In addition, the fire truck is equipped with a vehicle control PC 320 for controlling various devices of the vehicle, and using the vehicle control PC 320 to control the temperature for coloring in the image reprocessing PC 200 by wires 1. Can be set.

In the command vehicle, the image displayed through the command vehicle monitor 300 may be used to save lives.

FIG. 2 is a block diagram illustrating an example of the infrared camera shown in FIG. 1.

The infrared camera 100 may include an image input unit 102, an A / D converter 104, a control unit 108, an image compression unit 110, a power supply unit 106, an RF transmitter 112, and a memory 109. Can be.

The image input unit 102 detects a light signal of the surrounding image and outputs it as a voltage signal. The image input unit 102 may use a conventional CCD.

The A / D converter 104 converts an analog voltage signal output from the image input unit 102 into a digital signal, and the digital signal is input to the controller 108.

The controller 108 functions to process the digital signal and output image data. First, the controller 108 stores the digital signal output from the A / D converter 104 in the memory 109.

In addition, the control unit 104 encodes the image data by using the image compression unit 110 to compress the video, and compresses the image data by wirelessly transmitting the image reprocessing PC through the RF transmitter 112. Transmit to 200.

In addition, since the infrared camera 100 must be operated independently without being connected to the outside, the infrared camera 100 is provided with a power supply unit 106 such as a battery and a charging circuit, which is built in the infrared camera and supplies power.

The infrared camera 100 may be connected to a cable (not shown) to supply power through the cable, and image data may be transmitted to the image reprocessing PC 200 by wire through a cable. In this case, the infrared camera 100 If the fire is close to the fire, there is a risk that the cable will burn or be melted by heat.

In order to prevent this, a cable may be embedded in the fire hose and connected to the infrared camera 100, but installation is difficult and additional cost is generated.

Therefore, it is preferable to provide the power supply 106 and the RF transmitter 112 separately inside the infrared camera.

3 is a block diagram illustrating an example of the image reprocessing PC shown in FIG. 1.

As illustrated, the RF receiver 201, the image restorer 202, the controller 203, the memory 204, the reprocessing unit 205, and the RF transmitter 206 may be included.

Since the image data input through the RF receiver 201 is in a compressed state, it cannot be displayed on the monitor 210 as it is.

The image reconstruction unit 202 decodes the compressed image data input through the RF receiver 201 to reconstruct the original image, and the reconstructed image data is input to the control unit 203.

The control unit 203 reprocesses the image data through the reprocessing unit 205 and stores the reprocessed image data in the memory 204.

As described above, the infrared camera 100 senses a thermal wavelength emitted by a specific frequency according to temperature for each object and displays it as an image according to a temperature distribution.

When the image is displayed on the monitor 210 in this state, the low temperature image is clearly displayed, but the high temperature image is not clearly displayed.

Therefore, the correction of the inclination of the image distribution level proportional to the temperature distribution to a high temperature should be performed. The reprocessing unit 205 corrects the inclination as the first step of the reprocessing to reduce the inclination of the image distribution level even at a high temperature. As in low temperature, the process is performed to increase linearly.

In addition, since the image data transmitted from the infrared camera 100 is black and white data, when the image data is displayed on the monitor 210 as an image, it is difficult to check the image by visually determining whether the image is fired or not.

The reprocessing unit 205 performs a coloring process to appear on the monitor 210 by changing the color according to the temperature distribution as the second step of the reprocessing.

When the reprocessed image data is displayed on the monitor 210 in this manner, an image expressed in color (color) proportional to the temperature distribution is output to the monitor 210.

That is, by performing reprocessing for correcting and coloring the image data, it is possible to provide a screen that is easy to determine by eye.

In addition, the reprocessed image data is stored in the memory 204 and transmitted to the command vehicle monitor 300 or the operator mobile monitor 330 through the RF transmitter 206 to be expressed in color (color) proportional to the temperature distribution. The video is output.
