Target positioning method, device and system and computer readable storage medium

Abstract

The invention discloses a target positioning method, device and system and a computer readable storage medium, and relates to the technical field of computer vision, and the target positioning method comprises the steps: obtaining the height information and first angle information of an image collection device, wherein the height information is the distance between the image acquisition device and the ground, and the first angle information is the included angle between the image acquisition device and the ground; according to the height information and the first angle information, calculating the corresponding relation between the image position of the target in the image and the actual position of the target on the ground; acquiring image information through the image acquisition device, and acquiring image position information of the target according to the image information; and obtaining the actual position information of the target according to the image position information and the corresponding relation. According to the target positioning method, the position of the target can be automatically and accurately positioned.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a target positioning method, device, system and computer-readable storage medium. Background technique [0002] In recent years, with the rapid increase in the number of vehicles and the rapid expansion of urban areas, one-way roads tend to be very congested during morning and evening peaks on weekdays and holidays. In order to deal with the overwhelmed road traffic, the tidal channel can now change according to the indication of the lane, so as to change the correct driving direction of the road to maximize the use of road resources. At present, the existing tidal channels are based on the historical traffic flow data of the road to make a fixed switching plan. Generally, the tidal channel is opened or closed at a fixed time period, or the size of the two-way road traffic flow is manually observed on the spot, and it is changed by remote control or manually.

Problems solved by technology

At present, the existing tidal channels are based on the historical traffic flow data of the road to make a fixed switching plan. Generally, the tidal channel is opened or closed at a fixed time period, or the size of the two-way road traffic flow is manually observed on the spot, and it is changed by remote control or manually. Signs, signal lights and movable guardrails, etc., this method of manually identifying tidal channel control often makes lane switching often advance or lag behind, and lane switching cannot be performed at the best switching time of tidal channel, and for Traffic congestion caused by some emergencies cannot be responded quickly
