1 is a block diagram illustrating a configuration of an object counting apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an object counting apparatus includes a camera 100, a sensor unit 200, and an integrated control center 300.

The camera 100 may be a speed dome camera disposed at a fixed position in a specific space. The camera 100 may be a PTZ camera having a pan / tilt / zoom function. The camera 100 generates a live image which is an image of a specific place obtained by the PTZ function. The camera 100 continuously captures an image while rotating the body at a fixed position by panning from 0 to 360 degrees and tilting from -5 to 185 degrees so that the integrated control center 300 ).

The camera 100 receives the PTZ control signal from the integrated control center 300 and performs panning, tilting, and zooming in accordance with the PTZ control signal. The panning means that the camera 100 rotates in the horizontal direction, and the tilting means that the camera 100 rotates in the vertical direction.

In this embodiment, the camera 100 may include a first camera 100_1 to an Nth camera 100_N. Each of the first camera 100_1 to the Nth camera 100_N is disposed around the door of the entire space and the indoor space to be described later under the control of the integrated control center 300 to photograph the entry / Object coefficient information can be generated from the photographed image. Each of the first camera 100_1 to the Nth camera 100_N is disposed in an arbitrary area of an outdoor space to be described later under the control of the integrated control center 300 to capture an image, can do.

A detailed block diagram of such a camera 100 is shown in Fig. FIG. 2A is a detailed block diagram of a camera 100 according to an embodiment, and FIG. 2B is a detailed block diagram of a camera 100 according to another embodiment.

2A, the camera 100 includes a first image acquiring unit 110, a foreground / background separating unit 120, an object extracting unit 130, and a first object counting unit 140. The first image acquiring unit 110 acquires an image frame of a space in which the camera 100 is disposed using an image pickup device composed of a CCD (charge coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor. The foreground / background separator 120 separates the foreground region and the background region from the acquired image frames. There are various methods for separating the foreground region and the background region from the image frame. For example, there is a frame difference method in which two consecutive image frames are compared and a foreground region is searched from the difference. Alternatively, the color distribution of each pixel can be modeled as a single Gaussian function or multiple Gaussian functions. Also, there is a method of separating a pixel into a foreground region or a background region by expressing only the probability distribution without modeling the color distribution with a specific function. Generally, foreground / background separations use color, but edges or textures are used in addition to colors. One way to use a texture is to use a "local binary pattern" or a "mixture of dynamic textures". The object extracting unit 130 classifies the objects into the important region candidate group and the non-critical region candidate group by applying a support vector machine (SVM) learning unit from the separated foreground region, and extracts the object or object from the important region candidate group. The first object counting unit 140 generates the object counting information by counting the extracted object.

2B, the camera 100 includes a second image acquiring unit 150, a difference image acquiring unit 160, an object extracting unit 170, an object tracking unit 180, a second object counting unit 190, . The second image acquiring unit 150 acquires an image frame of a space in which the camera 100 is arranged using an image pickup device composed of a CCD sensor or a CMOS sensor. The difference image obtaining unit 160 calculates a difference image between the previous image frame and the previous image frame. The object extracting unit 170 extracts an object from the difference image. The SVM learning machine can be applied at the time of extracting the object, and the object having the similar size can be extracted by scanning the set reference object from the difference image. The object tracking unit 180 tracks the direction of the extracted object. The second object counting unit 190 counts a moving object to generate object count information.

Furthermore, the camera 100 sets a virtual line in the acquired spatial image, and when the extracted object passes through the virtual line, it can be counted as the number of objects to generate the object coefficient information. Hereinafter, the first camera 100_1 to the N-th camera 100_N will be described as a camera 100 for convenience of explanation.

Here, the first value is a case where the object does not pass through the infrared sensor, and the second value is the object when the object passes the infrared sensor.

When the sensor unit 200 is a pressure sensor, the sensor unit 200 is installed on the floor on which the object is walking, outputs a first value when the pressure sensing value is equal to or lower than the reference pressure, and outputs a second value when the pressure sensing value exceeds the reference pressure can do. Here, the first value is the case where the object is not pressed by the pressure sensor, and the second value is the object of counting when the object is pressed on the pressure sensor.

When the sensor unit 200 is a temperature sensor, when the reference temperature of the object is set to 36.5 degrees and a reference temperature exceeding or less than a certain range error is detected, the first value is output. When the reference temperature within a predetermined range error is detected And outputs a second value. Here, the first value is not an object but an object, and the second value is an object of an object if it is an object.
