Embodiment 1

[0058] see Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, a kind of wheel diameter testing device is provided, and this measuring device is suitable for measuring the wheel diameter of various vehicles 60, especially suitable for bicycles, electric vehicles, tricycles, motorcycles, scooters etc. The wheel diameter of the vehicle 60 is measured.

[0059] Specifically, the wheel diameter measuring device in this embodiment includes a main body 10, a sensing component 20, a distance measuring component 30, a photographing component 40, a correction plate 50 and a control host (not shown in the figure).

[0060] Wherein, the main body 10 includes a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are independent and spaced apart from each other, the gap between the first housing 11 and the second housing 12 Form the traffic identification area 13; the induction component 20 is arranged on the main body...

Embodiment 2

[0081] see Figure 13 As shown, according to another embodiment of the present invention, there is provided a wheel diameter measuring method implemented by the wheel diameter measuring device in the above embodiment, and the wheel diameter measuring method includes the following steps. :

[0082] Step S1: Use the correction plate 50 to correct the pixels corresponding to the unit length of the image captured by the photographing assembly 40 .

[0083] In this step, firstly, the control host computer is used to control the first distance-measuring element 31 and the second distance-measuring element 32, so that the first distance-measuring element 31 and the second distance-measuring element 32 work, and fine-tune the first housing 11 and the second For the housing 12, the deviation of the results measured by the first distance measuring element 31 and the second distance measuring element 32 is within 1 cm. At this time, the distance between the first housing 11 and the seco...

Abstract

The invention discloses a wheel diameter measuring device and a wheel diameter measuring method. The measuring device comprises a main body part, a sensing assembly, a distance measuring assembly, a photographing assembly, a correction plate and a control host. The main body part comprises a first shell and a second shell, and a clearance between the first shell and the second shell forms a passage identification area; the sensing assembly is arranged on the main body part and located at the entrance end of the passing recognition area; the distance measuring assembly comprises a first distance measuring element and a second distance measuring element; the photographing assembly is arranged on the main body part and located on the side, close to the passing recognition area, of the main body part. Scales are arranged on the correction plate; the control host is arranged on the main body part, and the sensing assembly, the distance measuring assembly and the photographing assembly are in communication connection with the control host. According to the wheel diameter measuring device, the wheel diameter can be rapidly measured, and when the wheel diameter measuring device and method are used in an intelligent bicycle identification gate system, vehicles on a bicycle lane can be rapidly and accurately identified.

Description

technical field [0001] The invention relates to the technical field of wheel diameter measurement, in particular to a wheel diameter measurement device and method. Background technique [0002] With the prevalence of shared bicycles, people's demand for safe and smooth dedicated bicycle lanes is increasing. Dedicated bicycle lanes can allow cyclists to ride more safely, reduce the risk of traffic accidents, and create a more friendly riding environment. In order to prevent bicycle lanes from being occupied by non-bicycles, some cities have chosen to install bicycle intelligent identification gate systems at the entrances and exits of bicycle lanes to ensure the right of way for bicycles. [0003] In order to identify bicycles, electric vehicles, motorcycles and other vehicles, it is necessary to collect multi-dimensional geometric quantity information of vehicles passing through the identification gate system, and the tire diameter is one of the typical distinguishing quanti...
