This invention discloses a sound field adjustment method and a computer-readable storage medium. The sound field adjustment method is applied to a multi-functional cockpit and includes: acquiring the user's position and spatial structure information of the sound field space; for any target speaker among the various speakers installed in the sound field space, calculating the sound field space parameters corresponding to the user's position based on the user's position and spatial structure information; determining the target processing parameters of the target speaker based on the sound field space parameters; processing the input audio signal of the target speaker according to the target processing parameters to obtain an output audio signal, and outputting the output audio signal using the target speaker. This invention improves the user experience in a multi-functional cockpit.

Embodiments of the present application provide an adversarial sample generation method and device and electronic equipment. The method comprises: obtaining a first stereoscopic object image of a sample object obtained by shooting the sample object when a target region of the sample object is provided with a calibration image, the calibration image comprising a plurality of calibration points; determining a coordinate conversion relationship between image coordinates of each calibration point in the first stereoscopic object image and image coordinates of each calibration point in the calibration image; generating an adversarial patch for a target object according to the coordinate conversion relationship; and obtaining a second stereoscopic object image of the sample object as an adversarial sample, the second stereoscopic object image having the adversarial patch provided on a target region of the sample object. The adversarial sample can be effectively generated for a recognition model suitable for recognition based on a three-dimensional image.
