determining a child retention state in the vehicle based on the first comparison result, the second comparison result, and the third comparison result.
5. The in-vehicle child monitoring method according to claim 4,
the step of comparing the two adjacent temperature image information to obtain a first comparison result comprises the following steps:
comparing the latest two adjacent temperature image information to obtain a first contact ratio of the two temperature image information, and determining a first change rate based on the first contact ratio;
the step of comparing the two adjacent ultrasound image information and obtaining a second comparison result comprises:
comparing the latest two adjacent ultrasound image information, acquiring a second coincidence degree of the two ultrasound image information, and determining a second change rate based on the second coincidence degree;
the step of comparing the two adjacent sound vibration information and obtaining a third comparison result comprises the following steps:
and comparing the latest two adjacent pieces of sound vibration information, acquiring a third coincidence degree of the two pieces of sound vibration information, and determining a third change rate based on the third coincidence degree.
6. The in-vehicle child monitoring method according to claim 5, wherein the step of determining the child staying state in the vehicle based on the first comparison result, the second comparison result and the third comparison result comprises:
determining that a child is stranded within the vehicle if any of the first, second, and third rates of change is greater than a first threshold;
determining that no child is stranded within the vehicle if the first rate of change, the second rate of change, and the third rate of change are all less than the first threshold.
7. The in-vehicle child monitoring method according to claim 5, wherein the step of determining the child staying state in the vehicle based on the first comparison result, the second comparison result and the third comparison result comprises:
reacquiring two other rates of change if only one of the first rate of change, the second rate of change, and the third rate of change is greater than a second threshold;
determining that a child is detained within the vehicle if at least one of the two newly acquired rates of change is greater than a second threshold;
determining that no child is stranded in the vehicle if both of the newly acquired rates of change are less than the second threshold;
determining that a child is stranded within the vehicle if at least two of the first rate of change, the second rate of change, and the third rate of change are greater than a second threshold.
8. The in-vehicle child monitoring method according to any one of claims 4 to 7, further comprising:
generating alarm information when the child retention state is that the child is retained;
and when the vehicle is powered off, the vehicle speed is zero and the vehicle door is closed, generating the in-vehicle child monitoring instruction.
9. A computer-readable storage medium, characterized in that,
the computer-readable storage medium stores a computer program implementing the in-vehicle child monitoring method according to any one of claims 4 to 8.
