Abstract
An apparatus for sensing a dynamic object, comprising: camera, software system. The camera is an image frame acquisition device with laser transmitting and receiving functions or \ and infrared transmitting and receiving functions, and is connected with the software system through a wired or \ and wireless network (or a circuit). The software system is a system for receiving camera image frame data, storing, analyzing and sensing dynamic state. It is a feature of the present invention that it can or preferably operates to capture only a particular band of visible light at a particular wavelength. Another feature of the present invention is that it is possible to determine whether there is a very slow movement of the object by comparing to a previous frame. The invention has another characteristic that a plurality of cameras can be deployed and operated simultaneously so as to achieve the aim of multi-angle and all-directional security.
Description
Technical Field
The invention relates to the field of induction and monitoring, in particular to a method and a device for inducing a dynamic object.
Background
Conventional infrared (or laser) through detectors are easily disabled by a person using an infrared beam (or laser beam) transmitter to illuminate a receiver to disable the infrared (or laser) through detector (as performed in a movie). Conventional thermal imager detectors may not detect people that are all-around (i.e., as a movie is being played). The invention produces a device and a method for sensing action and/or picture change by a laser or/and infrared camera, can sense the change in the picture to at least a certain extent, avoids invalid falling by an infrared ray beam (or laser beam) emitter to at least a certain extent, avoids the condition that people wrapped around the whole body cannot be detected, and can sense the distance which can exceed 10 meters, even 30 meters or 50 meters. Another feature of the present invention is that it can be determined whether there is a very slow moving object in a frame compared to the previous frame, so as to make up for the potential safety hazard of most cameras to the very slow moving object. The invention has another characteristic that a plurality of cameras can be deployed and operated simultaneously so as to achieve the aim of multi-angle and all-directional security.
Disclosure of Invention
According to one aspect of the present disclosure, there is provided an apparatus for sensing a dynamic object, comprising: camera, software system.
The camera is an image frame acquisition device with laser transmitting and/or receiving functions or/and infrared transmitting and/or receiving functions, and is connected with the software system through a wired or/and wireless network (or circuit).
The software system is a system for receiving camera image frame data, storing, analyzing and sensing dynamic state.
According to one aspect of the present disclosure, there is provided a method of sensing a dynamic object, comprising:
the camera receives certain laser or/and infrared rays emitted by the camera, and sends image frames to the software system through a wired or/and wireless network (or circuit).
The software system compares the latest image frame received with the previous image frame information to determine if there has been a change.
Preferably, as an alternative embodiment, the camera may only receive a certain laser or/and infrared ray (laser or/and light or/and infrared ray in a certain wavelength region) to form image frame information.
Preferably, as an alternative embodiment, the camera may add a filter to receive only certain laser or/and infrared rays (laser or/and light or/and infrared rays in a certain wavelength region) to form image frame information.
Preferably, as an alternative embodiment, a filter of a certain wavelength or a certain stage of wavelength (e.g. 16nm or 37nm or 67nm wavelength) may be added to the camera to make the camera complete or nearly complete to receive only light of a certain wavelength.
Preferably, as an alternative embodiment, the camera may be a more common camera with infrared emission function.
Preferably, the camera has laser or/and infrared rays (laser or/and light or/and infrared rays in a certain wavelength region) emitted by the camera, which include light with a wavelength that can be filtered by the filter, so as to ensure that a content image can be generated.
Preferably, the image frames are stored to a local storage device.
Further, as an alternative implementation, the storage may be in a memory (short-term non-persistent storage) or in a hard disk or a flash memory (long-term persistent storage).
Preferably, the current image frame information is compared with the image frame information of the previous frame, and a change is considered to occur when the change rate exceeds a certain threshold value.
Preferably, the comparison with the image frame information of the maximum number of frames before is determined according to the information configured in advance, and the change is considered to occur when the change rate exceeds a certain threshold value (for example, the comparison with the previous tenth frame image).
Detailed Description
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Example 1
Step 1: the camera is provided with an infrared ray or laser emitter for emitting infrared rays or lasers, and acquires image frame information with the wavelength of 37nm through a filter and transmits the image frame information to the software system.
Step 2: comparing the current image frame information with the image frame information of the previous frame, and when the image difference meets the condition that the image difference exceeds the threshold value (for example, 3 thousandths) read in the configuration file, the picture is considered to be changed.
And step 3: the current image frame information is compared with the image frame information of the previous 10 th frame, and when the image difference meets and exceeds a threshold value (for example, 3 thousandths) read in the configuration file, the picture is considered to be changed.
Further, the 10 th frame before the comparison here is configured in the configuration file.
And 4, step 4: the software system considers that the picture has changed when it finds that the change in the image frame exceeds a threshold read in the configuration file (e.g. 3 thousandths), and may give a prompt to sound.
The above is a specific embodiment of the present invention, but the scope of the present invention should not be limited thereto. Any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the appended claims.
