Abstract

The invention is applicable to the technical field of measurement, and provides an acoustic detection device, system and method, computer equipment and a storage medium. The acoustic detection devicecomprises a sound source, and an acoustic field detector arranged in front of the output end of the sound source; the acoustic field detector comprises at least one multi-directional acoustic field detection component, each multi-directional acoustic field detection component comprises multiple laser detection devices; the multiple laser detection devices are arranged in a preset manner, so that detection light beams corresponding to the multiple laser detection devices can be interweaved to form a two-dimensional meshy cross section on a detection plane in front of the output end of the soundsource, and the laser detection devices are arranged in such the arrangement manner to detect the acoustic field on the two-dimensional meshy cross section. According to the device, system and methodprovided by the invention, the acoustic field to be detected can be continuously sampled, via simultaneous measurement in multiple directions, the continuous and multi-dimensional measured data can be provided for a subsequent process for computing the shape of a detection target, and thus the finally measured shape of the detection target has the relatively high resolution.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to an acoustic detection device, system, method, computer equipment and storage medium. Background technique [0002] Acoustic detection has a wide range of applications in underwater target detection, seabed topographic measurement, medical ultrasonic imaging, industrial non-destructive testing and other fields. [0003] According to the different principles, the current acoustic detection can basically be divided into two categories: one is based on the information of the sound wave receiving end, and uses the receiving end data as the scattering point to perform backpropagation calculation on the sound wave to solve the distribution of the sound wave scattering point, that is, to obtain the target The other is to imitate the method of laser radar ranging scanning imaging, scan and measure the target, and stitch the ranging results together to form the target point...
