Example Embodiment

[0027] Example 1

[0028] The industrial camera is installed on the top of the traffic sand table model, and the industrial camera is used to collect video images of the traffic sand table model, and flexibly adjust the number and height of the traffic sand table model according to the size of the traffic sand table model, so that the traffic sand table model Each scene of the traffic sand table model can be completely collected, and the industrial camera is connected to the video positioning server through a data line.

[0029] The industrial camera adopts a black and white camera lens, and an infrared filter is set outside the black and white camera lens. Due to the effect of the filter, in the image formed by the black and white camera, except for the light emitted by the infrared LED lamp bead, can pass through the filter , Other light will not pass, the background environment will appear black, and the image formed by the infrared lamp will be a white spot, which will be captu...

Example Embodiment

[0031] Example 2

[0032] The smart car simulates the driving process of a city vehicle, the surface of the flat road module is provided with a magnetic track line, and the smart car drives on a predetermined route in a track-seeking manner.

Example Embodiment

[0033] Example 3

[0034] The traffic sand table model includes the basic modules of the urban road traffic system, and is expandable. The traffic sand table model is equipped with traffic sensors and corresponding actuators, the actuators include signal light groups, traffic signs, street lights, lawns, etc.; the urban landscape module includes buildings, parking lots, urban greening, etc., to simulate urban landscapes; The equipment module is equipped with a card reader, a power supply, a transmission module and other equipment, the traffic sand table model is made of a combination of environmentally friendly materials and aluminum alloys, and a universal wheel is installed at the bottom of the traffic sand table model.

Abstract

The invention discloses an intelligent trolley positioning system and method based on radio frequency identification and image identification, relates to the technical field of intelligent urban traffic simulation. The system comprises a traffic sand table model, an industrial camera, an intelligent trolley, an IC card reader, a wireless data receiving terminal and a video positioning server. An IC card reader on the traffic sand table model reads IC card information of the intelligent trolley and sends data to a wireless data receiving terminal, and the wireless data receiving terminal sendsthe data to a video positioning server through a serial port, analyzes the data and determines the ID and basic position information of the trolley. The industrial camera captures position coordinatesof the trolley by using an optical filter, information obtained by IC card reader is matched with ID and accurate position of the trolley. The industrial camera and the card reader are utilized to connect the video positioning system and the IC system, the position of the intelligent trolley on the traffic sand table model is accurately positioned, real-time driving track tracking is carried out,and the requirements of a modern simulation laboratory are met.

Description

technical field [0001] The invention relates to the technical field of smart city traffic simulation, in particular to a smart car positioning system and method based on radio frequency identification and image recognition. Background technique [0002] At present, the traditional sand table is mainly based on real scene display, especially the smart sand table used in transportation, which can not only fully display the scene, but also realize the interconnection with smart devices, so as to achieve the simulation based on the small scene of the sand table. Various traffic events in the environment. [0003] However, there is still a lack of a system for accurate calculation and measurement of moving objects in the existing sand table, such as the movement of the car model. A modern simulation laboratory not only needs a real-scene sand table, but more importantly, generates data through the sand table scene and the simulated vehicle in the scene, so as to effectively supp...
