Problems solved by technology

Therefore, not only the height of the target cannot be ignored, but also the two-dimensional plane target becomes a three-dimensional three-dimensional target, the traditional two-dimensional image stitching method is completely invalid, the target information is seriously lost, and reliable stitching cannot be achieved

Abstract

The invention discloses a vehicle positioning and tracking system and method based on three-dimensional visual stitching in a cabin. The system comprises a detection system, a transmission cable and a positioning system. The detection system is composed of a number of visual probes, a number of light sources and a switch. The video signals of all visual probes pass through the switch and are sent to the positioning system through a transmission cable. The positioning system is composed of a computer, a network card and a display. The detection system divides the whole cabin into a number of partitions of equal size. A visual probe is arranged at each corner of each partition. Each visual probe faces the cabin space of the partition at the same time. Each visual probe is slantly arranged. The measurement boundary point height of each visual probe is higher than the height of all vehicles in the cabin. The visual probes are prevented from detection blind spots and target missing. According to the invention, a computer vision technology and a partition method are used to realize accurate vehicle positioning and tracking in the cabin; the detection efficiency is improved; and the interference of manual factors is avoided to the maximum extent.

Description

technical field [0001] The present invention relates to a positioning and tracking system and method for vehicles in a cabin, in particular to a positioning and tracking system and method for vehicles in a cabin based on three-dimensional visual splicing technology. Background technique [0002] In the cabin of the cargo ship, various types of vehicles (such as transport vehicles, rescue vehicles, various armored vehicles, etc.) will be transported. In order to ensure that all vehicles entering the cabin can safely and quickly reach their designated positions, and leave the cabin efficiently, safely and reliably, it is necessary to monitor the vehicles entering the cabin to determine the position and attitude of each vehicle, and The track of the vehicle in motion is tracked to improve the digitalization level of the ship. [0003] Among various moving target positioning and tracking detection technologies, the positioning and tracking technology based on computer vision ha...
