Embodiment 1

[0035] Such as figure 1 The shown a kind of reversing camera dynamic detection method of the present invention comprises the following steps:

[0036] (1) the digital signal processing to the image information of collection is video signal, can adopt existing reversing camera to carry out the collection of image information among the present invention, and image information is in the range of 10m (wide) * 5m (long) behind the car image;

[0037] (2) converting the video signal into a clear display signal in an encoding format;

[0038] (3) Extracting the motion information in the video signal in addition, obtaining the motion information of all moving objects in the image information;

[0039] (4) Finally, the motion information is converted into a motion signal, and the motion signal is a relatively easy-to-distinguish signal that plays a warning role, and is used to remind the user that there is a moving object behind the car, and the display signal and motion information ...

Embodiment 2

[0049] A camera dynamic detection system for reversing, such as Figure 5As shown, it includes an image processing module 1, a video decoding module 3 and a motion information display module 4 connected in sequence, and the output end of the image processing module 1 is also connected with a motion information extraction module 2, and the motion information extraction module 2 and motion information The information display module 4 preferably adopts an MD image processor, but is not limited thereto, and other processors that can be implemented can also be used. The video decoding module 3 can adopt a conventional video decoder, and the output of the motion information extraction module 2 Terminal is connected with described sports information display module 4;

[0050] The image processing module 1 processes the image information digital signal collected into a video signal, and then sends it to the video decoding module 3, and the video decoding module 3 sends to the motion i...

Abstract

The invention relates to a vehicle-reversing camera dynamic-detection system and a vehicle-reversing camera dynamic-detection method. The method comprises the following steps: (1) processing the digital signal of a collected image information into a video signal; (2) carrying out encoding format conversion on the video signal to generate a display signal; (3) additionally extracting the motion information in the video signal; (4) finally converting the motion information into a motion signal, incorporating and displaying the display and motion signals together. The invention is mainly applied to the monitoring of the passing vehicles and pedestrians when a vehicle is parked by the roadside and the door is opened, and enables the driver to become aware of the moving object behind the vehicle more intuitively so as to perform the warning function. Therefore, the driver can know whether the object moves quickly or slowly by such a color increment difference.

Description

technical field [0001] The invention relates to a dynamic detection system and method of a reversing camera, belonging to the technical field of reversing images. Background technique [0002] The motion detection function was independent of the monitoring system in the early days, and was only responsible for monitoring and alarming the image changes in a specific area on the display screen. The images collected by the camera according to different frame rates will be calculated and compared by the CPU according to a certain algorithm. When the picture changes, if someone walks by and the lens is moved, the number obtained from the calculation and comparison result will exceed the threshold and indicate the system performance. Automatically make corresponding processing; in the automotive electronics industry, it is mainly used in traffic violation records and driving recorders. At present, this application is not popular in the automotive electronics industry. [0003] Mo...
