Embodiment Construction

[0046] Below in conjunction with the accompanying drawings and specific embodiments, the present invention will be described in detail.

[0047] Due to the use of GPS or RFID, it is necessary to install a position consisting of a GPS module and an RFID module in the forklift.

[0048] UWB positioning technology belongs to a kind of wireless positioning. Popular wireless positioning technologies include GPS positioning, Beidou positioning,

[0049] Wireless positioning technology refers to a measurement method and a calculation method used to determine the location of a mobile user, that is, a positioning algorithm.

[0055] S1: each camera in the warehouse collects video stream data in the warehouse target area.

[0056] The camera includes a camera terminal array, a data receiving module and a processing server. The camera ends

[0063] Due to the previous step, the error between the real image and the real timestamp cannot be eliminated. Simultaneously in multiple video stream...

Abstract

The invention discloses a positioning method and a positioning system for synchronizing UWB and UTC time stamps. Based on UTC time correction, the MFCC algorithm is used to synchronize multiple video streams to obtain a unified UTC time of frame data, which is combined with UWB position information to obtain The transformation matrix between the position of the target object in the image and the actual physical position of the target object. Based on this technology, it can be used for intelligent monitoring applications such as forklift running track, busy line status, motion analysis, and operating efficiency. A series of important indicators can be obtained, which will help managers conduct unified management and scheduling, and effectively improve The use efficiency of forklifts and the work efficiency of workers reduce the occurrence of idle work and sabotage, so that the overall economic output of warehousing can be improved.

Description

Positioning method and positioning system for joint UWB and UTC timestamp synchronization technical field The present invention relates to warehousing intelligence management field, relate in particular to a kind of positioning method of joint UWB and UTC time stamp synchronization. law and positioning system. Background technique At present, the warehouse storage intelligent management technology is constantly improving, and the forklift management strategy is paid more and more attention. The real-time location information and running track of the vehicle are more and more important for the overall grasp of warehouse managers. by targeting warehousing The statistics of forklifts in the area allow decision-makers to grasp the number and operation of forklifts in each area in time, which is convenient for forklifts. The scheduling of trucks greatly improves the efficiency of forklifts. [0003] The method for monitoring the running track of the forklift on the marke...
