Problems solved by technology

[0002] At present, single or multiple cameras can be used to measure spatial point coordinates. The cameras are generally mounted on a tripod. When calibrating and measuring, for a single camera, we need to move the camera multiple times to achieve multi-view acquisition of the target. For With multiple cameras, we need to move each camera so that the images collected by each camera include all target points, which is not convenient for us to operate and reduces work efficiency. In addition, the tripod is not stable enough. If it is accidentally touched, it will cause camera damage. destruction

Embodiment 1

[0032] Such as figure 1 As shown, the present embodiment provides a multi-degree-of-freedom motion shooting platform device, the platform device includes an up and down telescopic mechanism 1, a front and rear movement mechanism 2, a left and right movement mechanism 3 and a two-axis pan-tilt 4, and the two-axis pan-tilt 4 is arranged on The left and right movement mechanism 3 is used to install the camera 5 and control the rotation of the camera 5 around the yaw axis and the pitch axis. The front and rear movement mechanism 2 is arranged on the up and down telescopic mechanism 1. 1 is used to adjust the height of the front and rear movement mechanism, the front and rear movement mechanism 2 is used to control the left and right movement mechanism 3 to move forward and backward, and the left and right movement mechanism 3 is used to control the left and right movement of the two-axis pan-tilt 4.

[0033] In order to support the entire platform device stably, the multi-degree-o...

Embodiment 2

[0059] Such as Image 6 As shown, it is a schematic diagram of static point coordinate measurement realized by a single camera in this embodiment. When measuring static point coordinates, firstly, a marker point should be pasted on the measurement point, so that the later image processing software can easily extract the pixel coordinates of the marker point. , and then the operator uses the up and down telescopic mechanism 1 to adjust the height of the camera 5, and then uses the forward and backward movement mechanism 2, the left and right movement mechanism 3 and the two-axis platform 4 to make the camera 5 translate and rotate, and adjust the camera 5 to the best first shooting position. Adjust the focal length and image resolution of the camera 5 so that the marked points in the image are clearly visible, collect the image of the first shooting position, then adjust the pose of the camera 5 to the second shooting position, and continue to adjust the focal length and image r...

Abstract

The invention discloses a multi-freedom-degree movable shooting platform device and a spatial point coordinatemeasuring method. The multi-freedom-degree movable shooting platform device comprises a vertical extensible mechanism, a front-back moving mechanism, a left-right moving mechanism and a two-shaft holder, wherein the two-shaft holder is arranged on the left-right moving mechanism and used for installing a camera and controlling the camera to rotate around a heading shaft and a pitching shaft, the front-back moving mechanism is arranged on the vertical extensible mechanism, the left-right moving mechanism is arranged on the front-back moving mechanism, the vertical extensible mechanism is used for adjusting the height of the front-back moving mechanism, the front-back moving mechanism is used for controlling front-back movement of the left-right moving mechanism, and the left-right moving mechanism is used for controlling left-right movement of the two-shaft holder. The multi-freedom-degree movable shooting platform device integrates calibration and measurement, is convenient to operate and capable of saving effort and effectively improves the measurement efficiency and safety.

Description

technical field [0001] The invention relates to a shooting platform device, in particular to a multi-degree-of-freedom motion shooting platform device and a space point coordinate measurement method, belonging to the field of machine vision measurement. Background technique [0002] At present, single or multiple cameras can be used to measure spatial point coordinates. The cameras are generally mounted on a tripod. When calibrating and measuring, for a single camera, we need to move the camera multiple times to achieve multi-view acquisition of the target. For With multiple cameras, we need to move each camera so that the images collected by each camera include all target points, which is not convenient for us to operate and reduces work efficiency. In addition, the tripod is not stable enough. If it is accidentally touched, it will cause camera damage. destruction. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned de...
