The invention discloses an action scope intersection detection method and a device for action scope intersection detection, and relates to the field of action scope intersection detection. The action scope intersection detection method includes: acquiring a position of a detection point in a mobile action scope in each physical frame; connecting positions of the detection point in a mobile action scope in adjacent physical frames to form a path line segment; determining if the path line segment is intersected with a target action scope or not, determining that the mobile action scope is intersected with the target action scope if so. According to the invention, discrete detection points are processed continuously, action scope intersection detection is performed on the target action scope according to the path line segments acquired by continuous processing, and the detection method and device are independent of the frame rate and can accurately detect an action scope intersection event in the situation that the action scope moves at a high speed or the system frame rate is low.
Description
technical field [0001] The invention relates to the field of scope intersection detection, in particular to a scope intersection detection method and a device for scope intersection detection. Background technique [0002] In the prior art, the scope intersection detection of the mobile scope is mainly based on the detection of points on the mobile scope, that is, the position of the detection point on the mobile scope in each physical frame and the judgment area of the target scope When the relationship is processed and detected, if and only when the detection point enters the judgment area of the target scope, it is judged to generate a scope intersection event. [0003] When scopes are moving at high speed or the system frame rate is low, it may happen that scope intersections are not accurately detected. Such as figure 1 As shown, the move scope 12 moves along a straight line and passes through the target scope 14 . The detection point Af1 and the detection point ...
