Embodiment 1

[0035] Such as figure 1 As shown, the flow chart of the monocular rotating panoramic camera light metering method provided by Embodiment 1 of the present invention includes steps:

[0036] Step 1: Start metering, rotate the camera to the initial position, stay for a time of t, the camera performs automatic exposure, after the exposure is over, obtain the exposure parameters of the position; the exposure parameters include exposure time, gain and aperture;

[0037] Step 2: Control the camera to rotate to the i-th (1≤i≤N) longitude position, the dwell time is t, the camera performs automatic exposure, after the exposure is over, obtain the exposure parameters of this position, and obtain N groups for N longitude positions in total Exposure parameters;

[0038] Step 3: Fuse N+1 groups of exposure parameter values ​​to obtain the best exposure parameters, the method is as follows:

[0039] Step 3.1: Set the aperture value unchanged;

[0040] Step 3.2: Calculate the maximum and ...

Embodiment 2

[0046] Embodiment 2 of the present invention provides a monocular rotating panoramic camera light metering system, including:

[0047] The initial position exposure parameter acquisition module: used to obtain the exposure parameters of the camera rotated to the initial position, the camera rotates to the initial position, the dwell time is t, the camera performs automatic exposure, and after the exposure, obtains the exposure parameters of the position; the dwell time t must be greater than or equal to the time when the camera's automatic exposure is completed;

[0048] N longitude position exposure parameter acquisition module: used to obtain N sets of exposure parameters when the camera rotates to N longitude positions, the camera rotates to the i-th (1≤i≤N) longitude position, the dwell time is t, and the camera performs automatic exposure , after the exposure is over, obtain the exposure parameters of this position, and obtain N sets of exposure parameters for N longitude...

Embodiment 3

[0053]Embodiment 3 of the present invention also provides a computer-readable storage medium. The computer-readable storage medium stores a computer program. When the computer program is executed by a processor, the monocular rotating panorama provided by Embodiment 1 of the present invention is realized. Steps in camera metering method.

Abstract

The invention discloses a monocular rotary panorama camera photometry method and system, and a portable terminal. The method includes: when the light is measured, enabling the camera to automaticallyexpose at the initial position, and obtaining exposure parameters; and controlling the camera to rotate to a plurality of longitude positions, obtaining exposure parameters of the camera at the current longitude position after the camera exposes stably at the current longitude position, fusing the plurality of groups of exposure parameters to obtain a group of optimal exposure parameters, and controlling the camera to collect images at the plurality of longitude positions according to the optimal exposure parameters. According to the method, the problem of light and shade difference caused byindependent exposure among multiple groups of images can be solved, the original image with consistent exposure is obtained, and later splicing is facilitated to obtain the seamless panoramic image.

Description

technical field [0001] The invention relates to the technical field of panoramic camera light metering, in particular to a monocular rotating panoramic camera light metering method, system, and portable terminal. Background technique [0002] Panoramic images can record 360-degree space information, and are well received in space display applications. With the panoramic player, viewers can watch the captured space images by turning their bodies or dragging the screen, such as houses, car interiors or It is a hotel environment display, etc., with a real look and feel. Since the panorama image is stitched from multiple pictures, when the exposures of the multiple pictures are inconsistent, the stitched panorama image will show obvious differences in light and dark, which will make the picture appear fragmented and affect the viewing experience of the viewer. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provide...
