Exposure time is the duration for which the camera’s sensor is exposed to light for each frame. It determines the level of exposure to light, thus affecting the brightness of the image. The longer the exposure time, the brighter the image; the shorter the exposure time, the darker the image.

Adjust according to the on-site environment. Generally, longer exposure times are used in darker environments, and shorter exposure times are used in brighter environments. The 2D image should not be too bright or too dark, and the surface features of the target object should be clearly visible.

The following content only demonstrates the effect of changing exposure time on the image. In actual situations, image effects will vary depending on the scene and parameter settings.

Gain is the multiple by which the signal is amplified during image acquisition. It is used to increase the brightness of the image.

When the environment is dark, the image gain can be appropriately increased, but it should be noted that increasing the brightness will increase the noise in the image. Therefore, it is necessary to adjust it according to the actual situation to minimize the impact of noise while ensuring the brightness.

The following content only demonstrates the effect of changing gain on the image. In actual situations, image effects will vary depending on the scene and parameter settings.

Exposure time affects the density, quality, and noise level of the point cloud. Longer exposure times produce denser point clouds but may decrease quality and increase noise; shorter exposure times improve quality and reduce noise but may result in lower point cloud density. Exposure times that are too short or too long can lead to missing point cloud information.

Adjust according to the characteristics of the workpiece. Dark-colored workpieces typically use longer exposure times, while light-colored workpieces typically use shorter exposure times.

Gain affects the brightness, contrast, and noise level of the point cloud. High gain increases brightness and contrast but may increase noise; low gain has the opposite effect.

Select an appropriate gain to balance brightness and noise, ensuring point cloud quality.

Controls the camera to scan each sub-area sequentially and integrate the data from each sub-area to generate complete data. Using laser partitioning for capture can reduce ambient light interference, thereby improving image quality and signal-to-noise ratio.

The more partitions, the higher the data quality, but the capture time will be correspondingly longer. Please select parameters that can meet the image accuracy and speed requirements according to the actual situation.

Controls the encoding method of the laser projection system during scanning, mainly affecting scanning speed and accuracy.

Point cloud smoothing can be used to reduce depth fluctuations in the point cloud, making it closer to the real object surface, but some surface details of the object will be lost.

Used to fill gaps in the point cloud.

Used to clean up noise in the point cloud data, specifically those points that are isolated from the target point cloud.

When enabled, the camera will turn on the LED during capture to provide better lighting conditions, helping to improve image quality.

In low-light environments where image quality cannot be improved even by adjusting exposure time and image gain, consider enabling the LED fill light function.
