Problems solved by technology

[0004] However, the calibration work at the time of shipment from the factory is the calibration work under ideal conditions regardless of the environmental conditions
Therefore, in the environment where the infrared detection device is actually used, there is a problem that if the influence of the ambient temperature, the attenuation of infrared radiation energy corresponding to the distance between the infrared detection device and the object to be measured, and the measurement location If the conversion table takes into account the influence of the reflection of infrared radiation energy generated by the layout of the room, it will not be possible to obtain accurate temperature values.

Embodiment approach 1

[0123] figure 1 It is a figure for demonstrating the temperature correction process in the infrared detection system of this Embodiment 1. In the temperature correction process according to the first embodiment, the user holds the mobile terminal 100 , and the infrared detection device 110 detects infrared rays radiated from the mobile terminal 100 . In addition, the infrared detection system is used, for example, in the care or monitoring of a specific person such as the elderly.

[0124] The portable terminal 100 is, for example, a smartphone, a mobile phone, a tablet computer, or a notebook computer. The infrared detection device 110 measures the infrared radiant energy of the object to be measured, and converts the measured infrared radiant energy into a temperature value. The infrared detection device 110 stores a conversion table associating infrared radiation energy with a temperature value, and converts the measured infrared radiation energy into a temperature value ...

Embodiment approach 2

[0220] Next, an infrared detection system according to Embodiment 2 will be described. In the first embodiment described above, the infrared detection device 110 determines the position of the portable terminal 100 as a heat source by detecting a periodic change in the temperature of the portable terminal 100 as a reference heat source, while in the second embodiment, the infrared detection device 110 recognizes the movement pattern of the portable terminal 100 as a reference heat source, detects the pattern, and specifies the position of the portable terminal 100 as the heat source.

[0221] Figure 14 It is a figure which shows the structure of the infrared detection system of this Embodiment 2. Figure 14 The illustrated infrared detection system includes a portable terminal 400 and an infrared detection device 410 . In addition, in Embodiment 2, the same components as those in Embodiment 1 are given the same reference numerals, and description thereof will be omitted.

Abstract

The present disclosure provides an information processing method and system, a portable terminal, an infrared detection device, and a program capable of performing temperature correction of an infrared detection device in an actual use environment easily and at low cost. The infrared detection device obtains measurement information obtained by measuring infrared radiant energy in a measurement range including the portable terminal, obtains information indicating a reference temperature, and detects a measured object corresponding to the portable terminal from the measurement range based on the measurement information. In the infrared radiant energy distribution area of ​​the infrared radiant energy area, a conversion table for converting infrared radiant energy into a temperature value is corrected based on the reference temperature and the detected infrared radiant energy in the infrared radiant energy distribution area.

Description

technical field [0001] The present disclosure relates to an information processing method, an information processing system, a portable terminal, an infrared detection device, and a program for an infrared detection device that measures infrared radiation energy of a measurement object and converts the measured infrared radiation energy into a temperature value. Background technique [0002] Conventionally, an infrared detection device that detects the temperature of a measurement object such as a person in a non-contact manner has been used. The infrared detection device detects infrared radiant energy emitted from an object, converts the detected infrared radiant energy into an apparent temperature, and displays an image showing a temperature distribution. For example, an abnormality in a person's body temperature can be detected based on temperature distribution information. [0003] In the infrared detection device, in order to convert the infrared radiant energy into a...
