Light and shade flicker is sent to mobile terminal 4.
The mobile terminal 4 of the present invention is the smart mobile phone with camera and preloaded system APP, and smart mobile phone passes through calling
Camera is handled collecting infrared LED light and shade flicker information, is resolved to location information and is positioned, seeks bus or train route diameter rule
It draws.
The present invention it is a kind of based on imaging communication underground parking lot position car searching method, using it is upper it is a kind of based on imaging communication
Vehicle system is sought in the positioning of underground parking lot, is specifically implemented according to the following steps：
Step 1, pre- cloth lamp is carried out in the parking lot of underground, specially：As shown in figure 3, at the top of the track in underground parking lot
The even multiple infrared LED lamps of arrangement, and precoding is carried out to each infrared LED lamp on controller 1；
Step 2, the precoding information of different location is sent to infrared LED lamp by controller 1 by power carrier, infrared
LED light carries out light and shade flicker according to coding, and binary zero be dark, and binary one is bright, flicker frequency 1/16hz, i.e. in 1s
Flicker 16 times, is lighted twice in first 8 times in 1s, is gone out entirely for six times, and the information of transmission is " 10 000 001 ", which is frame
Head, mobile terminal 4 just carry out position identification when only recognizing the frame head；Latter 8 times in 1s are the light and shade comprising coding information
Flicker；
Step 3, when parking, user picks up infrared LED of the mobile terminal 4 by camera scanning lamp for vehicle lane, obtains current
Parking position, and by location information storage to mobile phone caching in, as shown in Figure 4 when the user clicks navigation button when mobile phone camera
Initialization starts preview interface；To being intercepted from the collected video flowing of camera, the image of each frame is carried out at gray scale
Reason, judge that the pixel lighted in view-finder is then denoted as " 1 " for " bright " if more than given threshold, it is on the contrary then be " dark " be denoted as " 0 ".
When the frame originating point information " 10 000 001 " for correctly recognizing LED transmissions just carries out the identification of next step, otherwise continue with until
Correctly identify frame originating point information.
Step 4, when user picks up the car, the current location residing for it is picked up by the camera scanning lamp for vehicle lane of mobile terminal 4
