Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0034] The scheme of the present invention is specifically as follows:

[0035] First, the positioning of the camera scene

[0036] The test site for venue road driving is composed of several test subjects, which are organized together according to a certain route. Two different subjects are connected by roads in the test room to form a loop. That is to say, candidates start the test from the starting point and the vehicle returns to the starting point after passing all subjects. When the vehicle enters each test subject, it will trigger the start signal of the subject. The starting signal of the present invention is a satellite positioning signal, including GPS, Beidou, Glonass, etc., and this type of differential GPS signal installed on the test vehicle travels to the pre-set test subject range to indicate that the test subject begins. . A start signal is calibr...

Abstract

The invention provides a camera tracking system and method based on a satellite positioning signal, and belongs to the field of traffic management. The camera tracking system based on the satellite positioning signal comprises a positioning satellite, a fixed satellite signal receiving base station arranged in a test site, a vehicular evaluation system arranged on a test vehicle, a database server, an application program server and a video monitoring server, which are arranged in a control center, and a camera tripod head arranged in the test site; the fixed satellite signal receiving base station can carry out reference satellite positioning and data transmission; a differential GPS satellite receiving point is arranged on the vehicular evaluation system; the positioning satellite sends a satellite positioning signal to the fixed satellite signal receiving base station, the signal keeps a constant value, namely a reference value after being calibrated, and when the satellite positioning signal generates positioning drift according to the satellite data receiving condition, an offset is generated.

Description

technical field [0001] The invention belongs to the field of traffic management, and in particular relates to a camera tracking system and method based on satellite positioning signals. Background technique [0002] The second test for motor vehicle drivers is commonly known as field road driving. Drivers must complete a number of subjects required by the Ministry of Public Security's "123" order in the test site to pass the test. Depending on the motor vehicle driver's permission level applied for by the driver, the completed subjects are also different. For example, if the driving permission level is C1, you need to complete "reversing into the garage", "positioning parking and starting on a slope", "Side parking", "right-angle turn" four subjects. With the continuous improvement of people's living standards, the number of students taking the motor vehicle driver's test is also increasing year by year, and the difficulty of test supervision is also increasing. In the exa...
