Introduction to LiDAR
LiDAR stands for Light Detection and Ranging. It is a technology that uses laser light pulses for contactless distance measurement. More information is available on our blog: https://www.blickfeld.com/blog/what-is-lidar-sensor/.
Blickfeld LiDAR Sensors
Blickfeld LiDAR sensors use the time-of-flight method to measure the distance to objects. The sensor calculates the distance by measuring the time between the emission of a laser pulse and the detection of the light that bounces off the object. The sensors scan in three dimensions using Blickfeld’s proprietary MEMS scanner technology. More information is available on our blog: https://www.blickfeld.com/blog/mems-technology-for-lidar/
Choose the Qb2 for a large field of view, high resolution, and advanced data processing capabilities. Cube 1 is an excellent alternative when low weight and dimensions are particularly important or when the budget is limited. The Blickfeld QbProtect is specially designed for advanced security applications.
Choose the standard version if you require a small device footprint and weight and if the ambient temperature at the operating location is expected to not exceed 40 °C. If higher temperatures might occur, choose the Extended Temperature Range (ETR) version.
QbProtect is based on Qb2 hardware, with a specially designed software explicitly for security applications. Users can configure their own security zones as well as alarm logic for reliable alarm generation customized to their needs.
You need an end device with a recent internet browser to configure the device and view data output. The Cube 1 standard variant comes with a power supply unit with the appropriate connector and an ethernet cable for data transmission, while the Cube 1 Outdoor, Qb2 products and QbProtect only require Power over Ethernet power supplying equipment. Blickfeld offers a range of optional accessories for mounting and cabling the devices.
The Cube 1 ships with a matching 12 V DC power supply. Maximum ratings are 10 – 26 V DC. Cube 1 Outdoor, Qb2 devices and QbProtect are powered via Power over Ethernet (PoE). You need a PoE power-supplying equipment such as a PoE switch or injector that supports the IEEE 802.3af and/or IEEE 802.3at standard. These are the most common PoE standards.
Cube 1 sensors ship with a mounting bracket that provides a standard 1/4″-UNC camera thread. Blickfeld offers different mounting options, including a camera mount that provides a standard 1/4″-UNC camera thread and a pan tilt mount which allows for flexible mounting of both Qb2 variants and QbProtect to both walls and poles. For QbProtect, the dual sensor mount and weather protection roof are especially useful for securing fences. Contact sales@blickfeld.com for further information.
CAD data are available for download for all current sensor models at https://www.blickfeld.com/resources/.
The web interface of Blickfeld sensors is independent of the OS used but requires a recent internet browser.
The data rate is variable and depends on the number of detected echoes, however, maximum values can be specified. For Cube 1, a maximum of 6 MB/s applies with one evaluated echo per sampled point. With three evaluated echoes, the maximum data rate can reach up to 8 MB/s. Qb2 and QbProtect devices can require up to 10 MB/s. To reduce the bandwidth, the refresh rate can be lowered from seconds up to several hours.
The Qb2 and QbProtect support the IEEE 802.11 b/g/n WiFi standards in the 2.4 GHz band.
The antenna is not necessary for operating the sensor. It is only required when using the WiFi functionality. Please note that WiFi operation is only permitted with the Blickfeld-authorized antenna.
Cube 1 sensors use their own data format (.bfpc) for point cloud data. Tools are available to convert this format to standard .vtu or .csv formats. Additionally, point cloud data can be retrieved via the API of the sensor and saved in any user-defined format via the user’s development environment.
Blickfeld sensors come with their own Application Programming Interfaces. For the Cube 1 product line as well as Qb2 and QbProtect, Blickfeld offers client libraries supporting the C++ and Python programming languages. However, users can implement clients in further languages using the native sensor APIs. Additionally, Blickfeld provides drivers for the Robot Operating System (ROS). Further information and resources can be found at https://www.blickfeld.com/resources/#developer-tools.
QbProtect can be integrated into your own existing systems via common interfaces (via TCP/IP & MQTT in VMS or Web I/Os, etc.), enabling the generation of ONVIF-compatible events for alarms.
No additional software is needed to configure and operate the sensors except for a recent internet browser.
Blickfeld sensors can be integrated into other software using the sensor’s Application Programming Interfaces (APIs) and client libraries. Additionally, Blickfeld offers perception software, which transforms raw point cloud LiDAR data into actionable insights, accessible within your web browser. Qb2 and QbProtect sensors come with multiple software on-device features. Percept PC is currently available for Cube 1 sensors.
Yes. You can find corresponding ROS(2) drivers on the Blickfeld website at https://www.blickfeld.com/resources/.
Sensors can interfere with each other if they face each other directly or illuminate the same highly reflective objects in their field of views. However, due to the unique optical design of Blickfeld LiDARs, this interference is kept at a minimum. Double images or similar artifacts cannot occur. Merely a slightly increased false detection rate will be noticeable in worst-case scenarios.
Yes, the Blickfeld Percept software is capable of fusing the point clouds of several Cube 1-type sensors. With Qb2 and QbProtect, this swarm feature is integrated into the device firmware.
QbProtect can be integrated into existing security systems via common interfaces (via TCP/IP & MQTT in VMS or Web I/Os, etc.). Enabling the generation of ONVIF-compatible events for alarms. it is also compatible with video management systems.
Thanks to the intrinsic light source, Blickfeld LiDAR sensors are independent of ambient lighting and therefore guarantee reliable detection both in the dark and in strong sunlight.
Qb2 as well as QbProtect incorporate sabotage and malfunction alarms using the internal IMU and constantly monitor their optical performance to detect intentional obstructions or dirt on the sensor.

Visit https://www.blickfeld.com/resources/ to download data sheets & manuals.
Cube 1: Scans about 90.000 measurement points per second (single return).
Qb2/QbProtect: Scans about 180.000 measurements per second (single return).
Cube 1: The highest resolution that can be configured is 0.4° in the horizontal direction and 0.150° in the vertical direction.
Qb2/QbProtect: The highest resolution that can be configured is 0.25° in the horizontal direction and 0.225° in the vertical direction.
QbProtect is able to detect objects based on their true object size via pre-defined parameters that specify the size of an object (the distinction between small objects, humans, and big objects). Therefore, an exact statement can be made on what kind of object has triggered a detection/intrusion.
Blickfeld’s Cube 1 Outdoor, Qb2 and QbProtect sensors feature weatherproof housings with IP65 and IP67 ratings, respectively.
Blickfeld specifies detection ranges for its sensor in terms of a standard 10% reflectivity target, which resembles a strongly absorbing (dark) object. The corresponding value can be found in the sensor data sheet.
Highly reflective objects can be detected over long distances.
Precipitation and other atmospheric disturbances such as smoke, dust, or fog do not increase the false detection rate of our LiDAR sensors but can influence the detection range.
Blickfeld LiDAR sensors are offered with IP6X-rated housings, which are dust-proof. Additionally, dust can affect the performance of the sensor in two ways. In the air, dust can increase the false detection rate of LiDAR sensors. However, Blickfeld sensors perform very well in such scenarios, as long-term installations inside waste facility bunkers, silos, and similar locations have shown. Additionally, dust can settle on the optical aperture of the sensor, which decreases the detection range. However, this is only a problem in extreme cases, such as inside silos containing powdered substances. For such cases, Blickfeld can offer a pneumatic cleaning as an add-on to the sensor.
Blickfeld’s LiDAR sensors support up to three returns per laser pulse, allowing them to detect multiple objects at different distances within the same beam path. This feature is particularly useful in scenarios where a laser pulse encounters multiple surfaces, such as when scanning through vegetation or semi-transparent materials like glass.
Without multiple returns, a LiDAR sensor typically registers only the first object hit, potentially missing partially obscured objects behind it. With multiple returns, the sensor can capture depth information more accurately, distinguishing between different layers of a scene.
For example, in forested areas, a single laser pulse may reflect off treetops, branches, and the ground, creating multiple returns that provide a detailed representation of the landscape. This capability is valuable in applications like terrain mapping and environmental monitoring.By default, the sensor is configured for single-return mode, as increasing the number of returns can lead to a higher false positive rate at short distances.
