Embodiment 1

[0044] Embodiment 1 of the present invention provides a camera testing method, which is applied to a camera testing system built by a motor, a reference object fixed on the motor shaft, a camera, and related control software, wherein the reference of this embodiment The object can be a flat plane with preset text or image logos, and the reference object of this embodiment can also be a three-dimensional object, and the three-dimensional object has preset text or image logos, or has a specific structural form . Specifically, please refer to figure 1 The flow chart of the camera testing method provided by Embodiment 1 of the present invention is shown. This embodiment proposes a camera testing method, which includes:

[0045] S1. Control the power source to move at a preset speed, and drive the reference object to move synchronously.

[0046] In this embodiment, on the one hand, the preset control software is used to control the start of the power source, so that the power sou...

Embodiment 2

[0055] Based on the above embodiments, optionally, the reference object for displaying readable text is set on the power source. Wherein, the reference object may be a fixed cardboard perpendicular to the rotation axis of the motor at 90°, and the rotational movement of the cardboard will form a motion plane. Based on the above-mentioned imaging characteristics of the motion plane, the power source can convert the object speed of the camera use scene into the motion speed of the power source, thereby more conveniently simulating the use scene of the camera facing real motion.

[0056] In this example, please refer to figure 2 A test schematic diagram of the camera test method provided by Embodiment 2 of the present invention is shown. Among them, the global shutter camera module of model OV7251 is taken as an example for illustration. For the relevant parameters of the camera module, please refer to the following table.

Embodiment 3

[0065] Please refer to image 3 A schematic structural diagram of a camera testing device provided by Embodiment 3 of the present invention is shown. Based on the above-mentioned embodiments, the present invention also proposes a camera testing device, which includes a controller 10, a power source 20 electrically connected to the controller 10 and a camera 30 to be tested, rigid with the power source 20 A connected reference object 40; wherein, the controller 10 controls the power source 20 to move at a preset speed, and drives the reference object 40 to move synchronously; the controller 10 controls the camera 30 to be tested to acquire the The reference image of the reference object 40 in a stable motion state; if the controller 10 determines that the reference image meets the current imaging conditions, it determines that the imaging frame rate meets the preset frame rate conditions.

[0066] Optionally, the power source 20 includes a motor.

[0067] Optionally, the cont...

Abstract

The invention discloses a camera testing method, device and equipment and a computer readable storage medium, and the method comprises the steps: controlling a power source to move at a preset speed, and driving a reference object to move synchronously; controlling a to-be-tested camera to acquire a reference image of the reference object in a stable motion state according to an imaging frame rate of the to-be-tested camera; and if the reference image accords with the current imaging condition, determining that the imaging frame rate accords with a preset frame rate condition. A camera testing scheme which is simple in structure and clear in logic is achieved, full-amount or sampling feeding testing during camera feeding is avoided, and the production cost and the time cost are remarkably reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a camera testing method, device, equipment and computer-readable storage medium. Background technique [0002] In the prior art, with the intelligent development of equipment and the increasing demand of users for video recording, it is more and more common to configure cameras on various equipment. Generally, cameras can be divided into high-speed cameras and low-speed cameras. For some high-speed camera application scenarios, such as sports cameras or high-speed illegal capture, the cameras used need a high frame rate to capture high-frequency moving objects. Otherwise, there may be smear or blurred images in the imaging of moving objects. At present, the cameras shipped by the camera manufacturers not only support high-speed photography, but also are compatible with low-speed photography. For specific application scenarios, the corresponding configuration needs to ...
