TOF Camera

Zoom
With a real-time sensing function, the camera measures the distance to the object by using the time of flight of light.
Using a single sensor, the camera captures depth and color images simultaneously from the same viewpoint.
The TOF camera lineup includes a lightfastness type and a small type suitable for use as a built-in camera (now under development).
 

Use cases

Case study: TOYOTA MOTOR CORPORATION

The AI basketball robot “CUE3/CUE4” developed by TOYOTA MOTOR CORPORATION is equipped with a Panasonic TOF camera.
CUE3 measures the distance to goal and the aiming direction with high accuracy, being able to make a shot from the free-throw line or three-point line and even a long shot from the center line. See the video below.
With its highly appreciated ability to obtain high-definition/high-precision depth image information, the Panasonic TOF camera has been adopted as a built-in camera of CUE3/CUE4.

Features of TOF camera

Captures images without parallax shift.

Captures RGB images and distance images with a single sensor. As images without parallax shift can be captured from the same viewpoint, no shift correction is required. Contributes to the development of high-precision detection apps.

The product lineup also includes a high ambient light resistance type.

This type of camera is usable in sunlight so it can be used for various outdoor activities such as harvesting of crops.

The angle of view can be selected based on the scene to be shot.

The product lineup includes the standard type (H55xV41) and wide-angle type (H90xV70). You can choose the type depending on your purpose.

Reduces interference between TOF cameras.

Interference hardly occurs even when using multiple TOF cameras simultaneously, and thus prevents significant measuring errors.

A wide dynamic range function extends the measuring range.

It extends the measuring range under conditions with distance difference, light/dark difference, and reflectance difference, enabling you to capture images with high accuracy.

New Product

New platform TOF camera NC2 (under development)

Also supports AGV/AMR, such as unmanned guided vehicles.

A new platform to achieve required lower costs and make connection with later stage boards on the user side as well as development easier.

Features

Lower the product price to contribute to cost reductions in the site where it is used.

Reviewing the circuit block and lens has allowed a 50% reduction in price compared to the current high light resistance models (* comparison of the total price for camera + I/F).

Compact size that enables effective use of the space of the housing.

A 70% reduction in volume has been achieved by optimizing circuit design and heat dissipation housing design.

The MIPI-I/F interface is installed.

It is possible to connect this to a computer with a general-purpose board, or a later stage board. Dedicated board or SDK is not required. Improves the user-design flexibility.

Low power consumption has been achieved.

Reducing the power consumption reduces the burden on battery-powered products, including onboard AGV.
