The world’s most advanced 3D recognition technology that can be used in sunlight, our 3D range image camera can recognize physical objects in the imaging space at up to 60 FPS. It obtains spatial information of an object in three dimensions without the influence of sunlight or shadows, even in darkness.

Application possibilities further expanded by utilizing spatial information

Customers can develop their own applications using the spatial information obtained by the camera. For example, an target object can be easily recognized and separated from a complicated background. Moreover, it is possible not only to check whether or not any object exists but also to measure the height, width, and location of an object, as well as select only objects that have a specific shape or move in a specific direction.

New imaging technology offering more sophisticated solutions

New technology not affected by environmental conditions

This new technology can be used at any time day or night, indoors or out, because it is free from the influence of sunlight and shadows, unlike 2D image processing or stereo vision that uses two or more cameras to measure distances from the cameras. Moreover, by processing the spatial information, this technology enables separation and selection of objects regardless of the scene’s background color and contrast.

Comparison with existing image capturing technology

∗"disparty" : The difference in image seen by two or more cameras.

20,000 points of distance data can be measured at the same time

The common range finding method can be measured at a certain point only. The Range Image Camera can measure at 20,000 points at the same time and can recognize the targets as 3 dimentional objects.

Comparison with existing Range–Finding technology

	3D range image	Laser scanning
Method	Measures the time of light that takes to hit an object and return, Getting 20,000 points range data at the same time makes 3D range image.	Measures the time of light that takes to hit an object and return. Scanning a rotating polygon mirror makes two-dimensional range data.
Distance resolution		(Superior in precision of distance measurement)
Outdoor use
Use in darkness	(Possible)	(Possible)
Scanning rate	(60 range images per second)	(20-60 range lines per second)
Detection range	3D: measuring approx. 20,000 points at the same time	2D only: scanning one optical axis

∗Laser Scanner is sometimes used swinging the horizontal scanning Laser Scanner vertically to get 3D Range Image.
