What kind of 3d camera do you choose?

3d free physics, which is the target camera?

3d free physics, target camera can be used.

1, one has a target point and the other does not.

2. If you are making renderings, you usually use the target camera.

3. If you do game animation, you usually use a free camera. TeledyneDalsa, LMI and illness are all fine.

The research of three-dimensional stereoscopic vision has important application value and is also one of the important topics in the field of computer vision research. Stereo vision system can automatically identify and locate the target in the field of view, and can realize the on-site calibration of the system in complex background environment. By identifying and locating the feature points on the moving human body, and analyzing the data, the three-dimensional coordinates, postures and relative distances of the feature points of the moving human body are further obtained. With the deepening of research, its application will be more and more extensive, providing strong technical support for the development of the industry.

At present, 3D machine vision is mainly used for grading fruits and vegetables, wood, cosmetics, baked goods, electronic components and medicines. It can improve the production capacity of qualified products and scrap inferior products in the early stage of the production process, thus reducing waste and saving costs. This function is very suitable for imaging product attributes such as height, shape, quantity and even color.

But our RegemMarr evocation gold code is also very good! Built-in rich IO interface to support complex field requirements. Integrate multiple groups of controllable light sources to realize independent control of light source shunt. It is not only an intelligent code reader, but also a good helper in business. The functions of output statistics and piece counting are beyond imagination.

Through the official WeChat platform (WeChat official account number: RegemMarrRegemMarr research code), you can know the latest developments of the company and various industry information at the first time, and you can also interact instantly. At the same time, you can apply for maintenance online, inquire about outlets, warranty period and so on. , get professional services quickly.

What cameras are commonly used for 3D rendering?

The performance and physical parameters of the two cameras are different.

First of all, we usually choose our own camera, because most people have a 3D foundation before learning VR. In addition, the camera supports different renderers, which is more stable. Finally, there is another reason that cannot be ignored: it is best to use your own camera for animation.

Secondly, as for why there is a VR camera, it is because of the "matching" of related performance. Compared with the standard light source, the light source of VR has a strong attenuation, and the effect is more layered and more "realistic". Therefore, VR will be sought after by commercial renderings (in fact, because parameters are simple and easy to control). In the same way, the setting of VR camera is simpler, and it can capture attenuation better, but only if the illumination of light needs to be increased by 10~30 times. In other words, if you want to change the angle temporarily, but don't play the VR camera, you get an overexposed picture. It is more complicated to use.
