Author: Wang Yang Xi, Texas Instruments (TI) DLP® Products Marketing Manager Video projectors used in theaters, classrooms, or corporate meeting rooms are designed to meet the needs of the human eye. However, not all projectors are designed to meet the needs of viewing. Many industrial applications, such as 3D machine vision and dynamic projection mapping, require industrial projectors with higher frame rates and lower latency. This is especially important in factory automation where industrial projections are used to properly pick objects, position objects, or place them in place. You may be puzzled by the importance of frame rate and latency. Literally, a frame per second means the number of images that can be flashed on the screen per second. Combined with a high-speed camera, the higher projector frame rate captures visual information in a shorter period of time, which helps improve the accuracy and data throughput of the machine vision system. Foot 3D printed circuit board (PCB) inspection is an industrial application that benefits from high frame rates. It is used to check the proper amount of solder paste on the assembly line and the correct placement of the components, which helps to increase PCB yield. Latency is a very slight lag between the time an image is imaged and the time it is projected. Low latency is important for better synchronization between the projected image and the camera, which can cause a machine vision system like a robotic device to reach a designated location at the right time. Digital projection mapping is an application that benefits from low latency and is capable of tracking the projected object quickly and accurately. Now, there is a new demonstration that gives us a solution – a solution that runs at 1000 frames per second and 3 milliseconds per second is a huge technological advancement in this area. It includes the TI DLP7000 XGA chipset with a high-speed industrial camera and a personal computer to provide such high performance. While traditional consumer projectors can achieve frame rates up to 120 Hz, some of the high-speed chips in the TI DLP product library are specifically designed for industrial solutions, enabling frame rates up to 1900 Hz at 8-bit depth. The demonstration was co-authored by Tokyo Electronics Co., Ltd., one of the many DLP design network partners, and the University of Tokyo. From dynamic projection mapping to PCB inspection and factory automation, it undoubtedly gives us a glimpse into the future of machine vision.
