Method for monitoring whether taxi driver runs meter or not when carrying passenger

The invention relates to the technical field of communications, in particular to a method for monitoring whether a taxi driver runs a meter or not when carrying a passenger. The method includes the following steps: a camera collects the image information of the copilot position; a CPU grays the image information and uses a frame difference method to process the image information; after detecting the moving objective, the CPU accumulates the number of movements of the moving objective; the CPU rechecks the accumulated result, so as to effectively prevents mistakes. The monitoring terminal is simple in structure and highly reliable. With the data processing method used by the taxi-mounted monitoring terminal provided by the invention, the image information is grayed and processed by using the frame difference method; the number of movements of the moving objective after detected is accumulated and rechecked, so that mistakes are effectively prevented; the result after recheck is uploaded to the monitoring center by the CPU via a wireless communication unit and a mobile communication network.
