Software-defined 3D time-of-flight camera

Delta, the provider of power management and industrial automation solutions, will be launching the high-speed DMV-T time-of-flight (ToF) smart camera. Not only does the 3D camera offer a high capture speed of up to 60 frames per second, large scanning distance up to six metres, also it is the first software-defined 3D ToF camera in the market.

With a built-in processor and as well as sophisticated DIAVision software platform, allows the system integrator to develop their algorithm in the DMV-T, to create their own smart applications. It is suitable for logistics warehouse automation industries.

“Due to industrial automation rapidly developing, we see more and more customers adopt machine vision for robotic guidance, object detection and inspection and even edge safety applications,” said Chia-Wei Yang, General Manager of Smart Sensor & Meter LOB, Industrial Automation Business Group, Delta Electronics. Transitioning to 3D, observing that most applications needed to be done with an extra industrial PC to process. “To minimise investment but maximise the flexibility of application, the DMV-T integrates a dedicated processor and introduces the DIAVision platform to bring the hardware into another intelligent level as a software-defined 3D ToF smart camera for easier integration into a wide range of processes.”

Hardware-software integration to fulfill SMART applications

The DMV-T employs an ARM Dual Cortex-A53 CPU as well as FPGA enabling the camera to accomplish the 3D vision process from image capture to output. It inspects large items with its built-in image-stitching algorithm without the need for an industrial PC. Besides, with the intelligence inside, another highlight of the DMV-T is the combination of its vision platform software, DIAVision.

Offering an intuitive and convenient interface, users have an easy-to-use application-specific solution with a vision application repository open to third-party partners. Moreover, integrators and operators can create applications that run on the camera itself, reducing the components that need to be installed inside other equipment and saving space. Furthermore, the DMV-T with DIAVision can connect to the Delta Service DIACloud and support web browsers for anywhere, anytime data access. 

Detection and deployment to optimise measurement

The Delta DMV-T ToF camera incorporates a Sony IMX image sensor that operates in conjunction with a powerful built-in processor to offer 640×480 pixel resolution and 60 frames per second capture speed with owned ISP compensation allowing for high accuracy. The camera uses in advanced robotics applications that require object position and status feedback such as pick-and-place, shelf position calibration as well as object dimension measurement. And its detection time is shorter than the leading products in the same conditions. The camera rapidly measures depth by calculating phase differences between the carrier frequency of the active light it emits and the reflected light coming back from the object. This makes the interoperability between multiple mobile robotics in the field. In addition, with the APP on both DIAVision and DIACloud that help user to deploy the APP to multiple DMV-T simultaneously.

Pprotection to achieve outstanding safety in a noisy environment 

The DMV-T with IP67 ingress protection that ensures the operability in harsh environment, moreover, with specific industrial certificated that avoid the environmental and radiation effect between multiple mobile robotics (e.g. AMR/AGV).

Solution for the warehouse and logistics industries

With high specifications of sensor, processor, and processing capability, machine makers as well as system integrators for logistics and warehouse management can rely on the DMV-T for a variety of applications. For instance, the DMV-T can also be part of the li-ion battery warehousing system. By mounting at the front of the forklift, the DMV-T can help detect shelf positions and adjust fork angles in accordance with shelves that are crooked due to battery weights. It increases operational efficiency and the hardware availability of equipment for smooth pick-and-place movements. In addition, compared with LiDAR, the DMV-T captures a wider image range, which enhances the ability of the AGV to sense and avoid obstacles in the logistics fields.
