Description

  The present invention relates to an inspection apparatus that inspects inspection objects such as vehicles and heavy equipment for construction that may be contaminated with radioactive substances.

  When moving vehicles and heavy construction equipment used for decontamination work out of the management area, control is performed to prevent radioactive materials adhering to the vehicle and heavy construction equipment from spreading outside the management area. Vehicles and heavy equipment for construction that are scheduled to leave the area are inspected for radioactive materials that exceed the prescribed dose.

However, the inspection object of the inspection apparatus 100 of the present invention is not limited to this, and other objects such as heavy equipment for construction. It can also be applied to.

  The imaging unit 30 captures an inspection target such as a vehicle and acquires image data. FIG. 2 is a diagram illustrating a state in which image data is acquired by such an imaging unit 30.

  The extraction unit 20 performs image analysis of the image data acquired by the imaging unit 30 and extracts dirt data relating to a dirt spot on the surface of an inspection object such as a vehicle. As the extraction unit 20, a processor that executes an image analysis program can be used. Note that conventional techniques can be used as appropriate for the image analysis processing and the image recognition processing in the extraction unit 20.

  FIG. 3 is a diagram for explaining the dirt data extraction process in the inspection apparatus 100 according to the embodiment of the present invention. FIG. 3A shows image data, and the extraction unit 20 recognizes vehicle dirt in the image data by image recognition. FIG. 3B shows the dirt data in the vehicle based on the image recognition as described above, which makes it possible to grasp where the dirt spot of the vehicle exists in the vehicle.

  In the inspection apparatus 100 according to the present invention, it is presumed that the contamination portion extracted by the extraction unit 20 has a high probability of attaching a radioactive substance. Therefore, the vehicle portion corresponding to the dirty portion of the dirty data extracted by the extraction unit 20 is inspected in more detail.

  The control unit 10 is a general information processing apparatus including an arithmetic unit such as a microprocessor, a rewritable memory such as a RAM, a non-rewritable memory such as a ROM, and the like, which is extracted by the extraction unit 20.

  The radiation sensor unit 50 detects a dose of radiation emitted from the inspection object and acquires detection data, and a GM tube survey meter, an ionization chamber survey meter, a scintillation survey meter, or the like can be used. .

  The radiation sensor unit 50 as described above is attached to a scanning unit 40 which is a stage (not shown) capable of moving in the XYZ directions shown in FIGS. 5 and 6. Based on a control signal from the control unit 10, the scanning unit 40 scans the radiation sensor unit 50 in the vicinity of the vehicle that is the inspection object.

  Moreover, the warning part 60 gives a warning by a sound and a display. When the radiation detection data from the radiation sensor unit 50 is a predetermined dose or more, the control unit 10 operates the warning unit 60 to give a warning.

In step S102, the extraction unit 20 extracts the dirt data relating to the dirt on the vehicle surface based on the image data.

  In step S103, the scanning unit 40 is driven, and scanning of the entire vehicle by the radiation sensor unit 50 is started.

In step S104, it is determined whether or not the part being scanned is a dirty part. If the determination in step S104 is NO, it is predicted that the radioactive material is less likely to be attached. Therefore, the process proceeds to step S105, where the scan speed of the radiation sensor unit 50 is a relatively fast first scan. Set to speed V ₁ . FIG. 5 shows the state of step S105.

On the other hand, if the determination in step S104 is YES, it is predicted that the site has a high probability that the radioactive substance is attached. Therefore, the process proceeds to step S106, and the scan speed of the radiation sensor unit 50 is the first scan speed. A second scanning speed V ₂ that is slower than V ₁ is set. FIG. 6 shows the state of step S105.

  In step S107, it is determined whether or not the detection data in the radiation sensor unit 50 indicates a predetermined dose or more.

  If the determination result of step S107 is YES, it will progress to step S108 and will operate the warning part 60. FIG.

  On the other hand, if the decision result in the step S107 is NO, the process advances to a step S109 to determine whether or not the entire vehicle has been scanned. If the determination in step S109 is NO, the process returns to step 104 and loops. If YES, the process ends in step S110.

  Since the inspection apparatus 100 according to the present invention controls the scanning speed of a dirty portion of an inspection object such as a vehicle or a heavy construction machine to be slower than the scanning speed of a portion other than the dirty portion of the inspection object, According to the inspection apparatus 100 according to the present invention as described above, it is unlikely that an inspection omission occurs, and the inspection time can be shortened.
