Embodiment 1

[0025] figure 1 It is a flow chart of a method for detecting a living body in a vehicle provided by an embodiment of the present invention. like figure 1 As shown, the method for detecting life in a vehicle specifically includes the following steps:

[0026] In step S101 , images in the vehicle are collected by an image acquisition device, and the collected images in the vehicle are detected based on the trained life detection model to determine whether there is a living body in the vehicle.

[0027] Specifically, a large number of living body images are collected through mobile terminals such as mobile phones and tablets or vehicle terminals such as driving recorders and in-vehicle cameras, and feature extraction or HOG is performed through SIFT (Scale-invariant feature transform, scale-invariant feature transform). (Histogram of Oriented Gradient, directional gradient histogram) feature extraction method to extract features of the collected life images, and train the extra...

Embodiment 2

[0057] The embodiment of the present invention also provides an in-vehicle life detection device, which is used to implement the in-vehicle life detection method provided in Embodiment 1 of the present invention. The following describes the in-vehicle life detection provided in the embodiment of the present invention The device is described in detail.

[0058] Figure 4 It is a structural diagram of an in-vehicle life detection device provided by an embodiment of the present invention, as shown in Figure 4 As shown, the living body detection device mainly includes: an image acquisition device 41, a judgment module 42, a confirmation module 43, and an alarm module 44, wherein:

[0059] The image acquisition device 41 is used to acquire images inside the vehicle.

[0060] The judging module 42 is configured to detect the collected in-vehicle images based on the trained life-body detection model, and judge whether there is a life-body in the car.

[0061] The confirmation mod...

Embodiment 3

[0077] Figure 5 It is a structural diagram of an in-vehicle life detection system provided by an embodiment of the present invention. like Figure 5 As shown, the in-vehicle life detection system includes a life detection device 51 that executes the in-vehicle life detection method described in the first embodiment. The in-vehicle life detection system also includes a data service device 52, a model Training device 53 and model service device 54 .

[0078] Specifically, the data service device 52, the model training device 53, the model service device 54 and the life detection device 51 are connected in sequence; the data service device 52 is used for the collection, preprocessing, storage and management of the model training data; the model training device 53 It is used to perform model training based on the model training data collected by the data service device 52 to obtain a life detection model, and to regularly update the life detection model based on the in-vehicle ...

Abstract

The invention discloses an in-vehicle life body detection method, device and system and a storage medium. The in-vehicle life body detection method comprises the steps: collecting an in-vehicle imagethrough image collection equipment, carrying out the detection of the collected in-vehicle image based on a trained life body detection model, and judging whether a life body exists in a vehicle or not; if the judgment result is yes, determining whether a life body exists in the vehicle or not again through an optical flow algorithm; and if the re-confirmation result is that the life body exists in the vehicle, giving an alarm to prompt. The in-vehicle life body detection method solves the technical problem that in the prior art, the accuracy of detecting the life body in the vehicle is low, accurately and efficiently detects the technical effects that whether the life body exists in the vehicle locked by the vehicle lock or not, gives out an alarm, and avoids misjudgment caused by image matting and mask attacks.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of detection, and in particular, to a method, device, system, and storage medium for detecting a living body in a vehicle. Background technique [0002] With the improvement of living standards, more and more families have purchased motor vehicles. While motor vehicles bring convenience to people's travel, they also bring new problems. The danger caused when pets are locked in the car alone. Studies have shown that when the outside temperature is about 35 degrees, the temperature in the closed car can rise to 65 degrees when the sun shines for 15 minutes. It will be fatal in the first half hour. Synthetic fibers such as instrument panels in the carriage contain benzene, which may cause leukemia in children, and may also lead to miscarriage and teratogenicity in pregnant women. The immune system has adverse effects; methanol is mainly from the fragrance in the car, and long-term inhala...
