Drilling tool joint pose and orientation estimation apparatus
The patent US12050266B2 describes an innovative apparatus designed to enhance operations on a drilling rig by integrating multiple imaging technologies. The apparatus includes a time of flight (TOF) camera, an optical camera, and a processor that connects these devices. The processor is tasked with receiving various signals from the TOF camera, which provide data on the stick-up height, pitch, and roll of a tool joint in a drill string during tripping operations. Additionally, the optical camera contributes signals related to the stick-up height and roll of the tool joint. By processing this data, the apparatus generates pose and orientation estimates, enabling a roughneck to move effectively in relation to the tool joint based on these estimates.
Further enhancing its capabilities, the apparatus can also incorporate a light detection and ranging (LIDAR) sensor, which provides additional measurements related to the stick-up height and pitch of the tool joint. The processor utilizes this information to refine the estimates and send instruction signals to the roughneck, guiding their movements towards the tool joint for operational engagement. The claims highlight the use of three-dimensional point clouds and two-dimensional image data to generate the necessary signals, ensuring accurate and efficient operation on the rig drill floor. This technology aims to improve safety and efficiency in drilling operations by providing precise measurements and actionable guidance to personnel.
