The invention relates to a wireless Internet of vehicles and things positioning system. The positioning system includes a plurality of vehicles and a plurality of street lamps arranged at roadsides; each street lamp is provided with a microprocessor, a first LTE communication module, a memory for storing street lamp geographic positions, a signal modulator, a first spreading code generator, a spread spectrum modulator, a first photoelectric signal converter and an LED light source; the LED light source is uniformly provided with a plurality of individually-numbered square LED light emitting lattices; black light LEDs, blue light LEDs, green light LEDs and red light LEDs are arranged in the light emitting lattices; each vehicle is provided with a central processor, a Bluetooth module, a second LTE communication module, a GPS positioning module, a positioning signal identification generator, an optical signal intensity detector, an optical signal receiver, a noise filtering device, a signal comparator, a second photoelectric signal converter, a spread spectrum demodulator, a second spreading code generator, a signal demodulator, a camera and a display screen. With the system adopted, the locations of the vehicles can be obtained by means of the optical signals of the street lamps and the positioning data of nearby vehicles.
