Description
本发明涉及一种矫正摄像头平行度和距离的定位装置及其方法。The invention relates to a positioning device and a method for correcting parallelism and distance of a camera.
在摄像头的测量测绘领域中，在某些情况下需要保持摄像头对拍摄平面严格平行的情况，以测试摄像头的性能或摄像头扫描条码的性能。一般的方法是采用目测法主观地对摄像头的角度进行调试或利用度量尺的垂直角对摄像头进行矫正，但这些方法矫正的精度不高，使得测出的结果误差较大。如果采用比较高端复杂的工装模具对摄像头与拍摄平面保持严格平行的情况，则需要投入较多的成本因素。In the field of measurement and mapping of cameras, in some cases it is necessary to keep the camera strictly parallel to the shooting plane to test the performance of the camera or the performance of the camera scanning bar code. The general method is to use the visual method to subjectively adjust the angle of the camera or use the vertical angle of the scale to correct the camera. However, the accuracy of the correction is not high, and the error of the measured result is large. If a relatively high-end complex tooling die is used to keep the camera and the shooting plane strictly parallel, more cost factors are required.
另一方面，有些用于扫描、拍摄的数码产品的摄像头并不是规则的与外边框呈平行或垂直角度，这对保持摄像头与拍摄平面的平行度带来一定的难度。因此，针对上述问题是本发明研究的对象。On the other hand, some of the cameras used for scanning and shooting digital products are not regularly parallel or perpendicular to the outer frame, which makes it difficult to maintain the parallelism between the camera and the shooting plane. Therefore, the above problems are the object of research of the present invention.
