Description
Technical Field
The present disclosure relates to, but not limited to, image processing technologies, and in particular, to an information processing method, an information processing apparatus, a computer storage medium, and a terminal.
Background
The analysis of the activity state of the animals is an important basis for analyzing and managing the animals; the method comprises the following steps: expelling or killing certain animals in some areas based on the analysis of the animal's activity status; and (3) formulating and adjusting a breeding plan of the animals based on the activity state analysis of the animals.
In the catering industry, technicians check and control the activity of the rats after acquiring video data through a preset image acquisition device; for example, recorded video data is obtained in real time through a monitoring camera in a kitchen of a restaurant, health detection personnel of related departments manually check video contents according to a certain period, and whether rodent activities exist is determined by combining the scene of the kitchen; when the mouse movement which easily causes the sanitation hidden trouble is determined, the mouse is cleared by arranging the trap.
Because the mice are small and have secret activities, omission easily occurs by a method of manually checking video data and combining site investigation, and particularly, the omission is more easily caused when the mice with small volume are used; in addition, the method for manually checking the video data wastes time and labor in the checking process due to the redundancy of the video data. Taking the kitchen as an example: in areas where a large amount of food materials such as five cereals, meat products, vegetables and the like are stored, rats often do not work in the kitchen, and do activities such as crawling, sniffing, gnawing and the like on kitchen ware, tableware and food materials, so that sanitation and safety problems such as damage to kitchen appliances, pollution to food materials and the like are caused. According to a certain period, the recorded video data is checked by workers, and by combining with on-site investigation, partial mouse activity areas are likely to be determined, but the mouse activity areas are often determined not timely enough and a large amount of manpower is consumed, the problem that the mouse activity areas are missed by the workers who check the video data for a long time is easily caused, the efficiency of the mice in a long-term clear control process is low, and the food safety problem cannot be effectively controlled. The action of the mouse cannot be effectively controlled for a long time, thereby causing more serious food safety accidents.
In conclusion, the analysis of the activity state of the mouse cannot be accurately and efficiently realized by the staff in a manual mode, the control of the mouse activity is influenced, and the food sanitation and safety are influenced.

when the current activity area of the rodent is smaller than a pixel area of 3 by 3 within 5 seconds, determining that the rodent is in a gnawing state in the current activity area;
and when the current activity area of the mouse is smaller than the pixel area of 10 times 10 within 10 seconds, determining that the mouse is in a hot spot activity state in the current activity area.
Based on the activity information in table 3, the present application example can insert the determination result of the activity status in table 3 to form the content in table 4, and in table 4, the gnawing status and the hot spot activity status are exemplified as the activity status:
