I've been searching the forum and read all the manuals avalible for Context Capture Master and the process of aerotriangulation and productions of orthophotos. But I'm still uncertain on how the process should be conducted in order to achive best result…

I'm desperately searching for a page I've recently seen on the forum (or was it the Wiki?), describing the maths and process on how to determine a good distance between GCP;s on a large land survey project. - Is there anyone out there who know what…

For our ContextCapture projects we have two customers. One customer needs Nad83(2011) NCSP NAVD88 Geoid 18 (xyz units us survey foot), the other customer needs Local Space Rectangular. The difference between the two SRS's is normally a scale factor. Knowing…

HEllo good CC community, This is a question I've been wanting to ask for a while, Although I'm very familair with the concept of Keypoints and control points, every time I try to generate keypoints and control points to actually give scale to…

Hi everyone, I have a question regarding control points and how many photos to assign control too. I know the minimum is 3 photos for 3 different control points. I am processing photogrammetry for utility excavations and need the photogrammetry to…

I created a project. I went to Tools and saw that April tags need to be at least 35x35 pixels. If I am flying a job with a Phantom 4 RTK at an altitude of 71m AGL that gives me a GSD if 1.95 cm/px If we calculate that out to 35px by 35px that gives us…

My school is undergoing a campus modeling project and we only have a cheap VLP-16 LIDAR puck scanner that we have been able to use and process through KAARTA. Because of the minimalistic setup, there is no GPS on the unit and no geographical reference…

I'm using Sony A7R II with 28mm lens and I'm curious why my focal length change slightly? it's a prime lens and manufacturer spec says it's 28mm and the aero-triangulation optimized the focal length in the range of 27.13mm - 27.20mm for different photogroups…

I am using high definition RGB oblique and nadir imagery without GPS or roll/pitch/yaw data. Will context capture successfully stitch imagery to form the mosaic mesh model? We aren't using LiDAR due to a lack of geographic relief for this particular problem…

I used a DJI Inspire 2 w/X4S camera to obtain nadir and 45 deg oblique imagery in both directions for the use of reality modeling in ContextCapture. Extensive ground control was placed and recorded to constrain the model. After running a quality check…

用contextcapture軟體 要點 Control point Checkpoint 是否可以直接 搜尋 施測 座標的位子 讓點 Control point Checkpoint 速度更快一點。 不需要一張一張照片尋找 Control point Checkpoint所在的位子 請問是否有跑Orthophoto(tiff檔案) 的步驟 我跑出來都是黑色圖片

Hello all, After a lot of trial and error, we managed to produce a 1.2sq km model of Downtown Dubai but we still face a couple of challenges with regards to GCP's and using the KML Polygon for the water surface as you can see below. During the AT…

Hello, Does CC support D-RTK GNSS by DJI A3 series flight controllers ?? The reason I'm asking is simply...normally we use control points for our aerial imagery but this time we want subcontractor to do the hard work and provide us with aerial photos…

I've imported photos from a DJI Phantom 3 and performed an AT on them, it works OK except for a bit of radial distortion. I then bring in and mark my ground control and do another AT using the setting 'Use control points for adjustment', but after AT…

Hallo! I am having big problems with importing Control Points in ContextCapture via Control Points Editor. Please check my Attached TXT file where I have GCPs from Local Survey team. Software does not want to import them. I have tried several formats…

Hello. I have a problem importing point clouds in ContextCapture.My task is to combine photos and scannings from Faro Focus 3D X330. I have taken GCPs with ASHTECH(i use same GCPs to photographs and to scannings). I first made the Aerotriangulation to…

Hi! I'm testing the accuracy of the photogrammetry process. So I use GCP and check point (CP). When I use only GCP the aerial triangulation's error is not relevant and the result is good but when i use GCP and CP the CP's error is higher than GCP's…

I need to introduce Control Points in ContextCapture. How I can import a list of coordinates X,Y,Z from .txt file?
