The invention discloses a distance measuring method, a terminal and a computer-readable storage medium. The method includes: acquiring a feature value of audio data from an ultrasonic sensor, and generating a first feature vector; The vector encoding process is a second feature vector, the dimension of the second feature vector is smaller than the dimension of the first feature vector, and the third feature vector obtained after decoding the second feature vector is the same as the first feature vector The dimensions are the same, and the data difference between the third eigenvector and the first eigenvector meets a preset condition; according to the second eigenvector, the distance between the ultrasonic sensor and the user is analyzed. After extracting the eigenvector of the original data and compressing it through encoding processing, the difference between the eigenvector data and the original data is controlled to be small. Based on the essence data, the ranging analysis can accurately analyze the distance between the mobile phone where the ultrasonic sensor is located and the user. distance.
Description
technical field [0001] The present invention relates to the field of mobile terminals, and in particular, to a ranging method, a terminal and a computer-readable storage medium. Background technique [0002] In the field of mobile phones, it is a basic function for the mobile phone to automatically turn on and off the screen when the user makes a call. At present, the usual practice is to set an infrared sensor on the front of the mobile phone, and use the infrared sensor to detect the distance between the user and the mobile phone. The distance determines whether the user is on a phone call, so as to control the mobile phone to automatically turn on and off the screen. [0003] The full-screen design requires as few openings as possible on the front of the mobile phone, and the use of infrared distance sensors inevitably requires openings on the front of the mobile phone. Therefore, there is a need for a mobile phone that can automatically turn on and off the screen when ma...
