Problems solved by technology
like Figure 7 As shown, we assume that the target can only be observed in the three portrait bounding boxes, and then estimate the scale of the figure in the picture. This situation will often happen, because the position of the bounding box of the portrait is difficult to determine, different visual detection Technology and external motion platforms will cause strong fluctuations and randomness in the actual shooting image effect, we need to deal with these situations

Embodiment Construction
[0033] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] figure 1 It is a schematic flowchart of the first unmanned shooting automatic zoom method provided by the embodiment of the present invention, as shown in figure 1 As shown, the automatic zoom method for unmanned shooting includes step S110-step S170, specifically as follows:
[0035] Step S110, receiving a zoom control instruction input by a user.
[0036] Wherein, the receiving the zoom control instruction input by the user includes: receiving the zoom control instruction input by the user through the mobile terminal APP or receiving the zoom control instruction input by the user through gesture recognition. For example, the user can input a bust zoom control command, a bust zoom control c...

The invention discloses an unmanned shooting automatic zoom method and system, an unmanned camera and a storage medium, comprising the following steps: receiving a zoom control command input by a user; detecting a target portrait in an image captured by the camera in real time, and obtaining the target of the target portrait Portrait bounding box; obtain the scale of the target portrait bounding box based on the deep convolutional neural network; calculate the scale error between the scale of the target portrait bounding box and the preset command scale in the zoom control command; judge whether the scale error is within the preset error range, If not, control the zoom motor of the camera to rotate according to the scale error; if so, control the zoom motor of the camera to stop rotating to complete automatic zooming. The present invention controls the rotation of the zoom motor of the camera by obtaining the scale of the bounding box of the target portrait and cooperates with different preset command scales, and can complete the automatic zoom shooting of the shooting target without manual direct operation of the camera, improving the shooting effect and meeting the needs of users.
Description
technical field [0001] The invention relates to the technical field of photography, in particular to an automatic zooming method and system for unmanned photography, an unmanned camera and a storage medium. Background technique [0002] The existing camera work requires someone to directly participate in the operation and control. The user directly holds the shooting terminal to shoot, or borrows the shooting platform to control. Among them, the image data collected by the shooting terminal is used to select the bounding box (bounding-box) The biggest one is the subject of shooting, and its essence is also controlled by the user, choosing the focal length for shooting and then shooting. If the user wants to take pictures with different scales, manual focus is required. For example, the user is currently taking a full-body photo. When he wants to take a half-length photo, he can only adjust the focal length of the camera terminal to take pictures. The operation is cumbersome ...
