![]() ![]() All objects at distances from 28cm out to infinity will be sharp. You can use pixelNumber to switch between horizontal and vertical resolutions. The field of view formula is the following:įov = 2*arctan(pixelNumber/(2*focalLength)) * (180/pi) The exact focal length can vary depending on the selected resolution and your own camera calibration. On Windows (SDK ≤ 2.2.0): C:/Users/YOUR_USER_NAME/AppData/Roaming/Stereolabs/settings/.On Windows: C:/ProgramData/Stereolabs/settings.You can retrieve the parameters of your camera using the ZED API with getCameraInformation().calibration_parameters.left_cam.

Both the D435 and D415 cameras yield the best quality depth maps at about 60–70 cm from the scene, according to the literature. It should be noted that the D415 depth camera yields better depth measurement results when the targeted object is close to the sensor, i.e., 1 m or less. This attribute improves the performance of this depth sensor when there are no unexpected fast movements during image capturing, but the image is static. The RealSense D415 sensor has a rolling shutter. Hence, if accuracy and precision are the main requirements in an application, e.g., avoiding obstacles in robotics application and in object detection, the D415 depth sensor gives much better results. Here, the FOV of the corresponding depth sensor is (H × V × D): 65° × 40° × 70°. The D415 depth camera has a narrower FOV (H × V × D): 69° × 42° × 77° for RGB camera, and this property results in a higher density of pixels, thus increasing the resolution of the depth map. The D435 depth camera also yields better depth measurement results when the targeted objects are a few meters away from the camera itself. Furthermore, this sensor has a global shutter that ensures a better performance in situations where lighting is unsatisfactory, while capturing fast movements in a scene, and reduces the effect of blurring in images. Therefore, this sensor is often used in automotive applications and in drones. Usually, visual assessment is used in practice for the characterization of resulted depth images. These are important parameters of depth sensors, and they can be easily observed by observing the measured depth maps of a scene, or object. Accuracy is the percentage of error with respect to the measured depth, while precision is the capability of the sensors to replicate the same measure in the same conditions. As a result, this depth sensor is suitable for applications where no great accuracy and precision are required, but where a global visual experience is more significant. The FOV of the corresponding depth sensor is (H × V × D): 85° × 58° × 90°. The D435 camera has a wider FOV (H × V × D-Horizontal × Vertical × Diagonal): 91° × 65° × 100° for RGB camera, which minimizes blind, black spots in the depth map, after which the acquired depth image is pleasing to the eye.
