Both extremes lead to point cloud distortions. For example, black PVC piping has both low reflectivity (black color) and highly specular surfaces, creating both voids and spikes in the point cloud (Image Set 4, Example c.) Targets that are black or very dark will absorb light and thus return the least amount of light creating voids or holes in the point cloud. Targets with high specular reflections can saturate pixels creating spikes in the point cloud that are closer in distance than their true position. Targets with these properties may not be suitable for ToF. \t<br \/>\n\t<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-2\"><strong>Targets with diffuse surfaces and high reflectivity work best for ToF (Image Set 4, Example a, b, d).<\/strong> These targets send enough light back to the ToF sensor without specular reflections. Some objects however, exhibit properties that are less than ideal but are still discernible within the scene. In these situations, it is possible to increase target details via changes in exposure time and gain, image accumulation, and filtering.<br \/>\n\t<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-3\">Determining the best exposure time maximizes usable depth data for both high- and low-reflectivity targets. <strong>The Helios2 camera models enables three discrete exposure time presets as well as high and normal gain settings.<\/strong> Longer exposure times and high gain should be used for scenes further from the camera, or when imaging objects with low reflectivity. Shorter exposure time and normal gain is used for scenes closer to the camera, or objects that appear over saturated.<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-4\">EXPOSURE TIME AND GAIN<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-5\">IMAGE ACCUMULATION<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-6\">The Helios2 processing pipeline is capable of accumulating multiple frames for improved depth calculations. This is helpful for targets that produce noisy data. With image accumulation, depth frames are averaged over a set number of frames, improving imaging results. It should be noted that the higher the number of frames accumulated, the slower the depth data generation, as more images must be captured to calculate the data.<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-7\">CONFIDENCE THRESHOLD<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-8\">Depth data confidence is based on a level of intensity for each point. If a returning signal is too weak, there is low confidence in the resulting depth data. Thresholding removes depth data with low intensity\/confidence, improving scene clarity.<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-9\">SPATIAL FILTERING<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-10\">Spatial filtering reduces noise by adjusting and averaging depth data differences between neighboring pixels\u2014smoothing out surfaces. Additionally, the Helios camera also uses edge-preservation in its spatial filtering, reducing noise in surfaces while maintaining object-edge sharpness.<br \/>\n<\/sr7-layer>\n\t\t\t\t\t\t\t<sr7-layer id=\"SR7_142_1-340-11\">The Helios2 processing pipeline is capable of accumulating multiple frames for improved depth calculations.
