360-degree panorama based moving object detection method

Abstract

The invention provides a 360-degree panorama based moving object detection method. The method comprises the steps that the steps of performing vehicle periphery four-channel blind-area-free video image data acquisition; performing vehicle periphery four-channel video image processing and panoramic stitching so as to form a 360-degree panoramic top view; detecting a moving object at the periphery of a vehicle by adopting a global-local cascading space-time salience model according to the 360-degree panoramic top view; generating a boundary of the periphery of the vehicle according to dynamic data acquired in real time; and measuring the relative distance between the moving object and the boundary of the vehicle, and generating an alarm signal according to alarm rules. According to the invention, the driving state and speed of the vehicle are analyzed by adopting a machine vision technology, detection is performed on a moving object at the periphery of the vehicle according to a video sequence formed by the 360-degree top view, a timely and accurate alarm signal is provided by combining the driving state and the driving speed of the vehicle, a driver is reminded to adjust the driving state timely and drive carefully, and thus occurrence of traffic accidents is reduced or avoided.

Description

technical field [0001] The invention relates to the field of automotive electronic information technology processing, in particular to a moving object detection method based on a 360-degree panorama. Background technique [0002] As the potential of my country's automobile market continues to be released, the number of automobiles continues to grow rapidly, and a large number of traffic accidents follow. Due to factors such as lack of concentration, especially with the popularity of smart phones in recent years, some drivers answering calls and playing with mobile phones while driving at low speeds have also caused certain traffic accidents. In addition, the bloodshed caused by reversing has also attracted more and more attention. In the accidents caused by reversing, most of them are caused by the blind spots of vehicles. [0003] In order to effectively reduce or avoid traffic accidents caused by factors such as driver inattention or vehicle blind spots, major manufacturer...
