Analyze the impact of sensor placement on an autonomous vehicle's ability to detect its environment.

Example answer

Choose sensor placement from the vehicle geometry, required tasks, range and operating conditions. There is no universally correct camera height or bumper spacing. Map fields of view and blind regions for near objects, distant targets, turns, slopes and occlusion by the vehicle itself or other road users.

Compare the actual camera, radar, LiDAR or ultrasonic devices against those requirements. Mounting affects vibration, thermal exposure, contamination, cleaning, protection and calibration stability. A position with broad nominal coverage may be obstructed by cargo, dirt, reflections or a structural component in practice.

Specify intrinsic, extrinsic and temporal calibration and how mounting changes are detected. Overlap can support fusion and diagnosis, but shared environmental, timing or power faults remain. A richer sensor suite does not automatically preserve performance in every weather condition.

Use simulations and controlled physical tests with measured reference geometry, then assess representative and difficult scenarios for the intended domain. Measure detection/estimation quality, data age and downstream behavior, including single and common-cause failures. Document unresolved blind regions and capability limits instead of claiming a modality is universally indispensable or sufficient.
