iToF engineering prototype debugging: jitter reduced to 6 mm but straight walls still bend 12–14 cm

Reddit user /u/No_Quail6685 built a home RGB + iToF depth setup using a 320×240 epc660-class iToF engineering sample, a fixed Pi camera, and Ouster reference scans. After raising exposure from 500 to 2,000 µs, filtered jitter dropped from 65 to 6 mm and raw jitter from 85 to 28 mm, but straight walls still bend 12–14 cm, and three modulation frequencies report 4.14, 3.92, and 3.97 m for the same wall. The user says fitting a correction to one wall at about 4 m reduced plane RMS from 4.45 to 1.84 cm, but this is only a single wall and does not count as calibration across the full working range; raising exposure improved coverage while nearby objects saturate.
