Embodiment 1

[0025] An embodiment of the present invention provides a target object recognition method, such as figure 1 shown, including:

[0026] Step S10: Obtain the target trajectory of the target object, the target trajectory includes the latitude and longitude of the target object at different times.

[0027]In a specific embodiment, the target object may be, for example, a pedestrian who needs to be identified. When obtaining the target trajectory of the target object, it is possible to obtain the trajectory within a longer period of time as much as possible. The longer the time period, the more obvious the law of the acquired target trajectory, and thus the easier it is to identify the target object.

[0028] In the embodiment of the present invention, the target trajectory includes the latitude and longitude of the target object at different times, because the trajectory at different times will interfere with the identification of the target object, so the target trajectory obta...

Embodiment 2

[0058] Embodiments of the present invention provide a target object recognition device, such as Figure 4 shown, including:

[0059] The trajectory acquisition module 10 is configured to acquire the target trajectory of the target object, the target trajectory includes the latitude and longitude of the target object at different times, for detailed description, see the description of step S10 in the first embodiment above.

[0060] The latitude and longitude grid determination module 20 is configured to divide the target area where the target trajectory is located into multiple latitude and longitude grids of the same size. For a detailed description, refer to the description of step S20 in the first embodiment above.

[0061] The frequency calculation module 30 is used to determine the frequency of the target object appearing in each latitude and longitude grid in different time periods according to the latitude and longitude of the target object at different times. For a det...

Embodiment 3

[0080] An embodiment of the present invention provides a computer device, such as Figure 7 As shown, the computer device mainly includes one or more processors 61 and memory 62, Figure 7 A processor 61 is taken as an example.

[0081] The computer device may also include: an input device 63 and an output device 64 .

[0082] Processor 61, memory 62, input device 63 and output device 64 can be connected by bus or other ways, Figure 7 Take connection via bus as an example.

[0083] The processor 61 may be a central processing unit (Central Processing Unit, CPU). The processor 61 may also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), field-programmable gate arrays (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or combinati...

Abstract

The invention provides a target object identification method and device, and the method comprises the steps: obtaining a target track of a target object, wherein the target track comprises the longitude and latitude of the target object at different moments; dividing a target area where the target track is located into a plurality of longitude and latitude grids with the same size; determining thefrequency of the target object appearing in each longitude and latitude grid in different time periods according to the longitude and latitude of the target object at different moments; generating atarget trajectory matrix according to the frequency of the target object appearing in each longitude and latitude grid in different time periods; and determining the identity of the target object according to the target trajectory matrix and a preset travel library, wherein the preset travel library comprises a plurality of pre-stored travel trajectories and identity information corresponding to each pre-stored travel trajectory. By implementing the method, the identity of the target object can be determined through the target track, and the target track matrix is flexibly determined through the target track so that the identity of the target object can be determined more accurately.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a target object recognition method and device. Background technique [0002] In the existing technical solutions, the identity of the target object is usually obtained based on image recognition. For example, the face image of the target object collected on-site can be compared with the pre-stored face image, and according to the face image of the target object The identity information corresponding to the pre-stored face image closest to the image can determine the identity of the target object; it can also analyze the behavior and posture of the target object collected on the spot, and artificially determine the identity information of the target object through behavior posture. However, obtaining the identity information of the target object through face image recognition depends on relatively clear image data, and it is difficult to obtain a clear facial image in an e...
