Of course, the application scenario of the focus control method according to the embodiment of the present invention is not limited thereto. For convenience of description, the following description is given by taking the application in a substation scene as an example, that is, the first electronic device is an inspection device applied in the substation scene, and the second electronic device is a temperature measurement device applied in the substation scene, but the description is not limited thereto.

A first aspect of an embodiment of the present invention provides a focus control method, which is applied to an electronic system, where the electronic system includes: a first electronic device and a second electronic device. Referring to fig. 1, in one embodiment, a focus control method includes the steps of:

s100: when the first electronic equipment patrols and examines a target preset point, acquiring target preset point information corresponding to the target preset point; the target preset point information at least comprises a first focusing parameter, and the first focusing parameter is applied to the second electronic equipment;

s200: and the first electronic equipment sends the first focusing parameter to the second electronic equipment, so that the second electronic equipment adjusts the current focusing parameter to be matched with the first focusing parameter.

An execution subject of the focus control method of the first aspect of the embodiment of the present invention is the first electronic device. The second electronic device may be mounted on the first electronic device so as to be movable with the first electronic device. For example, the second electronic device may be assembled to the first electronic device through the cradle head, and the first electronic device may drive the cradle head to drive the second electronic device to rotate, so that the second electronic device may face the target direction. Of course, the second electronic device may be assembled to the first electronic device in other manners. The second electronic device and the first electronic device can be connected through a network interface to realize data communication.

First electronic equipment can be ground robot, or unmanned aerial vehicle etc. and first electronic equipment can take second electronic equipment to patrol and examine in patrolling and examining the region to investigate out the electrical equipment of temperature anomaly.

The second electronic device may be a thermal imager, and may include a thermal imaging lens, a thermal imaging engine, and the like. The thermal imaging engine may have an image sensor or the like that is sensitive to thermal infrared. The infrared light passes through the thermal imaging lens and is imaged on the image sensor, and an imaging picture can reflect the temperature field on the surface of the object.

Specifically, referring to fig. 2, the first electronic device 500 is connected to the second electronic device 400, preferably, through a communication interface such as UART (asynchronous receiver transmitter). Second electronic device 400 may include a thermal imager core 401 and a lens 402.

The lens may contain a motor 4021, a focusing assembly 4022, and the like, and the focusing assembly 4022 may include a lens, a potentiometer, and the like. The motor 4021 can drive the focusing assembly 4022 to realize focusing of the focusing assembly 4022, and meanwhile, the motor 4021 can drive the potentiometer, and the resistance value of the potentiometer can reflect the position of the motor.

Thermal imager core 401 may include processor 4011, motor driver chip 4012, and the like. The processor 4011 can acquire signals on the potentiometer in the focusing assembly 4022 through the voltage division circuit and the sampling circuit to obtain focusing parameters. The processor 4011 may further receive an instruction of the first electronic device 500, and when receiving a control instruction, may output a PWM signal to the motor driver chip 4012. The motor driver chip 4012 can drive the motor 4021 in the lens 402 to move under the driving of the PWM signal of the processor 4011. The processor 4011 in the thermal imaging engine core 401 may be an FPGA, and the FPGA may be an FPGA with an NIOS II soft core, which is not limited specifically.

Of course, the illustration in FIG. 2 is for example only and not intended to be limiting.

In the step S100, when a first electronic device patrols and examines a target preset point, acquiring target preset point information corresponding to the target preset point; the target preset point information at least comprises a first focusing parameter, and the first focusing parameter is applied to the second electronic device.

The target preset point is any preset point needing to be set in the inspection area. The preset points can be set by manually picking points in the scene, and each preset point corresponds to one region position in the inspection region. In a substation inspection scene, a preset point can be set according to the position of a target object needing temperature measurement of a substation facility (including substation equipment, lines and the like); in other scenes, a preset point can be set for the position of the target object. The number of preset points in a scene is not limited, and may be, for example, 3, 20, 100, 3000 preset points.

After the preset point setting is completed, corresponding preset point information can be set in the first electronic device or other devices. The first electronic equipment can patrol and examine according to the route of patrolling and examining that predetermines, patrol and examine in proper order to each preset point that needs set up in patrolling and examining the region. Of course, the routing inspection path is not limited.

When the first electronic equipment patrols and examines the target preset point, the first electronic equipment can acquire target preset point information corresponding to the target preset point from the equipment or other equipment. The target preset point information at least comprises a first focusing parameter, and the first focusing parameter is applied to the second electronic equipment, so that the focusing of the second electronic equipment can be realized. Of course, the target preset point information may also include other information, such as a preset point, a location of an area corresponding to the preset point, and the like, which is not limited in detail.

In step S200, the first electronic device sends the first focusing parameter to the second electronic device, so that the second electronic device adjusts the current focusing parameter to match the first focusing parameter.

The first electronic device may send the first focus parameters to the second electronic device through a network interface of the first electronic device with the second electronic device. The second electronic device receives the first focus parameter transmitted from the first electronic device. Of course, there may be other information sent with the first focusing parameter, such as the temperature when the target preset point information is set, and the details are not limited.

The first focusing parameter may be carried by the first electronic device in a control instruction to the second electronic device. When the second electronic device receives the control instruction, the first focusing parameter can be analyzed from the control instruction, and the current focusing parameter of the device is adjusted according to the first focusing parameter according to the instruction of the control instruction.

Since the first focus parameter is set when the preset point is set, it is a focus parameter of the second electronic device when focusing on the target object. The first focusing parameter can indicate a target position where the motor is located when the lens on the second electronic device focuses on the target object, and the second electronic device is controlled to focus according to the first focusing parameter, so that the motor in the lens on the second electronic device can be rapidly moved to the target position when the lens focuses on the target object, and rapid focusing is achieved.

For example, when a target preset point at which the first electronic device is currently located is set, and the second electronic device is focused on a certain target object, the second electronic device adjusts the current focusing parameter to match the first focusing parameter, so that the second electronic device can be quickly restored to a state of focusing on the target object.

How the second electronic device adjusts the current focusing parameter to match the first focusing parameter, for example, when the first focusing parameter is an unnormalized focusing parameter (a focusing parameter directly read from the second electronic device when a preset point is set), the second electronic device may adjust the current focusing parameter of the second electronic device to the first focusing parameter; or, when the first focusing parameter is a normalized focusing parameter (when a preset point is set, the focusing parameter after normalization processing of the focusing parameter read from the second electronic device), the second electronic device may perform inverse normalization processing on the first focusing parameter, and then adjust the current focusing parameter of the device to the focusing parameter after inverse normalization processing. The above-described modes are only examples and are not intended to be limiting.

In addition, a foreground and background phenomenon exists in a common scene, the automatic focusing by adopting a climbing algorithm in a related focusing mode may focus on the foreground or the background, and if a target object is the foreground and actually focuses on the background, the foreground is blurred, and a focusing error occurs; in addition, in low temperature difference weather, the sharpness evaluation value cannot reflect the sharpness of the picture accurately, for example, the evaluation value of the cleanness of a blurred picture is the highest, which results in failure of focusing.

In the embodiment of the invention, the second electronic device can be directly adjusted to be in a state of focusing on the target object according to the first focusing parameter, so that the problems of wrong focusing on the target object due to the foreground and background phenomena and failure in focusing due to low-temperature difference weather are avoided.

In one embodiment, the above method flow can be executed by a focus control apparatus, as shown in fig. 3, the focus control apparatus 100 can include 2 modules: a target preset point information acquisition module 101 and a first focusing parameter sending module 102. The target preset point information obtaining module 101 is configured to perform the step S100, and the first focusing parameter sending module 102 is configured to perform the step S200.

In one embodiment, in step S100, the acquiring, by the first electronic device, target preset point information corresponding to the target preset point includes:

s101: searching preset point information containing a target preset point identifier in all the set preset point information;

s102: and determining the searched preset point information as the target preset point information.

The preset points or preset positions can play a role in connecting the positions of the plurality of areas in the routing inspection area with the operation condition of the first electronic equipment. For example, a command for setting a preset point is sent to the first electronic device for each area position in the inspection area, and the first electronic device can record the current state, such as the position, the posture, the state of the pan/tilt head, and the like, and associate the current state with the preset point identifier; the subsequent first electronic equipment can run to the memory state of the preset point at the fastest speed so as to quickly patrol to each region position.

The first electronic device is provided with preset point information corresponding to all preset points, wherein each preset point information comprises a corresponding preset point identifier, a focusing parameter and the like. Of course, the preset point information may also include state information of the first electronic device when the corresponding preset point is set, and the like.

The focus parameters in the preset point information are: and when the corresponding preset point is set, the focusing parameters of the lens on the second electronic equipment are focused on the target object. The second electronic device can quickly recover to the state when the corresponding preset point is set according to the focusing parameter in the preset point information, namely, the state of focusing on the target object.

The preset point identification may uniquely represent the corresponding preset point. When the first electronic equipment patrols and examines the target preset point, the target preset point identification can be determined, and the target preset point information can be searched according to the target preset point identification. Searching preset point information containing target preset point identification in all the set preset point information, and determining the searched preset point information as target preset point information. The focusing parameter in the target preset point information is the first focusing parameter.

In one embodiment, the first electronic device sets all the preset point information by:

The first electronic equipment can set a plurality of preset points for the inspection area of the equipment, and the preset points correspond to different positions in the inspection area.

In the preset point setting process, when the first electronic device is located at each preset point to be set in the inspection area, under the condition that the second electronic device is determined to be focused on the target object, the second focusing parameter of the second electronic device can be obtained, and the preset point information corresponding to the preset point is obtained according to the obtained second focusing parameter.

The image definition of the second electronic device can be manually adjusted, or the image definition of the second electronic device can be automatically adjusted under the condition of good weather (non-low temperature difference weather such as non-rain and fog weather), so that the second electronic device can be ensured to focus on the target object.

When the target object is focused on the second electronic equipment, the definition of the target object in the picture imaged by the second electronic equipment reaches the preset definition. The preset point information when the first electronic equipment is at a certain preset point comprises a second focusing parameter when the second electronic equipment focuses on the target object; subsequently, when the first electronic device is at the preset point, the second electronic device can control the device to focus on the target object according to the second focusing parameter in the information of the preset point corresponding to the preset point.

When the preset point is set, the second electronic device can calculate the definition evaluation value of the picture according to a preset definition evaluation algorithm, and the FPGA soft core can determine whether the target object is focused according to the definition evaluation value so that the second electronic device can complete focusing.

The first electronic device may acquire the second focusing parameter from the second electronic device by an active acquisition mode: the method comprises the steps that a first electronic device actively sends a control instruction; and the second electronic equipment determines the second focusing parameter of the equipment after receiving the control instruction and sends the second focusing parameter to the second electronic equipment. Alternatively, the determined second focusing parameter may be actively uploaded to the first electronic device by the second electronic device. Or, the second electronic device may also prompt the second focusing parameter, and the second focusing parameter is manually set to the first electronic device, which is not limited in specific manner.

The second electronic device may determine the second focusing parameter in the following ways:

the first method is that the second electronic device reads focusing parameters from a lens of the device and directly determines the read focusing parameters as second focusing parameters;

and secondly, the second electronic device reads out the focusing parameters from the lens of the device and inputs the read focusing parameters into a preset normalization mapping formula to obtain second focusing parameters.

For the first mode, since the preset point information includes the directly read focusing parameter, in step S200, after the first electronic device sends the first focusing parameter to the second electronic device, the second electronic device may directly adjust the current focusing parameter of the lens on the device to the first focusing parameter.

For the second mode, since the preset point information includes the normalized focusing parameter, in step S200, after the first electronic device sends the first focusing parameter to the second electronic device, the second electronic device needs to perform inverse normalization on the first focusing parameter, that is, the first focusing parameter is input into a preset inverse normalization mapping formula, and the current focusing parameter of the lens on the device is adjusted to the focusing parameter after the inverse normalization.

In order to avoid resetting the preset point information in the first electronic device when the first electronic device is replaced with a second electronic device of a different type, the embodiment of the present invention preferably adopts a second manner, which is described below.

Second electronic device in addition to the components shown in fig. 2, the thermal imaging cartridge may also include components (not shown in the figure) such as a voltage divider circuit, an AD sampling chip, and the like. With reference to fig. 2, when the motor 4021 in the lens 402 moves, the slide plate of the potentiometer is driven to move to change the resistance value of the potentiometer (the difference in resistance value indicates the position of the motor is different), the resistance value is converted into a voltage signal through the voltage dividing circuit, and the AD sampling chip performs AD sampling on the voltage signal obtained by the voltage dividing circuit to obtain an AD value. The processor 4011 can obtain the AD value obtained by sampling from the AD sampling chip through the I2C interface, and the AD value is used as the focusing parameter read by the second electronic device from the lens of the device.

When a certain preset point is set, if the second electronic device finishes focusing, the motor is located at a certain position A1, the FPGA soft core can collect the focusing parameters from the AD sampling chip at the moment, and the motor can directly move to the position A when the motor is controlled to move according to the focusing parameters subsequently, so that focusing is finished quickly.

The preset normalization mapping formula and the preset inverse normalization mapping formula may be determined according to an actual adjustable focusing parameter range (determined by an actual movable stroke of the motor) of the lens on the second electronic device and a set normalization focusing parameter range.

The minimum actual focusing parameter and the maximum actual focusing parameter in the actual adjustable actual focusing parameter range of the lens on the second electronic device may be calibrated at the time of factory shipment. During calibration, the second electronic device records the actual focus parameters at the closest object distance (e.g., 2M) and the farthest object distance (e.g., 20M). The focus parameter read from the lens at the closest object distance is taken as the maximum actual focus parameter, and the focus parameter read from the lens at the farthest object distance is taken as the minimum actual focus parameter. The specific value of the object distance is only an example for convenience of description, and the specific value is determined according to the lens.

A calibration tool may be used to calibrate the actual focus parameter range. The calibration tool is PC-side client tool software which is adopted when the calibration tool is used for calibrating the second electronic equipment at the nearest object distance and the farthest object distance by combining a focusing calibration process during production. The calibration tool is used for sending a calibration command to the second electronic device, when the second electronic device receives the calibration command, the calibration command is issued to the FPGA soft core, and the FPGA soft core reads the focusing parameters from the lens, so that the minimum actual focusing parameter and the maximum actual focusing parameter are obtained.

Optionally, if the environmental temperature is T0 during the calibration process, if the environmental temperature changes during the use of the device, the calibrated focusing parameters may be expanded as needed to make the calibrated focusing stroke meet the requirement of the working temperature of the device, and the actual focusing parameter range is determined according to the expanded focusing parameters.

And setting the minimum normalized focusing parameter in the normalized focusing parameter range to correspond to the nearest object distance, and setting the maximum normalized focusing parameter to correspond to the farthest object distance. The minimum normalized focus parameter and the maximum normalized focus parameter may be customized.

The minimum actual focusing parameter, the maximum actual focusing parameter, the minimum normalized focusing parameter and the maximum normalized focusing parameter can be written into a flash of the FPGA soft core, and the values can be read from the flash after the second electronic device is powered on again, so that the actual focusing parameter range is determined and the normalized focusing parameter range is set.

The normalized mapping formula may be used to map any one of the actual focusing parameters F1 in the actual focusing parameter range to one of the normalized focusing parameters F2 in the set normalized focusing parameter range, where the actual focusing parameter F1 and the normalized focusing parameter F2 have a certain mapping relationship M1.

The inverse normalized mapping formula may be used to map any one normalized focus parameter F3 in the set normalized focus parameter range to one actual focus parameter F4 in the actual focus parameter range, there is a certain mapping relationship M2 between the normalized focus parameter F3 and the actual focus parameter F4, and the mapping relationship M2 is reciprocal to the mapping relationship M1.

Specifically, the normalized mapping formula may be the following formula (1):

standard_pos＝S1*(ad_pos-min)/(max-min)+S2 (1)。

the denormalized mapping formula may be as follows (2):

ad_pos＝(max-min)*standard_pos/4000+min (2)。

wherein min is a minimum actual focusing parameter, max is a maximum actual focusing parameter, S1 is a maximum normalized focusing parameter, S2 is a minimum normalized focusing parameter, ad _ pos is an actual focusing parameter of the lens, and standard _ pos is a normalized focusing parameter. The range of the normalized focusing parameters may be, for example, 0 to 4000, i.e., 4000 for S1 and 0 for S2, which is only exemplary and not limiting.

It is understood that the minimum actual focus parameter and the maximum actual focus parameter of different second electronic devices may be different, so the values of the parameters max and min in the two formulas (1) and (2) may be different according to the second electronic devices.

The process of the first electronic device setting the preset point information is described below with reference to the above formula (1).

When the first electronic device is located at each preset point to be set in the inspection area, a control instruction can be sent to the second electronic device according to a prompt about focusing on a target object on the second electronic device, which is input from the outside.

After receiving the control instruction, the second electronic device confirms that the target object is focused on the device, reads a fourth focusing parameter from a lens on the device, inputs the fourth focusing parameter into formula (1) as a value of ad _ pos, calculates a value of standard _ pos as a second focusing parameter, and sends the second focusing parameter to the first electronic device, namely the second focusing parameter is the normalized focusing parameter.

And after receiving the second focusing parameter, the first electronic equipment obtains the preset point information corresponding to the preset point according to the second focusing parameter.

In the above process, the second electronic device may map all the read actual focus parameters to normalized focus parameters in the set normalized focus parameter range in a unified manner. The preset point information set by the first electronic equipment is normalized focusing parameters.

Therefore, multiplexing of each preset point information can be realized for different second electronic devices, and even if the second electronic device is replaced on the first electronic device or a lens is replaced on the second electronic device, the preset point information corresponding to all the preset points does not need to be collected again and recorded again.

The process of the second electronic device adjusting the current focusing parameter to match the first focusing parameter is described below with reference to the above formula (2).

The second electronic equipment receives a first focusing parameter sent by the first electronic equipment, wherein the first focusing parameter is a normalized focusing parameter, the first focusing parameter is used as a value of standard _ pos and is input into a formula (2), the value of ad _ pos is calculated to be used as a third focusing parameter, and the current focusing parameter of a lens on the equipment is adjusted to the third focusing parameter.

After the current focusing parameter of the lens on the second electronic device is adjusted to the third focusing parameter, the motor in the lens moves to the position represented by the third focusing parameter, and the position is the position of the motor when the lens on the second electronic device focuses on the target object when the preset point information where the first focusing parameter is located is set, so that focusing is realized.

Therefore, the motor can be controlled to directly move to the target position when the lens focuses on the target object, the motor does not need to be controlled to pull the focusing assembly back and forth to find out the target position, and the time required by the whole focusing process is shortened.

The benefits of setting the normalized focus parameters in the first electronic device are described below in a more specific example.

Assume that the maximum normalized focus parameter S1 is 4000 and the minimum normalized focus parameter S2 is 0.

When the first electronic device sets all the preset point information, the first electronic device is equipped with the second electronic device E1, and the setting of the preset point information is completed by the second electronic device E1. Suppose that:

the minimum actual focusing parameter min of the second electronic device E1 is 100;

the maximum actual focusing parameter max of the second electronic device E1 is 1000;

when the first electronic device is at the first preset point, the actual focusing parameter when the lens on the second electronic device E1 focuses on the target object is 300, and the object distance of the lens in the second electronic device E1 is assumed to be O1.

These parameter values are substituted into the above equation (1) to calculate the normalized focus parameter:

standard_pos＝S1*(ad_pos-min)/(max-min)+S2

＝4000*(300-100)/(1000-100)+0＝888。

the second electronic device E1 sends the normalized focusing parameter 888 as the second focusing parameter to the first electronic device, and the first electronic device sets 888 as the focusing parameter in the preset point information corresponding to the first preset point.

Subsequently, the second electronic device E1 on the first electronic device is replaced with a second electronic device E2 (in this embodiment, E1 and E2 are used to distinguish different second electronic devices), assuming that:

the minimum actual focusing parameter min of the second electronic device E2 is 200;

the maximum actual focus parameter max of the second electronic device E2 is 1200.

When the first electronic device patrols and examines to the first preset point, the focusing parameter standard _ pos in the preset point information corresponding to the first preset point, which is locally acquired by the first electronic device, is 888.

Substituting these parameter values into equation (2), the actual focus parameters required for the second electronic device E2 motor motion are calculated:

ad_pos＝(max-min)*standard_pos/4000+min

＝(1200-200)*888/4000+200＝422；

the second electronic device E2 motor moves to the position indicated by the actual focus parameter 422 to achieve focus and no longer to the position indicated by 300. At this time, the object distance of the lens in the second electronic device E2 is still O1, and the object distances of the second electronic device E1 and the second electronic device E2 are the same even though the actual focus parameters are different (300 and 422, respectively).

Of course, if the multiplexing of the preset point information among different devices is not considered, when the preset point of the first electronic device is set, the actual focusing parameter when the second electronic device focuses on the target object may also be directly set as the focusing parameter in the preset point information. Accordingly, the second electronic device does not need to perform normalization processing or inverse normalization processing.

Optionally, the model of the second electronic device is a target model, differences between actual focusing parameters of lenses of all second electronic devices in the target model at the same object distance are within a set error range, and the set error range is determined according to the actual focusing parameter range of the second electronic device in the designated model.

The manner of determining the target model may include:

providing a plurality of second electronic devices of a certain model, for example, 5, and respectively acquiring focusing parameters of lenses on different second electronic devices when the lenses are focused on a target object at an object distance of 1-12 m (the acquisition interval is 0.5 m); and the collected focusing parameters are analyzed and judged as follows:

and under the same object distance, whether the difference between the maximum value and the minimum value in all focusing parameters of the lens on different second electronic equipment is within a set error range or not, if so, determining that the lens meets the consistency requirement, and taking the model as a target model.

The set error range may be, for example, less than or equal to 3% of the total range, where 3% is only an example, and the actual visual field may be determined according to the actual lens adjustment, and is not limited.

In one embodiment, the target preset point information further includes: a first temperature; the first temperature is a temperature at which the first focusing parameter is set;

Because the lens in the lens on the second electronic device is made of germanium material, the lens is easy to deform along with the change of the ambient temperature, even if the lens is clearly focused at the first temperature, when the ambient temperature is changed to a preset temperature threshold value, the temperature threshold value is determined according to the actual lens, the virtual focus phenomenon is easy to occur, and the original focusing parameters can not enable the picture to be clearly focused under the condition.

In order to solve the above problem, when the first electronic device sends the first focusing parameter to the second electronic device, the first electronic device also sends the first temperature when the first focusing parameter is set to the second electronic device. The second electronic device can compensate the received first focusing parameter according to the first temperature, and adjust the current focusing parameter on the lens according to the compensated focusing parameter, so that the problem of virtual focus caused by focus offset due to temperature change can be solved.

The first temperature may be an ambient temperature at which the first focusing parameter is set. Of course, if it is not convenient to obtain the ambient temperature when setting, the cavity temperature of the second electronic device, the temperature of the lens on the second electronic device, or the like may be used instead.

Optionally, the first temperature and the first focusing parameter may be carried in a control command and sent by the first electronic device to the second electronic device. After receiving the control command, the second electronic device may analyze the first temperature and the first focusing parameter from the control command.

The control instructions may include a focus parameter field, a temperature flag bit, a temperature field, a sign flag bit, and the like. The focusing parameter field is used for recording a first focusing parameter, the temperature mark bit is used for identifying whether the control instruction carries a first temperature, the temperature field is used for recording an absolute value of the first temperature, and the sign mark bit is used for recording a sign of the first temperature.

Specifically, the control instruction may be 32 bits. Wherein, the 1 st to 15 th bits can be used as a focusing parameter field; the 16 th bit can be used as a temperature flag bit, for example, if the data on the 16 th bit is 0, it indicates that the first temperature is not carried, and if the data on the 16 th bit is 1, it indicates that the first temperature is carried; bits 17-30 can be used as a temperature field; the 31 st bit can be used as a sign flag bit, for example, if the data on the 31 st bit is 0, it indicates that the first temperature is a positive value, and if the data on the 31 st bit is 1, it indicates that the first temperature is a negative value; the 32 th bit may be set to 0, and in order to avoid the situation that the data in the control instruction is considered to be a negative number when the highest bit is 1 during the data transfer, the highest bit is discarded, that is, the 32 th bit is set to 0.

After the second electronic device parses the first temperature and the first focusing parameter from the control command, the following steps may be performed:

inputting the first focusing parameter into a preset inverse normalization formula, such as the formula (2), to obtain a third focusing parameter;

The fifth focusing parameter is a focusing parameter at the current temperature, and is a focusing parameter obtained by compensating the third focusing parameter according to the temperature difference between the first temperature and the current temperature, so that the current focusing parameter of the device is adjusted to the fifth focusing parameter, and the problem of virtual focus caused by focus offset due to temperature change can be solved.

Generally, when the object distance of the lens is constant and the ambient temperature is changed, the temperature change and the change of a focusing component such as a potentiometer are in a linear relation. Assuming that the temperature variation between the current temperature and the first temperature is Δ T ℃, the variation of the potentiometer resistance value is k × Δ T, where (k ═ k1+ k2) ohms, i.e., Δ R ═ k1+ k2 × Δ T (3), k1 is the temperature drift coefficient of the lens, and k2 is the temperature drift coefficient of the potentiometer.

Accordingly, a compensation method based on the focus compensation algorithm will be described below by taking the second electronic device as an example of a gun camera with a focal length of 25 mm.

Before compensation, the conversion relation between the resistance value of the potentiometer and the AD value on the AD sampling chip is determined in advance.

When the temperature changes, the resistance value after the temperature changes can be calculated, and then the resistance value is converted into the AD value of the AD sampling chip to be output (of course, the temperature change amount and the AD value are not in a linear relationship, and the resistance change amount of the potentiometer is in a linear relationship). The conversion relation between the resistance value of the potentiometer and the AD value on the AD sampling chip is as follows:

suppose that: the total resistance value of a potentiometer in the lens is 10k omega, and 3.3V is used for supplying power; the full range of the 16-bit AD sampling chip is 2.048V;

the formula for converting the resistance R1 of the potentiometer to an AD value is as follows:

conversely, the formula for converting the AD value to the potentiometer resistance R1 is as follows:

the AD is an AD value sampled by an AD sampling chip; r1 is the resistance of the lens potentiometer.

On the basis of the conversion relationship, the focus parameter is compensated.

Suppose that: the first temperature T1 was 25 °, the current temperature T2 was 20 ℃ and the AD value at 25 ℃, i.e. the third focusing parameter AD5, was 7653.

Substituting the third focusing parameter AD5 into the formula (5) to obtain

Combining equation (3), the resistance R2 of the potentiometer at 20 ℃ is obtained:

R2＝R1+k*(T2-T1)＝1.6951+(-0.008)*(20-25)＝1.7351；

wherein, the temperature drift coefficient k1 of the lens with the focal length of 25mm takes the value of-0.008 kilo ohm/DEG C; although the temperature drift coefficient of a potentiometer in a lens of an industrial temperature measuring device is 20 ppm/DEG C, the value is small relative to k1 and can be basically equivalent to no temperature drift, so that the value of k2 is 0.

Substituting R2 into equation (4) yields AD values at 20 ℃:

the AD6 is the compensated, i.e., fifth, focus parameter (non-normalized focus parameter).

The above is a detailed description of the focus control method according to the first aspect of the present invention, but the present invention should not be limited thereto.

The focus control method of the second aspect of the present invention is applied to an electronic system including: first and second electronic devices, referring to fig. 4, the method includes the steps of:

t100: the method comprises the steps that a second electronic device receives a first focusing parameter sent by a first electronic device, wherein when the first electronic device patrols and examines a target preset point, the first electronic device obtains target preset point information of the target preset point; the target preset point information at least comprises a first focusing parameter;

t200: the second electronic device adjusts the current focusing parameters to match the first focusing parameters to focus on the target object.

When the first electronic device patrols and examines a target preset point, the first electronic device can search preset point information containing a target preset point identifier from all preset point information which is set, the searched preset point information is determined to be the target preset point information, the target preset point information at least comprises a first focusing parameter, the first focusing parameter is applied to the second electronic device, and the first focusing parameter is sent to the second electronic device. The manner of setting all the preset point information by the first electronic device can refer to the contents in the foregoing embodiments, and details are not described herein.

Of course, the target preset point information may also include other information, such as a preset point, a location of an area corresponding to the preset point, and the like, which is not limited in detail.

Since the first focus parameter is a focus parameter of the second electronic device when focusing on the target object at the time of setting the preset point, it is possible to indicate a target position where the motor is located when the lens is focused on the target object. The second electronic device adjusts the current focusing parameters to be matched with the first focusing parameters, so that a motor in a lens on the second electronic device can be quickly moved to a target position when the lens focuses on a target object, and quick focusing is realized.

For example, when a target preset point at which the first electronic device is currently located is set, the second electronic device focuses on a certain target object, and then the second electronic device adjusts the current focusing parameter of the device according to the first focusing parameter, so that the second electronic device can be quickly restored to a state of focusing on the target object to focus on the target object.

How the second electronic device adjusts the current focusing parameter of the lens on the device according to the first focusing parameter, for example, when the first focusing parameter is an unnormalized focusing parameter (a focusing parameter is directly read from the lens when a preset point is set), the second electronic device may adjust the current focusing parameter of the lens on the device to the first focusing parameter; or, when the first focusing parameter is a normalized focusing parameter (when a preset point is set, the focusing parameter after normalization processing of the focusing parameter read from the lens), the second electronic device may perform inverse normalization processing on the first focusing parameter, and then adjust the current focusing parameter of the device to the focusing parameter after inverse normalization processing. The above-described modes are only examples and are not intended to be limiting.

In one embodiment, the above method flow can be executed by a focus control apparatus, as shown in fig. 5, the focus control apparatus 200 can include 2 modules: a first focusing parameter receiving module 201 and a current focusing parameter adjusting module 202.

After the current focusing parameter of the lens on the second electronic device is adjusted to the third focusing parameter, the motor in the lens moves to the position represented by the third focusing parameter, and the position is the position where the motor is located when the lens on the second electronic device focuses on the target object when the preset point information where the first focusing parameter is located is set, so that focusing is realized.

And after receiving the second focusing parameter, the first electronic equipment sets the preset point information corresponding to the preset point according to the second focusing parameter.
