Q1 multiple-choice · lighting Right lighting approach for 3D reconstruction capture?
Source: SP3D02 §1.
Explanation: Reconstruction needs consistent surface info across rotation; dramatic lighting creates inconsistencies. Boring lighting + great PBR materials in post = beautiful model.
Q2 true-false · calibration Calibration targets (color checker + scale reference) are optional for 3D reconstruction capture.
Source: SP3D02 §3.
Explanation: Calibration targets are non-negotiable. Without them, model has unknown scale + biased color. Capture wasted.
Q3 multiple-choice · angle-coverage Standard angle set for typical product capture?
Source: SP3D02 §2.
Explanation: Reconstruction needs overlapping coverage across product surface. Multiple elevation passes ensure top, sides, bottom of overhangs all captured.
Q4 scenario · recapture-signal Mid-capture, lighting flickers around frame 80 of 144.
Source: SP3D02 §6.
Explanation: Lighting flicker is stop-signal. Inconsistent capture = guaranteed reconstruction defect. Recapture is cheaper than iteration.
Q5 multiple-choice · background PhotoRobot’s standard background separation approach?
Source: SP3D02 §4.
Explanation: Freemask is PhotoRobot’s integrated approach. Depth cutout requires specialty hardware; chroma key adds spill issues.
Q6 multiple-choice · pre-shot-checklist Which is NOT part of the pre-shot checklist?
Source: SP3D02 §5.
Explanation: Pre-shot checklist covers equipment + product + lighting + camera + workflow + quality gate. Analytics tracking is delivery-side (SP3D04), not capture-side.
Q7 scenario · reflective-decision Capturing a chrome watch on PhotoRobot studio. Photogrammetry-only pipeline.
Source: SP3D02 §2.
Explanation: Reflective + photogrammetry-only = struggle. Three options, customer chooses; specialist makes recommendation explicit.
Q8 multiple-choice · handoff What does the reconstruction team / vendor receive in the handoff?
Source: SP3D02 §7.
Explanation: Reconstruction needs full coverage + raw images. Don’t pre-process; don’t filter; provide the full input set + context.
Q9 multiple-choice · lifestyle-vs-reconstruction Same product needs both 360° viewer AND 3D reconstruction outputs. What’s the right capture approach?
Source: SP3D02 §1.
Explanation: Reconstruction lighting is the harder constraint; viewer accepts it. Capture for the harder use case.
Q10 multiple-choice · image-count Approximate image count for a simple product on standard 3D capture?
Source: SP3D02 §2.
Explanation: Simple product = ~144 images. Complex product = 200-400. Hero automotive interior = 1000+. Storage + reconstruction time scales accordingly.
