Embodiment 1
[0052] Embodiment 1, this embodiment proposes a bus congestion calculation method based on video analysis, such as figure 1 shown, including the following steps:
[0053] S1. Obtaining monitoring video image information in the bus;
[0054] S2, using the frame difference method to detect the coverage area in the middle and rear of the carriage, and counting the ratio of the coverage area in the middle and rear of the carriage to the middle and rear of the carriage;
[0055] S3, using the gradient method to detect the coverage area at the front of the compartment, and counting the proportion of the coverage area at the front of the compartment to the front of the compartment;
[0056] S4. Judging the degree of congestion of the bus according to the ratio of the coverage area at the middle and rear of the carriage to the middle and rear of the carriage and the ratio of the coverage area at the front of the carriage to the front of the carriage.
[0057] Among them, the camera in...

The invention discloses a bus congestion degree calculation method based on video analysis, which comprises the following steps: (1) Obtaining monitoring video image information in the bus; (2) Using the frame difference method to detect the coverage of the middle and rear parts of the carriage Area, counting the proportion of the coverage area of the middle and rear of the carriage to the middle and rear of the carriage; (3), using the gradient method to detect the coverage area of the front of the carriage, and counting the proportion of the coverage area of the front of the carriage to the front of the carriage; (4) 1. Judging the degree of bus congestion according to the ratio of the coverage area of the middle and rear of the carriage to the middle and rear of the carriage and the ratio of the coverage of the front of the carriage to the front of the carriage. The bus congestion degree calculation method based on video analysis of the present invention obtains the bus congestion degree by image analysis, which is closer to the actual congestion degree, adopts pure video analysis, saves production and implementation costs; divides the detection area into small areas, rationalize the results.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for calculating bus congestion based on video analysis. Background technique [0002] In the current real-time bus dispatching scheme, it is mainly based on the real-time return position information of online vehicles. The back-end platform observes the distribution of vehicles before and after, and issues adjustment commands to online vehicles to achieve a reasonable distribution of buses within the line. However, for the peak and trough periods of passenger flow on the current line, it is still set through experience. In the off-peak period, it cannot actually solve the rational allocation of vehicles. [0003] The bus routes have always been set through artificial statistical analysis. The bus routes in most cities have not changed over the years. With the rapid development of the city, the number of citizens continues to increase. The currently ...
