Abstract

Disclosed are a shooting calibration method, a system, an equipment and a storage medium. The shooting calibration method is applied to a shooting calibration system which includes an electronic equipment and a wearable equipment. The shooting calibration method includes: shooting, by the electronic equipment, a first target image, and sending the first target image to the wearable equipment; receiving, by the wearable equipment, the first target image sent by the electronic equipment; and in response to that the first target image does not overlap with a second target image observed through the wearable equipment, adjusting an image size parameter of the first target image, and returning to execute a step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining a target adjustment parameter.

First claim

What is claimed is:

1 . A shooting calibration method, applied to a shooting calibration system, wherein the shooting calibration system comprises an electronic equipment and a wearable equipment, and the electronic equipment is communicated with the wearable equipment; the shooting calibration method comprises:
shooting, by the electronic equipment, a first target image, and sending the first target image to the wearable equipment; receiving, by the wearable equipment, the first target image sent by the electronic equipment; and in response to that the first target image does not overlap with a second target image observed through the wearable equipment, adjusting an image size parameter of the first target image, and returning to execute a step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining a target adjustment parameter.

2 . The shooting calibration method according to claim 1 , wherein a shooting angle corresponding to a camera of the electronic equipment is consistent with a shooting angle corresponding to the wearable equipment, and a shooting sight corresponding to the camera of the electronic equipment is consistent with a shooting sight corresponding to the wearable equipment.

3 . The shooting calibration method according to claim 1 , wherein the shooting, by the electronic equipment, the first target image, and sending the first target image to the wearable equipment comprises:
shooting, by a camera of the electronic equipment, a preset target, to obtain a target image; and removing background of the target image to obtain the first target image, and transmitting the first target image to the wearable equipment.

4 . The shooting calibration method according to claim 1 , wherein after the receiving, by the wearable equipment, the first target image sent by the electronic equipment, the shooting calibration method further comprises:
projecting the first target image on a lens screen of the wearable equipment; determining a offset between the second target image and the first target image; and performing image offset compensation on the first target image based on the offset, to determine whether the second target image overlaps with the first target image after the offset compensation.

5 . The shooting calibration method according to claim 1 , wherein the in response to that the first target image does not overlap with the second target image observed through the wearable equipment, adjusting the image size parameter of the first target image, and returning to execute the step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining the target adjustment parameter comprises:
in response to that a size of the first target image is smaller than a size of the second target image, increasing a image size parameter of the first target image to obtain the first target image after parameter adjustment; and returning to execute the step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and configuring an image size parameter corresponding to an overlapped image as the target adjustment parameter.

6 . The shooting calibration method according to claim 1 , wherein the in response to that the first target image does not overlap with the second target image observed through the wearable equipment, adjusting the image size parameter of the first target image, and returning to execute the step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining the target adjustment parameter comprises:
in response to that a size of the first target image is larger than a size of the second target image, reducing the image size parameter of the first target image to obtain the first target image after parameter adjustment; and returning to execute the step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and configuring an image size parameter corresponding to an overlapped image as the target adjustment parameter.

7 . The shooting calibration method according to claim 1 , wherein after the in response to that the first target image does not overlap with the second target image observed through the wearable equipment, adjusting the image size parameter of the first target image, and returning to execute the step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining the target adjustment parameter, the shooting calibration method further comprises:
calibrating a camera of the electronic equipment based on the target adjustment parameter; sending an environment virtual image to a calibrated electronic equipment based on the environment virtual image shot by the wearable equipment in a virtual space; and based on a target image shot through the calibrated electronic equipment and the environment virtual image sent by the wearable equipment, superimposing the environment virtual image and the target image to obtain a composite image.

8 . A shooting calibration system, comprising:
an electronic equipment; and a wearable equipment communicated with the wearable equipment; a sending module, configured to obtain a first target image shot by the electronic equipment, and send the first target image to the wearable equipment; a receiving module, configured to receive the first target image sent by the electronic equipment through the wearable equipment; and an adjustment module, configured to adjust an image size parameter of the first target image in response to that the first target image does not overlap with a second target image observed through the wearable equipment, and return to execute a step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtain a target adjustment parameter.

9 . An electronic equipment, comprising a camera, a memory, a processor, and a shooting calibration program stored in the memory, wherein when the shooting calibration program is executed by the processor, the shooting calibration method according to claim 1 is implemented.

10 . A storage medium, wherein the storage medium is a non-transitory computer-readable storage medium, a shooting calibration program is stored on the non-transitory computer-readable storage medium, and when the shooting calibration program is executed by a processor, the shooting calibration method according to claim 1 is implemented.
