[0025] refer to figure 1 , the first embodiment of the boundary detection method of the traffic target in the present application, including:

[0026] S101: Obtain an image to be detected including a traffic target.

[0027] Traffic objects can be vehicles, pedestrians, or objects located in the traffic area. Traffic targets are, for example, objects such as cars and people walking on the road, or other movable or immovable objects on the road.

[0028] The image to be detected contains a traffic target, that is, the traffic target is displayed in the image. For example, the image to be detected including the traffic target may be captured by a camera device, a monitoring device, etc. installed in a corresponding traffic area. For example, a mobile terminal, such as a mobile phone, a law enforcement recorder, a digital camera, etc., may also be used to capture images to be detected including traffic targets. Of course, it may also be an image to be detected obtained from o...

Abstract

The application discloses a boundary detection method, equipment and device for a traffic target, wherein the detection method includes: acquiring an image to be detected including a traffic target; performing boundary detection on the traffic target in the image to be detected to obtain a pre-detection area; The boundary point probability spectrum of the pre-detection area is calculated along different directions on the grayscale image of the pre-detection area; the boundary point probability spectrum in at least two directions intersecting with each other is fused to obtain the fusion probability spectrum; further boundary is performed on the fusion probability spectrum Detect to distinguish the shadow area and the target area in the pre-detection area, so as to obtain the boundary coordinates of the target area. Through the above method, the present application can improve the detection accuracy of traffic objects in the image.

Description

technical field [0001] The present application relates to the technical field of image detection, in particular to a boundary detection method, equipment and device for traffic objects. Background technique [0002] Image detection is an important technical part of image recognition technology, and it is widely used in the current transportation, living and industrial fields. In the traffic field, traffic areas need to be monitored and traffic objects need to be extracted, so the boundary detection of traffic objects is very important, that is, image detection technology has great uses and markets in the detection of traffic objects. The current image detection technology is not accurate enough to be applied to the detection of traffic targets. Contents of the invention [0003] The technical problem mainly solved by this application is to provide a boundary detection method, equipment and device for traffic objects, which can improve the detection accuracy of traffic obj...
