Novel multiple spectra acoustic camera and identification method

Abstract

The invention relates to a novel multiple spectra acoustic camera and an identification method. The novel multiple spectra acoustic camera is used for ultrasonically imaging and identifying human body or object under a complex environment so as to identify the human body and object information. The novel multiple spectra acoustic camera comprises a hardware component and an image processing component; the hardware component comprises a fixing plate and an ultrasonic generator array and a receiver array which are arranged on the fixing plate; the ultrasonic generator array and the receiver array are simultaneously connected with a collecting processing circuit; the image processing component comprises an emitting / collecting processing module and an imaging and identifying processing module. The invention has the following advantages: 1) the novel multiple spectra acoustic camera can be used for detecting under a bad optical environment, such as night, has wider practicability and can work under a complex working condition; 2) the state information of human body and object can be acquired in real time through imaging and identification according to the invention and the worker can conveniently observe and treat; 3) due to the special nature that the ultrasonic wave is different from the optics, a human body image formed by an ultrasonic camera contains no excessive privacy information and has higher confidentiality.

Description

Technical field [0001] The invention discloses a new type of multi-spectrum acoustic camera, in particular a new type of multi-spectrum acoustic camera and a recognition method, which can be used for ultrasonic imaging and recognition of human bodies or objects in a complex environment to recognize the information of other people's bodies and objects. Background technique [0002] Real-time imaging and recognition technology is now widely used in all aspects of production and life. Its function is to obtain some relevant attributes and information after recognizing objects or human bodies and provide them to subsequent processing systems for processing. In daily applications, real-time imaging and recognition systems mostly use optical systems. For example, in the home, real-time imaging and recognition systems can perform pattern recognition on households at home and monitor the living conditions of the elderly and children. For example, the elderly and children are dangerous wh...

AI Technical Summary

Problems solved by technology

For example, the elderly and children are at a certain risk when they fall. If they are not detected and dealt with in time, they may have certain risks and cause irreparable consequences.

The traditional method can add a camera to identify it optically, but the optical camera is difficult to monitor at night or in low-light conditions indoors

Moreover, personal activity information has a certain degree of privacy. The optical camera will clearly distinguish the behavior of the human body during the recording process, which may easily cause infringement and leakage of personal privacy.
