Abstract
An object counting method having route distribution property is applied to an image processing device. The object counting method includes steps of recording an initial position datum and a final position datum of any object moving within an image frame, setting at least one detection line inside the image frame, determining whether a connection line between the initial position datum and the final position datum moves across the detection line, and drawing an object distribution diagram by relation between an amount of the object moving across the detection line and its detective period.

An object counting method having route distribution property, the object counting method comprising:
- recording an initial position datum and a final position datum of any object moving within an image frame;
- setting at least one detection line inside the image frame;
- determining whether a connection line from the initial position datum to the final position datum of each object moves across the detection line;
- and
- drawing an object distribution diagram by relation between an amount of the object having the connection line moving across the detection line and every point of time in a movement of the object.
An image processing device having route distribution property, the image processing device comprising:
- an image producer adapted to capture an image frame;
- a display adapted to display the image frame;
- and
- an operational processor electrically connected to the image producer and display, the operational processor being adapted to record an initial position datum and a final position datum of any object moving within an image frame, to set at least one detection line inside the image frame, to determine whether a connection line from the initial position datum to the final position datum of each object moves across the detection line, and to draw an object distribution diagram by relation between an amount of the object having the connection line moving across the detection line and every point of time in a movement of the object.
