More Information
Summary:The invention relates to a measurement subsystem and a measurement system. The measurement system is configured to determine a position of a specific GNSS antenna (15) or a retroreflector of a position measuring resource installed on a measurement rod (10). The measurement system comprises a camera module (30) and a control and assessment unit (12), wherein the camera module (30) is designed to be attached to the measurement rod (10) and comprises at least one camera for photographing an image. The control and assessment unit controls and executes the following function: when the control and assessment unit moves along a route passing through an environment, a series of images of the environment is photographed by utilizing the at least one camera, the SLAM assessment of a definition algorithm utilizing the series of images is executed, a reference point field is established, a posture of the photographed image is determined, and based on the determined posture, point cloud comprising a 3D position of a point
