Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 It is a flow chart of the camera rotation angle measurement method in an embodiment of the present invention, such as figure 1 Said, the method includes the following steps.

[0035] Step 101, setting a first passing line and a second passing line at a designated position on one side of the reference line of the test paper, and setting a third passing line and a fourth passing line at a designated position on the other side of the reference line of the test paper.

[0036] Step 102 , fix the camera to be tested at a specified distance from the test paper, and set the connecting line between the imaging center of the camera to be tested and a point on the reference line of the test paper to be perpendicular to the plane...

Abstract

The invention discloses a method and system for measuring the rotation angle of a camera. The method includes the steps that a first qualified line, a second qualified line, a third qualified line and a fourth qualified line are arranged on a datum line of a piece of testing paper; the camera to be measured is fixed at a designated position, and the imaging center of the camera to be measured is arranged to align to the center of the datum line of the testing paper; when the camera to be measured is rotated to the maximum angle towards one side, a first image of the testing paper is collected; when the camera to be measured is rotated to the maximum angle towards the other side, a second image of the testing paper is collected; whether the center line of the first image is located between the first qualified line and the second qualified line on the first image is judged, and whether the center line of the second image is located between the third qualified line and the fourth qualified line on the second image is judged; if yes, the rotation angle of the camera to be measured is within the designated angle range. According to the technical scheme, the problems that an existing method for measuring the rotation angle of the camera is complex in operation and low in efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of camera production, in particular to a method and system for measuring the rotation angle of a camera. Background technique [0002] With the increasing maturity of camera technology, more and more camera products appear in daily life. There are many types of cameras on the market, including retractable and rotatable. In the face of various styles of cameras, the determination of the rotation angle of the camera product during the production process has become a very important and difficult to measure problem. [0003] Traditional testing methods often use custom-made fixtures to determine whether the rotation angle is within the defined range. This method will not only cause large errors in the rotation angle of the test, but also cumbersome operations will easily lead to low production efficiency. However, the method of using laser ranging technology to calculate the rotation angle has the first problem...
