Specifically, the monitoring method of the anti-theft and anti-blocking monitoring device is that the picture data of the camera device 2 is continuously collected; comparing the picture data of the adjacent time intervals, and judging as a changed pixel point when the difference of any one color of the RGB color data of the corresponding pixel point in the two picture data of the adjacent time intervals is greater than a first preset threshold value;
will change the area that shared area of pixel and the area of the picture of camera device 2 shooting are compared, work as change pixel area and be greater than the first predetermined proportion of whole picture area and when lasting first predetermined time, judge as an unusual picture, will unusual picture transmits to control terminal, control terminal is visual operation platform or high in the clouds APP.
Taking a lens with a focal length of 1/3' CCD lens of 4mm as an example, the two-dimensional area of a common medium and small sized excavator in a construction site is about 4m2The monitoring lens is set to be 5m away from the monitoring site, and the excavator is set to be within 1-2m away from the monitoring site (relative to the straight line direction of the lens and the center of the monitoring site)And (4) calculating the abnormal movement ratio, namely the abnormal movement ratio is 6-14%, and the method can be characterized in that a small and medium-sized excavator enters the monitoring construction site within the range of 2 meters. In addition, the abnormal motion duration should be set to avoid the abnormal motion judgment of the vehicles and pedestrians passing through the lens in the short distance, and preferably set to be 5min according to experience.
The final logic judgment is as follows: when the change proportion of the image pixel points is 6-14% and the duration lasts for more than 5min, the suspected small and medium-sized excavators entering the monitoring site within 2m can be preliminarily judged, and the image is transmitted to the visual operation platform or the cloud APP.
For reducing the energy consumption as far as possible, camera device should possess resolution ratio intelligent regulation function, will change the area that the shared area of pixel and the area of the picture that camera device 2 was shot and still include after comparing, when change pixel area and be less than the second of whole picture area and predetermine the proportion and last the second predetermined time, control camera device 2's resolution ratio falls to between 270P-360P.
According to the above discussion, when the proportion of transaction is less than 5%, and the duration is 30min, the stay resolution reduction mode can be entered.
The monitoring method of the anti-theft and anti-shielding monitoring device further comprises the step of continuously acquiring the sensing distance measurement of the distance sensing device, when the sensing distance measurement of the distance sensing device is shortened to a third preset proportion of the original sensing distance measurement and lasts for a third preset time, a suspected intentional shielding behavior is judged, and by combining judgment of the picture abnormal movement proportion and the duration, misjudgment can be avoided. The determination should be based on the monitoring capability after the transaction. According to the actual monitoring content, when the shielding proportion is more than 30%, the monitoring capability is greatly reduced, so that the field monitoring requirement cannot be met. Therefore, when the picture abnormal ratio is larger than 30%, or the infrared distance measurement is shortened to 70% and lasts for 5min, it can be determined that there is a suspected intentional shielding behavior.
