[0033] like figure 1 As shown, a method for detecting a moving object in the first embodiment of the present invention is applied to a mobile terminal, including:

[0034] Step 101, acquiring the first frame of target image data and the second frame of target image data collected by the camera at different times.

[0035] After the camera of the mobile terminal is started, image data within its shooting range can be acquired in real time. In this step, two frames of target image data collected by the camera at different times are used as basic data for moving object detection. Wherein, the target image data of the first frame and the target image data of the second frame can be adjacent frame images, and can also respectively take the Nth frame and the N+nth frame after the camera is started, n=1, 2, 3..., In order to ensure real-time detection, the value of n should be smaller than a threshold.

[0036] Step 102: Generate frame difference image data based on the first fram...

[0134] Figure 10 It is a schematic structural diagram of a mobile terminal according to another embodiment of the present invention. Figure 10 The mobile terminal 1000 shown includes: at least one processor 1001 , a memory 1002 , at least one network interface 1004 , a user interface 1003 and a camera 1006 . Various components in the mobile terminal 1000 are coupled together through the bus system 1005 . It can be understood that the bus system 1005 is used to realize connection and communication among these components. In addition to the data bus, the bus system 1005 also includes a power bus, a control bus and a status signal bus. But for clarity, in Figure 10 The various buses are denoted as bus system 1005 in FIG.

[0135] Wherein, the user interface 1003 may include a display, a keyboard, keys or a pointing device (for example, a mouse, a trackball (trackball), a touch panel or a touch screen, and the like.

[0136] It can be understood that the memory 1002 in thi...

Abstract

The invention provides a movement object detection method and a mobile terminal, and relates to the communication technical field. The detection method comprises the steps of obtaining a first frame target image data and a second frame target image data collected by a camera at different moments; generating a frame difference image data based on the first frame target image data and the second frame target image data; performing binaryzation processing on the frame difference image data to generate a binaryzation image data; performing opening-algorithm processing on the binaryzation image data to generate a target image data; and generating a detection result of the movement object based on the target image data. By adoption of the scheme, the problem of misjudgement on movement caused by shaking when the mobile terminal is hand held in the prior art is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for detecting a moving object and a mobile terminal. Background technique [0002] With the development of technology, mobile terminals are not limited to basic communication functions, but also add many auxiliary functions to meet the needs of users and bring great convenience to people's lives. Among them, the photographing function is an important auxiliary function, and its photographing technology is no less than that of some cameras, and because the mobile terminal is smaller in size and more convenient to carry, it is loved by more and more people. [0003] In order to further improve the photographing function of the existing mobile terminal, the detection of moving objects is also added in the photographing function to increase its practicability. For example, in the state of automatically taking pictures, the mobile terminal can determine whether to tak...
