Thermal image processing device, infrared imaging apparatus, thermal image processing method, and thermal image processing program

A thermal image processing method, comprising:

• outputting a trigger instructing that an infrared detector provided in a vehicle be calibrated;
• acquiring a thermal image detected by the infrared detector;
• detecting an object from the thermal image;
• calculating a possibility of collision between the object and the vehicle from a positional relationship between the detected object and the vehicle;
• and
• determining whether to calibrate the infrared detector on the basis of the possibility of the collision between the object and the vehicle,
• wherein, in the determining, it is determined not to calibrate if the possibility of the collision between the object and the vehicle is higher than a predetermined value regardless of an output of the trigger and determined that the calibration can be carried out if the possibility of the collision between the object and the vehicle is lower than the predetermined value.

A non-transitory computer readable medium storing a thermal image processing program that causes a computer to execute:

• a procedure of outputting a trigger instructing that an infrared detector provided in a vehicle be calibrated;
• a procedure of acquiring a thermal image detected by the infrared detector;
• a procedure of detecting an object from the thermal image;
• a procedure of calculating a possibility of collision between the object and the vehicle from a positional relationship between the detected object and the vehicle;
• and
• a procedure of determining whether to calibrate the infrared detector on the basis of the possibility of the collision between the object and the vehicle,
• wherein, in the procedure of determining, it is determined not to calibrate if the possibility of the collision between the object and the vehicle is higher than a predetermined value regardless of an output of the trigger and determined that the calibration can be carried out if the possibility of the collision between the object and the vehicle is lower than the predetermined value.
