Lucid 3d Camera
Jules Altier
So I tried firstly the SDK Lucid app, for testing if the camera was working properly. And It gave me some problems because of the private net where I work, because the net was blocking somehow the camera, so after disconnecting the computer from the net It finally worked, and with the Lucid camera app I was able to see through the camera.
After knowing that, the camera was able to communicate with the computer, I tried to use the Labview again, and it gave me the same error. So I searched the error and followed the Labview recommendations that I found, and also disabled the firewall, but I was not able to connect the camera.
In this NI pagen with some posible solutions, in the very last point, I found that my net card can't handle big packages. By default in my Labview was in 9000, after changing to 1500 I made a snap and it work perfectly.
Step 1: Screw on the lens tube ring that comes with the LUCID lens tube accessory. Turn the ring until there is contact with the front base of the camera (b). The C-mount should also extent passed the ring by a small amount, approx. 0.3mm (a).
Connect Cable to Camera
Screw in the M12 X-Coded Cat 5e/6/6a cable to the camera. The camera will briefly blink red upon power-up and then start blinking green once it is ready to stream.
Connect Cable to Camera
Connect the M12 X-Coded side of your Cat 5e/6/6a cable to the camera. The camera will briefly blink red upon power-up and then start blinking green once it is ready to stream.
Connect M8 Power Supply Cable to the Camera
Connect the power supply to an outlet and then to the M8 port on the Helios. The camera will briefly blink red upon power-up and then start blinking green once it is ready to stream.

Firmware Update Process
The Firmware Update page will show the progress of the update. During the update, the camera will not be accessible for control or image capture. The update may take a few minutes to complete. Please refrain from removing power from the camera during the update.
The Lucid Air is equipped with up to 32 on-board sensors, including long range Lidar radar, short-range radar, surround view monitoring cameras, front multifunction camera, rear view camera and ultrasonic sensors. These cameras are used for the DreamDrive ADAS, advanced driver-assistance system, technology and will be used for future DreamDrive Pro capabilities.
It doesn't look like arena_camera_ros or camera_aravis support that setting, but you can use arv-tool from Aravis (also installable with apt as aravis-tools). I have used the following commands to enable and query ptp status on Lucid Triton cameras:
The camera lucida projects an optical superimposition of the subject being viewed, onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective.
The basic optics were described 200 years earlier by the German astronomer Johannes Kepler in his Dioptrice (1611), but there is no evidence he constructed a working camera lucida.[4] There is also evidence to suggest that the Elizabethan spy Arthur Gregory's 1596 "perspective box" operated on at least highly similar principles to the later camera lucida, but the secretive nature of his work and fear of rivals copying his methods led to his invention becoming lost.[5] By the 19th century, Kepler's description had similarly fallen into oblivion, so Wollaston's claim to have invented the device was never challenged. The term "camera lucida" (Latin "well-lit room" as opposed to camera obscura "dark room") is Wollaston's.[6]
While on honeymoon in Italy in 1833, the photographic pioneer William Fox Talbot used a camera lucida as a sketching aid. He later wrote that it was a disappointment with his resulting efforts which encouraged him to seek a means to "cause these natural images to imprint themselves durably".
In 2001, artist David Hockney's book Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters was met with controversy. His argument, known as the Hockney-Falco thesis, is that the notable transition in style for greater precision and visual realism that occurred around the decade of the 1420s is attributable to the artists' discovery of the capability of optical projection devices, specifically an arrangement using a concave mirror to project real images. Their evidence is based largely on the characteristics of the paintings by great artists of later centuries, such as Ingres, Van Eyck, and Caravaggio.
The camera lucida is still available today through art-supply channels but is not well known or widely used. It has enjoyed a resurgence as of 2017 through a number of Kickstarter campaigns.[7]
The name "camera lucida" (Latin for "light chamber") is obviously intended to recall the much older drawing aid, the camera obscura (Latin for "dark chamber"). There is no optical similarity between the devices. The camera lucida is a lightweight, portable device that does not require special lighting conditions. No image is projected by the camera lucida.[citation needed]
In the simplest form of camera lucida, the artist looks down at the drawing surface through a glass pane or half-silvered mirror tilted at 45 degrees. This superimposes a direct view of the drawing surface beneath, and a reflected view of a scene horizontally in front of the artist. This design produces an inverted image which is right-left reversed when turned the right way up. Also, light is lost in the imperfect reflection.[citation needed]
Wollaston's design used a prism with four optical faces to produce two successive reflections (see illustration), thus producing an image that is not inverted or reversed. Angles ABC and ADC are 67.5 and BCD is 135. Hence, the reflections occur through total internal reflection, so very little light is lost. It is not possible to see straight through the prism, so it is necessary to look at the very edge to see the paper.[8]
The instrument often came with an assortment of weak negative lenses, to create a virtual image of the scene at several distances. If the right lens is inserted, so that the chosen distance roughly equals the distance of the drawing surface, both images can be viewed in good focus simultaneously.[citation needed]
If white paper is used with the camera lucida, the superimposition of the paper with the scene tends to wash out the scene, making it difficult to view. When working with a camera lucida, it is often beneficial to use toned or grey paper. Some historical designs included shaded filters to help balance lighting. [citation needed]
As recently as the 1980s, the camera lucida was still a standard tool of microscopists.[4] It is still a key tool in the field of palaeontology. Until very recently, photomicrographs were expensive to reproduce. Furthermore, in many cases, a clear illustration of the structure that the microscopist wished to document was much easier to produce by drawing than by micrography. Thus, most routine histological and microanatomical illustrations in textbooks and research papers were camera lucida drawings rather than photomicrographs. The camera lucida is still used as the most common method among neurobiologists for drawing brain structures, although it is recognised to have limitations. "For decades in cellular neuroscience, camera lucida hand drawings have constituted essential illustrations. (...) The limitations of camera lucida can be avoided by the procedure of digital reconstruction".[9] Of particular concern is distortion, and new digital methods are being introduced which can limit or remove this, "computerized techniques result in far fewer errors in data transcription and analysis than the camera lucida procedure".[10] It is also regularly used in biological taxonomy.
Yes, you can use the LUCY if you wear glasses. However, it may not work well if you wear bifocals, trifocals, or progressive lenses. Basically, the LUCY enables you to see two things at the same time laid over each other. So you see your paper and the subject at the same time. If you have difficulty seeing near and far objects without trifocals, then when the two images are transposed over each other you will only be able to see either one or the other clearly.
The LUCY Drawing Tool is an improved adaptation of the classic camera lucida. Serving as an art tracing tool for drawing and painting, it functions like an art tracing projector without requiring batteries or bulbs. The LUCY is based on drawing tools that have been used by the Old Masters for centuries, so this drawing aid stands out as the best gift for artists looking to merge classic techniques with today's technology. Experience art like never before with the LUCY Drawing Tool!
Hi:)
I run into the same problem with PHX023 camera. I set AutoNegotiate off, and StreamPacketSize to 9000, and it still was not working for me. What values should I set them to? And is it possinble there are other values to set?
