Embodiment 1

[0027] An embodiment of the present invention provides a driving camera system, such as figure 1 As shown, including: camera 1, humidity sensor 2, vehicle display 3, controller 4, controller 4 is connected with camera 1, humidity sensor 2, vehicle display 3,

[0028] Wherein the camera 1 converts the optical image signal into an electrical signal for storage or transmission. When we shoot an object, the light reflected on the object is collected by the lens of camera 1, making it focus on the light-receiving surface of the imaging device (such as the target surface of the imaging tube), and then the light is converted into electrical energy by the imaging device, that is, "Video signal".

[0029] The camera 1 in this embodiment is used to capture images in vehicles to form a driving camera system to help drivers view image information around the vehicle, which is conducive to safe driving. This camera 1 is arranged on the license plate side of the vehicle rear, and towards t...

Embodiment 2

[0040] An embodiment of the present invention provides a driving camera method, which is used in the driving camera system in Embodiment 1, such as image 3 shown, including the following steps:

[0041] S31. Obtain the humidity value of the lens and the rear image of the vehicle. For example: the humidity sensor detects that the humidity value on the lens on the camera is 10%, and the rear image of the vehicle includes the license plate number of the vehicle behind, the color of the vehicle behind, and trees or buildings around the rear, etc.

[0042] S32. Determine whether the humidity value is not less than a preset humidity threshold. The preset humidity threshold here is a preset humidity reference threshold based on application scenarios and different seasons, so as to facilitate judging whether the humidity on the lens reaches the reference value. For example: the preset humidity threshold is 5%. However, the humidity value on the lens detected in step S21 is 10%, sin...

Embodiment 3

[0047] This embodiment provides a driving camera device, such as Figure 4 Shown, be used in the driving camera system in embodiment 1, comprise:

[0048] Obtaining module 41, for obtaining the humidity value of camera lens and vehicle rear image;

[0049] Judging module 42, used to judge whether the humidity value is not less than the preset humidity threshold;

[0050] The control module 43 is used to control the conductive sheet of the camera to heat the transparent resistance wire until the resolution of the image behind the vehicle reaches the preset resolution when the humidity value is not less than the preset humidity threshold.

[0051] as an optional implementation. In the driving camera device in this embodiment, the preset resolution is set according to the image that can be recognized by the driver's normal eyesight according to different light intensities.

[0052] In the driving camera method in this embodiment, when the driver is driving in rainy or foggy da...

Abstract

The invention discloses a driving photographing system and a method and device thereof. The system comprises a camera, wherein an eyeglass is arranged in a lens of the camera, a transparent resistance wire is laid in the eyeglass, and a conductive sheet which is electrically connected with the transparent resistance wire is arranged on the edge of the eyeglass; a humidity sensor which is used for detecting the humidity of the eyeglass; a vehicular display which is used for displaying an image photographing result of the camera; and a controller which is connected with the camera, the humidity sensor and the vehicular display and is used for controlling the conductive sheet of the camera to heat the transparent resistance wire when the humidity detected by the humidity sensor is greater than a preset humidity threshold. According to the system, the method and the device, the transparent resistance wire is heated through utilization of the conductive sheet, so the eyeglass of the camera wetted by water drops can be rapidly heated to dry; the image photographing effect of the camera is improved; the image with relatively good image quality is transmitted to the vehicular display; a driver can watch an image at the rear side of a vehicle clearly; and the driver can drive safely.

Description

technical field [0001] The invention relates to the technical field of photographing, in particular to a driving camera system and its method and device. Background technique [0002] Usually, the driver can only see the image in front of the vehicle while driving, but cannot see the image behind the vehicle. The camera converts the optical signal into an electrical signal to obtain a video signal. If it can be combined with the working principle of the camera to collect The rear image is transmitted to the on-board monitor, which can help the driver to obtain the rear information of the vehicle, which is beneficial for the driver to reverse the vehicle into the garage or check the situation behind the vehicle to facilitate safe driving. [0003] At present, when the camera on the vehicle is shooting in rainy days, there are raindrops on the lens, resulting in unclear shooting results, so the driver cannot clearly obtain the image information of the camera while driving. At...
