Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to determine a target area beyond a monitoring screen, embodiments of the present application provide an area determination method, a system, an apparatus, and an electronic device, which are described in detail below.

Referring to fig. 1, fig. 1 is a schematic flowchart of a method for determining a region according to an embodiment of the present disclosure, where the method may be applied to electronic devices such as a computer, a tablet computer, and a mobile phone. As shown in fig. 1, the area determination method includes the following steps 101 to 103.

Step 101, at least two target monitoring pictures are obtained.

Wherein, the target monitoring picture is: and the monitoring equipment acquires monitoring pictures containing the mark points of the target area under different pan-tilt control parameters. The marker points in the target area are not in the same monitoring picture.

The Pan/Tilt/Zoom control parameter may include an azimuth angle control parameter, a lens Zoom control parameter, and a lens Zoom control parameter of the monitoring device, and the Pan/Tilt/Zoom control parameter may be a PTZ (Pan/Tilt/Zoom) parameter. Under different pan-tilt control parameters, the azimuth angle, the lens multiple and the lens focal length of the monitoring equipment can be changed, so that the monitoring pictures acquired by the monitoring equipment are different.

The target area may be a shielded area in which the user does not wish to perform intelligent analysis in the monitored area, or may be a special area in which the user wishes to perform special event detection in the monitored area, where the special event may be illegal parking, illegal turning, occupation of a fire fighting access, or may be an area in which important monitoring is desired in the monitored area, such as a cashier area, a safe escape area, and the like.

In the case where the target region is a polygonal region or an irregular region, the mark points may be vertices, edge points, or the like of the target region; in the case where the target area is a circular area, the mark point may be a center of the target area, an edge point, or the like.

All the mark points of the target area are not in the same monitoring picture. For example, if the mark point of the target area includes the left end point and the right end point of the target area, it is difficult for the monitoring screen acquired by the monitoring device to include both the left end point and the right end point when the width of the target area is large.

Specifically, the monitoring device may collect a monitoring picture of the monitoring area, and send the collected monitoring picture to the electronic device. And when the monitoring equipment is in different pan-tilt control parameters, the electronic equipment can obtain different monitoring pictures. The electronic device may select at least two different monitoring pictures containing the landmark points of the target area from the received monitoring pictures as target monitoring pictures, that is, each target monitoring picture contains at least one landmark point of the target area.

In an embodiment of the present application, the selected landmark points included in each target monitoring screen are different, and the landmark points included in all the target monitoring screens satisfy the target area determination condition.

Wherein the target area determination condition is: the condition of the target area can be uniquely determined according to the determined marker point. For example, when the target area is a quadrilateral area and the marker point is a vertex of the target area, the target area determination condition may be: the marker points included in all the target monitoring pictures include four vertices of the target area.

The number of target monitoring pictures thus selected may be less than or equal to the number of target area marker points, for example, in the case where the target area is a quadrilateral area and the marker points are vertices of the target area, the number of marker points may be 4, and the number of monitoring pictures thus selected may not exceed 4; when the target area is a circular area and the marker points are the center of the target area, the number of the marker points may be 1, and the number of the selected monitoring screens is 1. Therefore, the repeated determination of the same mark point in different monitoring pictures can be avoided, the number of the selected monitoring pictures can be reduced, and the area determination efficiency is improved.

When the target area is circular or fan-shaped, the radius and the angle can be determined besides the center of the circle of the mark point, so that the target area can be determined according to the center of the circle, the radius and the angle.

In an embodiment of the application, the monitoring device can change the control parameters of the cradle head according to the preset control rule of the cradle head, so that the monitoring picture is collected under different control parameters of the cradle head, and the collected monitoring picture is sent to the electronic device. The pan/tilt control rule may be: changing the azimuth stepwise from left to right, from bottom to top, etc.

In another embodiment of the application, the electronic device may further send a cradle head adjustment instruction to the monitoring device, and instruct the monitoring device to change the cradle head control parameter according to the cradle head adjustment instruction, so that the monitoring device collects the monitoring picture under different cradle head control parameters.

Specifically, the electronic device may receive a target pan-tilt control parameter input by a user, generate a pan-tilt adjustment instruction according to the target pan-tilt control parameter, and send the pan-tilt adjustment instruction to the monitoring device, so that the monitoring device performs setting according to the target pan-tilt control parameter;

or, the electronic device may deploy, in advance, an adjustment button representing a pan/tilt adjustment manner in the operation page, where the pan/tilt adjustment manner includes upward adjustment, downward adjustment, leftward adjustment, rightward adjustment, and the like. The electronic equipment can receive the selection operation of the user on the adjusting button, generate a holder adjusting instruction according to the adjusting mode selected by the user and send the holder adjusting instruction to the monitoring equipment, so that the monitoring equipment can adjust holder control parameters according to the adjusting mode.

And 102, determining at least one mark point of the target area in each target monitoring picture.

Specifically, since the target monitoring picture obtained by the electronic device is a monitoring picture which is acquired by the monitoring device under different pan-tilt control parameters and contains the mark point of the target area, at least one mark point of the target area can be respectively determined in each target monitoring picture.

In an embodiment of the application, for step 102, when the mark point is determined in the target monitoring screen, a selection operation of the user on the mark point in the target monitoring screen through an input device may also be received, and the selected point is taken as a mark point including the target area.

And image analysis can be carried out on the target monitoring pictures so as to determine the mark points in each target monitoring picture. For example, a marker in the target monitoring screen may be detected, and the position of the detected marker may be determined as a marker point.

And 103, sending a target area determination instruction to the monitoring equipment.

Wherein the target area determination instructions are for instructing the monitoring device to determine the target area based on the determined marker point.

Specifically, after determining the mark point, the electronic device may send a target area determination instruction to the monitoring device, and after receiving the instruction, the monitoring device may determine the target area directly according to the determined mark point.

In an embodiment of the application, after receiving the target area determination instruction, the monitoring device may further obtain positions of the respective mark points based on the instruction, so as to connect the mark points to obtain a polygonal area, an irregular area, or the like, and use the obtained area as the target area.

In an embodiment of the application, after determining a mark point, an electronic device may detect a scene position of the mark point in a monitored scene, and generate a target area determination instruction carrying the scene position, and a monitoring device receives the instruction, obtains the scene position of the mark point, and determines a target area according to the scene position.

In an embodiment of the present application, after the monitoring device determines the target area, the monitoring device may add area information of the target area in a video code stream. The area information may include information such as a position and a size of the target area. Therefore, the information of the target area can be obtained according to the video code stream.

For example, in the case that the target area is a mask area, the information of the mask area may be added to the video stream, so that the subsequent intelligent analysis of the video stream may not be performed on the picture of the mask area.

When the scheme provided by the embodiment is applied to area determination, at least two target monitoring pictures can be obtained, wherein the target monitoring pictures are as follows: monitoring pictures which are acquired by monitoring equipment under different pan-tilt control parameters and contain the mark points of the target area, wherein the mark points which are not in the same monitoring picture exist in each mark point of the target area; determining at least one mark point of a target area in each target monitoring picture; and sending a target area determination instruction to the monitoring device, wherein the target area determination instruction is used for instructing the monitoring device to determine a target area based on the determined mark point. Therefore, each mark point of the target area can be respectively set in the target monitoring picture acquired by the monitoring equipment under different pan-tilt control parameters, and then the monitoring equipment can determine the target area according to each set mark point. Therefore, the area determining scheme provided by the embodiment can be used for determining the target area beyond the monitoring picture.

In an embodiment of the present application, the target area determining instruction in step 103 may be configured to: and instructing the monitoring equipment to determine a target area based on the position characterization parameters corresponding to the determined mark points.

Wherein, the position characterization parameters corresponding to each marking point are as follows: and under the condition that the mark point is positioned at the specified position of the target monitoring picture acquired by the monitoring equipment, monitoring the cradle head control parameters of the monitoring equipment.

In an embodiment of the present application, the specified position may be a central position of the target monitoring screen, and the position characterizing parameters corresponding to the mark point are: and under the condition that the mark point is positioned at the central position of the monitoring picture collected by the monitoring equipment, monitoring the cradle head control parameters of the monitoring equipment. That is, in this case, the position characterizing parameter corresponding to each landmark point can be understood as: and monitoring the pan-tilt control parameters when the equipment is directly opposite to the mark point. Therefore, when the designated position is the center position of the monitoring picture, the current holder control parameter of the monitoring device can be directly determined as the position characterization parameter corresponding to the mark point subsequently, so that the resource consumption caused by calculating the position characterization parameter is saved.

Besides, the target mark position may be a lower left corner position, an upper right corner position, or the like of the monitoring screen.

Under the above circumstances, the target mark position may be obtained in advance in the monitoring device, so that the monitoring device may determine the position of the mark point according to the target mark position from the monitoring picture acquired under the position characterizing parameter after obtaining the position characterizing parameter of the mark point subsequently.

Specifically, after the electronic device sends a target area determining instruction to the monitoring device, the monitoring device may determine a position characterizing parameter corresponding to the mark point, so as to determine the target area according to the position characterizing parameter.

In an embodiment of the application, after each mark point is determined, the electronic device may send an instruction to the monitoring device, and the monitoring device determines the position characterizing parameter corresponding to the mark point based on the instruction. After the determined mark points satisfy the area determination condition, the electronic device may send a final target area determination instruction to the monitoring device, and after receiving the target area determination instruction, the monitoring device determines the target area according to the determined position characterization parameters of each mark point.

In another embodiment of the present application, after the determined mark points satisfy the area determination condition, the electronic device may send a target area determination instruction to the monitoring device, and the monitoring device may determine the position characteristic parameters of the mark points based on the target area determination instruction, and determine the target area according to the determined position characteristic parameters of the mark points. Therefore, the instruction interaction process between the electronic equipment and the monitoring equipment can be reduced, and the area determination efficiency is improved.

In an embodiment of the present application, when the monitoring device determines the location characterizing parameter of the landmark point, based on data interaction between the electronic device and the monitoring device, the following parameter determining manner may be included:

in a first mode, after determining the mark point, the electronic device may determine a position characterizing parameter corresponding to the mark point, and then send an instruction carrying the position characterizing parameter to the monitoring device, and the monitoring device receives the instruction, so as to obtain the position characterizing parameter of the mark point carried in the instruction.

In a second mode, after determining a mark point, the electronic device may obtain the position information of the mark point in the monitoring picture, and send an instruction carrying the position information to the monitoring device, and the monitoring device receives the instruction, so as to obtain the position information of the mark point carried in the instruction, and obtain the position characterizing parameter corresponding to the mark point according to the position information and the preset specified position.

In a third mode, under the condition that the mark point is located at the designated position of the monitoring picture, because the position characterization parameter corresponding to the mark point is the current pan-tilt control information of the monitoring device, the electronic device can directly send an instruction to the monitoring device after determining the mark point, and the monitoring device obtains the pan-tilt control information of the pan-tilt as the position characterization parameter corresponding to the determined mark point after receiving the instruction.

In an embodiment of the present application, when determining a location characterizing parameter corresponding to a landmark point based on location information of the determined landmark point in a monitoring picture, the following two situations are included:

in case one, the marker point is located at a designated position of the monitoring screen. In this case, the pan-tilt control parameter of the monitoring device can be directly obtained as the position characterizing parameter corresponding to the mark point.

In case two, the determined landmark point is not at the designated position of the monitoring screen. In this case, the target area determination instruction may carry: and the position information of the determined mark point in the target monitoring picture or the offset information of the determined mark point relative to the specified position in the target monitoring picture.

The target area determination instruction may be configured to instruct the monitoring device to: and determining offset information of the mark point of the target area relative to a specified position in the target monitoring picture, and calculating a position characterization parameter corresponding to the mark point according to the determined offset information and the current holder control parameter of the monitoring equipment.

Specifically, the electronic device may directly obtain position information of the determined mark point in the monitoring picture, generate a target area determination instruction carrying the position information, and after receiving the instruction, the monitoring device obtains the position information of the mark point, then calculates offset information of the position information with respect to a preset specified position, and calculates a position characterizing parameter of the mark point based on the offset information and a pan-tilt control parameter of the monitoring device.

The electronic equipment can also obtain the position information of the determined mark point in the monitoring picture, calculate the offset information of the position information relative to a preset specified position, then generate a target area determination instruction carrying the offset information, obtain the offset information of the mark point after the monitoring equipment receives the instruction, and calculate the position representation parameter of the mark point based on the offset information and the holder control parameter of the monitoring equipment.

In an embodiment of the present application, when the target monitoring screen is selected in step 101, a selection operation of the monitoring screen by the user through an input device may be received, and the selected monitoring screen is used as the target monitoring screen including the target area mark point.

The input device may be a mouse, a keyboard, a touch pad, a voice command receiving device, etc.

Specifically, the electronic device can display the received monitoring picture acquired by the monitoring device under different pan-tilt control parameters, and in the display process, the user can execute a selection operation on the displayed monitoring picture through the input device, so that the electronic device determines the monitoring picture selected by the user as the target monitoring picture.

In another embodiment of the application, the electronic device may further perform image analysis on the monitoring pictures, analyze whether each monitoring picture includes a mark point of the target area, and determine the monitoring picture including the mark point of the target area as the target monitoring picture.

Specifically, a marker representing a marker point of the target area may be preset, and the marker may be a small red flag, a ground mark, a building mark, or the like. The electronic equipment can analyze the images of the monitoring picture, and when the monitoring picture obtained through analysis contains the marker, the monitoring picture is determined to be a target monitoring picture containing the marker point of the target area.

In an embodiment of the present application, when determining the mark point, a cradle head adjustment instruction may be sent to the monitoring device, the monitoring device is controlled to adjust the acquired target monitoring picture by adjusting a cradle head control parameter, and a point located at a target mark position of the acquired target monitoring picture is determined as a mark point of the target area when the acquired target monitoring picture meets a mark requirement.

Wherein the flag requirements include: the mark point expected to be set is at the target mark position of the target monitoring picture.

Specifically, the electronic device can send a cradle head control instruction to the monitoring device, and the monitoring device adjusts the control parameters of the cradle head of the monitoring device after receiving the instruction, so that the collected target monitoring picture is changed. In the case where the marker point that the user desires to set in the acquired target monitoring screen is at the target marker position, a point at the target marker position in the acquired monitoring screen may be determined as the marker point.

In an embodiment of the application, the target mark position may be a center position of the monitoring screen, so that a point of the center position of the target monitoring screen may be determined as a mark point.

Besides, the target mark position can be the upper left corner position, the middle upper position and the like of the monitoring picture.

In an embodiment of the present application, a preset identifier may be preset on a display window for displaying a monitoring picture, where the preset identifier corresponds to the target mark, the preset identifier may be a crosshair, a circle, an X-shaped symbol, or the like, and the color of the preset identifier may be red, blue, yellow, or the like. The preset mark set in this way can not move along with the monitoring picture, so that a user can conveniently judge whether the expected mark point is in the target mark position by observing whether the mark point of the target area expected to be set is superposed with the preset mark.

In an embodiment of the present application, the target area determining instruction in step 103 may be configured to: and instructing the monitoring equipment to determine a target area based on the determined position characterization parameters corresponding to the mark points, wherein the position characterization parameters corresponding to each mark point are as follows: and under the condition that the mark point is positioned at the target mark position of the target monitoring picture acquired by the monitoring equipment, monitoring the cradle head control parameters of the monitoring equipment.

Specifically, the designated position and the target mark position may be set to be the same position. Therefore, the cradle head control parameters of the monitoring equipment can be adjusted to enable the expected mark point to be located at the target mark position of the collected monitoring picture, and when the position characterization parameters of the mark point are obtained subsequently, the cradle head control parameters of the monitoring equipment can be directly used as the position characterization parameters of the mark point because the position characterization parameters of the mark point are the cradle head control parameters of the monitoring equipment when the mark point is located at the target mark position, and the offset information of the position information of the mark point relative to the specified position does not need to be calculated, so that the calculation amount can be reduced, and the area determination efficiency can be improved.

In one embodiment of the application, when the monitoring device is controlled to adjust the monitoring picture, an expected mark point of a target area expected to be set can be determined in a target monitoring picture acquired by the monitoring device currently, a pan-tilt adjusting instruction carrying position information of the determined expected mark point is sent to the monitoring device, so that the monitoring device calculates a target pan-tilt control parameter for adjusting a pan-tilt so that the expected mark point is located at a target mark position of the target monitoring picture according to a current pan-tilt control parameter and the current position information, and adjusts the pan-tilt according to the target pan-tilt control parameter.

Wherein, the expected mark points are as follows: a user desired, target area landmark.

Specifically, a point selected by a user in a target monitoring picture through an input device can be received as an expected mark point, or a point determined in the target monitoring picture through an image analysis mode is used as the expected mark point, then a pan-tilt adjustment instruction carrying position information of the expected mark point is generated, the generated pan-tilt adjustment instruction is sent to a monitoring device, and after the monitoring device receives the pan-tilt adjustment instruction, a target pan-tilt control parameter can be calculated based on a current pan-tilt control parameter and the position information carried in the pan-tilt adjustment instruction, and the pan-tilt is adjusted according to the target pan-tilt control parameter, so that a preset specified position of the target monitoring picture acquired after the pan-tilt is adjusted is the expected mark point.

In an embodiment of the present application, if the location characterization parameter corresponding to each landmark point is: and under the condition that the mark point is positioned at the target mark position of the target monitoring picture acquired by the monitoring equipment, the holder control parameter of the monitoring equipment, namely the specified position and the target mark position are the same position. Since the target pan-tilt control parameters are used such that: the expected mark point is located at the target mark position of the target monitoring picture, that is, the target pan-tilt control parameter is the same as the position characterization parameter corresponding to the expected mark point. Therefore, after the target holder control parameters are obtained through calculation, the monitoring equipment can directly take the target holder control parameters as the position characterization parameters corresponding to the mark points, and the position characterization parameters of the mark points do not need to be obtained subsequently, so that the calculation amount can be reduced, and the area determination efficiency is improved.

In one embodiment of the application, the electronic device may determine an adjustment operation to adjust the displayed target monitoring screen; and sending a holder adjusting instruction to the monitoring equipment based on the adjusting operation so that the monitoring equipment adjusts the holder control parameters according to the holder adjusting instruction.

Wherein, the adjusting operation may be: the user drags the target monitoring picture by using a mouse, moves the target monitoring picture by using an arrow moving instruction and the like.

Specifically, the user can adjust the target monitoring picture through the input device, the electronic device can receive the adjustment operation, a cradle head adjustment instruction is generated based on the adjustment operation and is sent to the monitoring device, and the monitoring device adjusts the cradle head according to the instruction after receiving the instruction, so that the collected target monitoring picture follows the adjustment operation input by the user.

In an embodiment of the application, the electronic device may also determine an adjustment operation for adjusting the displayed target monitoring picture, and send a pan-tilt adjustment instruction to the monitoring device based on the adjustment operation, so that the monitoring device adjusts pan-tilt control parameters according to the pan-tilt adjustment instruction. The expected mark point can be moved to a conveniently selected position in the monitoring picture by the adjusting mode.

And then determining an expected mark point of the target area expected to be set in a target monitoring picture currently acquired by the monitoring equipment, sending a pan-tilt adjusting instruction carrying position information of the determined expected mark point to the monitoring equipment, so that the monitoring equipment calculates a target pan-tilt control parameter for adjusting a pan-tilt to enable the expected mark point to be located at the target mark position of the target monitoring picture according to the current pan-tilt control parameter and the position information, and adjusts the pan-tilt according to the target pan-tilt control parameter.

Therefore, the two modes are combined, so that a user can conveniently select expected mark points in the monitoring picture, and the area determination efficiency is improved.

In an embodiment of the present application, the azimuth angles corresponding to all the landmark points of the target area may be within a preset horizontal angle range in the horizontal direction.

Wherein, the corresponding azimuth angle of each mark point is: and monitoring the azimuth angle of the equipment under the condition that the mark point is positioned in the center of the monitoring picture acquired by the monitoring equipment.

The horizontal angle range can be 2-80 degrees, 10-70 degrees, 0-90 degrees and the like. The value of the horizontal angle range can be determined according to parameters of the monitoring equipment.

Azimuth angles corresponding to all the mark points of the target area are within a preset vertical angle range in the vertical direction. The vertical angle range can be 1-45 degrees, 15-30 degrees, 0-60 degrees and the like.

Therefore, by limiting the angle range between the azimuth angles of the mark points of the target area in the horizontal direction and/or the vertical direction, the target area is prevented from being too large to cause area distortion of the subsequently determined target area, and the accuracy of the determined target area is prevented from being low.

Referring to fig. 2, fig. 2 is a schematic flowchart of another area determination method provided in the embodiment of the present application, where the method includes the following steps 201 to 206.

Step 201, receiving an area determination operation input by a user through an input device;

specifically, an area determination button may be deployed in an operation interface of the electronic device, and after receiving a selection operation of the user on the button, the user is considered to set the target area.

Step 202, obtaining the mark of the mark point to be determined;

the identifier may be a serial number of the mark point, such as 1, 2, 3 … …, and the identifier may also represent a position of the mark point, such as an upper left vertex, an upper right vertex, a circle center, a lower left corner edge point, and the like.

Specifically, a selection frame of the mark point identifier may be set in an operation interface of the electronic device, and a user may set the mark point identifier by performing a selection operation on the selection frame.

Step 203, receiving an adjustment operation of a user for adjusting the displayed monitoring picture through input equipment, and controlling the monitoring equipment to adjust the control parameters of the holder according to the adjustment operation;

specifically, a screen dragging button may be set in an operation interface of the electronic device, and a user may adjust the monitoring screen by dragging the screen dragging button.

Step 204, under the condition that the obtained monitoring picture meets the mark requirement, determining a point at the target mark position of the obtained monitoring picture as a mark point;

the target mark position may be a center position of the monitoring screen.

Step 205, sending a mark point determining instruction to the monitoring device, so that the monitoring device determines a position characterization parameter corresponding to the mark point, and returning to the step 202 until the determined mark point meets the area determining condition;

step 206, sending an area determination instruction to the monitoring device, so that the monitoring device determines the target area based on the position characterization parameters corresponding to the determined landmark points.

In an embodiment of the application, a preset identifier may be set at a central position of the monitoring screen, where the preset identifier is used to mark a target mark position, so that a user can adjust the screen to make a mark point expected to be set be at the preset identifier, and thus set the point at the preset identifier as the mark point.
