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...

Abstract

The invention discloses an unmanned shooting automatic zooming method and system, an unmanned camera and a storage medium. The unmanned shooting automatic zooming method comprises the following steps:receiving a zooming control instruction input by a user; Detecting a target portrait in the image shot by the camera in real time, and obtaining a target portrait boundary frame of the target portrait; obtaining the scale of a target portrait boundary frame based on the deep convolutional neural network; calculating a scale error between the scale of the target portrait boundary frame and a preset command scale in the zoom control instruction; Judging whether the scale error is within a preset error range, and if not, controlling a zoom motor of the camera to rotate according to the scale error; and if yes, controlling a zoom motor of the camera to stop rotating, and finishing automatic zoom. The zoom motor of the camera is controlled to rotate by acquiring the scale of the target portrait boundary frame and cooperating with different preset command scales, automatic zoom shooting of the shot target can be completed without directly operating the camera manually, the shooting effect is improved, and the user requirement is met.

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 ...
