Embodiment Construction
[0025] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.
[0026] The following describes the intelligent roadside unit and its information processing method according to the embodiments of the present application with reference to the accompanying drawings.
[0027] In the related art, since the sensitivity of each camera is fixed, for some specific scenes, the problem of inaccurate recognition of the intelligent roadside unit may occur. For example, for some scenes without street lights, the light intensity of the road during the day and night is relatively different, and the ligh...

The invention provides an intelligent roadside unit and an information processing method thereof. The intelligent roadside unit comprises a light sensor which is used for generating current light intensity information, a highlight camera which is used for acquiring a highlight image, a dark light camera which is used for acquiring a dark light image, a controller which starts the highlight camerafor shooting when the current light intensity is greater than a first light intensity threshold value, starts the dark light camera for shooting when the current light intensity is smaller than a second light intensity threshold value and extracts the vehicle information according to the highlight image or the dark light image, wherein the second light intensity threshold value is smaller than thefirst light intensity threshold value. The light sensor is arranged to detect the light intensity of the shooting area, the cameras with different sensitivities are started according to the change ofthe light intensity so as to acquire the highlight image or the dark light image, and the vehicle information is extracted according to the highlight image or the dark light image, so that the recognition accuracy can be improved for a scene with large light intensity change.
Description
technical field [0001] The present application relates to the field of traffic technology, in particular to an intelligent roadside unit and an information processing method for the intelligent roadside unit. Background technique [0002] Intelligent roadside unit is an important support for automatic driving. With the improvement of intelligent demand for intelligent roadside units, the requirements for the perception ability of intelligent roadside units are getting higher and higher. It is necessary to add various sensor detectors on top of intelligent roadside units to improve the active perception of intelligent roadside units ability. [0003] However, since the sensitivity of each camera is fixed, for some specific scenes, there will be a problem of inaccurate recognition. Contents of the invention [0004] The present application proposes an intelligent roadside unit and an information processing method of the intelligent roadside unit, which are used to solve th...
