Parameter Tunning Guide

This guide will walk through some rules of thumb when it comes to adjusting parameters to get better detection.

Not detection all objects

  • Increase the search detail. This will increase the number of computed scene features

  • Decrease acceptance threshold. This lowers the acceptance threshold of the score filter, keeping poses with lower scores

False positive

  • Reduce downsample strength. This makes the downsample voxel size smaller, preserving more detail in the scene. Reducing downsample strength can also improve poses that are badly oriented.

Model parameters

  • Adjust model feature detail. Increasing model feature detail will increase the amount of model features calculated, making it more likely to accurately find the object in the scene

  • Adjust model downsample strength. Reducing downsample strength can remove false positives
