Embodiment Construction

[0029] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0031] As described in the background art, the application scenarios of the existing life detection equipment are limited, the detection cannot be completed well, and the detection effect is poor.

[0032] For example, the infrared detector detects the target based on ...

Abstract

The invention is suitable for the technical field of intelligent automobiles, and provides an in-vehicle life detection method and device, equipment and a storage medium. The method comprises the steps of: acquiring an xth radar frame signal collected by a preset millimeter wave radar in a vehicle; performing demodulation sampling and time-frequency conversion on the xth radar frame signal to obtain a first range dimension signal array; filtering the first range dimension signal array to obtain a second range dimension signal array; extracting the phase and confidence of a preset detection point in the second range dimension signal array; performing iterative filtering on the phase and confidence of the preset detection point of the xth radar frame signal according to the pre-extracted phase and confidence of the preset detection point of an (x-1)th radar frame signal to obtain a filtering result of the preset detection point of the xth radar frame signal; and when the filtering result is greater than a preset threshold, determining that there is a life at the preset detection point. The in-vehicle life detection method can be suitable for in-vehicle life detection in various scenes, and the detection effect is good.

Description

technical field [0001] The invention belongs to the technical field of smart cars, and in particular relates to a life detection method, device, equipment and storage medium in a car. Background technique [0002] With the popularization of vehicles, accidents in which children or pets are left in the vehicle to death are also gradually increasing. In the face of these painful lessons, it is urgent to configure life detection equipment. At present, life detection equipment mainly includes infrared detectors, ultrasonic radars and cameras. [0003] However, the existing life detection equipment has limited application scenarios, cannot complete the detection well, and the detection effect is poor. Therefore, there is an urgent need for an in-vehicle life detection method with better detection effect and a wide range of application scenarios. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a method, device, device, and s...
