Radio system based on RSSI ranging and machine vision algorithm

Abstract

The invention discloses a radio system based on RSS (received signal strength) distance measurement and a machine vision algorithm, which comprises an initialization module, a start detection module, a signal collection module, a conversion module, a position model, an algorithm module, a microphone module and an end detection module, the start detection module is connected with the end detection module and the signal collection module, the signal collection module is connected with the conversion module, the signal collection module and the conversion module convert collected signals into position models, the position models are transmitted to the algorithm module for connection, the algorithm module is connected with the microphone module, and the microphone module is connected with the end detection module. According to the radio system provided by the invention, a single microphone system is expanded into a tracking system and a microphone system, so that the microphone can track and radio by using an RSSI algorithm and a machine vision algorithm under the condition that a speaker moves, and the problem that the radio effect is not ideal under the condition of fixed radio is solved.

Description

technical field [0001] The invention relates to information and automatic control, in particular to a radio system based on RSSI ranging and machine vision algorithms. Background technique [0002] At present, offline teaching is still the mainstream teaching method in colleges and universities, and it is usually a mode in which multiple classes take classes together. In order to make the content of teachers' lectures clearly accepted by students, teachers are often equipped with microphones to make their lectures more effective. The installation method of the microphone is usually fixed, so that the sound collection area is relatively fixed, but the teacher may write on the blackboard or other moving positions during the lecture, resulting in the microphone's sound collection and amplification effect often cannot meet the teacher's needs. Therefore, how to It is very important for the development of teaching activities to effectively solve the problem of microphone pickup ...
