The Intel RealSense D415 is a precision‑focused stereo depth camera built around the D415 module and Vision Processor D4. Where the D435 prioritises wide coverage, the D415 prioritises depth quality per degree of field of view — its narrower 65° × 40° depth FOV concentrates every pixel on a smaller capture volume, yielding higher depth resolution and lower noise for precision 3D scanning tasks. It captures depth at up to 1280 × 720 / 90 fps, pairs it with a dedicated 2 MP RGB camera (1920 × 1080 @ 30 fps), and draws power from a single USB‑C 3.1 Gen1 cable. The D415 is powered by the open‑source librealsense SDK 2.0 with full ROS / ROS 2 support — the ideal entry point into the RealSense ecosystem for high‑accuracy 3D capture workflows. Features Standard FOV for Maximum Depth Quality — 65° × 40° depth FOV delivers the highest depth‑quality‑per‑degree in the D400 series, making it the preferred choice for precision 3D scanning, object digitisation, and volumetric capture where data density matters more than scene coverage. Active Stereo Vision with D415 Module — Coded‑IR dot projector + stereo imagers compute depth reliably across textured and semi‑textureless indoor surfaces. 55 mm Stereo Baseline — Wider baseline than the D435 (50 mm) provides better depth accuracy at mid‑range distances, especially in the D415's sweet spot of 0.5–3 m. Rolling Shutter Depth + RGB — Both depth and colour use rolling‑shutter sensors, optimised for stationary or slow‑moving capture workflows where the camera or subject does not move rapidly. Dedicated 2 MP RGB Camera — Independent 1920 × 1080 @ 30 fps colour sensor with 69° × 42° FOV for texture‑mapping and colour‑point‑cloud generation, separate from the depth module. Sub‑centimetre Depth Accuracy — < 2% error at 2 m; Min‑Z starts at ~45 cm at full 1280 × 720 resolution, ideal for desktop‑scale and mid‑range 3D capture. 1280 × 720 @ 90 fps Depth — High‑resolution, high‑frame‑rate depth streams produce dense, low‑noise point clouds suitable for post‑processing and mesh generation. No IMU — No gyroscope/accelerometer; choose the D435i if 6‑axis inertial data is required alongside depth. Vision Processor D4 — On‑board ASIC handles all stereo matching and ISP processing, reducing host CPU load and USB bandwidth requirements. USB‑C Single‑Cable Power & Data — Bus‑powered via USB‑C 3.1 Gen1; ~2.5 W typical power draw, no external power adapter required. Slim Profile & Dual Mounting — 99 mm × 20 mm × 23 mm slim enclosure with 1/4‑20 UNC tripod thread and 2× M3 screw holes for flexible robot‑frame or arm attachment. Open SDK & ROS Support — Cross‑platform librealsense 2.0 (Python, C++, C#, Java, MATLAB) and realsense‑ros / realsense2‑ros packages for rapid prototyping and production deployment.

Packing List Description Quantity Intel RealSense D415 Depth Camera × 1 Stand × 1 USB-C Cable × 1 FAQ 1. How does the D415 differ from the D435? The D415 and D435 share the same Vision Processor D4 and USB‑C interface, but differ in three key ways: (1) FOV — the D415 has a narrower 65° × 40° depth FOV vs the D435's wide 87° × 58°; (2) Baseline — D415 uses a ~55 mm baseline vs D435's 50 mm; (3) Sensor type — D415 uses rolling‑shutter sensors on both depth and RGB, while D435 uses global shutter on depth for motion capture. Choose the D415 for precision 3D scanning and the D435 for wide‑coverage robotics and fast‑moving capture. 2. What is the ideal depth range of the D415? The D415 performs best in the 0.5 m – 3 m range. The Min‑Z (closest usable depth) is ~45 cm at full 1280 × 720 resolution. The D415 is not designed for ultra‑close work — for 7–50 cm precision tasks, choose the D405 with its dedicated short‑range D401 module. 3. Does the D415 work outdoors? The D415 can be used outdoors in shaded or low‑ambient‑light conditions, but like all active‑stereo cameras, direct sunlight saturates the IR projector and degrades depth quality. For permanent outdoor installations, consider sun‑shading enclosures or switch to a LiDAR sensor like the Intel RealSense L515 for sunlight‑immune scanning. 4. Why does the D415 use a narrower FOV than the D435? The D415's 65° × 40° standard FOV concentrates the D415 module's depth pixels on a smaller field, increasing depth quality per degree of scene coverage. This makes it superior for precision scanning tasks where you need the highest possible depth resolution and lowest noise — not the widest scene coverage. If your robot needs to see a large room, the D435's 87° FOV is the better choice. 5. Can the D415 be used with ROS or ROS 2? Yes. The official realsense‑ros and realsense2‑ros packages expose depth, colour, and IMU (D435i) topics as standard sensor messages. Ubuntu 18.04 / 20.04 / 22.04 are officially supported. Pre‑built Docker images and snaps are also available for quick setup. 6. Can the D415 be powered over USB only? Yes. The D415 is bus‑powered via the USB‑C 3.1 Gen1 connection. Typical power draw is ~2.5 W. A USB‑C port on a desktop PC or a powered USB hub is sufficient. No external power adapter is required. 7. Can multiple D415 cameras be used simultaneously? Yes. Multiple D415 units can operate in the same space without mutual interference from their IR projectors. This enables multi‑camera rigs for wider coverage, volumetric capture, or stereo‑pair setups. Software synchronisation (timestamp matching) through the librealsense API is supported for frame‑aligned recording. 8. How does the D415 compare to the newer D455 series? The D455 series features the newer D450 stereo module with a longer 95 mm baseline, extended range (up to ~20 m), global‑shutter RGB, and optional features (IR Pass Filter on D455F, IP65 on D456). The D415 remains the preferred choice for precision 3D scanning at close to mid‑range when budget is a constraint and the narrower 65° FOV is acceptable. 9. Does the D415 support hardware synchronisation? The D415 supports software synchronisation (timestamp matching through librealsense). For precise hardware‑sync use cases requiring frame‑synchronised multi‑camera setups, consider the D455 series which includes a dedicated sync cable header. 10. What programming languages and frameworks support the D415? The librealsense 2.0 SDK provides official bindings for Python, C++, C#, Java, and MATLAB. Community bindings also exist for Node.js, Unity (RealSense Unity package), Unreal Engine, and ROS/ROS 2. The Intel RealSense Viewer app gives you a zero‑code GUI for stream preview, recording, and device configuration.
