In the present embodiment, a snapshot method is provided, and fig. 2 is a flowchart of the snapshot method according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring a target image acquired by the camera equipment;
step S204, when a target object is included in the target image, adjusting the image pickup apparatus to a target magnification based on the position information of the target object;
step S206, determining a target rotation angle range of the camera under the target magnification, wherein the dark corner is not included in the acquired image when the camera rotates in the target rotation angle range;

The camera device may analyze images captured by the camera to determine whether an object of interest, i.e., a target object, is present in the area monitored by the camera device. The target object may be a person, an article, a vehicle, or the like. When a target object appears in the target image, the image capturing apparatus may be adjusted to the target magnification according to the position information in the image where the target object is located, so that the target object may appear in the image at a predetermined ratio, where the predetermined ratio may be a ratio set in advance, for example, the target object may occupy 75% of the entire screen (this value is merely an exemplary illustration, and may also be 50%, 60%, 80%, and the like, which is not limited by the present invention). And determining a target rotation angle range of the camera equipment under the target magnification, wherein when the camera equipment rotates any angle in the target rotation range, no dark angle exists in an image acquired by the camera equipment.

The field angle of the lens is in a negative correlation with the focal length of the lens, and the focal length of the lens affects the imaging magnification, so that the field angles of the lens at different magnifications are different. Therefore, the ball machine equipment adopting the same lens shell can actually realize different rotation ranges without a dark angle under different magnifications of the lens.
In the above-described embodiment, after the target rotation angle range is determined, the target rotation angle of the image pickup apparatus may be determined according to the target rotation angle range. After the image pickup apparatus has rotated the target rotation angle, the target object is in the target field of view of the image pickup apparatus. Wherein the target field of view region may include a middle of a field of view of the image pickup apparatus. When the target object is in the target visual field region, the snapshot operation is performed, and therefore, the efficiency of the snapshot can be improved.
Optionally, the main body of the above steps may be a camera device, or other devices with similar processing capabilities, and may also be a machine integrated with at least an image acquisition device and a data processing device, where the image acquisition device may include a graphics acquisition module such as a camera, and the data processing device may include a terminal such as a computer, a mobile phone, and the like, but is not limited thereto.
According to the invention, the target image acquired by the camera equipment is acquired, under the condition that the target image comprises the target object, the camera equipment is adjusted to the target magnification based on the position information of the target object, the target rotation range of the camera equipment under the target magnification is determined, the target rotation angle of the camera equipment is determined according to the target rotation range, and the camera equipment is controlled to execute the snapshot operation after the target rotation angle is rotated. The target rotation range of the camera equipment is determined by the target magnification, namely the target rotation ranges corresponding to different magnifications, and the image acquired when the camera equipment rotates in the target rotation range does not include a vignetting, so that the camera equipment is controlled to rotate by the target rotation angle determined by the target rotation range, and the vignetting does not exist in the image captured by the camera equipment, therefore, the problem that the captured view range is small due to the fact that the vignetting does not exist in the captured image in the related technology can be solved, and the effect of expanding the captured view range under the condition that the vignetting does not exist in the image captured by the camera equipment is achieved.
In one exemplary embodiment, determining the target rotation angle range of the image pickup apparatus at the target magnification includes: acquiring a first rotation angle range and a first field angle of the image pickup device at a minimum magnification supported by the image pickup device; determining a second field angle of the image pickup device under the target magnification; determining the target rotation angle range based on the first rotation angle range, the first field of view, and the second field of view. In the present embodiment, the target rotation angle may include a horizontal rotation angle and a vertical rotation angle. In determining the target rotation angle, it may be determined by a first rotation angle range at a minimum magnification supported by the image pickup apparatus, a first angle of view of the image pickup apparatus at the minimum magnification, and a second angle of view of the image pickup apparatus at the target magnification.
In the above embodiment, the holder is dynamically limited according to the size of the field angle under the minimum magnification of the lens and the change of the field angle in the zooming process, so as to provide the largest possible field range for the equipment without a dark angle
In one exemplary embodiment, determining the target rotation angle range based on the first rotation angle range, the first field angle, and the second field angle includes: determining a difference in the second field of view and the first field of view; determining a first sum of the difference and a first minimum value within the first rotation angle range and a second sum of the difference and a first maximum value within the first rotation angle range to obtain a second rotation angle range; determining the second rotation angle range as the target rotation range. In this embodiment, the dynamic limiting schematic diagram of the image capturing apparatus at a small magnification is shown in fig. 3, where as shown in fig. 3, the focal length of the lens is small and the field angle is large at the small magnification. In the vertical direction of the holder, the rotatable angle range is [ -A, + A ]. The dynamic limiting schematic diagram of the image capturing apparatus at a large magnification can be seen in fig. 4, as shown in fig. 4, when the magnification is increased, the focal length of the lens is increased, and the field angle is decreased. In the vertical direction of the holder, the rotatable angle range is [ -B, + B ], and the same applies to the horizontal direction. The multiplying power increases, and the rotation range that cloud platform realized not having the vignetting also increases.
In the above embodiment, the angle of view data at the current magnification (the vertical angle of view ft2, corresponding to the second angle of view) can be acquired in real time during the device magnification variation process by recording the angle of view data at the minimum magnification (the vertical angle of view ft1, corresponding to the first angle of view described above) of the image pickup device and the rotation angle range t1 (corresponding to the first rotation angle range described above) under the precondition of no vignetting. The rotation angle range t2 (corresponding to the above target rotation angle range) under the current vignetting-free condition is obtained by calculation. Wherein t2 is t1+ (ft 2-ft 1).
In the above embodiment, based on the fundamental principle that the lens image has a vignetting, the maximum rotation angle of the pan/tilt head at different positioning capture magnifications is dynamically calculated based on the negative correlation relationship between the lens field angle and the lens focal length (image magnification) and on the basis of obtaining the data of the field angle at the minimum magnification of the lens and the data of the maximum rotation angle of the pan/tilt head at the minimum magnification, so as to achieve dynamic limiting.
In one exemplary embodiment, determining the target rotation angle of the image pickup apparatus based on the target rotation angle range includes: determining a to-be-rotated angle when the image pickup device is rotated to enable the target object to be in a target view field of the image pickup device; determining a target relation between the angle to be rotated and the target rotation angle range; determining the target rotation angle based on the target relationship. In this embodiment, after the target rotation angle range is determined, a to-be-rotated angle when the image pickup apparatus is rotated to a position where the target object is in the target view area of the image pickup apparatus may be determined, a target relationship between the to-be-rotated angle and the target rotation angle range may be determined, and the target rotation angle may be determined according to the target relationship. The method can judge the issued rotation angle data when issuing a rotation angle instruction to the holder according to the calculated real-time non-vignetting rotation range data, avoids the generation of the vignetting of the lens picture on the software level, and realizes the positioning snapshot with dynamic limit. The target view area may be a middle area of a view of the image pickup apparatus, or any area in the view of the image pickup apparatus, in which the image pickup apparatus can capture a complete target object.
In an exemplary embodiment, determining the target rotation angle based on the target relationship includes: determining the angle to be rotated as the target rotation angle under the condition that the target relation indicates that the angle to be rotated is within the target rotation angle range; and under the condition that the target relation indicates that the angle to be rotated is out of the target rotation angle range, determining the target rotation angle based on the angle to be rotated and the target rotation angle range including a second minimum value and a second maximum value. In the present embodiment, in the case where the angle to be rotated is in the target rotation angle range, the angle to be rotated is determined as the target rotation angle. And when the angle to be rotated is out of the target rotation angle range, determining the target rotation angle according to the maximum value and the minimum value in the angle to be rotated and the target rotation angle range.
In an exemplary embodiment, determining the target rotation angle based on the angle to be rotated and the target rotation angle range including the second minimum value and the second maximum value includes: determining the second minimum value as the target rotation angle when the angle to be rotated is smaller than the second minimum value; and determining the second maximum value as the target rotation angle under the condition that the angle to be rotated is larger than the second maximum value. In the present embodiment, when the angle to be rotated is smaller than the minimum value in the target rotation angle range, the minimum value of the target rotation angle range is determined as the target rotation angle. And when the angle to be rotated is larger than the maximum value of the target rotation angle range, determining the maximum value of the target rotation angle range as the target rotation angle.
In the above embodiment, the maximum rotation angle of the pan/tilt head at the current magnification can be calculated according to the positioning snapshot magnification, the positioning instruction issued to the pan/tilt head is judged, the limit of the pan/tilt head is controlled from the software level, and the physical structure loss caused by adopting the physical limit structure is avoided

In the foregoing embodiment, according to the characteristics that the field angle of the lens decreases with the increase of the focal length and the magnification of the image decreases with the decrease of the focal length, the pan-tilt rotation range without a vignetting angle at the magnification is calculated in real time by calculating the numerical value of the capture magnification in the positioning capture instruction, and the delivered pan-tilt rotation instruction is determined according to the calculated range, so as to realize automatic dynamic limiting. The method can calculate the maximum rotation angle of the cradle head capable of realizing no dark angle of the picture under the current multiplying power according to the multiplying power when the equipment is positioned and captured, and adjust the positioning instruction according to the angle to realize the positioning and capturing of the maximum monitoring visual field range; according to the field angle under the minimum magnification of the lens and the maximum rotation angle of the holder under the minimum magnification, the maximum rotation angles of the holder under different positioning magnifications are calculated on the software level, and the issued positioning rotation instruction is subjected to limit control, so that the stability is high, and the physical damage of the hardware structure of the holder can not be caused; the dynamic cradle head on the software layer is limited, the automatic limitation of the cradle head is realized according to the correlation between the field angle and the parameters such as the focal length of the lens and the like from the root cause of the dark angle, and the high precision of the limitation is ensured.
