What resolution and evaluation time should the camera have for image-guided robotics applications?

The ideal camera for vision-guided robotics applications should have both a sufficiently high resolution and low evaluation time to ensure the least possible impact on cycle time. 

Resolution, which describes the number of pixels in an image, is critical for sharpness and detail. For robotics applications, high-resolution cameras are of great importance because they enable precise detection and differentiation of objects. However, the required resolution depends on various factors, such as the size of the objects, the working distance and the speed of the system.

The evaluation time, also known as latency, is an important factor when selecting vision sensors. It indicates how quickly a sensor processes a received image and delivers a result. A low evaluation time is particularly important in applications that require a fast response time, such as object detection in robotics. A longer evaluation time can cause delays and affect the performance of the system.

Typically, vision sensor evaluation times range from a few milliseconds to a few seconds, depending on the application and the performance of the sensor. A fast evaluation time can increase system efficiency and improve overall performance.

It is important to note that resolution and evaluation time are closely linked. Higher resolution requires more data processing, which can affect the evaluation time. Therefore, it is necessary to find a balance between the two to achieve the best possible performance for the particular vision-guided robotics application. Overall, the optimal resolution and evaluation time depend on several factors, and it is important to consider both the size of the objects and the speed of the system when selecting the appropriate camera for robotics applications.
