Problems solved by technology

Due to morphological changes or local occlusions during the movement of the target, when there are deformations, features are occluded, or multiple types of targets, the simple method of extracting the local features of the target often cannot accurately count the number of targets in the area.
In addition, in the method of video counting, there is a problem of double counting in the process of processing multiple frames of pictures

Embodiment 1

[0044] like figure 1 , The present embodiment provides a method of identifying the number of images based on statistics, comprising the steps of:

[0045] S0: acquiring a video image and extracts a key frame of a video image in order to get to be counted area image; video image of each camera target number of statistical areas taken by obtaining the respective entrances, links or need, and a video image extracting key frames, and then pretreatment;

[0046] S1: acquiring statistical area to be counted to be in a region of the image area 2 and the reference count, the reference count region 2 to be located within a region statistics; step S1, the reference statistical horizontal or vertical region 2 through the region 1 to be counted, the reference statistical region 2 comprises a first edge, a second edge and the shaded area, the shaded region is located between the first and second edges; as figure 2 3 which is a moving object shown in a schematic diagram, the direction of the ar...

Embodiment 2

[0056] Embodiment 2 discloses an electronic device including a processor, a memory, and a program, wherein the processor and the memory can be used, and the program is stored in the memory and is configured by the processor, When the processor executes the program, the method of image recognition based on image recognition is implemented. The electronic device can be a series of electronic devices such as mobile phones, computers, tablets.

Embodiment 3

[0058] Embodiment 3 discloses a readable computer storage medium for storing the program, and when the program is executed by the processor, the number of image identification based on image recognition is implemented.

Abstract

The invention discloses a counting method based on image identification, which includes an acquisition step and a calculation step. In the acquisition step, a to-be-counted region and a reference counting region of a to-be-counted region image are acquired, wherein the reference counting region is in the to-be-counted region. In the calculation step, the directions in which all targets pass through the reference counting region and the number of targets corresponding to each direction are calculated. The invention further discloses a piece of electronic equipment, a computer readable storage medium, and a counting device based on image identification. According to the counting method based on image identification of the invention, the targets are counted by setting the reference counting region for covering purpose and making judgment, and the accuracy of counting is greatly improved. The targets can be counted, and whether a target is entering or leaving can be determined by judging the direction. The method and the device have more extensive application value.

Description

Technical field [0001] The present invention relates to an image recognition technique, and more particularly, to a method and an apparatus statistical quantity based on image recognition. Background technique [0002] Currently, shopping malls, museums, exhibition halls, stadiums and other public building entrances, escalators and corridors of buildings and other long channel access slot, up and down the passenger door passenger vehicle, entrances and other playground rides each place, often need to count at a time traffic point or period of time, the number of people entering and leaving, this is based on statistical data to optimize operations and improve management. [0003] Currently, using image recognition techniques based target number of statistical studies, mostly statistical approach target partial region or a combination of feature extraction, feature tracking method to track the multiple targets based counts. Or morphological changes due to partial occlusion, the pre...
