Embodiment 1
[0029] First, refer to figure 1 An example electronic system 100 for implementing the shading ratio determination method, device and electronic system of the embodiments of the present invention will be described.
[0030] Such as figure 1 A schematic structural diagram of an electronic system is shown, the electronic system 100 includes one or more processing devices 102, one or more storage devices 104, input devices 106, output devices 108 and one or more image acquisition devices 110, these components The interconnections are via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.
[0031] The processing device 102 may be a gateway, or an intelligent terminal, or a device including a central processing unit (CPU) or other forms of proc...
Embodiment 2
[0038] This embodiment provides a method for determining an occlusion ratio, which is executed by the processing device in the electronic system; the processing device may be any device or chip with data processing capabilities. The processing device can independently process the received information, or can be connected with a server to jointly analyze and process the information, and upload the processing results to the cloud. Such as figure 2 As shown, the occlusion ratio determination method includes the following steps:
[0039] Step S202, acquiring an image to be processed;
[0040] The image to be processed can be intercepted from video data, extracted from a database, or obtained by shooting in real time. If the image is intercepted from video data, the image can also be called a video frame image; specifically, it can be obtained frame by frame from the video file according to the time sequence of each video frame, and each frame of the obtained video frame image c...
Embodiment 3
[0054] This embodiment provides another method for determining the occlusion ratio, which is implemented on the basis of the above-mentioned embodiments; in this method, the method of judging whether the detection area of the target object overlaps with the detection area of objects other than the target object is further described Specific ways; such as image 3 As shown, the method includes the following steps:
[0055] Step S302, acquiring an image to be processed;
[0056] Step S304, detecting the object in the image through a preset detection model to obtain the detection area of the object;
[0057] Step S306, judging whether there are multiple detected objects, if yes, execute step S308; if not, end;
[0058] In this embodiment, a corresponding occlusion ratio is determined for each detected object, and this scene is taken as an example for description. Based on this, each of the multiple objects may be determined as the target object one by one according to th...
