The following description relates to a vehicle image security system, and more particularly to a vehicle image security system using a combined camera module and distributed computing.

【0002】

The vehicle image security system is an electronic system often used in today's vehicles. By assembling a camera around the body to capture images around the body, it reduces the visual dead angle of driving and enhances driving safety. Most of the traditional vehicle imaging systems use a central computing mechanism, which includes multiple car cameras and a central computing system. All car cameras output the captured images to the central computing system, and all image detection processes are performed by the central computing system. For example, obstacle detection or road offset detection.

[0003]

The advantage of this mechanism is that the camera only needs to have a simple structure and circuit, and it is easy to meet the requirements of the car camera for small size and heat and vibration resistance. In addition, the functions of the vehicle imaging system can be modified or added by simply updating the program of the central computing system. However, the disadvantage of this mechanism is that the central computing system must bear all the calculations, so it is necessary to configure high-order processing modules and more memory. Once the hardware of the original central computing system cannot be loaded with new functions, the owner can only use the expensive operation to update the central computing system in order to use the new functions.

[0022]

Please refer to FIG. 1, which is a block diagram of a first embodiment of a vehicle image security system according to the present invention. In the figure, the vehicle image security system is applied to a mobile vehicle 7 having a display screen 60 and a horn 61. The vehicle image security system includes a photographing module 10, a left photographing unit 211, a right photographing unit 212, a front side photographing unit 213, and a central control module 32. The photographing module 10 is disposed on the rear side of the mobile vehicle 7, and includes a rear side photographing unit 214, a first image processing unit 51, and a control unit 31. The image capturing unit may be a visible light vehicle camera or an infrared vehicle camera, and the output image signal may be analog signal (NTSC/PAL) or digital signal (LVDS, Ethernet).

[0023]

The rear side photographing unit 214 can capture the external rear side image 224 of the action vehicle 7, and the first image processing unit 51 performs an image detecting process on the rear side image 224, for example, an obstacle detecting process 41, if the image is from the rear side. When an obstacle object is detected in 224, a warning signal 510 is generated. Alternatively, the first image processing unit 51 may perform a view conversion process 46 on the back side image 224 to generate a view angle converted image 225, such as a bird's eye view processing. Alternatively, the first image processing unit 51 may perform display range processing on the rear side image 224, generate a new image from the rear side image 224, or the view angle conversion process 46 and the display range process simultaneously. Alternatively, the first image processing unit 51 may superimpose the warning signal 510 on the back side image 224 or the view angle converted image 225 in an image presentation manner to generate the superimposed image 226.

[0024]

It should be noted that, in the first embodiment, the obstacle detection processing 41 is taken as an example, but the limitation is not limited thereto. The image detection processing executable by the first image processing unit 51 may further include a road offset. Detection processing, a moving object detection processing, a left and right blind area detection processing, a front collision detection processing, or a rear side detection processing.

[0025]

The control unit 31 can receive the control signal 310 through a communication interface, and selectively output the back side image 224, the view angle converted image 225, the superimposed image 226, or/and the warning signal 510 according to the control signal 310. The left side photographing unit 211, the right side photographing unit 212, and the front side photographing unit 213 respectively capture the left side image 221, the right side image 222, and the front side image 223 outside the action carrier 7, and transmit the same to the central control module 32. The central control module 32 is electrically connected to the camera module 10, and outputs a control signal 310 to the control unit 31 through the communication interface to selectively receive the rear side image 224, the view angle converted image 225, the superimposed image 226, or/and the alert. Signal 510.

[0026]

The central control module 32 can produce different display screens as needed. For example, the central control module 32 may perform perspective conversion on the rear image 224, the left image 221, the right image 222, and the front image 223, respectively, and combine the converted image to generate a bird's-eye image 320, as shown in FIG. It is shown in part (A) and output to the display screen 60 for driver's reference to improve driving safety.

[0027]

Alternatively, the central control module 32 can also be combined with the bird's-eye image 320 and the warning signal 510 and output to the display screen 60. For example, as shown in part (B) of FIG. 2, the first image processing unit 51 performs the obstacle detection processing 41. It is found that there is an obstacle in the rear image 224, and the central control module 32 can combine the warning signal 510 in the form of a prompt frame to the region of the bird's-eye image 320 corresponding to the rear image 224 to remind the driver to watch.

[0031]

In addition, the vehicle image security system of the present invention can also improve the convenience of function updating and reduce the update cost, which will be described below in the second embodiment.

[0032]

Please refer to FIG. 3, which is a block diagram of a second embodiment of a vehicle image security system according to the present invention. Please note that for the sake of clear display and ease of understanding, FIG. 3 only shows the main difference between the second embodiment and the first embodiment. Therefore, although the view conversion image and the superimposed image are not shown in FIG. 3 However, its function can still be implemented on the second embodiment.

[0033]

The main difference between the second embodiment and the first embodiment is that the first image processing unit 53 of the camera module 11 of the second embodiment can perform various image detection processes, including obstacle detection processing 41 and road bias. The motion detection processing 42, the moving object detection processing 43, the rear side vehicle detection processing 44, and the left and right blind area detection processing 45. The central control module 32 can generate different control signals 310 according to the moving speed of the mobile vehicle 7, the left and right direction signal, the steering wheel rudder angle or the driving position to control the first image processing unit 51 to execute different images. The detection process or a combination thereof produces a different alert signal 510. The following moving speed 71 and driving gear 72 are exemplified.

[0034]

For example, when the moving speed 71 of the mobile vehicle 7 exceeds a threshold value, for example, 30 kilometers per hour, the central control module 32 can control the first image processing unit 51 to perform the road offset detecting process 42. When the first image processing unit 51 detects from the rear image 224 that the mobile vehicle 7 has an offset lane, an alert signal 510 is generated.

[0035]

When the driving position 72 of the mobile vehicle 7 is the reverse gear, the central control module 32 can control the first image processing unit 51 to perform the obstacle detecting process 41. When the first image processing unit 51 detects an obstacle from the rear image 224, an alert signal 510 is generated. In addition, when reversing, the first image processing unit 51 combines the execution of the moving object detection processing 43 or the rear side vehicle detection processing 44 according to the design or its computing capability, thereby providing the driver with more security protection when reversing.

[0036]

Similarly, when the moving speed 71 of the mobile vehicle 7 is lower than the threshold and the driving position 72 is not the reverse gear, the central control module 32 can control the first image processing unit 51 to perform the moving object detecting process 43 or the left and right blind spots. Detection processing 45.

[0037]

It should be noted that the image detection processing that can be performed by the first image processing unit 53 is not limited to the above example, and different image detection processing can be performed according to the installation position, for example, including Blind Spot Warning. Or forward collision detection processing.

[0038]

The second embodiment has the advantage that only the camera module 10 needs to be replaced with the camera module 11, and the control firmware in the central control module 32 is updated, so that the central control module 32 can transmit the driving related information of the mobile vehicle 7. The data is given to the camera module 11 to increase the image security function of the mobile vehicle 7. Compared with the prior art, the hardware and software of the central control module 32 must be replaced. This creation only needs to replace one camera module to achieve the function update, that is, to improve the update convenience and reduce the update cost.

[0039]

Please refer to FIG. 4, which is a block diagram of a third embodiment of the vehicle image security system according to the present invention. The main difference between the third embodiment and the first embodiment is that the central control module 33 of the third embodiment further includes a second image processing unit 52, which can also perform the obstacle detection process 41. Therefore, if the computing capability of the camera module 10 is insufficient and the obstacle detection result cannot be calculated immediately, the camera module 10 can transmit the rear image 224 to the central control module 32, and the second image processing unit 52 performs a portion. Obstacle detection processing. In other words, the obstacle detection function of the overall action vehicle 7 is implemented by the first image processing unit 51 and the second image processing unit 52.

[0040]

In addition, the second image processing unit 52 may perform other image detection processing according to the left image 221, the right image 222, the front image 223, or the rear image 224, such as road offset detection processing, moving object detection processing, Left and right blind spot detection processing, front collision detection processing or vehicle detection processing on the rear side.

[0041]

Please refer to FIG. 5, which is a block diagram of a fourth embodiment of a vehicle image security system according to the present invention. In the figure, the fourth embodiment is different from the third embodiment in that the first image processing unit 51 and the second image processing unit 52 respectively perform different image detection processes. When the moving speed of the mobile vehicle exceeds the threshold, the first image processing unit 51 performs the road offset detecting process 42, and the second image processing unit 52 performs the left and right blind spot detecting process 45. When the action carrier is reversed, the first image processing unit 51 performs the obstacle detection process 41, and the second image processing unit 52 performs the rear side vehicle detection process 44.

[0042]

In summary, the photographic image security system of the present invention includes a first image processing unit 51 and a second image processing unit 52, which can perform the same image detection processing according to a distributed computing mechanism; or both Perform different image detection processes separately.

[0043]

In addition, the second image processing unit 52 can also perform image detection processing on the angle-of-view conversion image output by the camera module 10, the image processed by the display range, or the image processed by the display range and converted by the angle of view.

[0044]

In addition, in another embodiment, the vehicle image security system may also include a plurality of camera modules 11 and a central control module 32. The central control module 32 selectively combines the images according to the images captured by the plurality of camera modules to generate a bird's-eye image 320 and outputs the image to the display screen 60, or combines the bird's-eye image 320 with the plurality of warning signals 510.
