, the imaging unit 3 images the wall 21 and the spherical body 22 in the imaging area A2, and outputs imaging data Dg. Subsequently, the display control unit 4 generates a display signal Sh based on the imaging data Dg output from the imaging unit 3 and outputs the display signal Sh to the display unit 5. Thereby, as shown in FIG. 4, the captured image 11 of the wall 21 and the spherical body 22 is displayed on the display unit 5.

  Next, the measurement start key 71 of the operation unit 7 is operated. In response to this, the control unit 8 causes the temperature detection unit 2 to start temperature measurement. At this time, the sensor array 2a of the temperature detection unit 2 detects infrared rays from the wall 21 and the spherical body 22 collected by the optical system 2b, and outputs a sensor signal Ss to the signal processing circuit 2c. In addition, the signal processing circuit 2c performs signal processing on the sensor signal Ss output from the sensor array 2a, and outputs temperature data Dt indicating the temperature of the wall 21 and the spherical body 22.

  In this case, the temperature data Dt is output in association with the temperature corresponding to the infrared rays detected by each infrared sensor of the sensor array 2a and the arrangement position of the infrared sensor that detected the temperature. In response to this, the display control unit 4 determines the display colors of the 64 temperature display marks M constituting the temperature distribution image 12 based on the temperature data Dt output by the temperature detection unit 2. Next, the display control unit 4 generates a display signal Sh for displaying the measurement result image G by superimposing the temperature distribution image 12 in which the temperature display marks M are arranged in a matrix on the captured image 11 to display the display unit 5. Output to. Thereby, as shown in FIG. 5, the measurement result image G is displayed on the display unit 5.

  Here, since the temperature distribution image 12 is composed of filled temperature display marks M, the temperature distribution can be grasped at a glance. On the other hand, since the captured image 11 is hidden by the temperature distribution image 12, it is difficult to grasp the shapes of the wall 21 and the spherical body 22, and the correspondence between each temperature display mark M and each part of the measurement object is unclear. In addition, it is difficult to determine how many parts of the wall 21 and the spherical body 22 are.

  In this case, the two-dimensional radiation thermometer 1 can execute partial display processing for partially displaying the captured image 11 hidden by the temperature distribution image 12. When this partial display processing is executed on the two-dimensional radiation thermometer 1, first, the number of display stops is set to 5 for example by operating the numeric key 72 of the operation unit 7 and the display processing interval. Is set to 0.5 seconds, for example. In response to this, the control unit 8 generates quantity data Dn and time data Dp corresponding to the set values and stores them in the storage unit 6. Next, the partial display key 73 of the operation unit 7 is operated. At this time, the display control unit 4 executes a partial display process according to the control of the control unit 8.

  In this partial display processing, the display control unit 4 displays the temperature distribution image 12 excluding the partial area Ap (stops display of the partial area Ap in the temperature distribution image 12 for a predetermined time) and also displays the area Ap. The display control for displaying the captured image 11 of the part corresponding to is performed in the region Ap while moving the region Ap. Specifically, the display control unit 4 first specifies the display stop number (in this case, 5) based on the quantity data Dn stored in the storage unit 6, and selects from among the 64 temperature display marks M. Five temperature display marks M are selected at random. Subsequently, the display control unit 4 displays the display signal Sh for displaying the measurement result image G by superimposing the temperature distribution image 12 excluding each region Ap corresponding to the selected temperature display mark M on the captured image 11. Based on the data Dt and the imaging data Dg, it is generated and output to the display unit 5. Thereby, as shown in FIG. 6, the measurement result image G is displayed on the display unit 5.

  Next, the display control unit 4 specifies a display processing interval (in this case, 0.5 seconds) based on the time data Dp stored in the storage unit 6, and moves each area Ap when the display processing interval elapses. Let Specifically, the display control unit 4 randomly selects five temperature display marks M from among the 64 temperature display marks M, and subsequently executes display control similar to the above. Thereby, as shown in FIG. 8, the measurement result image G in which the region Ap has moved is displayed on the display unit 5. Next, each time the display processing interval elapses, the display control unit 4 randomly selects five temperature display marks M again and moves each region Ap, and displays the same as above. Execute control. As a result, as shown in FIGS. 9 and 10, a part of the region Ap in the temperature distribution image 12 moves at every display processing interval, and the captured image 11 is displayed so as to transmit the part corresponding to the region Ap. Is done. For this reason, a part of the captured image 11 hidden by the temperature distribution image 12 can be visually recognized. In this case, when the partial display process is continuously executed for a predetermined time and the region Ap moves a plurality of times, as shown conceptually in FIG. 11, the wall 21 is based on the captured image 11 displayed in pieces during that time. And the shape of the spherical body 22 can be easily estimated. For this reason, the correspondence relationship between each temperature display mark M and each part of the measurement target is clarified, and it is possible to accurately and easily grasp which part of the measurement target is the number of times.

  In addition, when the partial display process is continuously performed for a predetermined time and the region Ap moves a plurality of times, a situation in which the temperature distribution image 12 is not always displayed for displaying the captured image 11 is avoided. The temperature distribution can be displayed using the entire region of the temperature distribution image 12.

  Thus, in the two-dimensional radiation thermometer 1, when the display control unit 4 displays the temperature distribution image 12 and the captured image 11 on the display unit 5 in an overlapping manner, one of the temperature distribution images 12 is equivalently displayed. Display control (partial display processing) for displaying the captured image 11 through the region Ap so as to be visible is executed while moving the region Ap. For this reason, for example, even if the temperature distribution image 12 is composed of the filled temperature display marks M, a part of the captured image 11 hidden by the temperature distribution image 12 is displayed while moving its position. Therefore, by continuing this display control for a predetermined time, the shape of the measurement object can be easily estimated based on the captured image 11 displayed in pieces during that time. As a result of the clear correspondence with the temperature display mark M (detected temperature), it is possible to accurately and easily grasp which part of the measurement object is the number of times. In addition, by continuing this display control for a predetermined time, it is possible to avoid a situation where there is an area where the temperature distribution image 12 is not always displayed for displaying the captured image 11. Can be used to display the temperature distribution. For this reason, the temperature distribution image 12 can be easily recognized and displayed as compared with the configuration in which the temperature distribution image in which the frame-shaped temperature display marks are arranged is superimposed on the captured image. It can be grasped. Therefore, according to the two-dimensional radiation thermometer 1, accurate and easy grasping of the temperature of each part in the measurement object and easy grasping of the temperature distribution of the entire measurement object can be realized at the same time.

  Further, according to the two-dimensional radiation thermometer 1, the display control unit 4 changes the display color according to the detected temperature for each divided area, and the temperature display mark M having a shape corresponding to each divided area. Since the arrayed temperature distribution image 12 is displayed and display control is executed with the region corresponding to at least one temperature display mark M as the region Ap, a part of the captured image 11 is displayed in units of the temperature display mark M. As a result of further clarifying the correspondence between the temperature indicated by the temperature display mark M and the captured image 11 of the portion corresponding to the temperature display mark M, the temperature of the measurement object at the part corresponding to the portion can be further increased. It can be grasped accurately and easily.

  Moreover, according to this two-dimensional radiation thermometer 1, since the temperature distribution image 12 is comprised by the filled temperature display mark M, each temperature display mark M can be made conspicuous, Therefore The temperature distribution of a measurement object is obtained. It can be grasped at a glance.

  Further, according to the two-dimensional radiation thermometer 1, the display control unit 4 executes display control with the region Ap corresponding to the number of temperature display marks M set by the operation of the operation unit 7 as the region Ap. By operating the unit 7 and setting the number of temperature display marks M, the size of the region Ap can be arbitrarily set according to the size of the measurement object.

  Further, according to the two-dimensional radiation thermometer 1, the shape of the measurement object due to the movement of the region Ap is shifted by moving the region Ap to a position randomly selected by the display control unit 4. The situation where it is difficult to grasp can be avoided.

  Further, according to the two-dimensional radiation thermometer 1, since the display controller 4 moves the region Ap at a constant display processing interval, the region Ap moves regularly at a constant time interval. The shape of the measurement object based on the captured image 11 displayed in pieces by movement can be estimated more easily.

  Further, according to the two-dimensional radiation thermometer 1, the display control unit 4 moves the region Ap at the display processing interval set by the operation of the operation unit 7. By setting, the moving speed of the region Ap can be arbitrarily set according to preference.

  In addition, this invention is not limited to said structure. For example, the display control for equivalently transmitting the partial area Ap of the temperature distribution image 12 and displaying the captured image 11 so as to be visible is described. However, the captured image 11 is equivalently displayed on the temperature distribution image 12. And a part of the captured image 11 (a predetermined region of the captured image 11 that overlaps with a region other than the partial region Ap of the temperature distribution image 12 described above). Display control that allows the temperature distribution image 12 to be displayed in a visible manner (that is, display control that equivalently transmits the partial area Ap in the temperature distribution image 12 and displays the captured image 11 so as to be visible). It can also be done.

  Moreover, although the example which displays the part of the captured image 11 corresponding to the area | region Ap for five temperature display marks M in one display control was mentioned above, it is not limited to this, Arbitrary number of temperature display marks M Display control can be executed with the area corresponding to the area Ap as the area Ap. In addition, as shown in FIG. 12, display control is executed with the region Ap corresponding to one row (or a plurality of rows) of temperature display marks M in the temperature distribution image 12 as the region Ap, and the region Ap for the row is moved up and down. A configuration in which display control is repeated while sequentially moving in the direction can also be employed. According to this configuration, for example, when measuring the temperature of a horizontally long measurement object, the shape of the measurement object can be grasped in a short time. Further, as shown in FIG. 13, display control is executed with the region Ap corresponding to one column (or a plurality of columns) of the temperature display mark M in the temperature distribution image 12 as the region Ap, and the region Ap for the column is left and right. A configuration in which display control is repeated while sequentially moving in the direction can also be employed. According to this configuration, for example, when measuring the temperature of a vertically long measurement object, the shape of the measurement object can be grasped in a short time.

  Further, the configuration for displaying the temperature distribution image 12 configured by arranging the rectangular temperature display marks M in a matrix is described above. However, a temperature display image having an arbitrary shape (for example, a polygonal shape such as a triangle or a pentagon) can be displayed. It is also possible to employ a configuration for displaying an arrayed temperature distribution image. Further, the configuration in which the display control unit 4 moves the region Ap at regular time intervals has been described. However, a configuration in which the timing for moving the region Ap is instructed by the operation of the operation unit 7 may be employed. A configuration in which the movement position of the region Ap is designated by the operation of the operation unit 7 can also be adopted. Moreover, the structure of the temperature detection part 2 is not limited to the structure which detects detected temperature by non-contact, It can comprise arbitrarily. For example, a configuration in which a probe is brought into contact with a measurement object to detect a detected temperature can be employed. A configuration in which the captured image 11 and the measurement result image G are displayed on an external monitor can also be employed.
