Method, apparatus, and system for selecting sensor systems for map feature accuracy and reliability specifications

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more programs,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• select at least one survey point that has a known physical location;
• initiate a plurality of passes to capture a plurality of images of the at least one survey point using a sensor system;
• for each pass of the plurality of passes, calculate an estimated location of the at least one survey point based on the plurality of images and calculate error data based on the estimated location and the known physical location;
• generate an error curve with respect to a number of the plurality of passes based on error data for said each pass;
• and
• provide an output indicating a target number of passes to meet an error specification based on the error curve.

A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

• selecting at least one survey point that has a known physical location;
• initiating a plurality of passes to capture a plurality of images of the at least one survey point using an image-based sensor system;
• for each pass of the plurality of passes, calculating an estimated location of the at least one survey point based on the plurality of images and calculating error data based on the estimated location and the known physical location;
• generating an error curve with respect to a number of the plurality of passes based on the error data for said each pass;
• and
• providing an output indicating a target number of passes to meet an error specification based on the error curve.
