Choosing the right depth camera for your vision project is critical, so let\u2019s look at some of the key similarities and differences between the two models.\n\nWhat\u2019s the same? Physically, the two depth cameras are about the same size (within millimeters). Both use the same vision processor to provide RGB-D data over USB 3, and they have the same maximum depth resolution of 1280 x 720. See the entire comparison chart at the end of the post for specific measurements.\n<h5>Two Main Differences<\/h5>\nThere are two main differences between the two models\u2014field of view (FOV) and shutter type.\n<h5>Field of View<\/h5>\nThe RealSense D415 depth camera has approximately a 70-degree field of view (FOV). The RealSense D435 depth camera has a wider FOV at approximately 90 degrees.\n<h5>Shutter Type<\/h5>\nSecond, the RealSense D415 depth camera has a rolling shutter while the RealSense D435 depth camera has a global shutter.\n\nThe wider FOV of the RealSense D435 depth camera makes it better for use cases like robotics and drones trying to navigate. The larger FOV results in more time to react to obstacles, plus the global shutter provides better performance if you\u2019re capturing high-speed motion by preventing blurring of the depth image or shooting in low-light situations.\n<h5>RealSense Module Differences<\/h5>\nAnother difference between the two depth cameras is the RealSense D415 depth camera is based on the RealSense D415 module. This means the imagers, emitters, and RGB are on one compute board, or stiffener, making calibration much easier.\n\nThe RealSense D435 camera is based on the RealSense D430 module with an attached, but separate, RGB camera. The depth algorithm is based on precise placements of sensors, so not having them fixed on the same stiffener may make calibration between depth and RGB problematic. However, users of previous-generation cameras said they really wanted the flexibility of choosing their own RGB cameras.\n<h5>Imager Differences and Accuracy<\/h5>\nAnother difference is the RealSense D415 depth camera uses two-megapixel imagers, while the RealSense D435 depth camera\u2019s imagers are one megapixel each.\n\nWhat does this mean in terms of the camera\u2019s performance? Because the FOV is larger for the RealSense D435 depth camera, you\u2019ll notice less granularity when looking at a specific portion of the image. Stereoscopic cameras take two images from the two sensors on the camera, which have slightly different points of view, and compare them. The shift between the same points in both images can be used to determine depth.\n\nThese pictures show a magnified and exaggerated view of what each camera\u2019s sensors see.\n\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-376\" src=\"https:\/\/realsenseai.com\/wp-content\/uploads\/2018\/12\/compare_blog.png\" alt=\"\" width=\"680\" height=\"247\" srcset=\"https:\/\/www.realsenseai.com\/wp-content\/uploads\/2018\/12\/compare_blog.png 680w, https:\/\/www.realsenseai.com\/wp-content\/uploads\/2018\/12\/compare_blog-300x109.png 300w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/>\n\nLooking at the same size area on the pictures, notice the RealSense D415 has a higher pixel density, which means it\u2019s more accurate for any given area than the RealSense D435 at the same points. While this may not matter in some cases, such as object avoidance or people detection, when accuracy is paramount (3D scanning), the RealSense D415 will provide a better, more accurate scan.\u00a0 In short, the RealSense D415 is more than 2x more accurate than the D435.\n<h5>Min Z Differences<\/h5>\nNext, let\u2019s compare \u201cmin Z\u201d or the distance from your depth camera to the object being captured. The RealSense D435 depth camera has more depth noise (&gt;2x) at any given range compared to the RealSense D415 depth camera, and it does have a smaller minimum operation distance (~0.5x) at the same resolution. This means you can get closer to the camera. For example, at 848 x 480 resolution, the RealSense D415 depth camera has a min Z of about 29 centimeters, whereas the RealSense D435 depth camera\u2019s min Z is 17 centimeters.\n<h5>Closing Thoughts<\/h5>\nThe RealSense D415 depth camera provides the best performance across a variety of use cases. The RealSense D435 depth camera is best for use cases that require as wide a FOV as possible.
