Abstract

The invention discloses a moving target tracking method based on a cascade detector. The moving target tracking method comprises the following steps of (1) initializing a related filtering tracker; (2) initializing a cascade detector; (3) enabling the correlation filtering tracker to obtain a first region of interest; (4) detecting a cascade classifier target; (5) synthesizing the first region ofinterest and the detection region; (6) updating the tracking model and the cascade detector, wherein the first region of interest is obtained through the correlation filtering tracker, the cascade detector comprises a variance classifier, a multi-channel random fern classifier and a related consistent classifier, the detection area is acquired through the three classifiers, the first region of interest and the detection area are subjected to weighted correction to acquire the second region of interest, so that the oscillation of a tracking result can be effectively prevented. Meanwhile, the accuracy of the first region of interest acquired by the tracking model can be ensured by adopting the cascade detector.

Description

technical field [0001] The invention belongs to the technical field of target tracking, and more particularly relates to a moving target tracking method based on cascaded detectors. Background technique [0002] With the development of science and technology, the requirements of people's life, study and work on smart devices are also increasing. In the field of video surveillance, in the past, only static records could be made, and then used to monitor a certain area or record what happened in a certain area within a certain period of time, but the current social environment requires monitoring equipment to be more intelligent, capable of realizing remote Observing video images from a distance and from multiple directions requires image equipment that can track and automatically analyze and process them in real time. For example, automatic tracking of interested targets, detection of various targets, real-time tracking, positioning alarms, etc. These technical requirements ...
