Provide a kind of radio car backing designating system based on this reason the utility model, after allowing user see car in image, according to real-time backing track line can be accurately, guided vehicle is implemented reversing objectively, realizes in addition transmission over radio, makes to install simpler, practical and convenient.
Summary of the invention
Task to be solved in the utility model is to realize a kind ofly can showing that reverse image follows the radio car backing designating system of backing track line, first by the graphicinformation of wireless transmission camera, be presented at mobile terminal, simultaneously by transmission over radio steering wheel angle information, calculate actual backing track leading line according to steering wheel angle information, then utilize camera model to be plotted on image.
The utility model is achieved through the following technical solutions
.
This radio car backing designating system comprises: camera, wheel steering information acquisition unit and mobile display terminal.
Described camera comprises image unit, processing unit, radio network unit one.
Described wheel steering information acquisition unit comprises steering wheel sensor, OBD interface, radio network unit two.
Image information when described image unit collection reversing after car, and be connected with processing unit.
Described processing unit is connected with the output port of image unit, the image information that image unit is provided compresses processing, and be connected with radio network unit one, processing unit will be transferred to the radio network unit one in camera after data packing after treatment compression.
Radio network unit one in described camera is connected with the output port of processing unit, the video information after the packing of reception & disposal cell compression, and be connected by wireless with mobile display terminal.
Described steering wheel sensor is connected with OBD interface, detects the angle of bearing circle, sends the angle information of bearing circle to OBD interface in real time.
Described OBD interface is " On-Board Diagnostics (OBD) ", be connected with the output port of steering wheel sensor, receive direction dish angle information, and being connected with radio network unit two, OBD interface by communication to the radio network unit two in wheel steering information acquisition unit.
Radio network unit two in described wheel steering information acquisition unit is connected with the output port of OBD interface, and is connected by wireless with mobile display terminal.
Described mobile display terminal is portable wireless terminal (as smart mobile phone, pad etc.), is connected by wireless with radio network unit one, radio network unit two respectively, and the information that its reception radio network unit one and radio network unit two provide.
Finally, mobile display terminal utilizes APP software to process the information receiving, show reverse image, show two real-time backing track leading lines simultaneously, two described backing track lines, the angle information that is the bearing circle by receiving calculates, and then utilizes camera model to be plotted on image.
The beneficial effects of the utility model are:
The first, owing to adopting the mode of operation of transmission over radio, make camera, wheel steering information acquisition unit and display equipment directly use wireless connections, solved the problem that traditional wiring is loaded down with trivial details, cost is high.
