Referring to fig. 1, in an embodiment of the present invention, a photographing control method is provided, including:
step 101: detecting the length of a selfie stick through a photoelectric displacement sensor or a laser distance sensor arranged in a stick body of the selfie stick;
step 102: determining a target distance between a shooting object and a terminal according to the length of the self-timer rod;

The self-timer rod can detect the length of the self-timer rod through a photoelectric displacement sensor or a laser distance sensor arranged in a rod body of the self-timer rod, the terminal can acquire the length of the self-timer rod through the communication connection, and the target distance between a shooting object (such as a human face) and the terminal is determined according to the length of the self-timer rod. For example, if the length of the selfie stick is L and the empirical length of the user's arm is s, the target distance may be L + s. The experience length of the arm of the user can be used as a preset basic length, and the experience length is preset by the user according to the length of the arm of the user and is stored in the terminal. After the target distance is determined, the terminal can control the light supplement lamp to adjust light supplement parameters, such as light supplement power, light supplement angle and the like, according to the target distance so as to obtain an ideal light supplement effect.
In one embodiment, the detecting a length of the selfie stick by a photoelectric displacement sensor disposed in a body of the selfie stick includes:
detecting the displacement of an inner rod piece of each level of nested telescopic structures of the selfie stick relative to an outer rod piece through a photoelectric displacement sensor;
and calculating the length of the self-timer rod according to the displacement of the inner rod relative to the outer rod of each level of the nested telescopic structure.
Referring to fig. 2, in the present embodiment, a selfie stick 100 using the photographing control method is provided, which includes a stick body 10, where the stick body 10 includes at least two stick members 11 nested in sequence, and any two adjacent stick members 11 form a first-level nested telescopic structure 110.
Each stage of the nested telescopic structure 110 includes an inner rod 111, an outer rod 112 and a photoelectric displacement sensor 113, the outer rod 112 of each stage of the nested telescopic structure 110 is used as the inner rod of the previous stage of the nested telescopic structure, and the inner rod 111 of each stage of the nested telescopic structure 110 is used as the outer rod of the next stage of the nested telescopic structure.
The inner rod 111 comprises a nested end 1111, the outer rod 112 comprises a nested end 1121, the nested end 1111 of the inner rod is slidably nested in the outer rod 112 through the nested end 1121, and the photoelectric displacement sensor 113 is disposed on the outer wall of the nested end 1111 of the inner rod 111 for detecting the displacement of the inner rod 111 relative to the outer rod 112 to calculate the length of the selfie stick 100 according to the displacement. It can be understood that when the optical electric displacement sensor 113 is arranged, a groove with a corresponding size may be arranged on the outer wall of the nested end 1111 of the inner rod 111, and the optical electric displacement sensor 113 is accommodated in the groove, so as to ensure good smoothness of the outer wall of the inner rod 111.
During the sliding extension or contraction of the inner rod 111 relative to the outer rod 112, the photoelectric displacement sensor 113 on the outer wall of the nested end 1111 of the inner rod 111 emits a set of detection light to illuminate the inner wall of the outer rod 112. When the inner rod 111 slides and stretches relative to the outer rod 112, the photoelectric displacement sensor 113 continuously acquires images of the inner wall of the outer rod 112, and calculates the displacement of the inner rod 111 relative to the outer rod 112 by analyzing the change of the position of the feature point on the images. It is understood that, in order to improve the accuracy of the displacement of the inner rod 111 relative to the outer rod 112 detected by the photoelectric displacement sensor 113, the inner wall of the outer rod 112 may be provided with a rough or textured surface. It is understood that the photoelectric displacement sensor 113 may also be disposed on the inner wall of the nesting end 1121 of the outer rod 112, and correspondingly, the outer wall of the inner rod 111 is disposed as a rough or textured surface.
Each stage of the nested telescopic structure 110 further includes an optical coupler 114, where the optical coupler 114 is disposed on an inner wall of one end of the outer rod 112 opposite to the nesting end 1121, and is configured to detect an absolute displacement of the inner rod 111 relative to the outer rod 112 at a preset position, and trigger the photoelectric displacement sensor 113 to correct a displacement detection error according to the absolute displacement.
Specifically, the optical coupler 114 includes an optical detection signal emitter 1141 and an optical detection signal receiver 1142, and the optical detection signal emitter 1141 and the optical detection signal receiver 1142 are disposed on an inner wall of one end of the outer rod 112 opposite to the nesting end 1121. The optical detection signal transmitter 1141 is configured to transmit light, and the optical detection signal receiver 1142 is configured to receive the light transmitted by the optical detection signal transmitter 1141. When the optical detection signal receiver 1142 can normally receive the light emitted from the optical detection signal emitter 1141, the optical coupler 114 outputs a first coupling state, and when the optical detection signal receiver 1142 cannot receive the light emitted from the optical detection signal emitter 1141 (for example, when the light is blocked by the inner rod 111), the optical coupler 114 outputs a second coupling state. The preset position is a position where the light emitted by the optical detection signal emitter 1141 is just shielded by the nested end 1111 of the inner rod 111, that is, a position of the inner rod 111 at the moment when the output of the optical coupler 114 is switched from the first coupling state to the second coupling state.
It can be understood that, since the position of the optical coupler 114 on the inner wall of the outer rod 112 is known, and the lengths of the inner rod 111 and the outer rod 112 are known, the absolute displacement of the inner rod 111 relative to the outer rod 112 is also determined when the inner rod 111 is slidably extended and retracted to block the light emitted from the optical detection signal emitter 1141. Since the displacement detected by the photoelectric displacement sensor 113 inevitably has an error during the sliding and expansion of the inner rod 111 relative to the outer rod 112, the error is accumulated as the expansion and contraction times increase. Therefore, when the output of the optical coupler 114 is switched from the first coupling state to the second coupling state, the absolute displacement of the inner rod 111 with respect to the outer rod 112 can be set as the output of the photoelectric displacement sensor 113, thereby achieving correction of the error of the photoelectric displacement sensor 113.
The selfie stick 100 further comprises a transmitter 115, a fixing frame 116, a first light supplement lamp 117 and a second light supplement lamp 118, wherein the fixing frame 116 is connected with one end of the stick body 10 and used for fixing the terminal 300.

The first rotation mechanism 1171 and the second rotation mechanism 1181 may include stepping motors.

It is understood that the transmitter 115 can also directly transmit the position detected by the photoelectric displacement sensor 113 to the terminal 300, and the terminal 300 calculates the length of the selfie stick 100 according to the displacement. The transmitter 115 may be a bluetooth or Wi-Fi probe transmitter, and is configured to establish a communication connection with the terminal 300. The terminal 300 may be a smart phone, a digital camera, or the like. The light supplement parameter may be a light supplement power, a light supplement angle, and the like.

The inner rod 211 comprises a nested end 2111, the outer rod 212 comprises a nesting end 2121, and the nested end 2111 of the inner rod is slidably nested within the outer rod 212 by the nesting end 2121. The inner rod 211 and the outer rod 212 of each stage of the nested telescoping structures 210 can be relatively stretched or contracted, thereby changing the length of each stage of the nested telescoping structures 210. During the sliding extension or contraction of the inner rod 211 relative to the outer rod 212, the probe signal emitter 221 emits a probe signal, which passes through the inner cavity of the sequentially nested hollow rods 21 and is received by the probe signal receiver 222, and the length of the selfie stick 200 can be calculated by calculating the time difference between the emission and the reception of the probe signal and combining the propagation velocity of the probe signal in the air. For example, assuming that the time difference between the transmission and reception of the probe signal is Δ t, the propagation speed of the probe signal in the air is c, the length of the self-timer stick is L, the calculation formula of the length L of the self-timer stick can be expressed as: l ═ Δ t × c. In this embodiment, the distance measuring sensor 220 is a laser distance measuring sensor, and the detection signal is a laser beam. It can be understood that, in order to reduce the reflection of the detection signal during the propagation of the inner cavities of the sequentially nested hollow bars 21 and improve the accuracy of the length measurement of the selfie stick 200, a light absorption paint layer 2101 may be further disposed on the inner wall of the hollow bars 21.

After the terminal obtains the target distance according to the length calculation of the self-timer rod, the corresponding light supplement power can be obtained according to the target distance, and then the light supplement lamp is controlled according to the light supplement power to adjust the intensity of light supplement light. It can be understood that the adjustment of the fill-in light power may be linear adjustment or non-linear adjustment; the light supplement power may be adjusted continuously, that is, the light supplement power is smoothly and continuously adjusted according to the change of the target distance, or may be adjusted discretely, that is, the target distance is divided into a plurality of segments, and each segment corresponds to one light supplement power.
