BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a flowchart of the steps of the lens configuration method described in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To describe in detail the technical content, the achieved objectives and the effects of the present invention, the following is described in conjunction with the embodiments and the accompanying drawings.

[0017] Please refer to Figure 1 , the present invention provides a lens configuration method for a multi-camera, including the following steps: S1.

[0019] Furthermore, the application requirements include monitoring scene information and monitoring object information.

[0020] Furthermore, in the step S3, based on the application requirements, generating a lens configuration scheme according to the lens ranging data set includes: Obtain the target field of view angle and the target ranging range according to the monitoring scene information; Obtain a first lens that matches the target field of view angle based on the lens ranging data set; Determine whether the effective ranging range of the first lens meets the target ranging range; If it meets the requirement, output the lens focal length information of the first lens; If it does not meet the requirement, based on the lens ranging data set, obtain a second lens according to the effective ranging range of the first lens and the target ranging range, and output the lens focal length information of the first lens and the lens focal length information of the second lens respectively.

[0021] As can be seen from the above description, the lens configuration scheme generated according to this lens configuration method can ensure that the multi-camera simultaneously meets the target field of view angle and the target ranging range, and avoid the problem of resource waste caused by configuring lenses with invalid focal lengths.

[0022] Furthermore, the monitoring scenario information includes a power transmission monitoring scenario, an urban security monitoring scenario, or an indoor monitoring scenario.

[0023] As can be seen from the above description, this lens configuration method can configure the lenses of multi-cameras applied to different types of monitoring scenarios.

[0024] Furthermore, when the monitoring scenario information includes the power transmission monitoring scenario, obtain the span of the transmission tower, and obtain the target ranging range based on the span of the transmission tower.

[0025] As can be seen from the above description, when this lens configuration method configures the lenses of a multi-camera applied to a power transmission monitoring scenario, the target ranging range can be obtained according to the span of the transmission tower to ensure the reliability and accuracy of this lens configuration method, and further ensure the reliability and ranging accuracy of the multi-camera for monitoring the power transmission monitoring scenario.

[0026] Furthermore, after step S3, it further includes the step of: generating a lens installation plan according to the application requirements and the lens configuration plan.

[0027] As can be seen from the above description, this lens configuration method for multi-cameras can also automatically generate an installation plan for the lens to ensure the reliability and ranging accuracy of the multi-camera applying this lens configuration method.

[0028] Furthermore, in step S2, obtaining the lens ranging data set includes: Configure a multi-camera with lenses of preset focal lengths, and the multi-camera respectively captures first images of the monitoring object at different distances; Input the first image into a preset target detection model to obtain the target recognition rate of the monitoring object in the first image; Obtain the first distance range corresponding to the first image whose target recognition rate is greater than the first preset value, and set the first distance range as the effective ranging range.

[0029] As can be seen from the above description, this lens configuration method can ensure the recognition rate of the lens in the lens ranging dataset for identifying the monitoring target, so as to improve the accuracy of the recognition result of the multi-camera for the monitoring object within the effective monitoring range.

[0030] Further, in step S2, obtaining the lens ranging dataset further includes: Set a number of test points according to the first distance range, and the distances between the number of test points and the monitoring object are not equal; The multi-camera respectively acquires the second images of the monitoring object at a number of the test points; Input the second images into the ranging accuracy model to obtain the ranging accuracy of the monitoring object in the second images; Obtain the second distance range corresponding to the second image whose ranging accuracy is greater than the second preset value, and update the effective ranging range according to the second distance range.

[0031] As can be seen from the above description, this lens configuration method can ensure the ranging accuracy of the lens in the lens ranging dataset for the monitoring target, so as to improve the effectiveness of the ranging result of the multi-camera for the monitoring object within the effective monitoring range.

[0032] Further, in the step S1, obtaining the application requirements of the multi-camera includes the following steps: Obtain voice information and / or text information and / or monitoring images of the monitoring scene and / or monitoring videos of the monitoring scene; When the voice information is obtained, convert the voice information into text information, extract keywords from the text information, and obtain the application requirements according to the keywords; When the text information is obtained, extract keywords from the text information, and obtain the application requirements according to the keywords; When the monitoring image and / or the monitoring video is obtained, obtain the application requirements according to the monitoring image and / or the monitoring video.

[0033] Further, the multi-camera includes a main camera and a sub-camera, and the lenses of the main camera and the sub-camera are both configured according to the lens configuration scheme.

[0034] Embodiment 1 Please refer to Figure 1 , Embodiment 1 of the present invention is: A lens configuration method for a multi-camera, which includes the following steps: S1. Obtain the application requirements of the multi-camera; S2. Obtain a lens ranging data set, where the lens ranging data set includes the effective ranging ranges of lenses with different focal lengths for different types of monitoring objects, and the field of view angle information of lenses with different focal lengths; S3. Based on the application requirements, generate a lens configuration plan according to the lens ranging data set, where the lens configuration plan includes the number of lenses and lens focal length information.

[0035] Specifically, in step S3 of this embodiment, generating a lens configuration plan based on the application requirements according to the lens ranging data set includes: Obtain the target field of view angle and the target ranging range according to the monitoring scene information; Based on the lens ranging data set, obtain a first lens that matches the target field of view angle; Determine whether the effective ranging range of the first lens meets the target ranging range; If it meets, output the lens focal length information of the first lens; If it does not meet, based on the lens ranging data set, obtain a second lens according to the effective ranging range of the first lens and the target ranging range, and output the lens focal length information of the first lens and the lens focal length information of the second lens respectively.

[0036] In some application scenarios, the target ranging range is large. When a single-focal-length lens is selected for the multi-camera, the effective ranging range of the multi-camera cannot completely cover the target ranging range. Therefore, when the effective ranging range of the first lens cannot completely cover the target ranging range, a second lens is configured to supplement and cover the ranging range of the multi-camera, so that the set of the effective ranging ranges of the first lens and the second lens completely covers the target ranging range.

[0037] The lens configuration method provided in this embodiment can configure the lenses of the multi-camera according to the application requirements, while ensuring that the field of view angle and the effective monitoring distance of the multi-camera can meet the application requirements, and avoiding the problem of resource waste caused by configuring lenses with invalid focal lengths for the multi-camera.

[0038] The application requirements described in step S1 include monitoring scene information and monitoring object information. The monitoring scene information may include, but is not limited to, a power transmission monitoring scene, an urban security monitoring scene, or an indoor monitoring scene; the monitoring object information may include, but is not limited to, construction vehicles, small cars, and pedestrians. This lens configuration method can configure the lenses of the multi-camera according to the application scenario and the monitoring object, so the universality of this lens configuration method is high.

[0039] Among them, the target ranging range of the urban safety monitoring scenario and the indoor monitoring scenario is relatively fixed, while the target ranging range of the power transmission monitoring scenario needs to be set according to the span of the transmission tower.

[0040] Therefore, in this embodiment, it further includes the steps of: when the monitoring scenario information includes the power transmission monitoring scenario, obtaining the span of the transmission tower, and obtaining the target ranging range based on the span of the transmission tower. Obtaining the target ranging range according to the span of the transmission tower can ensure the accuracy and reliability of the multi-camera for monitoring the power transmission monitoring scenario.

[0041] In this embodiment, the multi-camera includes a main camera and a secondary camera, and the lenses of the main camera and the secondary camera are both configured according to the lens configuration scheme.

[0042] Briefly speaking, the lens configuration of the main camera is the same as that of the secondary camera. As an example: when the main camera is configured with a first lens and a second lens, the secondary camera is configured with the same first lens and second lens.

[0043] After step S3 of the lens configuration method provided in this embodiment, it further includes the step of: generating a lens installation scheme according to the application requirements and the lens configuration scheme. Specifically, the lens installation scheme includes installation position information and installation height information. The lens configuration method of this multi-camera can also automatically generate the installation scheme of the lens to ensure the reliability and ranging accuracy of the multi-camera applying this lens configuration method.

[0044] For the convenience of understanding, this embodiment provides the following application examples: The lens ranging data set includes the effective ranging ranges of lenses with focal lengths of 4mm, 8mm, 16mm, 25mm, 35mm, and 50mm for different monitoring objects, as well as the field of view angle information of the distance range of the target ranging range.

[0045] Application Example 1: The application requirements include a power transmission monitoring scenario with a span of 300 meters for a transmission tower, and the monitoring object is a baseline with a height of more than 5 meters. Based on the above application requirements, it is determined from the lens ranging dataset that a single-focal-length lens cannot fully cover the monitoring range of 300 meters. Therefore, a lens with a focal length of 8 mm and a lens with a focal length of 25 mm are selected, that is: both the main camera and the secondary camera of the multi-camera are configured with a lens with a focal length of 8 mm and a lens with a focal length of 25 mm. According to the application requirements and the lens configuration scheme, the main camera and the secondary camera are respectively installed on both sides of the transmission tower at a height of 20 to 30 meters. Among them, the field of view angle of the lens with a focal length of 8 mm can cover the entire monitoring scenario, and the multi-camera can complete the application requirements of high-precision ranging and modeling within 200 m through the lens with a focal length of 8 mm. The multi-camera can meet the application requirements of high-precision ranging and modeling within the range of 200 m to 300 m through the lens with a focal length of 25 mm.

[0046] Application Example 2: The application requirements include a power transmission monitoring scenario with a span of 500 meters for a transmission tower, and the monitoring objects include a baseline with a height of more than 5 meters. Based on the lens ranging dataset, according to the above application requirements, a lens with a focal length of 8 mm and a lens with a focal length of 35 mm are selected, that is: both the main camera and the secondary camera of the multi-camera are configured with a lens with a focal length of 8 mm and a lens with a focal length of 35 mm. According to the application requirements and the lens configuration scheme, the main camera and the secondary camera are respectively installed on both sides of the transmission tower at a height of 50 meters. Among them, the field of view angle of the lens with a focal length of 8 mm can cover the entire monitoring scenario, and the multi-camera can complete the application requirements of high-precision ranging and modeling within 200 m through the lens with a focal length of 8 mm. The multi-camera can meet the application requirements of high-precision ranging and modeling within the range of 200 m to 500 m through the lens with a focal length of 35 mm.

[0047] Application Example 3: The application requirements include an urban security monitoring scenario with a monitoring range within 20 meters. Based on the lens ranging dataset, according to the above application requirements, a lens with a focal length of 4 mm and a lens with a focal length of 8 mm are selected, that is: both the main camera and the secondary camera of the multi-camera are configured with a lens with a focal length of 4 mm and a lens with a focal length of 8 mm. According to the application requirements and the lens configuration scheme, the main camera and the secondary camera are respectively installed on the building wall at a height of 5 meters. Among them, the field of view angle of the lens with a focal length of 4 mm is larger, and the multi-camera can meet the application requirements of high-precision ranging and modeling within a short distance of 20 m through the lens with a focal length of 4 mm. The multi-camera can meet the application requirements of high-precision ranging and modeling beyond 20 m at a short distance through the lens with a focal length of 8 mm.

[0048] Application Example 4: The application requirements include an indoor monitoring scenario. In the indoor monitoring scenario, the distance between the multi-camera and the monitoring object is very close, and the installation height of the multi-camera is low. Therefore, a lens with a focal length of 4 mm is selected, that is: both the main camera and the secondary camera of the multi-camera are configured with a 4 mm lens. According to the application requirements and the lens configuration scheme, the target ranging range in the indoor monitoring scenario is small, and the main camera and the secondary camera can be integrated into the same housing and installed on the corner of the room to balance the requirements of a large field of view and close-range monitoring.

[0049] In step S1 of this embodiment, obtaining the application requirements of the multi-camera includes the following steps: Obtaining voice information and / or text information and / or monitoring images of the monitoring scenario and / or monitoring videos of the monitoring scenario; When the voice information is obtained, converting the voice information into text information, extracting keywords from the text information, and obtaining the application requirements according to the keywords; When the text information is obtained, extracting keywords from the text information, and obtaining the application requirements according to the keywords; When the monitoring image and / or the monitoring video are obtained, obtaining the application requirements according to the monitoring image and / or the monitoring video.

[0050] It is easy to understand that the application requirements analyzed only by combining the monitoring image or the monitoring video information may not be accurate. For example: only the monitoring scenario information can be analyzed from the monitoring image, and the monitoring object information cannot be obtained; to simplify the process, the monitoring object information, the target field of view, and the target ranging range and other information can be preset according to the monitoring scenario information first; when the monitoring scenario information is obtained based on the monitoring image / monitoring video, the monitoring object information, the target field of view, and the target ranging range are obtained by matching the preset information.

[0051] Preferably, in order to obtain more accurate application requirements, other information input by the operation terminal (such as voice information and text information) can also be superimposed on the basis of the monitoring image / monitoring video to obtain accurate monitoring object information, target field of view, and target ranging range.

[0052] In step S2 of the lens configuration method provided in this embodiment, obtaining the lens ranging data set includes: The multi-camera is configured with a lens of a preset focal length, and the multi-camera respectively acquires the first images of the monitoring object at different distances; Inputting the first image into a preset target detection model to obtain the target recognition rate of the monitoring object in the first image; Obtain the first distance range corresponding to the first image whose target recognition rate is greater than the first preset value, and set the first distance range as the effective ranging range.

[0053] Specifically, the above multi-camera respectively collects the first images of the monitoring object at different distances. Specifically, the multi-camera focuses on infinity and respectively collects the first images of the monitoring object at different distances to ensure the accuracy and reliability of the lens ranging data set.

[0054] As an example, the first distance range can be obtained through the following operations: A lens with a preset focal length can be configured on the multi-camera, and the multi-camera is controlled to focus on infinity; gradually increase the distance between the multi-camera and the monitoring target, and collect the first images of the monitoring object at different distances until the target recognition rate of the first image meets the first preset value. At this time, the distance corresponding to the first image is used as the minimum recognition distance min1; continue to increase the distance between the multi-camera and the monitoring target, and collect the first images of the monitoring object at different distances until the target recognition rate of the first image does not meet the first preset value. At this time, the distance corresponding to the first image is used as the maximum recognition distance max1, then the first distance range is [min1, max1].

[0055] In this embodiment, when the multi-camera has a low requirement for ranging accuracy, the effective ranging range can be set according to the first distance range.

[0056] When the multi-camera has a high requirement for ranging accuracy, obtaining the lens ranging data set further includes: Set a number of test points according to the first distance range, and the distances between the number of test points and the monitoring object are not equal; The multi-camera respectively collects the second images of the monitoring object at the number of test points; Input the second image into the ranging accuracy model to obtain the ranging accuracy of the monitoring object in the second image; Obtain the second distance range corresponding to the second image whose ranging accuracy is greater than the second preset value, and update the effective ranging range according to the second distance range.

[0057] In this embodiment, point selection ranging can be performed according to the first distance range, and point selection ranging is performed near the two extreme points of the existing first distance range to select a second distance range with high ranging accuracy, and the effective ranging range is updated according to the second distance range to use the second distance range as the effective ranging range.

[0058] As an example, the second distance range can be obtained through the following operations: Set a number of test points according to the minimum recognition distance min1 and the maximum recognition distance max1. Among them, the distances between the number of test points set according to the minimum recognition distance min1 and the monitoring object gradually increase relative to the minimum recognition distance min1 until the ranging accuracy of the nearby test points can meet the second preset value. At this time, the distance between the nearby selected point and the monitoring object is used as the minimum ranging distance min2; the distances between the number of test points set according to the maximum recognition distance max1 and the monitoring object gradually increase relative to the maximum recognition distance max1 until the ranging accuracy of the distant test points can meet the second preset value. At this time, the distance between the distant selected point and the monitoring object is used as the maximum ranging distance max2, and the second distance range is [min2, max2].

[0059] In summary, the lens configuration method provided by the present invention can configure the lenses of a multi-camera based on application requirements, ensure that the lens performance of the multi-camera is fully utilized, and this lens configuration method can enable the multi-camera to adapt to different application scenarios and improve ranging accuracy.
