Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Example 1

Detailed description the photographing method provided by the embodiment of the application is applied to electronic equipment.

Referring to fig. 1, a flowchart of steps of a photographing method according to an embodiment of the present application is shown.

Step 101, acquiring a shooting preview screen containing the shot object, and determining color information of the shot object from the shooting preview screen.

In the embodiment of the present application, the electronic device may be an electronic device without a camera, such as a personal computer (Personal Computer, PC), a server, or the like, or an electronic device with a camera, such as a single lens reflex camera (Single Lens Reflex Camera, SLR camera), a non-reflective camera (Mirrorless Camera), a smart phone, or the like.

In the case of using an electronic device without a camera, the imaging system may be composed of the electronic device without a camera and another camera or the electronic device with a camera. For example, in the embodiment of the present application, the scheme may be applied to a personal computer, and the personal computer and the single lens are connected in a wireless or wired manner to form a shooting system together.

In the process of taking a photo, a camera function is generally required to be turned on, then, an image within a view-finding range is collected by an image sensor and a shooting preview picture is generated, the shooting preview picture is a picture collected by the image sensor, a user adjusts camera parameters, view finding angles and the like according to the shooting preview picture, and after the adjustment, a shutter is pressed to shoot an image.

In the embodiment of the application, after the shooting preview picture is acquired, the color identification of the shot object (such as a vehicle) in the shooting preview picture can be performed so as to determine the color information of the object in the shooting preview picture. The color information may include a main color of the object, or may include a duty ratio of a plurality of colors, for example, the color information of the object may be red, or the color information of the object may be (20% red+80% blue). It should be noted that the color may be represented by a color code given in a color standard, for example, color code FF0000 represents positive red, and color code FFFFFF represents pure white. The real-time examples of the present application are not particularly limited to the color standard, and a skilled person can select an appropriate color standard according to actual needs.

Specifically, in one embodiment, since the subject is usually placed in the center of the picture when taking a photo, that is, in the taking preview picture, the subject is usually in the middle area, in order to improve the efficiency of determining the color information and reduce the resource consumption, a preset area may be directly set in the center of the taking preview picture, and the color of the image in the preset area may be extracted, so as to obtain the color information of the preset area, and then the color information of the preset area is directly used as the color information of the subject. Further, the preset area can be adjusted according to the requirement of the user, and the user can adjust the size and the position of the preset area in the shooting preview picture according to the size and the position of the shot object in the shooting preview picture.

In another embodiment, in order to improve accuracy of determining the color information, the object may be actively identified to determine a position of the object in the shooting preview screen and a shape of the object in the shooting preview screen, so as to accurately extract pixel information of an area of the object in the shooting preview screen, and determine the color information of the object according to the extracted pixel information.

For example, the object in the shooting preview screen may be identified by the object identification neural network model and an area in which the object is located is determined, so that color information of the shooting preview screen in the area is acquired as the color information of the object.

Step 102, determining shooting parameters for the shot object according to the color information.

In a real shooting scene, a photographer generally needs to set shooting parameters of a camera according to colors of shot objects, so as to obtain better shooting effects for the shot objects with different colors. For example, in a scene of shooting a vehicle, because white paint reflects more light, shooting at a higher shutter speed may be required to avoid overexposure when shooting a white vehicle; the black paint reflects less light and therefore may need to be photographed at a lower shutter speed to avoid underexposure when photographing a black vehicle; the red vehicle paint reflects light with a lower color temperature (a measuring unit containing color components in the light), so that the ambient light is warm, and the image with the correct color temperature is required to be shot with a corresponding white balance value. In order to obtain good shooting effects for all the objects with different colors, various shooting parameters can be determined according to the colors of the objects, wherein the shooting parameters can include shutter speed (exposure time), white balance, aperture size, photosensitivity (ISO value) and the like.

When the shutter speed represents shooting a photo, the longer the shutter is opened, the more light rays participating in sensitization are, and under the condition that other shooting parameters are unchanged, the higher the brightness of the shot image is; otherwise, the lower the brightness of the photographed image.

The white balance setting can calibrate the deviation of the color temperature of the image, and the color of the photographed object can be well restored by setting the correct white balance in photographing. If the white balance deviates, the photographed image may shift the color of the scene itself, resulting in a warmth or coldness of the image.

The camera imaging utilizes the principle of aperture imaging, light rays are imaged on an image sensor through apertures in a lens, an aperture is a device for controlling the size of the apertures, the larger the aperture is, the larger the aperture diameter is, the more light rays which participate in imaging in unit time are, the smaller the aperture is, the smaller the aperture diameter is, and the less light rays which participate in imaging in unit time are.

The sensitivity indicates the sensitivity of a film (image sensor) used for imaging by a camera to light, and the higher the sensitivity is, the more sensitive the image sensor is to light, and the higher the brightness of the imaging result is for the same light flux.

In the embodiment of the application, a technician or a user can determine shooting parameters matched with each color information according to experience or related calculation in advance, set shooting parameters corresponding to each color information, establish color-parameter corresponding relations between the color information and one or more shooting parameters, and inquire the color-parameter corresponding relations according to the color information of the shot object after obtaining the color information of the shot object, so as to determine the required shooting parameters, wherein the color information can comprise color codes, color names or color identification codes and the like.

Further, color information of the object may be input into a preset shooting parameter determination model, so as to obtain shooting parameters output by the shooting parameter determination model. The shooting parameter determination model can be obtained based on neural network model training, and can also be a mathematical model constructed by technicians. It should be noted that, a technician may construct the above-mentioned shooting parameter determination model according to actual needs, and the form and the generation method of the shooting parameter determination model in the embodiment of the present application are not particularly limited.

And step 103, shooting the shot object based on the shooting parameters to obtain a target image.

In the embodiment of the application, after the shooting parameters are obtained, the image can be shot based on the shooting parameters. The user can also take a plurality of pictures of the same shot object by adopting the method, in this case, as the color of the same shot object is not changed, the shooting parameters can be determined by adopting the method only when shooting for the first time, and the shooting parameters determined when shooting for the first time are used in the follow-up shooting process, so that the shooting efficiency is improved, and the operation resources consumed by shooting images are reduced.

For example, a user shoots a black car in a studio, needs to shoot a plurality of photos to synthesize a panoramic animation of the black car, and then before shooting a first photo, the user can determine the color information of the black car by shooting a preview picture, and determine corresponding shooting parameters according to the color information of the black car, and shoot a plurality of photos at different angles of the black car by using the shooting parameters.

In summary, the photographing method provided by the application includes: acquiring a shooting preview picture containing a shot object, and determining color information of the shot object from the shooting preview picture; determining shooting parameters corresponding to the color information; and shooting the shot object based on the shooting parameters to obtain a target image containing the shot object. When a photo is shot, the color information of the shot object is determined through shooting the preview picture, shooting parameters matched with the color of the shot object are determined according to the color information of the shot object, and the shot object is shot according to the shooting parameters matched with the color of the shot object, so that a target image is obtained.

Example two

Referring to fig. 2, fig. 2 shows a flowchart of steps of another photographing method according to an embodiment of the present application, which may include the following steps:

step 201, acquiring a shooting preview screen containing the shot object, and determining color information of the shot object from the shooting preview screen.

In this step, reference is made to step 101, which is not repeated in the embodiment of the present application.

In addition, in the embodiment of the application, the color recognition model can also be used for determining the color category of the photographed object. The technician can train the neural network model through a training set formed by the sample image and the color labeling information corresponding to the sample image, so as to obtain a color recognition model capable of coding according to the determined color of the input image.

Optionally, step 201 may include:

and a sub-step 2011 of inputting the shooting preview picture into a color recognition model to obtain the color code output by the color recognition model.

In one embodiment, the color recognition model may include two parts, namely a shot object extraction sub-model and a color recognition sub-model, and the shot preview image may be directly input into the color recognition model, the shot object is extracted from the sub-model by the shot object to identify the shot object and determine the boundary line of the shot object, then the image part in the boundary line in the shot preview image is input into the color recognition sub-model, and the color recognition is performed on the image part in the boundary line by the color recognition sub-model, so as to determine the color coding of the shot object in the shot preview image.

In another embodiment, the color recognition model may not recognize and extract the subject in the photographing preview screen. Before the shooting preview picture is input into the color recognition model, a preset area corresponding to the shot object is set in the shooting preview picture in an automatic or manual mode, then the shooting preview picture in the preset area is input into the color recognition model, and the color recognition model is used for carrying out color recognition on the shooting preview picture in the preset area so as to determine the color coding of the shot object in the shooting preview picture.

A substep 2012 of determining a color class of the subject based on the color coding.

Millions of color codes are typically contained in a color standard library, and a broad "red" may correspond to tens of thousands of different codes, such as a pink code of FFC0CB, a deep red code of DC143C, and so on. In the embodiment of the application, based on cost performance consideration, the corresponding shooting parameters may not need to be set for each color code, and the shooting requirements may be met by only setting tens or hundreds of small shooting parameters. Thus, color codes may be categorized, with multiple color codes corresponding to one color category, where a color category may include red, green, blue, purple, and the like.

For example, the technician may set 14 color categories of black, white, silver, gray, red, blue, green, yellow, orange, brown, purple, gold, powder, champagne, and associate each color code with one of the 14 color categories, so that after the color codes are obtained, the color category to which the color codes correspond is determined.

In the embodiment of the application, the color recognition model is enabled to output the color codes, and then the color codes are converted into the color categories, so that the color recognition model can be conveniently modified by a technician by increasing, decreasing, deleting, modifying and the like the color categories, after the color categories are modified, the color recognition model is not required to be modified, only the corresponding relation between the color parameters and the color categories is required to be re-established, and the maintainability is improved. The color recognition model may be trained to output the color class directly.

Step 202, obtaining a corresponding relation of target parameters, wherein the corresponding relation of the target parameters comprises a corresponding relation of color information and shooting parameters.

In the embodiment of the application, a technician or a user can determine shooting parameters matched with each color information according to experience or related calculation in advance, set shooting parameters corresponding to each color information, establish a target parameter corresponding relation between the color information and one or more shooting parameters, and query the target parameter corresponding relation according to the color information of the shot object after obtaining the color information of the shot object, thereby determining required shooting parameters, wherein the color information can comprise color categories.

Further, according to the different object types of the photographed objects, even if the color information is the same, different photographing parameters may be required to be adopted for photographing, so that a better photographing effect can be obtained for different types of photographed objects. The object type may represent, among other things, the kind of object, such as a vehicle, a person, a building, a plant, etc. Therefore, the technician can set a plurality of sets of parameter corresponding relations for different object types, and each set of parameter corresponding relation corresponds to one object type. Thus, the corresponding target parameter corresponding relation can be determined according to the object type of the shot object.

Specifically, the following methods of the sub-steps 2021 to 2022 may be employed to determine the target parameter correspondence relationship corresponding to the subject.

Step 202 may include:

sub-step 2021, determining an object type of the subject.

In the embodiment of the application, the object type option can be provided for the user to select the object type corresponding to the shot object to be shot. The object type determination model may also be trained in advance, and the object in the shooting preview screen may be identified by the object type determination model, so as to determine the object type of the object. It should be noted that, the method for determining the object type of the object can be flexibly selected by a technician according to actual needs, and the embodiment of the present application is not limited in particular.

Sub-step 2022, determining the corresponding target parameter correspondence according to the object type.

In the embodiment of the application, the corresponding relation between the object type and the parameter corresponding relation can be further included, and after the object type of the shot object is determined, the corresponding relation between the object type and the parameter corresponding relation can be determined according to the corresponding relation between the object type and the parameter corresponding relation.

Step 203, determining shooting parameters corresponding to the color information of the shot object according to the target parameter corresponding relation.

Because the corresponding relation between the target parameters includes the corresponding relation between the color information and the shooting parameters, after the corresponding relation between the target parameters of the shot object is obtained, the shooting parameters corresponding to the shot object can be determined according to the color information of the shot object. Therefore, the shot object can be photographed through the photographing parameters in the subsequent process, and a good photographing effect is achieved.

Step 204, determining a current size of the subject in a shooting preview screen, and a target size set for the subject.

In a plurality of shooting scenes, it is generally necessary to take a plurality of corresponding photos at a plurality of angles of the same subject, and to perform a plurality of compositing. Not only the shooting parameters between the plurality of images obtained by the plurality of shooting are required to be the same, but also the sizes of the objects in the plurality of images are required to be the same so as to perform the post-image composition. However, in order to capture a plurality of images, it is necessary to adjust the relative position between the subject and the camera, which may cause a change in the distance between the subject and the camera during the adjustment, thereby affecting

Therefore, in order to further improve convenience in a plurality of shooting scenes, in the embodiment of the present application, the size of the object in the shooting preview screen may be automatically adjusted before each shooting of the image, so that the size of the object in the shooting preview screen is the same in the image obtained by each shooting.

Specifically, the subject in the shooting preview screen may be identified, and the current size of the subject in the shooting preview screen may be determined, and if the current size does not coincide with the target size, the size of the subject in the shooting preview screen may be adjusted to the target size. The size may be a width ratio, a height ratio, an area ratio, or the like of the subject in the photographing preview screen.

The target size may be set by the photographer before photographing, and for example, the target size may be set to 1/2 of the width of the photographed preview screen or the target size may be set to 1/3 of the height of the photographed preview screen. In addition, the size of the subject in the first image captured during one multi-shot process may be determined as the target size, so that the size of the subject in each image captured subsequently during the one multi-shot process is the same as the size of the subject in the first image. For example, when a user needs to take a group of (10) vehicle photos for generating a panoramic animation of the vehicle, during taking a first photo, the user can directly take the photo without adjusting the size of the shot object according to the target size, and determine that the size of the shot object in the first image obtained by taking the photo is 1/2 of the width of a shooting preview screen, when taking the subsequent 9 images, each taking the 1/2 of the width of the shooting preview screen as the target size of the shot object, so that the sizes of the shot objects in the 10 images obtained by taking the photo this time are the same.

Step 205, adjusting the size of the object to the target size.

In the embodiment of the present application, the camera for photographing the subject may be a camera including a zoom function (optical zoom and/or digital zoom), and the size of the subject in the photographing preview screen may be changed by adjusting the focal length of the camera.

The camera for shooting the shot object can also be a camera mounted on a sliding rail or a mobile device, the camera can change the relative position between the camera and the shot object through the sliding rail or the mobile device, thereby changing the distance between the camera and the shot object, and the size of the shot object in a shooting preview picture can be adjusted based on the principle of near-far.

Optionally, step 205 may include:

in a substep 2051, the camera focal length is increased if the current size is smaller than the target size.

In the embodiment of the application, for the shooting equipment with an automatic zooming function, the automatic zooming can be directly carried out by controlling the shooting equipment, so that the size adjustment of a shot object is realized, for the shooting equipment which is not provided with the automatic zooming function but is only provided with a manual zooming function, for example, a single-lens reflex camera with a manual zooming ring is carried, a zoom device (such as a Kaffy zoom device) with a servo motor can be arranged on the zooming ring of the camera, and the zoom ring is driven to rotate by controlling the rotation of the servo motor so as to control the focal length of the camera, so that the size adjustment of the shot object in a shooting preview picture is realized. The zoom device can establish wired or wireless communication with the electronic equipment, receives a zoom control instruction sent by the electronic equipment, and drives a driving motor connected with the zoom ring to act according to the zoom control instruction, so that the control of the focal length of the camera is realized.

If the current size of the shot object is smaller than the target size, the focal length of the camera needs to be increased, the effect of 'zooming in' the shot object is achieved, and the size of the shot object in a shooting preview picture is increased until the target size.

Substep 2052, reducing the camera focal length in case the current size is larger than the target size.

If the current size of the shot object is larger than the target size, the focal length of the camera needs to be reduced, the effect of 'pushing away' the shot object is realized, and the size of the shot object in a shooting preview picture is reduced until the target size.

And step 206, shooting the shot object based on the shooting parameters to obtain a target image.

In this step, reference may be made to step 103, which is not described in detail in the embodiments of the present application.

In a substep 2061, a view angle distance for the subject is acquired.

The user can set the surrounding angle range to be shot and the number of images to be shot, and the framing angle interval between two adjacent images can be calculated according to the surrounding angle range and the number of images, for example, the surrounding angle range set by the user is 360 degrees, the number of images to be shot is 10, then the shooting device can be automatically controlled to rotate around the shot object, and the shooting device can shoot 10 images around the shot object with 36 degrees as the framing angle interval.

Substep 2062, controlling a camera to move around the shot object, and shooting the shot object at the view angle interval to obtain a plurality of target images containing the shot object, wherein the target images are shot based on the shooting parameters.

In the embodiment of the application, the shooting device can comprise the shooting device capable of moving autonomously, so that the shooting of the shot object from different angles is realized automatically, and the shooting device can be formed by a camera and an annular turntable. Referring to fig. 3, fig. 3 shows a schematic diagram of a photographing apparatus according to an embodiment of the present application, where, as shown in fig. 3, the photographing apparatus may include an electronic apparatus 31, a camera 32 connected (wirelessly connected or wired connected) to the electronic apparatus, and a turntable 33 connected to the electronic apparatus, the camera 32 is disposed on the turntable 33, and the camera 32 may photograph a subject 34 at different viewing angles under rotation of the turntable 33.

Referring to fig. 4, fig. 4 shows a shooting control logic diagram provided by the embodiment of the present application, as shown in fig. 4, an electronic device may be connected to a programmable logic controller (Programmable Logic Controller, PLC) in a wired or wireless manner, and the electronic device sends a rotation control signal to the programmable logic controller through a Modbus protocol, and after receiving the rotation control signal, the programmable logic controller sends a driving signal to a servo motor connected with the rotation control signal to control the servo motor to drive a turntable on which a camera is disposed to rotate, so as to adjust a shooting angle of the camera on a shot object. The electronic equipment can be connected with the zoom device in a wired or wireless mode, and the zoom device is driven to drive the zoom ring of the camera to rotate by sending a zoom control signal to the zoom device, so that the focal length of the camera is adjusted. The electronic device may also connect to the camera by wired or wireless means to control various functions of the camera, such as acquiring a photographing preview picture from the camera, transmitting photographing parameters to the camera, controlling the camera to photograph an image, and the like.

It should be noted that, in the process of photographing around the object, the photographing parameters may be set and the focal length of the camera may be adjusted by using the method in the foregoing steps. In addition, the technician may set up the photographing device capable of moving automatically in other manners, such as an unmanned vehicle carrying a camera, which is not particularly limited in the embodiment of the present application.

According to the embodiment of the application, the surrounding shooting of the shot object can be automatically realized, the shooting parameters are automatically set according to the information such as the color of the shot object in the shooting process, and meanwhile, the sizes of the shot objects in a plurality of images obtained by the surrounding shooting can be unified in an automatic zooming mode and the like, so that the shooting convenience and the shooting efficiency are improved.

In this step, reference is made to step 201, and the description of the embodiment of the present application is omitted.

Step 302, determining material information of the object.

In addition to the effect of the image, the color of the object may have a large influence on the image. For example, if the material of the object is a mirror surface material or a smooth surface material, the surface glossiness is high, the reflectivity is high, and if the surface of the object is a frosted material or a matte material, the surface glossiness is low, and the reflectivity is low. In order to obtain a good imaging effect, it is generally necessary to set different imaging parameters in order to image objects of different materials.

In the embodiment of the application, the shooting parameters can be determined according to the material information of the shot object, so that good shooting effects can be obtained for the shot objects with different materials.

Specifically, the shooting preview picture is input into a preset material detection model, so that the material information output by the material detection model is obtained. The material detection model can be obtained based on neural network model training, and can also be a mathematical model constructed by technicians. It should be noted that, a technician may construct the above material detection model according to actual needs, and the form and the generation method of the material detection model in the embodiment of the present application are not limited specifically. Wherein, the material information may include a bright surface material, a matte material, and the like.

In addition, the reflectivity of the object may be detected by the laser sensor, so that the material information of the object is determined according to the reflectivity. The laser sensor can send the emission light beam with preset intensity to the shot object, receive the reflection light beam of the shot object to the light beam with preset brightness, and can determine the reflectivity of the shot object according to the ratio between the intensity of the emission light beam and the intensity of the reflection light beam.

Step 303, determining shooting parameters for the shot object based on the color information and the material information.

In one embodiment, after obtaining the color information and the texture information of the object, the shooting parameters corresponding to the color information and the texture information of the object may be determined according to the correspondence between the color information, the texture information and the shooting parameters. The corresponding relationship of the three can be preset by a technician or a user according to actual needs, and the application does not limit the corresponding relationship of the three.

In another embodiment, after obtaining the color information and the material information of the object, the method in the above steps may be adopted to determine the shooting parameters corresponding to the object according to the color information of the object, and then correct the shooting parameters corresponding to the object according to the material information of the object. For example, if the material information of the object is a matte material, the exposure time can be prolonged, the sensitivity can be increased, the aperture size can be increased, or the like, and the exposure amount at the time of capturing an image can be increased.

In the embodiment of the application, the shooting parameters for the shot object can be determined according to the color information of the shot object, and the shooting parameters for the shot object can be determined according to the color information and the material information of the shot object, so that the shooting effect and the shooting efficiency of shooting the shot objects with different colors and materials are further improved.

Step 304 of determining a current size of the subject in a photographing preview screen, and a target size set for the subject.

In this step, reference is made to step 204, and the description of the embodiment of the present application is omitted.

Step 305, adjusting the size of the object to the target size.

This step can be referred to as step 205, and the embodiments of the present application will not be described again.

And step 306, shooting the shot object based on the shooting parameters to obtain a target image.

This step can be referred to as step 206, and the embodiments of the present application will not be described again.
