Systems and methods for supporting image-guided procedures include an elongate device including a steerable distal end and a shape sensor located along a length of the elongate device and one or more processors coupled to the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. In some embodiments, an insertion depth of the elongate device is monitored. In some embodiments, the data collection event is detected when the insertion depth is beyond a threshold insertion depth, no change of the insertion depth is detected for longer than a threshold period of time, or the insertion depth is beyond a threshold retraction distance.
