MotionCam-3D Quick Start Guide for Engineering Sample

05/2020

MotionCam-3D Winner of the VISION Award 2018, Systems Innovators Award 2019, and ranked among the inVISION Top Innovations of

2019, MotionCam-3D® by Photoneo® is the highest-resolution and highest-accuracy area-based 3D camera for scanning in

rapid motion.

Introduction Thank you for choosing Photoneo’s MotionCam-3D. Please take a few minutes to read through this manual to become

familiar with the device and its operation.

MotionCam-3D is the highest-resolution and the highest-accuracy area-based 3D camera for scanning in rapid motion. It

uses Photoneo’s patented technology called Parallel Structured Light implemented in our custom CMOS image sensor. The

camera is able to capture objects moving as fast as 40 m/s and shoot at up to 20 FPS. The system processes ~15M 3D

points per second, providing sub-millimeter precision.

Photoneo has started to sell engineering samples of the MotionCam-3D while it is still in the development stage. This

allows customers to test out the camera’s potential and to prepare for significant advances in the field of 3D capturing,

machine vision and automation. While the engineering samples are functional and safe to use, the final parameters and

components are still being fine-tuned.

The MotionCam-3D is based on the PhoXi® 3D Scanner family. Therefore, some of its features are very similar to those of

the scanner, while some work differently. The purpose of this guide is to outline the differences in operation between the

scanner and the MotionCam-3D.

If you are not familiar with PhoXi 3D Scanners or PhoXi Control, we kindly ask you to read the following manuals to

familiarize yourself with 3D scanners and scanning software:

Scanning Resolutions

MotionCam-3D utilizes a custom CMOS sensor and Parallel Structured

Light technology to produce 3D point clouds of scanned objects.

In the case of PhoXi 3D Scanners, the measurement of depth is achieved

by projection of structured light patterns on the scene. This way the

scanner measures one 3D point corresponding to each pixel on the image

sensor. MotionCam-3D does not rely on structured light patterns and

instead uses laser sweeps for illumination. The CMOS sensor powering

MotionCam-3D can use different schemes of sub-pixels to simulate

different structured light patterns. (The simulation of different light

patterns is also referred to as Coding strategy later in this document.)

The different sub-pixeling schemes contribute toward a single 3D point

(single measurement).

The sub-pixeling mode (the way each 3D point is measured) is controlled by the Resolution parameter. There are 7

different modes numbered from 0 to 6. We introduce them in an arbitrary order for better clarity.

Resolution Modes Overview

Resolution mode Independent measurements

(sensor resolution) Point cloud resolution Coding strategy

Mode 2 - scanner 1680 x 1200 1680 x 1200 Selectable

Mode 6 - camera 560 x 800 560 x 800 Interreflections

Mode 5 - camera 560 x 800 560 x 800 Normal





Resolution Mode 2 - Scanner Mode

Mode 2 switches the camera to a high-resolution scanner mode usable for static scenes. In this mode, one 3D point

corresponds to one pixel in the sensor and all PhoXi Control functionalities behave the same way as they do for scanners.

The scanner mode uses the full working resolution of the image sensor - 1680 x 1200 pixels. Therefore, it is able to

produce almost 2 million 3D points.

All the other modes enable high-FPS camera performance with the ability to scan moving objects. Please note that the

following scanning parameters are unavailable when any of the high-FPS camera modes is selected: Coding Strategy,

Coding Quality, and recognition of Marker Space.

Resolution Mode 5 & 6 - Fast Camera Modes with Uneven Point Distribution

Mode 5 and Mode 6 produce a depth map in a native

resolution of 560 x 800. Frame acquisition is fastest in these

modes but the 3D points are unevenly distributed. See the

sub-pixeling diagram and the point cloud resulting from

scanning a plane in Figure 2.

Mode 5 and Mode 6 differ in the Coding strategy. Mode 5

simulates light patterns of the Normal Coding strategy and

Mode 6 simulates the light patterns of Interreflections. For

the majority of scenes, Mode 6 produces superior quality

scans. Mode 5 is left for testing purposes.

Figure 2: The sensor sub-pixeling diagram and the resulting point

cloud of a flat surface scanned in Mode 5 or 6.

Resolution Mode 3 & 4 -Fast Camera Modes with Even Point Distribution

Mode 3 and Mode 4 are extensions of modes 5 and 6,

respectively. They use secondary sensor measurements to

compute points located directly between the measured

points. The resulting depth map has the resolution of

1120 x 800. Secondary measurements are calculated in PhoXi

Control. Mode 4 simulates the light patterns of

Interreflections Coding strategy and usually produces scans

of higher quality.

When capturing a dynamic scene, Mode 4 is

recommended as it generally delivers the best quality

results.

points are direct measurements whereas the blue points are

secondary measurements. On the right is the resulting point cloud

of a flat plane.



05/2020

Resolution Mode 0 & 1 - Camera Modes with Regular Point Distributions

Modes 0 and 1 use sub-pixeling with the highest number

of direct measurements to achieve depth map resolution

of 1120 x 800. The method this resolution is achieved

with generally produces results inferior to Modes 3 and 4

due to higher computational requirements, increased data

transfer rates (~ 30 ms slower), and reduced light

efficiency resulting in higher noise levels.

flat plane in Modes 0 and 1.

Normals

The calculation of topological normals is currently possible only in the Single scan mode (not in the Free run mode) due to

the computational load. Computation of normals is by default turned off. The following utility can be used to turn the

computation of normals ON:

Please contact [email protected] if you require assistance.

Hardware Trigger & Daisy Chain

It is possible to set up several MotionCam-3D cameras to work synchronously by using the hardware trigger functionality

and GPIO outputs. This setup requires special cables provided upon request as the standard power cable contains only 2

wires for power input. In this setup, the end of the acquisition on one device triggers the acquisition on the second device

and vice versa. Please contact us for more information and assistance.

Static IP

Setting up a static IP for MotionCam-3D is not available at the moment. Please contact [email protected] for

assistance. This will be updated in a future version of PhoXi Control.
