Detailed description of the invention

In view of the tradition insufficiency of function remained static that utilizes infrared ray, ultrasound sensors only can be applicable to another object, driving Man's Demands cannot be met, therefore the utility model design can closely connect the detecting warning device of dynamic object by this in travelling, the object clearly detecting high-speed mobile around steering vehicle significantly can promote travel safety.

The utility model is by the real time status using digitized video comparison identification can learn rapidly and precisely dynamically object around, traditional design then uses AV image to compare identification, therefore speed is comparatively slow and the hardware space of larger capacity need be spent real be inconvenience, also between running at high speed, cannot precisely provide warning message immediately.Moreover, use digitized video capture device except above advantage, also can because of high and easy to use with the compatibility of controller, no matter the picture number number of digitized video capture device all can be compatible with controller, to meet the main points of modern's digital living.

The concrete technology that the utility model adopts, will be further described by following examples and accompanying drawing.

Refer to shown in Fig. 1 and Fig. 2, wherein show the circuit function diagram of block that the utility model closely connects the detecting warning device of dynamic object, and Fig. 2 shows the schematic diagram of the utility model connected applications when a locomotive.As shown in the figure, the detecting warning device 100 closely connecing dynamic object of the present utility model includes the rear position that at least one image capturing device 1 is configured in a carrier A, the real-time imaging M of in order to capture the rear position of this carrier A one dynamic object C.This carrier A can be one of any carriers such as a locomotive, bicycle, automobile.

One image conversion unit 2 is connected to this image capturing device 1, in order to receive this real-time imaging M that this image capturing device 1 captures, and every a sampling range (such as 1 second), this real-time imaging M is being sampled, and obtain a plurality of digital forms image data S1, S2, S3 ... Sn.Combine by a plurality of pixel cell the appearance profile M1 forming this dynamic object C in each this digital forms image data S1.

Fig. 3 shows in first digit pattern image data S1 by a plurality of pixel cell S11, S12, S13 ... S1n; By a plurality of pixel cell S21, S22, S23 in second digit pattern image data S2 ... S2n; By a plurality of pixel cell S31, S32, S33 in third digit pattern image data S3 ... S3n; By a plurality of pixel cell Sn1, Sn2, Sn3 in N number of digital forms image data Sn ... Snn.Fig. 4 shows the schematic diagram that digital forms image data is made up of a plurality of pixel cell.One image apparatus for temporary storage 3 is connected to this image conversion unit 2, in order to store this digital forms image data S1, S2, S3 that this image conversion unit 2 produces ... Sn.

One pixel comparing unit 4 receives this digital forms image data S1, S2, S3 of storing in this image apparatus for temporary storage 3 ... Sn, and this digital forms image data S1, S2, S3 of more than at least two before and after comparison ... Sn.

As shown in Figure 4, when being configured with the carrier A closely connecing the detecting warning device 100 of dynamic object of the present utility model and advancing along a road B, if when image capturing device 1 captures the dynamic object C of carrier A rear position with identical speeds, the quantity of the pixel cell of this digital forms image data that the quantity then sampling the pixel cell of the digital forms image data obtained each time can obtain with front primary sample is identical, namely represents that the dynamic object C at rear there is no the action of overtaking other vehicles.Meanwhile, the quantity of the pixel cell of this digital forms image data that the quantity that image capturing device 1 captures the pixel cell of the digital forms image data of the background object D (such as road tree) of carrier A rear position can obtain than front primary sample is little.Namely pixel comparing unit 4 ignores this background object D.

And when rear position at a relatively high speed close to carrier A of the dynamic object C at rear, the quantity of the pixel cell of this digital forms image data (such as S2) that the quantity that image capturing device 1 captures the pixel cell of the digital forms image data (such as S3) of dynamic object C can obtain with front primary sample is large (as shown in Figure 5), namely sends alarm signal 41 to alarm unit 5 and sends warning.

And when the dynamic object C at rear overtakes other vehicles at a relatively high speed, the quantity of the pixel cell of this digital forms image data (such as S2) that the quantity that image capturing device 1 captures the pixel cell of the digital forms image data (such as S3) of dynamic object C can obtain with front primary sample is large and is offset to a wherein direction (as shown in Figure 6,7), also sends alarm signal 41 to alarm unit 5 and sends warning.This alarm unit 5 can be a luminescence component 51, also can be a sounding component 52.

Above illustrated embodiment is only in order to illustrate the utility model, and be not used to limit scope of the present utility model, under all other do not depart from the spirit that the utility model discloses, the equivalence that completes is modified or displacement, all should be contained in the scope of the claims of the utility model application.
