Turn signal callback method according to an embodiment of the invention, wherein, the data processing equipment is right When the image of described image harvester collection carries out the contour extraction processing, the energy of image is calculated first, wherein,For custom parameter, value range 0-1,Put down for image outline inside Equal gray value,For average gray value outside image outline,For averaged curve function,, WhereinFor custom parameter;Then the maximum of image energy is asked for, is calculated with thisValue, finally energy is reached most Big image zooming-out profile.

Brief description of the drawings

Fig. 1 is the schematic diagram of all parts in a kind of turn signal callback method of the invention.

Embodiment

Turn signal callback method of the present invention is described in detail with reference to the accompanying drawings and examples.

The present invention provides a kind of turn signal callback method, and vehicle turn signal is automatically closed during straight-line travelling, Therefore, the present invention utilizes initialization step, driving path image acquisition step, driving path image procossing, analytical procedure, steering Lamp closes step, and during its straight line traveling, vehicle turn signal is automatically closed.

As shown in Figure 1, turn signal readjustment system includes:Driving path test module, steering indicating light call-back device, control Device and trigger circuit;

Driving path test module includes image collecting device and data processing equipment, wherein, image collecting device is installed on car Front end, image collecting device are used for collection vehicle front-end image signal, and picture signal is transmitted to number in the process of moving According to processing unit, data processing equipment carries out picture signal denoising, contour extraction processing, and the picture signal after processing is passed Transport to control device, by the picture signal after processing judge vehicle whether straight-line travelling, if straight-line travelling, then control device Indicate that trigger circuit produces low level trigger signal, and the low level trigger signal is transmitted to the steering indicating light readjustment dress Put, steering indicating light call-back device extinguishes vehicle left steering lamp and right turn lamp, if not straight-line travelling, then trigger circuit does not produce Trigger signal;

Turn signal callback method comprises the following steps:

Step 1:Initialization step, control device connects driving path test module respectively by serial communication line, steering indicating light returns Device and trigger circuit, the driving path test module is adjusted to include image collecting device and data processing equipment, described image Harvester is installed on the front of the car;

Step 2:Driving path image acquisition step, the control device control described image harvester gather the vehicle and exist Front-end image signal during traveling, and described image signal transmission to the data processing equipment, the data processing are filled Put and denoising, contour extraction processing are carried out to described image signal;

Step 3:Driving path image procossing, analytical procedure, are transmitted to the control device by the picture signal after processing, pass through Picture signal after processing judge the vehicle whether straight-line travelling, if straight-line travelling, then described in the control device instruction Trigger circuit produces low level trigger signal, and the low level trigger signal is transmitted to the steering indicating light call-back device, and Step 4 is carried out, if not straight-line travelling, then repeats the above steps 2;

Step 4:Steering indicating light closes step, and the steering indicating light call-back device extinguishes the vehicle left steering lamp and right turn lamp.
