[0002] At present, when police officers perform official duties, they monitor the surrounding environment in the police car. Most of them use naked eyes to observe. The human body sits in the cab. omission; a small number of police vehicles are equipped with rotatable cameras or multiple cameras, but the rotatable cameras, like the human eye, cannot observe the pictures in each direction of the car body at the same time, and the police vehicles with multiple cameras Cars, due to the limited shooting range of the camera, it is easy to produce dead angles, and the images captured by multiple cameras need to be displayed on the display screen through multiple screens, which is easy to cause visual fatigue

Embodiment
[0037] Example: see Figure 1 to Figure 3 , the present embodiment provides a police vehicle monitoring method without dead angle, which includes the following steps:
[0038] (1) A shooting device is set, which includes a wide-angle lens and a CMOS image sensor;
[0039] (2) An interactive terminal is set, and the interactive terminal is arranged in the car, and the interactive terminal includes an operation unit, a storage module, a wireless network transceiver module and a display;
[0040] (3) A DSP processing module and a GPS positioning module are set in the interactive terminal, and the DSP processing module exchanges information with the photographing device, display, storage module, wireless network transceiver module and GPS positioning module;
[0041] (4) When working, the shooting device shoots the surrounding environment of the car body, and transmits the original real-time image information of wide viewing angle and distortion to the DSP processing module; the ...

The invention discloses a dead-corner-free vehicle monitoring method for police. The monitoring method is characterized by comprising the following steps that 1, shooting devices are arranged; 2, an interaction terminal is arranged in a vehicle; 3, a DSP module and a GPS module are arranged in the interaction terminal; 4, during work, the shooting devices shoot the surrounding of a vehicle body and transmit distorted original image information with wide view angles to the DSP module; the DSP module processes the image information obtained by the shooting devices, carries out distortion correction and image reconstruction, splices images collected by the shooting devices, displays an integral panoramic image surrounding the vehicle body after splicing on a display screen through a frame, and meanwhile converts the image information into a digital signal to be stored, called and checked in a later stage or remotely. The invention further discloses a monitoring system for implementing the method.
Description
technical field [0001] The invention relates to the field of police monitoring, in particular to a vehicle-mounted police monitoring method without blind spots, and a monitoring system for implementing the method. Background technique [0002] At present, when police officers perform official duties, they monitor the surrounding environment in the police car. Most of them use naked eyes to observe. The human body sits in the cab. omission; a small number of police vehicles are equipped with rotatable cameras or multiple cameras, but the rotatable cameras, like the human eye, cannot observe the pictures in each direction of the car body at the same time, and the police vehicles with multiple cameras For cars, due to the limited shooting range of the camera, it is easy to produce dead angles, and the images captured by multiple cameras need to be displayed on the display screen through multiple screens, which is easy to cause visual fatigue.
