Method and system for calibration of an indoor space

A calibration device comprising:

• a processor;
• and
• a memory storing a set of instructions, the instructions executable in the processor to:
• receive instructions to acquire spatial data in a predefined region in an indoor space, the indoor space divided into a grid of a plurality of polygonal tiles in a size-wise hierarchy and tessellated at each level of the size-wise hierarchy, wherein the instructions comprise information regarding a group of polygonal tiles from amongst the plurality of polygonal tiles in the predefined region to gather the spatial data for, the group of polygonal tiles selected at a hierarchical level in the size-wise hierarchy, and wherein the spatial data is to be gathered for the group of polygonal tiles along a substantially continuous path connecting the group of polygonal tiles to be traversed for gathering the spatial data;
• commence, in response to the instructions, acquisition of the spatial data along the substantially continuous path;
• and
• generate a feedback indicative of conformance, in real-time, to the substantially continuous path, wherein the acquisition of the spatial data along the substantially continuous path is adjustable by conforming to at least one the substantially continuous path in response to the feedback.
