[0021] The accompanying drawings are used to provide a further understanding of the present application and constitute a part of the specification. Together with the following specific embodiments, they are used to explain the present invention, but do not constitute a limitation to the present invention.

[0022] Figure 1 It is a schematic structural diagram of the vehicle image information acquisition device for toll auditing provided in Embodiment 1 of the present application. Specific Embodiments

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0024] Embodiment 1

[0025] Referring to Figure 1 , this embodiment provides a vehicle image information acquisition device for toll auditing, including:

[0026] A camera bracket 1 for installing a camera, with a connecting part 3 provided at the bottom. The connecting part 3 is a hollow prism; the prism can be a quadrangular prism or a pentagonal prism, etc.

[0027] A support rod 2 is in the shape of a prism. The connecting part 3 of the camera bracket 1 is sleeved on the top of the support rod 2, and the two are circumferentially positioned through the side surface of the prism. A bolt passes through the connecting part 3 of the camera bracket 1 and the support rod 2 and is fastened with a nut. The bottom of the support rod 2 is connected to the ground.

[0028] It can be understood that when the connecting part 3 of the camera bracket 1 is a hollow quadrangular prism, the support rod 2 is in the shape of a quadrangular prism; when the connecting part 3 of the camera bracket 1 is a hollow pentagonal prism, the support rod 2 is in the shape of a pentagonal prism, and so on. And when the inner diameter of the connecting part 3 of the camera bracket 1 is equal to the outer diameter of the support rod 2.

[0029] In this embodiment, the connection method between the camera bracket and the support rod can achieve quick disassembly and quick installation of the camera bracket. The image acquisition unit located on the camera bracket is the part that needs to be upgraded. Therefore, the device provided in this embodiment is convenient for subsequent expansion and upgrade.

[0030] And since only the camera bracket needs to be removed during the upgrade, without removing the support rod from the ground, it will not cause frequent damage to the ground. When the device needs to be upgraded, the maintenance cost is low.

[0031] In a preferred embodiment, a vehicle camera 4 facing the lane is installed on the first side elevation of the camera bracket 1, a front vehicle camera 5 facing the oncoming vehicle direction is installed on the second side elevation of the camera bracket 1, and a rear vehicle camera 6 facing the departing vehicle direction is installed on the third side elevation of the camera bracket 1. The included angle between the second side elevation and the first side elevation is greater than 90 degrees, and the included angle between the third side elevation and the first side elevation is greater than 90 degrees. Such a setting makes it easier to collect images of the front and rear of the vehicle.

[0032] Since there are many toll gates outdoors, problems such as unclear images caused by poor light will be faced. For this reason, this embodiment provides a supplementary lighting solution, specifically:

[0033] Continue to refer to Figure 1 , the vehicle image information acquisition device further includes:

[0034] A supplementary light 7 is provided on the support rod 2.

[0035] Preferably, one supplementary light 7 is provided at each of the upper and lower ends of the first side elevation of the support rod 2, and one is provided at the middle of the second side elevation and the third side elevation of the support rod 2 respectively.

[0036] In a preferred embodiment, the vehicle image information acquisition device further includes:

[0037] An oncoming vehicle signal receiver for receiving the signal of the approaching vehicle. A ranging radar can be selected to measure the distance between the vehicle and the vehicle image information acquisition device. When the vehicle approaches the vehicle image information acquisition device to a set distance, the ranging radar sends a signal to the oncoming vehicle signal receiver, which is used as the oncoming vehicle signal. The oncoming vehicle signal is used as a triggering factor for starting the supplementary light 7.

[0038] Furthermore, a light intensity sensor is provided inside the supplementary light 7, and the light intensity sensor outputs the light intensity value of the current environment;

[0039] When the light intensity value is lower than the set value, when the oncoming vehicle signal receiver receives the signal of the approaching vehicle, the supplementary light 7 is started.

[0040] Even further, the vehicle image information acquisition device further includes:

[0041] A timer is electrically connected to the power cord of the supplementary light. After the supplementary light 7 is started, timing begins;

[0042] When the timer counts the set time, the supplementary light 7 is turned off.

[0043] In summary, the image information collected by the vehicle image information acquisition device for toll audit provided in this embodiment includes vehicle license plates, vehicle types, number of axles, number of wheels, etc., which can provide rich and comprehensive materials for image recognition, facilitate improving the recognition accuracy of information such as vehicle license plates, vehicle types, number of axles, number of wheels, etc., and thus be more accurate when matching with the information in the database.
