Detailed Description
Fig. 1 is a schematic diagram of a captured information analysis system of the present invention, fig. 2 is a schematic diagram of captured information of a single image capturing unit of the present invention, and fig. 3 is an analysis schematic diagram of the captured information analysis system of the present invention. Referring to fig. 1 to 3 together, the captured information analysis system 100 includes a host unit 110 and a plurality of image capturing units 120, and for convenience, the captured information analysis system 100 is illustrated as having four image capturing units 120a-120d in fig. 3.
The host unit 110 prestores a first map M, which is map data of a first area, preferably, the first map M is a three-dimensional map, that is, objects of the first map M are in a three-dimensional state, and all the objects on the map have height data, and the captured information analysis system 100 analyzes a plurality of captured information (each image capture unit 120 has one captured information) captured by a plurality of image capture units 120 in the first area.
As shown in fig. 2, the capturing information of each image capturing unit 120 includes corresponding position information (shown by a box), direction vector information (shown by an arrow) and view angle information (shown by a cone), where the position information is a three-dimensional coordinate of the image capturing unit 120 capturing the current image, the direction vector information is a direction of the image capturing unit 120 capturing the current image, and the view angle information is a view angle range of the image capturing unit 120 capturing the current image. The capturing information of the image capturing unit 120 capturing the current image can be defined by the position information, the direction vector information and the view angle information, and the attention area (shown by the dashed line frame) of each capturing information can be defined, and then the host unit 110 can preliminarily determine the current capturing area of the image capturing unit 120 by combining the first map M, i.e. analyze and calculate the attention area of the image capturing unit 120.
The host unit 110 and the image capturing units 120 have data connections (as shown by dotted lines in fig. 1), and the image capturing units 120 can transmit corresponding capturing information to the host unit 110 through the data connections. The image capturing unit 120 may be a mobile phone, a camera, or smart glasses, or other mobile electronic devices with image capturing and data transmission functions. In the embodiment, the host unit 110 is integrated into one image capturing unit 120, and of course, in other embodiments, the host unit 110 may be independent from a plurality of image capturing units 120, for example, the host unit 110 may also be a communication server whose communication range covers the first area.
After receiving the captured information, the host unit 110 analyzes the captured information and the first map M to obtain an overlapping area E (shown by a black filled box), and the analyzing process of the overlapping area E is as follows: first, the host unit 110 sequentially analyzes the areas captured by the image capturing units 120 according to the capturing information and the first map M, i.e., obtains the attention areas (shown by the dashed line frames) corresponding to the image capturing units 120, and then the host unit 110 determines whether there is an overlapping area E according to the attention areas. In the determining process, it is necessary to consider the height data of the first area, as shown in fig. 3, the first area has the first object M1, if two image capturing units (e.g., 120a and 120d) of the plurality of image capturing units 120 are respectively located at two opposite sides of the first object M1, the host unit 110 determines that the regions of interest of the captured information corresponding to the two image capturing units (e.g., 120a and 120d) do not overlap, and the image capturing units 120b, 120c, and 120d do not have the obstruction in the height of the three-dimensional object, and in combination with the data of the first map M, the host unit 110 can determine that the regions of interest of the captured information corresponding to the image capturing units 120b, 120c, and 120d have the overlap region E.
After determining whether there is the overlap area E, the host unit 110 cannot immediately determine that there is a hot event in the overlap area E, and the host unit 110 also needs to determine the overlap amount of the overlap area E, and analyze the number of the image capturing units capturing the overlap area E in a certain time period (for example, the number of people capturing the overlap area E in a certain time period) to determine whether there is a hot event in the overlap area E. That is, if it is determined that the number of the overlapping areas E in the attention area corresponding to the capturing information is greater than the predetermined number, that is, if the image capturing units 120 having the number greater than the predetermined number are in the attention overlapping area E, the host unit 110 outputs the overlapping area E.
In other words, if the extracted information analysis system 100 determines that there are multiple people in the extracted overlapping area E, that is, it is estimated that there is a hot event in the overlapping area E, the information including the position of the overlapping area E is quickly transmitted to the user near the position of the overlapping area E in real time to inform the user of the possible hot event, or transmitted to the government information management department for the government information management department to refer to whether necessary measures need to be taken.
In addition, the preset number represents the attention degree of defining the hot spot event, so the setting of the preset number is set by self according to the actual situation. As shown in fig. 3, the predetermined number may be three or more. If the preset number is three, the host unit 110 determines that the event occurring in the overlapping area E is a hot event and outputs the overlapping area E in which the hot event occurs, but if the preset number is three or less, the host unit 110 determines that the event occurring in the overlapping area E is not a hot event and does not output the overlapping area E.
In this embodiment, to implement the analysis, storage and communication capabilities of the host unit 110, the host unit 110 includes a processing unit 111, a storage unit 112 electrically connected to the processing unit 111, and a first communication unit 113 electrically connected to the processing unit 111, the first map M is stored in the storage unit 112, the processing unit 111 analyzes and calculates the overlapping area E according to the plurality of capturing information and the first map M, and the first communication unit 113 is used for implementing the data connection with the plurality of image capturing units 120.
Accordingly, in order to obtain the corresponding capturing information and ensure the effective communication capability, as shown in fig. 1, each of the plurality of image capturing units 120 includes a positioning unit 121, a direction detecting unit 122 and a second communication unit 123. Generally, the viewing angle range of the image capturing unit 120 is usually a fixed value, so that each image capturing unit 120 can pre-store the corresponding viewing angle information, and two other pieces of information, position information and direction vector information, of the captured information can be obtained by performing detection. The positioning unit 121 includes a global satellite positioning unit (not shown) for detecting the X coordinate and the Y coordinate of the image capturing unit 120 in the world coordinate system, and an air pressure detecting unit (not shown) for detecting the Z coordinate of the image capturing unit 120 in the world coordinate system in cooperation with the global satellite positioning unit. The direction detecting unit 122 includes an electronic compass and a gyroscope, and is used for detecting direction vector information when the image capturing unit 120 captures the image. Regarding the communication capability, the second communication unit 123 of the image capturing unit 120 is used for data connection with the first communication unit 113 of the host unit 110, and for convenience, the data connection is usually a wireless data connection.
In summary, if the captured information analysis system of the present invention determines that there are multiple people capturing the overlapping area, that is, it is estimated that there is a hot event occurring in the overlapping area, the captured information analysis system will quickly transmit the information including the position of the overlapping area to the user near the position of the overlapping area in real time, so as to inform the user of the possible hot event, or transmit the information to the government information management department, so as to allow the government information management department to refer to whether necessary measures need to be taken.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
