Embodiment Construction

[0033] The emotion estimation device 10 according to the embodiment will be described with reference to the drawings.

[0034] Such as figure 1 As shown, the emotion estimation device 10 of the present embodiment includes an ECU (Electronic Control Unit) 12 which is a control unit mounted on a vehicle. That is, as an example, the emotion estimation device 10 of the present embodiment is mounted on a vehicle. Therefore, the user of the emotion estimation device 10 becomes an occupant of the vehicle.

[0035] The ECU 12 is configured to include a CPU (Central Processing Unit) 14 , a ROM (Read Only Memory) 16 , a RAM (Random Access Memory) 18 , a memory 20 , a communication interface 22 , and an input / output interface 24 . The respective structures are connected so as to be communicable with each other via the bus 26 .

[0036] CPU14 which is a processor is a central processing unit, and executes various programs and controls each part. That is, CPU14 reads a program from ROM...

Abstract

The invention relates to an emotion determination device, an emotion determination method and a program, which are used for determining emotion with high precision even if individual differences exist in expressions. The emotion determination device includes an image acquisition unit, an evaluation value setting unit, a correction value calculation unit, and an emotion determination unit. The image acquisition unit acquires a face image of a user. The evaluation value setting unit sets an evaluation value for each of the emotion classified into a plurality of moods including a calm state on the basis of the face image acquired by the image acquisition unit. The correction value calculation unit calculates a correction value using an evaluation value set on the basis of a calm face image acquired by the image acquisition unit at the timing of the calm state. The emotion determination unit determines the emotion of the user by reflecting the correction value calculated by the correction value calculation unit with respect to the evaluation value set by the evaluation value setting unit.

Description

technical field [0001] The present disclosure relates to an emotion inference device, an emotion inference method, and a non-transitory storage medium. Background technique [0002] For example, International Patent Application Publication No. 2019 / 193781 discloses an emotion inference device that infers a user's emotion. In the device disclosed in International Patent Application Publication No. 2019 / 193781, a set of evaluation values ​​for each emotional attribute, that is, a first evaluation value group is obtained, and the second evaluation value group obtained before the first evaluation value group is obtained. Correction processing is performed by evaluating the relationship of value groups. Specifically, when the difference between the evaluation values ​​in the first evaluation value group and the second evaluation value group does not exceed the reference value, the correction value for the emotion attribute with the highest evaluation value is reduced, and the co...
