How to use a 3d solid camera

Compared with standard cameras, 3d physical cameras have more gorgeous effects and more settings, which is also the difference between cameras and SLR cameras. The brightness and exposure of the pictures taken by the physical camera can be controlled freely, which will relieve a lot of pressure on the subsequent ps. So how to adjust the parameters of 3d physical camera and how to use it? Come with me to read the article! First, how to adjust the parameters of 3d solid camera

1, projection

(1) Projection brightness: The brightness projected by the projector is divided into three levels: high (high brightness), normal (normal brightness) and low (low brightness). Usually dark objects are high and reflective objects are low.

(2) Color of projected light: The colors projected by the projector can be divided into white and blue. White is used by default.

2. Exposure time

You can choose 1, 2, 3 exposure. Using multiple exposures can improve the imaging of objects with different reflection characteristics.

3. Exposure time

According to the exposure times, different exposure times are set, so that the camera can collect 3D images respectively and fuse the results.

Dark objects usually use a long exposure time, and reflective objects usually use a short exposure time. For laser cameras, the exposure time must be a multiple of 4.

4. Camera gain

Used to improve the brightness of the image. When the expected brightness value cannot be achieved by setting the exposure time, it is suggested to increase the gain, but image noise may be introduced. The default value is 0dB, and the adjustment range is 0~ 16dB.

Second, how to use a 3d physical camera

1. Step 1, set the camera plane position and viewpoint position, imagine yourself as a photographer, and find a camera plane position and camera illumination position in the virtual space.

2. Step 2: Set the camera and viewpoint height.

Adjust the camera position, viewpoint position and focal length to the most suitable position.

What about the deformation of indoor furniture when editing the camera adjustment parameters-camera FOV-FOV, want to expand the indoor view without deforming the furniture?

Generally, it is an adjustment method: you can try cameracorrection.

Select camera >>& gt modifier & gt> camera & gt& gt& gtCameracorrection or select camera >; & gt& gt right-click >> & gtapplycamerarcorrection modifier.

This can make your model line as horizontal and vertical as possible, and the deformation is more active.

3. Start shooting.
