Embodiment approach 1

[0022] Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings. The thermal image processing device 100 according to the embodiment is mounted on an automobile. The thermal image processing device 100 detects an object by processing a signal of a thermal image acquired from the infrared camera 200, and based on a positional relationship between the own vehicle and the detected object and a change in the positional relationship, an object is detected between the own vehicle and the detected object. The driver is notified in the event of a possible collision with an object.

[0023] figure 1 It is a functional block diagram of the thermal image processing device 100 according to the embodiment. The thermal image processing device 100 is connected with an infrared camera 200 , a display device 201 , and a sound output device 202 . In addition, the thermal image processing device 100 is connected to the in-vehicle communication bus, a...

Embodiment approach 2

[0054] Next, Embodiment 2 will be described. The functional blocks of the second embodiment are the same as those of the first embodiment. Therefore, descriptions of common functions or processes are appropriately omitted here. Embodiment 2 is different in processing that the driver is warned when the possibility of collision with an object is higher than a predetermined value.

[0055] refer to image 3 A specific example will be described. exist image 3 In the thermal image 400 of , an object 402 passes in front of the ego vehicle. In the case where the TTC of the object 402 is not greater than the predetermined value T1, and in the case where the TTC is smaller than the predetermined value T2, there is a risk of the own vehicle colliding with the object 402. Therefore, the thermal image processing device 100 warns the driver. And, this warning is continued for a predetermined period. And, during the warning to the driver, it can replace image 3 The displayed image...

Embodiment approach 3

[0061] Next, Embodiment 3 will be described. The functional blocks of the third embodiment are the same as those of the first and second embodiments. Therefore, descriptions of common functions or processes are appropriately omitted here. In addition, Embodiment 3 differs from Embodiment 2 in that a process of forcibly performing correction is added.

[0062] refer to Figure 5 , and the processing according to Embodiment 3 will be described. Figure 5 It is a flowchart of the thermal image processing method concerning Embodiment 3. Figure 5 flow chart with Figure 4 The difference of the flow chart is that step S17 is added. Step S17 will be described below.

[0063] When it is determined in step S10 that the correction process is to be performed (step S10: YES), the determination unit 106 then determines whether or not it is necessary to forcibly perform the correction process (step S17).

[0064] Specifically, the determination unit 106 determines, for example, whet...

Abstract

A thermal image processing device (100) is provided with a thermal image acquisition unit (101) for acquiring a thermal image detected by an infrared detector installed in a vehicle, an object detection unit (102) for detecting an object from the thermal image, a positional relationship computation unit (103) for computing a positional relationship between the detected object and the vehicle and also computing a change of the positional relationship, and a determination unit (106) for determining whether to calibrate the infrared detector on the basis of the computed change of the positional relationship.

Description

technical field [0001] The invention relates to a thermal image processing device, an infrared photographing device, a thermal image processing method and a thermal image processing program. Background technique [0002] In recent years, many products using infrared cameras equipped with infrared detectors have been developed as products for security or for moving objects. Infrared cameras can detect people or objects in environments where visible light does not exist, such as at night, because they detect heat in captured images. Therefore, by using such a sensor in, for example, an automobile or the like, it is possible to detect a person or an object in a range that headlights cannot reach at night. Furthermore, by warning the driver or the like of a person or object that may collide with the car or the like, it contributes to the improvement of the safety of the car or the like. [0003] Such an infrared camera is affected by changes in ambient temperature, etc., and i...
