Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, a schematic diagram of a video camera capturing device according to an embodiment is shown. The inventors provide a camera shooting dynamic capture object device, which comprises a camera 11, a capacitance sensor 12, a processing unit 13, a first angle sensor 14 and a second angle sensor 15; the processing unit 13 is electrically connected with the capacitive sensor 12, the first angle sensor 14 and the second angle sensor 15 respectively;
the processing unit 13 is configured to control the capacitive sensor 12 to rotate along a preset direction, and the capacitive sensor 12 is configured to detect whether a dielectric constant of a capacitor in an induction range of the capacitive sensor is within a first preset threshold range;
the processing unit 13 is a component capable of receiving signals, performing logic processing, and issuing control commands, such as: the processing unit 13 of the present invention is mainly used for receiving signals transmitted by each unit module (the capacitance sensor 12, the first angle sensor 14, the second angle sensor 15, etc.), and sending out control signals after processing, so as to control the normal operation of each unit module. The processing unit 13 is configured to control the capacitive sensor 12 to rotate along a preset direction, where the preset direction is a rotation direction that the capacitive sensor 12 is set by a user in advance through the processing unit 13; in general, the capacitive sensor 12 moves in a 360 ° rotational motion along its own plane.
The capacitance sensor 12 can judge whether a target enters the sensing range of the capacitance sensor through the capacitance dielectric constant change of the capacitance sensor, and further can judge which target enters through the numerical value of the capacitance dielectric constant; in a specific embodiment, for example, when a human body enters the sensing range of the capacitive sensor 12, the dielectric constant of the capacitor generally changes to 50-80 farads/meter, so that the device for dynamically capturing a target by shooting according to the present invention only needs to capture the human body, the first preset threshold range is set in the processing unit 13 to be 50-80 farads/meter, and when the capacitive sensor 12 detects that the dielectric constant of the capacitor is within 50-80 farads/meter, it indicates that the capacitive sensor 12 has found the human body; of course, according to different targets, different first preset threshold ranges are set so as to realize monitoring for the specific target; in a preferred scheme, in order to achieve a better positioning effect, shielding devices are arranged on two sides of the capacitive sensor 12, so that the sensing range of the capacitive sensor 12 is concentrated in a smaller area, the monitoring range of the capacitive sensor 12 after being shielded by the shielding devices is a sector area, and the central angle of the sector area is preferably not more than 10 degrees, and the position of a target can be accurately determined by adopting the structure; the optimal solution is to make the sensing range of the capacitive sensor 12 concentrated into one line, and then the target position determined by the capacitive sensor 12 is the most accurate.
The first angle sensor 14 is configured to record a first angle when the capacitive sensor 12 determines that the dielectric constant of the capacitor is within a preset threshold range, and the processing unit 13 controls the capacitive sensor 12 to stop rotating, where the first angle is an angle at which the current position of the capacitive sensor 12 rotates relative to the initial position of the capacitive sensor;
the processing unit 13 is further configured to determine a second angle, and control the camera 11 to rotate by the second angle, where the second angle is determined according to the angle correspondence between the initial positions of the camera 11 and the capacitive sensor 12 and the first angle; because the capacitive sensor 12 and the camera 11 may not be located in the same direction to a large extent before starting operation, for example, there is an included angle of 90 ° between the initial positions of the capacitive sensor 12 and the camera 11, when the capacitive sensor 12 moves 60 ° clockwise to find a target, the camera 11 needs to rotate 150 ° clockwise to capture a monitored target, and then the second angle needs to be determined according to the angle correspondence between the initial positions of the camera 11 and the capacitive sensor 12 and the first angle.
The second angle sensor 15 is configured to send a rotation stop signal to the processing unit 13 after detecting that the camera 11 rotates by a second angle, and the processing unit 13 is configured to receive the rotation stop signal and control the camera 11 to stop rotating. The angle sensor, as the name implies, is used to detect an angle. It has a hole in its body to fit the shaft of the musical instrument. When attached to the RCX, the angle sensor counts every 1/16 shaft revolutions. When the rotation is made in one direction, the count is increased, and when the rotation direction is changed, the count is decreased.
The camera 11 is configured to perform a first operation on a monitored target within a monitoring range after stopping rotation. Therefore, the function of quickly and dynamically capturing the target is realized.
The first operation comprises the steps of taking a picture or continuously monitoring a monitoring target; preferably, after the camera 11 finishes capturing the target, the camera 11 can be set to execute different operations through the processing unit 13 according to different specific monitoring areas used by the camera 11, for example, if the camera 11 is used in a hospital, the daily flow of people in the hospital is large, and the difficulty of using the camera 11 to continuously monitor different character targets is large, the camera 11 is set to execute a photographing function at this time, different character targets entering a monitoring range are photographed, and if the camera is used in a place where general people cannot enter, such as a vault, the camera 11 can be set to execute continuous monitoring at this time, and the whole-course behavior of the target character within the monitoring range is recorded; in addition, the camera 11 may be set by the processing unit 13 to perform different operations according to different time periods, for example, performing a photographing function when the flow of people is large in the daytime, and performing a continuous tracking function when the flow of people is small at night.
In a further embodiment, the device for capturing a target dynamically by camera shooting of the present invention further includes an infrared sensor 16, the infrared sensor 16 is connected to the processing unit 13, and the infrared sensor 16 is configured to start the capacitive sensor 12 and control the capacitive sensor 12 to rotate along a preset direction when detecting an infrared signal within a second preset threshold range. In the device of the invention, the infrared sensor 16 can play a role of remote early warning, when the human body is taken as a target to be monitored, the wavelength of infrared rays emitted by the human body is generally about 10um, and 9-11um is better when a second preset threshold range is set in the processing unit 13; in a specific embodiment, the filter is placed inside the infrared sensor 16 so that it only senses the infrared wavelengths emitted by a specific target. The distance sensed by the infrared sensor 16 is far away from the capacitance sensor 12, and when the infrared sensor 16 senses that the target is close to the capacitance sensor, the capacitance sensor 12 is started again to detect the dielectric constant of the capacitance, so that the effects of improving the efficiency of capturing the target by remote early warning and saving energy can be achieved.
In certain preferred embodiments, a first preset threshold range of capacitance dielectric constants, and a second preset threshold range of infrared wavelengths, set in the processing unit 13, should be set for the same target; such as: the first preset threshold range is a dielectric constant variation range of capacitance caused by the fact that a human body enters the sensing range of the capacitance sensor 12, and the length of the infrared light wavelength set in the corresponding second preset threshold range is also the wavelength of infrared rays emitted by the human body when needed. Therefore, the infrared sensor can only have due early warning effect, and when a human body enters, the capacitive sensor 12 is started to work.
In a further embodiment, the capacitance sensor 12 is further configured to send a shutdown signal to the processing unit 13 when determining that the dielectric constant of the capacitor is within the preset threshold range; the processing unit 13 is configured to receive a shutdown signal and shut down the capacitive sensor 12. When the capacitance sensor 12 determines that the dielectric constant of the capacitor is within the preset threshold range, it indicates that the capacitance sensor 12 has sensed the position of the target, and at this time, if no other target enters the sensing range of the capacitance sensor 12, the rotation of the capacitance sensor 12 can be stopped, so that the power consumption is reduced, and the service life of the sensor is prolonged.
As shown in fig. 3, an embodiment of the present invention relates to a schematic structural diagram of a device for capturing images of a dynamic capture object, and in a specific embodiment, the device further includes a capacitance rotation module 17, where the "processing unit 13 is configured to control the capacitance sensor 12 to rotate in a preset direction" specifically includes: the capacitance sensor 12 is disposed on the capacitance rotation module 17, and the processing unit 13 is configured to control the capacitance rotation module 17 to rotate so as to drive the capacitance sensor 12 to rotate along a preset direction. The capacitance rotation module 17 is used as a carrier for carrying the capacitance sensor 12, the capacitance rotation module 17 is electrically connected with the processing unit 13, the processing unit 13 sends out a start or stop signal of the capacitance rotation module 17, and the capacitance rotation module 17 starts or stops rotating, so as to drive the capacitance sensor 12 to start or stop rotating.
In a further embodiment, the apparatus further includes a pan-tilt module 18, where the "controlling the camera 11 to rotate by the second angle by the processing unit 13" specifically includes: the camera 11 is disposed on the pan/tilt head module 18, and the processing unit 13 is configured to control the pan/tilt head module 18 to rotate so as to drive the camera 11 to rotate by a second angle. The pan/tilt module 18 is used as a carrier for carrying the camera 11, the pan/tilt module 18 is electrically connected to the processing unit 13, the processing unit 13 sends a start or stop signal to the pan/tilt module 18, and the pan/tilt module 18 starts or stops rotating, so as to drive the camera 11 to start or stop rotating.
Please refer to fig. 2, which is a flowchart illustrating a method for capturing a target according to an embodiment of the present invention. The inventor also provides a method for shooting a dynamic capture target, which is applied to a device for shooting the dynamic capture target, wherein the device comprises a camera, a capacitance sensor, a processing unit, a first angle sensor and a second angle sensor; the processing unit is electrically connected with the capacitance sensor, the first angle sensor and the second angle sensor respectively; the method comprises the following steps:
step S102, a processing unit controls a capacitance sensor to rotate along a preset direction, and the capacitance sensor detects whether the dielectric constant of a capacitor in an induction range of the capacitance sensor is within a first preset threshold range;
the processing unit is a component capable of receiving signals, performing logic processing and issuing control commands, such as: the processing unit is mainly used for receiving signals transmitted by each unit module (a capacitance sensor, a first angle sensor, a second angle sensor and the like), and sending out control signals after processing so as to control the normal work of each unit module. The processing unit is used for controlling the capacitive sensor to rotate along a preset direction, and the preset direction is the rotating direction which is preset by a user through the processing unit; generally, the motion direction of the capacitive sensor is 360 ° of rotation along the plane of the capacitive sensor.
Step S103, when the capacitance sensor judges that the dielectric constant of the capacitor is within a preset threshold range, the first angle sensor records a first angle, wherein the first angle is an angle formed by rotating the current position of the capacitance sensor relative to the initial position of the capacitance sensor;
the capacitance sensor can judge whether a target enters the sensing range of the capacitance sensor through the capacitance dielectric constant change of the capacitance sensor, and further can judge which target enters through the numerical value of the capacitance dielectric constant; in a specific embodiment, for example, when a human body enters a sensing range of the capacitive sensor, the dielectric constant of the capacitor generally changes to 50-80 farads/meter, so that the shooting dynamic target capturing device only needs to capture the human body, a first preset threshold range is set in the processing unit to be 50-80 farads/meter, and when the capacitive sensor detects that the dielectric constant of the capacitor is within 50-80 farads/meter, the capacitive sensor indicates that the human body is found by the capacitive sensor; of course, according to different targets, different first preset threshold ranges are set so as to realize monitoring for the specific target; in the preferred scheme, in order to realize a better positioning effect, the shielding devices are arranged on two sides of the capacitive sensor, so that the sensing range of the capacitive sensor is concentrated in a smaller area, the monitoring range of the capacitive sensor after being shielded by the shielding devices is a sector area, and the central angle of the sector area is preferably not more than 10 degrees, and the position of a target can be accurately determined by adopting the structure; the optimal scheme is that the sensing range of the capacitive sensor can be concentrated into one line, and the target position determined by the capacitive sensor is the most accurate.
Step S104, the processing unit determines a second angle and controls the camera to rotate the second angle, wherein the second angle is determined according to the angle corresponding relation between the initial positions of the camera and the capacitive sensor and the first angle;
before the capacitive sensor and the camera start to work, the capacitive sensor and the camera may not be located in the same direction to a great extent, for example, an included angle of 90 degrees exists at an initial position between the capacitive sensor and the camera, so that when the capacitive sensor moves 60 degrees in the clockwise direction to find a target, the camera needs to rotate 150 degrees in the clockwise direction to capture a monitoring target, and then a second angle needs to be determined according to an angle corresponding relationship between the camera and the initial position of the capacitive sensor and the first angle.
Step S105, after the second angle sensor detects that the camera rotates by a second angle, the second angle sensor sends a rotation stopping signal to the processing unit, and the processing unit receives the rotation stopping signal and controls the camera to stop rotating;
and step S106, after the camera stops rotating, executing a first operation on the monitored target in the monitoring range.
In a further embodiment, before step S102, step S101 is performed, in which the processing unit first controls the infrared sensor to start, and when the infrared sensor detects an infrared signal within a second preset threshold range, the infrared sensor starts the capacitive sensor and controls the capacitive sensor to rotate along a preset direction. The infrared sensor in the device can play a role of remote early warning, when the human body is taken as a target to be monitored, the wavelength of infrared rays emitted by the human body is generally about 10um, and 9-11um is better when a second preset threshold range is set in the processing unit; in a specific embodiment, the filter is arranged inside the infrared sensor so that the filter only senses the infrared wavelength emitted by a specific target. The distance that infrared sensor responds is far away than capacitive sensor, and when infrared sensor senses that the target is close, the dielectric constant that restarts capacitive sensor carries out the electric capacity detects, can play long-range early warning and improve the efficiency of catching the target and energy-conserving effect.
In some embodiments, the capacitive sensor sends a shutdown signal to the processing unit when determining that the dielectric constant of the capacitor is within a preset threshold range; the processing unit receives a shutdown signal and shuts down the capacitive sensor. When the capacitance sensor judges that the dielectric constant of the capacitor is within the preset threshold range, the capacitance sensor indicates that the capacitance sensor senses the position of the target at the moment, and at the moment, if no other target enters the sensing range of the capacitance sensor, the rotation of the capacitance sensor can be stopped, the power consumption is reduced, and the service life of the sensor is prolonged.
