Abstract

The invention discloses a method for distance measurement between pulse array signals, comprising the following steps: S110, respectively converting an original pulse array signal and a reference pulse array signal from a pulse array signal domain to a pulse array characteristic domain to obtain an original pulse array characteristic and a reference pulse array characteristic; S110, respectively converting an original pulse array signal and a reference pulse array signal from a pulse array signal domain to obtain a reference pulse array characteristic; S110, respectively converting the original pulse array signal to a reference pulse array characteristic domain. S120, calculating a differential pulse array feature between the original pulse array feature and the reference pulse array feature in a pulse array feature domain; S130, calculating the energy of the differential pulse array feature, and transforming the energy into a distance metric between the original pulse array signal andthe reference pulse array signal. Thus, the distance measurement of the pulse array signal is extended from the pulse array signal domain to the pulse array characteristic domain, and the distance between the two pulse array signals can be conveniently and efficiently measured.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for measuring distance between pulse array signals. Background technique [0002] In recent years, the rapid development of big data, cloud computing, and artificial intelligence has driven a new round of industrial transformation and has had a profound impact on various fields of society. Generally speaking, by simulating the characteristics and abilities of the human brain, a computer perceives the environment, learns knowledge, and uses the knowledge to make the best decisions, eventually reaching artificial intelligence. Among them, in order to obtain the ability to perceive the external environment, and have hearing, vision, touch, etc. like humans, smart terminals usually deploy various sensors (such as visual sensors, lasers, radars, etc.). As the main carrier of information description and presentation, visual information plays an important role i...
